    Description: Sexual dimorphism in selected extragenital tissues is described with emphasis on the molecular basis of the differences. Testosterone rather than 5 alpha-dihydrotestosterone appears to be the major intracellular androgen in organs other than skin and reproductive tract, but other steroid metabolites and their receptors are required to produce the diverse tissue differences observed in males and females. There is also evidence that multiple hormones from several endocrine glands are required to act in concert with androgens to produce and maintain their effects. Although many of the consequences of sexual dimorphism, such as body size and strength, have been evident for centuries, other differences between males and females such as disease incidence, response to drugs and toxins, and the metabolism and assimilation of dietary constituents have only recently been discovered.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bardin, C W -- Catterall, J F -- HD-13541/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1981 Mar 20;211(4488):1285-94.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7010603" target="_blank"〉PubMed〈/a〉

    Description: Throughout development, Mongolian gerbils engage in conspicuous naso-oral investigations of their social partners' mouth areas. The behavioral contribution of saliva-related stimuli in regulating oral-directed responses was studied during several important phases of the gerbil's social life. Weanlings were preferentially attracted to their mother's saliva, subadults at puberty preferred saliva of littermates to that of nonlittermates, and sexually experienced males preferred the saliva of estrous females to that of nonestrous females. The use of saliva as a discriminative cue during various developmental periods suggests that oral chemostimuli have a perennial role in regulating social interchanges.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Block, M L -- Volpe, L C -- Hayes, M J -- R03MH 27346/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1981 Mar 6;211(4486):1062-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7466378" target="_blank"〉PubMed〈/a〉

    Description: In a replicated experiment, nonbreeding winter populations of Microtus montanus were given supplements of rolled oats coated with 6-methoxybenzoxazolinone, a naturally occurring plant derivative. After 3 weeks of this feeding regime, samples from the populations demonstrated a high incidence of pregnancy in females and testicular hypertrophy in males. Control populations receiving rolled oats coated only with the solvent showed no reproductive activity. These results demonstrate that the presence of 6-methoxybenzoxazolinone in the plant food resource acts as the ultimate cue to trigger reproductive effort in Microtus montanus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berger, P J -- Negus, N C -- Sanders, E H -- Gardner, P D -- RR-07092/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1981 Oct 2;214(4516):69-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7025210" target="_blank"〉PubMed〈/a〉

    Description: Two maternally derived chromosome sets and both maternal histocompatibility antigen haplotypes were identified in the tissues of a malformed triploid acardiac twin that developed within the same chorion as its normal twin.

    Description: A summary of 111 studies identified in a survey of the world literature on familial resemblances in measured intelligence reveals a profile of average correlations consistent with a polygenic mode of inheritance.

    Description: The synthetic peptide NH2-Tyr-Pro-Phe-Pro-CONH2 (morphiceptin), which is the amide of a fragment of the milk protein beta-casein, has morphinelike activities and is highly specific for morphine (mu) receptors but not for enkephalin (delta) receptors. It is as active as morphine in the guinea pig ileum but much less active in the mouse and rat vas deferens. The discovery of this specific morphine receptor ligand substantiates the hypothesis of multiple opiate receptors. The ligand, which may be of physiological significance since a very similar, or identical, activity can be detected in enzymatic digests of beta-casein, may prove useful for further investigation of the functions of opiate receptor subtypes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chang, K J -- Lillian, A -- Hazum, E -- Cuatrecasas, P -- Chang, J K -- New York, N.Y. -- Science. 1981 Apr 3;212(4490):75-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6259732" target="_blank"〉PubMed〈/a〉

    Description: The milk sugar lactose is known to facilitate calcium absorption and has been shown to enhance the uptake of essential trace metals from the intestines as well. Its physiological role as the major carbohydrate source for suckling mammals is thus complemented by its ability to facilitate the absorption of necessary minerals. The studies reported here show that the intestinal absorption of lead and its uptake into blood, liver, kidney, and bone are also increased by lactose in young weanling rats. These data extend the known range of lactose facilitation of mineral absorption to a nonessential, toxic element, confirming the nonspecificity of its action on the gut. In addition, they suggest an explanation for some of the conflicting evidence regarding the prophylactic efficacy of milk in lead poisoning.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bushnell, P J -- DeLuca, H F -- ES-05147/ES/NIEHS NIH HHS/ -- New York, N.Y. -- Science. 1981 Jan 2;211(4477):61-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7444448" target="_blank"〉PubMed〈/a〉

    Description: The serum of lactating rats that have never been infected with the protozoan parasite Trypanosoma lewisi contains a rheumatoid factor-like immunoglobulin M (IgM). This IgM amplifies a specific immunoglobulin G (IgG) response to the parasite and accounts for the unusual resistance of previously uninfected lactating rats and their suckling pups to infection with T. lewisi. A similar rheumatoid factor-like IgM, which is induced late in the usual course of infection with T. lewisi in nonlactating rats, amplifies an earlier IgM response and terminates the infection. To our knowledge, this is the first description of a rheumatoid factor, which is classified as an autoimmune antibody, acting in a protective manner.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Clarkson, A B Jr -- Mellow, G H -- New York, N.Y. -- Science. 1981 Oct 9;214(4517):186-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7025211" target="_blank"〉PubMed〈/a〉

    Description: Averaged sensory-evoked potentials were recorded from the outer molecular layer of the dentate gyrus in naive rats and in rats conditioned to respond in the presence of an auditory stimulus. Two components (negative peaks) of the potentials were functionally distinguished in terms of responsiveness to unique or conditioned auditory stimuli. Each component was independently generated by a separate input pathway to the dentate gyrus: The perforant path provided an "insignificance" or "unexpected" feature of the sensory stimulus when appropriate, and the septum controlled the development of a second component as a function of the behavioral significance of the stimulus during the acquisition of auditory discrimination behavior. A reciprocal relationship between the peak amplitudes of both components of the average evoked potentials dependent on the relative behavioral significance of the sensory stimulus was observed in all animals during extinction and reconditioning of the sensory discrimination task. The findings indicate that the entorhinal and septal projections to the dentate granule cells are activated differentially by sensory stimuli as a function of their acquired behavioral significance to the animal.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Deadwyler, S A -- West, M O -- Robinson, J H -- New York, N.Y. -- Science. 1981 Mar 13;211(4487):1181-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7466392" target="_blank"〉PubMed〈/a〉

    Description: A new technique has been developed for identifying, in humans, dynamic spatiotemporal electrical patterns of the brain during purposive behaviors. In this method, single-trial time-series correlations between brain macropotentials recorded from different scalp sites are analyzed by distribution-independent mathematical pattern recognition. Dynamic patterns of correlation clearly distinguished two brief visuomotor tasks differing only in type of mental judgement required (spatial or numeric). These complex patterns shifted in the anterior-posterior and left-right axes between successive 175-millisecond intervals, indicating that many areas in both cerebral hemispheres were involved even in these simple judgements. These patterns were not obtainable by conventional analysis of averaged evoked potentials or by linear analysis of correlations, suggesting that the new technique will advance the study of human brain activity related to cognition and goal-directed behaviors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gevins, A S -- Doyle, J C -- Cutillo, B A -- Schaffer, R E -- Tannehill, R S -- Ghannam, J H -- Gilcrease, V A -- Yeager, C L -- New York, N.Y. -- Science. 1981 Aug 21;213(4510):918-22.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7256287" target="_blank"〉PubMed〈/a〉

    Description: The effects of long- and short-term administration of the tricyclic antidepressant desipramine on intracranial self-stimulation in rats were studied with electrodes in the A10 region of the dopamine-containing cell bodies of the ventromedial tegmentum. Long-term desipramine administration resulted in a significant shift to the left in the ascending portion of the rate--current intensity function, indicating that the activity of the mesolimbic dopamine system was enhanced. These findings point to a possible dopaminergic mechanism of action of antidepressants and support speculations concerning the role of dopamine-containing neurons in the pathophysiology of depression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fibiger, H C -- Phillips, A G -- New York, N.Y. -- Science. 1981 Nov 6;214(4521):683-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7197394" target="_blank"〉PubMed〈/a〉

    Description: Human malignant cancer tumors grafted into nude mice produce tumors containing both human cancer cells and the host's stromal cells. After short-term propagation of these tumors in vitro, the murine mesenchymal cells appear transformed and are tumorigenic in nude mice. However, established human cancer cell lines fail to similarly after adjacent murine stromal cells when used to produce tumors in nude mice. These experiments suggest that cancer cells may recruit normal cells to become malignant, qualifying the view of the clonal (unicellular) origin of cancer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goldenberg, D M -- Pavia, R A -- 1R01 CA17198/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1981 Apr 3;212(4490):65-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7209521" target="_blank"〉PubMed〈/a〉

    Description: Voltage clamp studies of macrophages from cultures of mouse spleen macrophages produced N-shaped steady-state current-voltage curves containing a region of negative slope resistance. Some macrophages exhibit two stable states of membrane potential, having current-voltage relationships that cross the voltage axis at three points. Outward currents that turn on at voltages of +15 millivolts or greater were noted in several cells. The addition of barium chloride to the bathing medium abolished the negative slope resistance and reduced the inward currents in response to hyperpolarizing voltage steps. These data provide direct evidence that macrophages exhibit at least tow different voltage-dependent conductances and demonstrate that voltage clamp techniques can be useful in studying the membrane properties of leukocytes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gallin, E K -- New York, N.Y. -- Science. 1981 Oct 23;214(4519):458-60.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7291986" target="_blank"〉PubMed〈/a〉

    Description: Incubation at 37 degrees C of excised rat prostate tissue results in massive proliferative assembly of new tight junction strands along the entire lengths of the lateral plasma membranes of the columnar epithelial cells. The new tight junction elements are assembled within 5 minutes and have an average length six times that of those present in the apical tight junction band. Massive assembly occurs in the presence of protein synthesis inhibitors (cycloheximide) or of metabolic uncouplers (dinitrophenol). Thus, proliferative assembly of tight junction strands involves molecular reorganization from a pool of preexisting, probably membrane-associated, components. The fascia occludens and some examples of experimentally induced tight junction proliferation may reflect the massive emergence of tight junction strands when tissue is subjected to diverse stressful conditions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kachar, B -- Pinto da Silva, P -- New York, N.Y. -- Science. 1981 Jul 31;213(4507):541-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7244652" target="_blank"〉PubMed〈/a〉

    Description: Ovaries removed from New Zealand White rabbits were perfused and exposed to gonadotropin in vitro. The ova ovulated in vitro (N = 56) were recovered and cultured and then transferred to the oviducts of six previously mated Dutch Belted hosts. Twelve of the resulting 36 offspring (33.3 percent) were white. In control matings between 12 Dutch Belted females (six randomly selected and the six hosts) and New Zealand White males, only one of 80 (1.2 percent) offspring was white. These data indicate that ova ovulated in vitro can be transferred to the oviduct of a host rabbit where they may be fertilized and after implantation may develop into viable embryos.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kobayashi, Y -- Santulli, R -- Wright, K H -- Wallach, E E -- HD-05948/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1981 Sep 4;213(4512):1127-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7268420" target="_blank"〉PubMed〈/a〉

    Description: The addition of ethanol or other aliphatic alcohols to rat brain membranes strongly inhibits binding of enkephalins at concentrations at which little inhibition of opiate alkaloids is seen. Inhibition is reversible, and potency increases with chain length of the alcohol. The results suggest that delta receptors are considerably more sensitive to alcohols than mu receptors. This is the first demonstration of selective inhibition of one of the postulated classes of opiate receptors by a reagent that is not a ligand for the receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hiller, J M -- Angel, L M -- Simon, E J -- DA-00017/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 1981 Oct 23;214(4519):468-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6270788" target="_blank"〉PubMed〈/a〉

    Description: Human keratinocytes, derived from the skin of newborns and of adults, were grown in the complete absence of serum, in a hormone-supplemented medium on fibronectin-coated cell culture dishes at low seed density. The cell culture medium consisted of Medium 199 containing epidermal growth factor, triiodothyronine, hydrocortisone, Cohn fraction IV, insulin, transferrin, bovine brain extract, and trace elements. Removal of the brain extract from the hormone supplement had a greater negative impact on proliferation of the keratinocyte cultures than did the removal of epidermal growth factor, hydrocortisone, and triiodothyronine or Cohn fraction IV. The growth of keratinocytes in this hormone-supplemented medium suggests that control of keratinocyte growth depends in large part on endocrine stimulation by other body organs, including the brain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maciag, T -- Nemore, R E -- Weinstein, R -- Gilchrest, B A -- AG 0599/AG/NIA NIH HHS/ -- HO 07374/HO/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1981 Mar 27;211(4489):1452-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6970413" target="_blank"〉PubMed〈/a〉

    Description: Two divalent cation ionophores, A23187 and Ionomycin, which are selective for calcium, stimulated the resorption of fetal rat long bones in organ culture at 0.1 to 1 micromolar but not at higher concentrations. Both agents inhibited DNA synthesis at concentrations that stimulated resorption. These results might explain the differences in ionophore effects on bone previously reported, and they imply that cell replication is not required for osteoclast formation in fetal rat long bone cultures.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lorenzo, J A -- Raisz, L G -- AM 07290/AM/NIADDK NIH HHS/ -- AM 18063/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1981 Jun 5;212(4499):1157-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6785885" target="_blank"〉PubMed〈/a〉

    Description: Field potentials and extracellular potassium concentration ([K+]o) were simultaneously monitored in the molecular layer of the rat cerebellar cortex during stimulation of the parallel fibers. The synaptic field potential elicited by stimulation was reduced by several methods. Reduction of synaptic field potentials was accompanied by a marked increase in the excitability of the parallel fibers. This change in excitability was related to the degree of extracellular K+ accumulation associated with parallel fiber stimulation. These findings support the proposal that increases in [K+]o associated with activity in postsynaptic elements can modulate the excitability of presynaptic afferent fibers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Malenka, R C -- Kocsis, J D -- Ransom, B R -- Waxman, S G -- NS 15589/NS/NINDS NIH HHS/ -- NS-00473/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1981 Oct 16;214(4518):339-41.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7280695" target="_blank"〉PubMed〈/a〉

    Description: Ten patients with multiple sclerosis who were treated with human fibroblast interferon (IFN-B) for 6 months showed a significant reduction in their exacerbation rates compared with their rates before treatment (P 〈 .01). The IFN-B was administered intrathecally by serial lumbar punctures. There was no significant change in the exacerbation rates of ten multiple sclerosis control patients before and during the period of observation. The IFN-B recipients have now been on the study a mean of 1.5 years, the controls, 1.2 years. The clinical condition of five of the IFN-B recipients and one of the control patients has improved, whereas the condition of five of the controls and one of the IFN-B recipients has deteriorated (P 〈 .036). These findings warrant cautious optimism about the efficacy of intrathecal IFN-B in altering the course of multiple sclerosis and support concepts of a viral or dysimmune etiology of the disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jacobs, L -- O'Malley, J -- Freeman, A -- Ekes, R -- CA-18533/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1981 Nov 27;214(4524):1026-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6171035" target="_blank"〉PubMed〈/a〉

Rates of liver cancer, lymphoma, and leukemia, which were selected for special attention, were not consistently elevated. Among the other cancers studied, a higher rate was noted only for respiratory cancer, but it was not consistent across age groups and appeared to be related to a high rate for the entire city of Niagara Falls. There was no evidence that the lung cancer rate was associated with the toxic wastes buried at the dump site.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Janerich, D T -- Burnett, W S -- Feck, G -- Hoff, M -- Nasca, P -- Polednak, A P -- Greenwald, P -- Vianna, N -- New York, N.Y. -- Science. 1981 Jun 19;212(4501):1404-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7233229" target="_blank"〉PubMed〈/a〉

    Description: A single application of electroconvulsive shock produced a rapid but short-lasting increase in tyrosine hydroxylase activity above control values in the rat adrenal medulla and striatum. After repeated electroconvulsive shock treatment (once per day for 7 days), tyrosine hydroxylase activity increased significantly in the locus ceruleus, nucleus of the tractus solitarius, hippocampus, cerebellum, and frontal cortex and remained elevated for 4 to 8 days. Adrenal tyrosine hydroxylase activity increased 1 day after the termination of repeated electroconvulsive shock treatments and remained elevated for at least 24 days, possibly reflecting the establishment of a new and higher steady-state level of catecholamine biosynthesis in the adrenal. These findings suggest that the persistent changes in tyrosine hydroxylase activity produced by repeated electroconvulsive shock may be a factor contributing to the long-lasting antidepressant effects of this treatment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Masserano, J M -- Takimoto, G S -- Weiner, N -- NS 07927/NS/NINDS NIH HHS/ -- NS 09199/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1981 Nov 6;214(4521):662-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6117127" target="_blank"〉PubMed〈/a〉

    Description: In vitamin D-deficient rats intestinal calcium transport increased significantly 4 hours after an injection of prolactin, reached a maximum after 8 hours, and declined to preinjection levels after 24 hours. Similarly, in vitamin D-deficient rats fed a diet low in calcium or phosphorus prolactin stimulated an increase in serum calcium in both groups and an increase in serum phosphorus in the rats fed the diet low in phosphorus. Thus it appears that prolactin affects organs involved in calcium regulation in a manner that is independent of the vitamin D endocrine system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pahuja, D N -- DeLuca, H F -- AM-14881/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1981 Nov 27;214(4524):1038-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7302575" target="_blank"〉PubMed〈/a〉

In many seminiferous tubules, nuclei of spermatogonial cells were also immunopositive. Both cytoplasmic and nuclear fractions of testicular homogenates contain immunoreactive compounds, and this report identifies which cell types contain this substance.

    Description: The contributions of the inner and outer hair cells of the mammalian cochlea to auditory intensity discrimination were evaluated in a combined behavioral-anatomical study of the guinea pig. Intensity difference thresholds were unchanged from baseline values after selective destruction of outer hair cells, suggesting that those cells are unnecessary for normal intensity discrimination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Prosen, C A -- Moody, D B -- Stebbins, W C -- Hawkins, J E Jr -- NS 05065/NS/NINDS NIH HHS/ -- NS 05785/NS/NINDS NIH HHS/ -- NS 15108/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1981 Jun 12;212(4500):1286-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7233219" target="_blank"〉PubMed〈/a〉

    Description: Mice fed a purified diet low in copper display anemia, hypoceruloplasminemia, depressed concentrations of liver copper, and elevated concentrations of liver iron. An impaired humoral-mediated immune response (decreased numbers of antibody-producing cells) is observed in mice with severe as well as marginal copper deficiency. The magnitude of this impairment is highly correlated with the degree of functional copper deficiency (hypoceruloplasminemia).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Prohaska, J R -- Lukasewycz, O A -- New York, N.Y. -- Science. 1981 Jul 31;213(4507):559-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7244654" target="_blank"〉PubMed〈/a〉

    Description: The effects of amitriptyline, lithium, and electroconvulsive shock on cerebral permeability and blood flow were tested. These three treatments share in common (i) the ability to influence the functional activity of central adrenergic neurons by way of effects on the release, reuptake, or metabolism of norepinephrine and (ii) therapeutic efficacy in mood disturbances. Under control conditions, cerebral permeability increases linealy with increasing arterial partial pressure of carbon dioxide and hence cerebral blood flow. All three treatments altered this relationship in a manner consistent with their adrenergic effects. Amitriptyline potentiated this increase in cerebral permeability whereas lithium and electroconvulsive shock blunted this phenomenon. These results support the hypothesis that one function of central adrenergic neurons is regulation of the blood-brain barrier and raise the possibility that a related effect may underlie the clinical usefulness of such treatment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Preskorn, S H -- Irwin, G H -- Simpson, S -- Friesen, D -- Rinne, J -- Jerkovich, G -- GM15956/GM/NIGMS NIH HHS/ -- MH-00272/MH/NIMH NIH HHS/ -- NS17252/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1981 Jul 24;213(4506):469-71.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7244645" target="_blank"〉PubMed〈/a〉

    Description: A vitamin D--dependent calcium binding protein in the chick kidney that was detected by immunocytochemical techniques was localized exclusively in the distal convoluted tubule, the initial collecting tubule, and the early part of the collecting tubule. The intercalated (mitochondria-rich) cells in these tubular segments were negative for the calcium binding protein. Subcellularly, the protein was found in the cytosol and the nucleus of the tubular cells. The results suggest a role for vitamin D--dependent calcium binding protein in intracellular calcium metabolism rather than a direct involvement in membrane-mediated calcium reabsorption in the avian kidney.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roth, J -- Thorens, B -- Hunziker, W -- Norman, A W -- Orci, L -- AM-09012/AM/NIADDK NIH HHS/ -- AM-14, 750/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1981 Oct 9;214(4517):197-200.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7025212" target="_blank"〉PubMed〈/a〉

    Description: The kinetic patterns of DNA synthesis in wild-type (RAD+) and rad 52 mutants of yeast, which exhibit high levels of synchrony during meiosis, are comparable. However, RAD 52 mutants accumulate single-strand breaks in parental DNA during the DNA synthesis period. Thus, the product of the RAD 52 gene has a role in meiotic DNA metabolism, as well as in the repair of DNA damage during mitotic growth. The observed breaks may be unresolved recombination intermediates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Resnick, M A -- Kasimos, J N -- Game, J C -- Braun, R J -- Roth, R M -- 5 R01 GM17317-11/GM/NIGMS NIH HHS/ -- S07-RR07027/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1981 May 1;212(4494):543-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7010606" target="_blank"〉PubMed〈/a〉

    Description: The binding of [3H]diazepam to benzodiazepine receptors was studied in extensively washed membranes of rat cerebral cortex in the presence of the depressant barbiturate, pentobarbital. Pentobarbital, like the endogenous neurotransmitter gamma-aminobutyric acid (GABA), increased the basal binding and also potentiated the GABA-enhanced binding of [3H]diazepam to benzodiazepine receptors by increasing the apparent affinity of [3H]diazepam for the benzodiazepine receptor. The concentrations of pentobarbital necessary to elicit these effects in vitro are the same as those observed after treatment with pharmacologically relevant doses, suggesting that a common neurochemical association may exist between these types of compounds.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Skolnick, P -- Moncada, V -- Barker, J L -- Paul, S M -- New York, N.Y. -- Science. 1981 Mar 27;211(4489):1448-50.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6258230" target="_blank"〉PubMed〈/a〉

    Description: Viruses classified by immunologic criteria as equine herpesvirus 1 cause respiratory disease and abortion in horses. Restriction endonuclease analyses of the DNA's of viruses from animals with respiratory disease and from aborted fetuses show that the patterns for respiratory viruses, while similar to each other, are entirely different from the patterns for fetal viruses. It is therefore proposed that the DNA restriction endonuclease patterns of fetal and respiratory viruses analyzed in this study be designated as prototypic of equine herpesvirus 1 and 4, respectively.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Studdert, M J -- Simpson, T -- Roizman, B -- CA 08494/CA/NCI NIH HHS/ -- CA 09241/CA/NCI NIH HHS/ -- CA 19264/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1981 Oct 30;214(4520):562-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6270790" target="_blank"〉PubMed〈/a〉

    Description: Vitellogenin is synthesized under estrogen control in the liver, extensively modified, transported to the ovary, and there processed to the yolk proteins lipovitellin and phosvitin. In the frog Xenopus laevis there are at least four distinct but related vitellogenin genes. The two genes A1 and A2 have a 95 percent sequence homology in their messenger RNA coding regions, and contain 33 introns that interrupt the coding region (exons) at homologous positions. Sequences and lengths of analogous introns differ, and many introns contain repetitive DNA elements. The introns in these two genes that have apparently arisen by duplication have diverged extensively by events that include deletions, insertions, and probably duplications. Rapid evolutionary change involving rearrangements and the presence of repeated DNA suggests that the bulk of the sequences within introns may not have any specific function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wahli, W -- Dawid, I B -- Ryffel, G U -- Weber, R -- New York, N.Y. -- Science. 1981 Apr 17;212(4492):298-304.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7209528" target="_blank"〉PubMed〈/a〉

Cognitively unimpaired, as well as cognitively impaired adults, treated with DDAVP for a period of several days, learn information more effectively, as measured by the completeness, organization, and consistency (reliability) of recall.

The C3 deficiency appears to be transmitted as an autosomal recessive trait.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Winkelstein, J A -- Cork, L C -- Griffin, D E -- Griffin, J W -- Adams, R J -- Price, D L -- AI-11637/AI/NIAID NIH HHS/ -- NS-10580/NS/NINDS NIH HHS/ -- RR-00130/RR/NCRR NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1981 Jun 5;212(4499):1169-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7233211" target="_blank"〉PubMed〈/a〉

    Description: The low activity of liver neuraminidase that is characteristic of mouse strain SM/J is inherited as a single gene on chromosome 17, near the major histocompatibility complex. This gene, neuraminidase-1 (Neu-1), is represented by the low activity allele Neu-1s in SM/J and the high activity allele Neu-1b in C57BL/6J and most other strains. Previously described variations in the posttranslational processing of acid phosphatase, alpha-mannosidase, arylsulfatase-B, and alpha-glucosidase are attributed to pleiotropic effects of this gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Womack, J E -- Yan, D L -- Potier, M -- New York, N.Y. -- Science. 1981 Apr 3;212(4490):63-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7209520" target="_blank"〉PubMed〈/a〉

    Description: The cumulative effects of a repetitive stress induced by anticipation of pain (noxious foot shock) were studied on the threshold of a nociceptive flexion reflex of the lower limb. The threshold of the nociceptive reflex progressively increased with the repetition of the stress. This effect was reversed by naloxone, which even produced hyperalgesia, since a rapid and significant decrease in this threshold, below the initial values, was noted. Tha data provide evidence for involvement of endogenous opioids in the phenomenon of stress-induced analgesia in normal man.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Willer, J C -- Dehen, H -- Cambier, J -- New York, N.Y. -- Science. 1981 May 8;212(4495):689-91.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6261330" target="_blank"〉PubMed〈/a〉

    Description: Rat pups nursed by pregnant dams grow as fast as pups reared by dams that are not pregnant. Moreover, litters that were in utero during a lactation are as numerous at birth and grow as fast as pups developing in a nonlactating, pregnant mother. These litters continue to grow as fast as pups born to nonlactating dams whether or not the first litter remains after the birth of the second litter. When pregnant and lactating dams have a restricted food supply, some dams are capable of extending the duration of their pregnancies by over 2 weeks past that of nonlactating, pregnant dams. This facultative prolongation of pregnancy apparently allows females to carry normal litters to term.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Woodside, B -- Wilson, R -- Chee, P -- Leon, M -- New York, N.Y. -- Science. 1981 Jan 2;211(4477):76-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7444451" target="_blank"〉PubMed〈/a〉

At birth, offspring were placed with untreated surrogate dams. Beginning at 6 months of age, the offspring were tested for their thermogenic responsiveness to various drugs and to cold. Prenatal exposure to alcohol resulted in tolerance to alcohol and cross-tolerance to pentobarbital and diazepam but did not affect responsiveness to cold. This pattern of effects suggest that prenatal exposure to alcohol produces specific long-term effects on the neural mechanisms underlying drug tolerance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Abel, E L -- Bush, R -- Dintcheff, B A -- New York, N.Y. -- Science. 1981 Jun 26;212(4502):1531-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7233243" target="_blank"〉PubMed〈/a〉

    Description: Phencyclidine (PCP), lysergic acid diethylamide (LSD), and mescaline produced potent contractile responses on isolated basilar and middle cerebral arteries, where, in terms of potency, LSD greater than mescaline greater than PCP. All three drugs produced cerebrovasospasm in a concentration range which parallels that needed for their psychotomimetic and intoxicating actions. Specific receptors for PCP, which subserve contraction and differ from those for LSD and mescaline, are found in cerebral arteries. Concentrations of PCP that produced near-maximum contractile responses on cerebral arteries were similar to those in the blood and brain of human subjects who had died from PCP overdoses. A specific calcium antagonist, verapamil, readily prevented (and reversed) PCP-induced vasospasm. This study provides direct evidence for PCP receptors in cerebral blood vessels, the biologic action of which can be reversed by a calcium antagonist; the clinical use of the latter could prove invaluable in treating PCP-intoxicated victims.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Altura, B T -- Altura, B M -- DA 02339/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 1981 May 29;212(4498):1051-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7195070" target="_blank"〉PubMed〈/a〉

Once converted, the 3T3-L1 fat cells retained their adipose morphology and accumulated triglycerides even when 3-deazaadenosine was removed from the culture medium. 3-Deazaadenosine may perturb cellular methylation and thereby lead to an increase in the frequency of differentiation of 3T3-L1 fibroblasts to fat cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chiang, P K -- New York, N.Y. -- Science. 1981 Mar 13;211(4487):1164-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7466386" target="_blank"〉PubMed〈/a〉

    Description: Female prairie voles (Microtus ochrogaster) exposed to a single drop of male urine on the upper lip showed changes in concentrations of luteinizing hormone-releasing hormone (LHRH) and norepinephrine in olfactory bulb tissue; no such changes occurred in dopamine concentration. The changes were measured in the posterior but not the anterior olfactory bulb tissue of females within 1 hour after they were exposed to urine. These females also showed rapid increases in serum concentrations of luteinizing hormone. Females exposed to water on the upper lip showed none of these changes. These results suggest that in this species LHRH and norepinephrine in the olfactory bulb may mediate luteinizing hormone release in response to external (pheromonal) chemical cues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dluzen, D E -- Ramirez, V D -- Carter, C S -- Getz, L L -- HDO9328/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1981 May 1;212(4494):573-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7010608" target="_blank"〉PubMed〈/a〉

    Description: Oral administration of delta 9-tetrahydrocannabinol had a biphasic effect on plasma testosterone concentrations in male mice, causing rapid sustained increases at low doses and subsequent decreases at higher doses. In hypophysectomized and intact mice receiving gonadotropins (human chorionic gonadotropin), treatment with delta 9-tetrahydrocannabinol maintained higher plasma testosterone concentrations. Thus, this cannabinoid may interact with gonadotropin and directly influence testicular steroidogenesis in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dalterio, S -- Bartke, A -- Mayfield, D -- 1R01 DA 02/DA/NIDA NIH HHS/ -- P 30 HD 10202/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1981 Jul 31;213(4507):581-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6264607" target="_blank"〉PubMed〈/a〉

    Description: The role of brain cholecystokinin peptides in satiety was further assessed by using antibody to cholecystokinin to reduce cholecystokinin activity in the cerebrospinal fluid of sheep. Food intakes were increased approximately 100 percent during the 2-hour continuous injection of antibody into the cerebrospinal fluid. This supports the hypothesis that, during feeding, cholecystokinin is released into the cerebrospinal fluid, which transports it to the receptors that elicit satiety.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Della-Fera, M A -- Baile, C A -- Schneider, B S -- Grinker, J A -- GM 02051/GM/NIGMS NIH HHS/ -- NS 06595/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1981 May 8;212(4495):687-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7221559" target="_blank"〉PubMed〈/a〉

    Description: A covalent conjugate of an alpha-amanitin azo derivative and a monoclonal immunoglobulin G to the Thy 1.2 antigen on murine T lymphocytes was synthesized. The conjugate was 375- to 750-fold more inhibitory to murine T lymphoma S49.1 cells than the unconjugated derivative. At 0.7 X 10(-7) to 1.5 X 10(-7) M and at 4 X 10(-7) M amanitin equivalents, the conjugate inhibited protein synthesis in S49.1 cells by 50 percent and 80 to 96 percent, respectively. At these concentrations, mutant Thy l-deficient S49 cells and other murine lymphoma lacking Thy l altogether or carrying Thy 1.1 antigens were unaffected. This result demonstrated the potential for targeting amanitin to specific cell types.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, M T -- Preston, J F 3rd -- R01 CA 19043/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1981 Sep 18;213(4514):1385-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6115471" target="_blank"〉PubMed〈/a〉

    Description: When bound to cell surfaces, certain lectins such as concanavalin A induce a drop in the average diffusion coefficients (D) of a number of cell surface molecules. To find whether such anchorage modulation occurs naturally, D of surface antigens on different cell and tissue types were measured by fluorescence photobleaching recovery. Values for cells of the same tissue origin under different conditions of growth and association - in tissues, in small aggregates, and as isolated cells - varied by less than twofold when polyspecific monovalent antibodies to cell surface antigens were used, a range much less than the sixfold decrease in D observed after lectin-induced anchorage modulation. Thus, if reversible modulation of the diffusion rate is used naturally as a means of cell signaling, it must involve only a few kinds of surface receptors not detected by the antibodies used in this study. In certain tissues, however, a significant proportion of cells showed no apparent receptor mobility. This "all or none" modulation of lateral diffusion may reflect relatively long-lasting alterations in the states of a single cell type or differentiation among the cells of the particular tissue.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gall, W E -- Edelman, G M -- AI-09273/AI/NIAID NIH HHS/ -- AI-11378/AI/NIAID NIH HHS/ -- AM-04256/AM/NIADDK NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1981 Aug 21;213(4510):903-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7196087" target="_blank"〉PubMed〈/a〉

    Description: The 2-[18F]fluoro-2-deoxy-D-glucose technique was used to measure regional cerebral glucose utilization by human subjects during functional activation. Normal male volunteers subjected to one or more sensory stimuli (tactile, visual, or auditory) exhibited focal increases in glucose metabolism in response to the stimulus. Unilateral visual hemifield stimulation caused the contralateral striate cortex to become more metabolically active than the striate cortex ipsilateral to the stimulated hemifield. Similarly, stroking the fingers and hand of one arm with brush produced an increase in metabolism in the contralateral postcentral gyrus, compared with the homologous ipsilateral region. The auditory stimulus, which consisted of a monaurally presented factual story caused an increase in glucose metabolism in the auditory cortex in the hemisphere contralateral to the stimulated ear. These results demonstrate that the technique is capable of providing functional maps in vivo related to both body region and submodality of sensory information in the human brain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Greenberg, J H -- Reivich, M -- Alavi, A -- Hand, P -- Rosenquist, A -- Rintelmann, W -- Stein, A -- Tusa, R -- Dann, R -- Christman, D -- Fowler, J -- MacGregor, B -- Wolf, A -- NS 10939-08/NS/NINDS NIH HHS/ -- NS 14867-02/NS/NINDS NIH HHS/ -- NS 15380-04/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1981 May 8;212(4495):678-80.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6971492" target="_blank"〉PubMed〈/a〉

This effect is prevented by shielding the occiput, by inhibiting corticosterone synthesis, and by exogenous melatonin. Furthermore, the expected hypocalcemic response to cortisol injection is prevented by melatonin. Light-induced hypocalcemia may result from increased calcium uptake by bone when the blocking effect of melatonin decreases after pineal inhibition by transcranial illumination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hakanson, D O -- Bergstrom, W H -- New York, N.Y. -- Science. 1981 Nov 13;214(4522):807-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6895262" target="_blank"〉PubMed〈/a〉

The main determinant of gonadal differentiation appears to be the presence or absence of a cell surface antigen, called H-Y antigen. The regulation of H-Y antigen expression is complex and involves the interaction between regulatory sites on the Y chromosome, the X chromosome, and possibly the autosomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Haseltine, F P -- Ohno, S -- 5R01 HD 12289-02/HD/NICHD NIH HHS/ -- R0I AD 00042/AD/ADAMHA HHS/ -- New York, N.Y. -- Science. 1981 Mar 20;211(4488):1272-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7010601" target="_blank"〉PubMed〈/a〉

    Description: Kirsten sarcoma virus produced a low incidence of transient morphological transformation in primary cultures of rat ovarian granulosa cells. In the presence of epidermal growth factor, the incidence of transient transformation increased severalfold and two continuous cell lines were established. Epidermal growth factor, a naturally occurring polypeptide hormone, appears to act here as a tumor promoter in the retrovirus-induced transformation of a mesodermally derived epithelium.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Harrison, J -- Auersperg, N -- New York, N.Y. -- Science. 1981 Jul 10;213(4504):218-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6264597" target="_blank"〉PubMed〈/a〉

    Description: The mitogenic effect of somatomedin B on human cultured glial cells was neutralized by the addition of antibodies to mouse epidermal growth factor. Somatomedin B contained epidermal growth factor--like activity, competing for binding to the epidermal growth factor receptor. It is concluded that contaminating epidermal growth factor may explain the entire mitogenic activity of somatomedin B.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Heldin, C H -- Wasteson, A -- Fryklund, L -- Westermark, B -- New York, N.Y. -- Science. 1981 Sep 4;213(4512):1122-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6973821" target="_blank"〉PubMed〈/a〉

    Description: The content of tetrahydrobiopterin in rat brain was doubled by peripherally administered tetrahydrobiopterin, with the natural 1 diastereoisomer more effective than the unnatural d configuration. The model pteridine, 6-methyltetrahydropterin was ten times more efficient than tetrahydrobiopterin in crossing the blood-brain barrier, and striatal concentrations of 6-methyltetrahydropterin remained elevated for 2 hours, declining with a half-life of 3 hours. While no evidence for a specific uptake mechanism for concentrating 6-methyltetrahydropterin in cells containing tetrahydrobiopterin was detected, the pterin was found in ts presumed site of action, the nerve terminal. Replacement therapy with reduced pterins may therefore be effective in the treatment of the neurological disorders associated with the variant forms of hyperphenylalaninemia that result from defects in the biosynthesis or metabolism of tetrahydrobiopterin within the central nervous system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kapatos, G -- Kaufman, S -- New York, N.Y. -- Science. 1981 May 22;212(4497):955-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7233193" target="_blank"〉PubMed〈/a〉

    Description: Metronidazole is a drug used for the treatment of trichomonal vaginitis, amebiasis, giardiasis, and certain anaerobic bacterial infections in humans. Acetamide and N-(2-hydroxyethyl)oxamic acid are metabolites of metronidazole in the rat, and we find small amounts of both metabolites in the urine of human patients taking the drug. Although acetamide is carcinogenic for rats, we do not believe that our finding further defines metronidazole's risk for humans. That risk can only be estimated from surveillance of people previously exposed to the drug.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kock, R L -- Beaulieu, B B Jr -- Chrystal, E J -- Goldman, P -- R01-CA1520/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1981 Jan 23;211(4480):398-400.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7221546" target="_blank"〉PubMed〈/a〉
