    Sex pheromone of the tsetse fly: isolation, identification, and synthesis of contact aphrodisiacs (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-08-25
    Description: Sex pheromones isolated from the cuticle of the female tsetse fly, Glossina morsitans morsitans Westwood, release mating behavior in the male fly at ultrashort range or upon contact with baited decoys. Three active components were identified as 15,19-dimethylheptatriacontane, 17,21-dimethylheptatriacontane, and 15,19,23-trimethylheptatriacontane. Chemical and biological comparisons show that the natural and synthetic compounds are identical.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carlson, D A -- Langley, P A -- Huyton, P -- New York, N.Y. -- Science. 1978 Aug 25;201(4357):750-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/675256" target="_blank"〉PubMed〈/a〉

    Guanosine 3',5'-monophosphate: a central nervous system regulator of analgesia (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-01-20
    Description: The dibutyryl derivative of guanosine 3',5'-monophosphate (cyclic GMP), administered centrally, totally abolishes response to noxious stimuli without depressing the central nervous system. Analgesic properties of the nucleotide are not reversed by naloxone. Microinjected intracerebrally into different sites, dibutyryl cyclic GMP does not mimic the action of morphine. Pharmacological effects of dibutyryl cyclic GMP suggest that endogenous cyclic GMP modulates an inhibitory pain pathway distinct from that on which morphine acts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cohn, M L -- Cohn, M -- Taylor, P H -- New York, N.Y. -- Science. 1978 Jan 20;199(4326):319-22.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/202029" target="_blank"〉PubMed〈/a〉

    Dual actions of substance P on nociception: possible role of endogenous opioids (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-03-24
    Description: Substance P produces analgesia when administered to mice in very small doses by the intraventricular route (1.25 to 5 nanograms per mouse). The analgesic effect can be blocked by naloxone. At higher doses (greater than 50 nanograms per mouse), this activity is lost. At these higher doses, however, substance P produced hyperalgesia when combined with naloxone and analgesia when combined with baclofen [beta-(4-chlorophenyl)-gamma-aminobutyric acid]. Substance P may have dual actions in brain, releasing endorphins at very low doses and directly exciting neuronal activity in nociceptive pathways at higher doses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Frederickson, R C -- Burgis, V -- Harrell, C E -- Edwards, J D -- New York, N.Y. -- Science. 1978 Mar 24;199(4335):1359-62.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/204012" target="_blank"〉PubMed〈/a〉

    Diazepam inhibits myoblast fusion and expression of muscle specific protein synthesis (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-05-05
    Description: The presence of diazepam in culutres of chicken embryo myoblasts arrests normal muscle cell differentiation. High concentrations of the drug reversibly prevent myoblasts from fusing to form multinucleated myotubes. Lower concentrations of diazepam allow cell fusion to occur, but inhibit the synthesis and accumulation of myosin heavy chain, implying that cell fusion does not obligate myoblasts to synthesize and accumulate large quantities of muscle specific protein. The effect of diazepam on muscle cells in culture is direct and specific.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bandman, E -- Walker, C R -- Strohman, R C -- New York, N.Y. -- Science. 1978 May 5;200(4341):559-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/565534" target="_blank"〉PubMed〈/a〉

    Hypophysial responses to continuous and intermittent delivery of hypopthalamic gonadotropin-releasing hormone (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-11-10
    Description: In rhesus monkeys with hypothalamic lesions that abolish gonadotropic hormone release by the pituitary gland, the constant infusion of exogenous gonadotropin-releasing hormone (GnRH) fails to restore sustained gonadotropin secretion. In marked contrast, intermittent administration of the synthetic decapeptide once per hour, the physiological frequency of gonadotropin release in the monkeys, reestablishes pituitary gonadotropin secretion. This phenomenon is attributable to the pattern of GnRH delivery rather than to the amounts of this hormone to which the cells of the pituitary are exposed. Moreover, the initiation of continuous GnRH administration in animals with lesions and in which gonadotropin secretion is reestablished by intermittent GnRH replacement can result in a "desensitization" or "down regulation" of the processes responsible for gonadotropin release.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Belchetz, P E -- Plant, T M -- Nakai, Y -- Keogh, E J -- Knobil, E -- New York, N.Y. -- Science. 1978 Nov 10;202(4368):631-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/100883" target="_blank"〉PubMed〈/a〉

    Description: Nineteen epileptic patients were tested first under medium (week 1) and then under high (week 2) therapeutic levels of phenobarbital. Relative to response times of 20 controls with equivalent practice but without medication, response times of patients in a short-term memory scanning task were strikingly slowed during week 2. However, increased phenobarbital did not slow responses in a task requiring access to information in long-term memory.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉MacLeod, C M -- Dekabian, A S -- Hunt, E -- New York, N.Y. -- Science. 1978 Dec 8;202(4372):1102-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/715461" target="_blank"〉PubMed〈/a〉

    Specific-opiate-induced depression of transmitter release from dorsal root ganglion cells in culture (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-03-31
    Description: The opiate etorphine depresses monosynaptic excitatory postsynaptic potentials (EPSP's) elicited in spinal cord cells by activation of dorsal root ganglion cells in murine neuronal cell culture. The depression is reversed by naloxone. Statistical analysis of the synaptic responses reveals that the opiate reduces EPSP quantal content at this synapse without altering quantal size. Therefore, the opiate action is presynaptic and affects transmitter release rather than postsynaptic responsiveness.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Macdonald, R L -- Nelson, P G -- New York, N.Y. -- Science. 1978 Mar 31;199(4336):1449-51.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/204015" target="_blank"〉PubMed〈/a〉

Only inhibition of enzyme activity was observed. Concentrations of ouabain used ranged from 3.3 x 10(-10) molar to 5 x 10(-7) molar and produced an increased force of contraction without any evidence of toxicity.

    Description: Endogenous opiate-like peptides (endorphins) are putative neuroregulators located throughout the mammalian brainstem. There is some evidence for their role in pain, stress, and affect. We report that the opiate antagonist, naloxone, alters some schizophrenic symptoms. In a double-blind, cross-over study, naloxone produced decreases in auditory hallucinations in some schizophrenic patients. This finding supports the hypothesis that the endorphins may play a roll in modulating hallucinations in a highly selected subgroup of chronically hallucinating schizophrenic patients.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Watson, S J -- Berger, P A -- Akil, H -- Mills, M J -- Barchas, J D -- New York, N.Y. -- Science. 1978 Jul 7;201(4350):73-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/351804" target="_blank"〉PubMed〈/a〉

The ionophores X537A and A23187 accentuated the effect of a low dose of calcium, whereas the calcium chelators EDTA and EGTA decreased sleeping time. Calcium also enhanced tertiary butanol- and chloral hydrate-induced sleeping time. The effects of cations on ethanol-induced hypothermia were less significant. The results suggest the existence of a central calcium pool that is involved in ethanol intoxication in rodents.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Erickson, C K -- Tyler, T D -- Harris, R A -- New York, N.Y. -- Science. 1978 Mar 17;199(4334):1219-21.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/343251" target="_blank"〉PubMed〈/a〉

    Different brain areas mediate the analgesic and epileptic properties of enkephalin (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-04-21
    Description: Single injections of 120 micrograms of methionine-enkephalin were made into various midbrain and forebrain structures in the rat. Analgesia was observed after injections into or near the ventral, caudal midbrain periaqueductal gray matter. Seizures and other pathological electroencephalogram (EEG) changes were seen with injections into or near the forebrain dorsomedial nucleus of the thalamus. No animals with midbrain injection sites showed EEG changes, and none with forebrain injection sites were analgesic. These data, taken together with other lines of evidence, suggest that enkephalin-induced analgesia and enkephalin-induced seizures are mediated by opiate receptors that are located in different brain areas and that are pharmacologically different.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Frenk, H -- McCarty, B C -- Liebeskind, J C -- New York, N.Y. -- Science. 1978 Apr 21;200(4339):335-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/204998" target="_blank"〉PubMed〈/a〉

    Kainic acid injections result in degeneration of cochlear nucleus cells innervated by the auditory nerve (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-12-08
    Description: When kainic acid, a putative neurotoxin for neurons with glutamatergic input, is injected into the brainstem, it produces a selective pattern of degeneration in the cochlear nucleus. The rate and extent of degeneration is correlated with the distribution of the primary auditory fibers. This evidence supports the hypothesis that glutamate is the neurotransmitter for primary auditory fibers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bird, S J -- Gulley, R L -- Wenthold, R J -- Fex, J -- New York, N.Y. -- Science. 1978 Dec 8;202(4372):1087-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/31000" target="_blank"〉PubMed〈/a〉

    Cholecystokinin inhibits tail pinch-induced eating in rats (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-05-19
    Description: Peripheral administration of the COOH-terminal octapeptide of cholecystokinin in doses from 1 to 100 micrograms per kilogram of body weight (0.25 to 25.0 micrograms per rat) significantly antagonized tail pinch-induced eating in rats, an animal model for stress-induced human hyperphagia. Centrally administered cholecystokinin was effective only in high doses (3 micrograms into the cerebral ventricle). The finding that the minimal effective dose of cholecystokinin in suppressing stress-induced appetitive behavior is smaller after peripheral than central administration suggests that the peptide is acting on peripheral, as opposed to central nervous system, substrates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nemeroff, C B -- Osbahr, A J 3rd -- Bissette, G -- Jahnke, G -- Lipton, M A -- Prange, A J -- New York, N.Y. -- Science. 1978 May 19;200(4343):793-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/565535" target="_blank"〉PubMed〈/a〉

    Description: Eighteen chronic schizophrenic patients received subcutaneous doses of apomorphine, a dopamine receptor agonist, and of placebo in separate trials. A significant improvement in psychotic symptoms occurred after apomorphine compared to placebo. The results are interpreted as a consequence of presynaptic dopamine receptor activation by apomorphine with a subsequent decrease in dopamine-mediated neural transmission.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tamminga, C A -- Schaffer, M H -- Smith, R C -- Davis, J M -- New York, N.Y. -- Science. 1978 May 5;200(4341):567-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/347574" target="_blank"〉PubMed〈/a〉

    Description: Rifampicin produces a dose-dependent decrease in protein synthesis in rat thymocytes. At concentrations up to 200 micrograms per milliliter, rifampicin does not alter rat thymic transcription. Rifampicin causes a direct inhibition of protein synthesis in rat thymic and hepatic microsomes, and in cadaveric human hepatic microsomes. Protein synthesis inhibition could explain the toxicity of rifampicin in man.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Buss, W C -- Morgan, R -- Guttmann, J -- Barela, T -- Stalter, K -- New York, N.Y. -- Science. 1978 Apr 28;200(4340):432-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/644307" target="_blank"〉PubMed〈/a〉

    Description: Since the induction of sister chromatid exchanges in cultured cells has been shown to be the most sensitive mammalian system to detect the effects of mutagenic carcinogens, Chinese hamster ovary cells and human lymphocytes were exposed to the sodium saccharin found to induce bladder cancer in rats. Both that saccharin and a highly purified extract of it increased the yield of sister chromatid exchanges in both types of cells. The results, which were repeatable and statistically highly significant, indicated that the weak carcinogen, saccharin, is also mutagenic in the sense that it induces cytogenetic changes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wolff, S -- Rodin, B -- New York, N.Y. -- Science. 1978 May 5;200(4341):543-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/644315" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1978-03-17
    Description: One oral dose of pyrazole caused necrosis of rat thyroid follicular epithelial cells but spared the parafollicular (C) cells and the parathyroid glands. Serum thyroxine (T4) and triiodothyronine (T3) were significantly decreased on day 3 after pyrazole administration and were immeasurable on day 5. At day 5 the thyroid was enlarged and the concentration of thyroid-stimulating hormone in the serum was increased, indicating an appropriate pituitary response to a primary lesion in the thyroid. Doses of pyrazole which produced no morphologic change in the thyroids also significantly depressed the concentrations of T4 and T3 in the serum.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Szabo, S -- Horbath, E -- Kovacs, K -- Larsen, P R -- New York, N.Y. -- Science. 1978 Mar 17;199(4334):1209-10.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/628835" target="_blank"〉PubMed〈/a〉
