    Beschreibung: Calcium ionophore A23187 promotes ooplasmic segregation and orange crescent formation in eggs of the ascidian Boltenia villosa. When eggs were exposed to a gradient A23187 the orange crescent was induced to form in the region corresponding to the highest concentration of ionophore. This result is consistent with the hypothesis that a local increase in intracellular calcium polarizes cytoplasmic localization in the ascidian embryo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jeffery, W R -- 232-HDO-7098/HD/NICHD NIH HHS/ -- HD-13970/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1982 Apr 30;216(4545):545-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6803360" target="_blank"〉PubMed〈/a〉

    Beschreibung: Phencyclidine elicits hyperthermia at low doses and hypothermia at high doses in rats. Naloxone antagonizes both effects.

    Beschreibung: Somatostatin perfused in canine pancreases at 10 to 20 picograms per milliliter or 10 to 20 percent of the pancreatic vein somatostatin concentration inhibited insulin and glucagon secretion. This suggests that the high local concentration of endogenous somatostatin is not in contact with somatostatin receptors of the islets. The integrity of this separation may determine the sensitivity of islet cells to circulating somatostatin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kawai, K -- Ipp, E -- Orci, L -- Perrelet, A -- Unger, R H -- New York, N.Y. -- Science. 1982 Oct 29;218(4571):477-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6126931" target="_blank"〉PubMed〈/a〉

    Beschreibung: Specific receptors for gonadotropin-releasing hormone (GnRH) in cultured rat pituitary cells were increased by subnanomolar concentrations of GnRH agonists and decreased by high concentrations of these peptides. The antagonist [D-Phe2, Pro3, D-Phe6]GnRH did not alter GnRH binding capacity and blocked the increase in sites induced by GnRH. These findings provide direct evidence for the homologous regulation of GnRH receptors by physiological concentrations of the hypothalamic peptide, an action that could mediate the cyclical and postcastration increases in GnRH receptors and responsiveness of the pituitary gonadotrophs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Loumaye, E -- Catt, K J -- New York, N.Y. -- Science. 1982 Feb 19;215(4535):983-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6296998" target="_blank"〉PubMed〈/a〉

    Beschreibung: A model of "overdose" deaths among heroin addicts is proposed which emphasizes recent findings concerning the contribution of drug-associated environmental cues to drug tolerance.

    Beschreibung: Maximum expiratory flow rate at 30 percent of vital capacity above residual volume served as an index of airway obstruction in comparing the effects of leukotriene C and histamine administered by aerosol to five normal persons. Leukotriene C was 600 to 9500 times more potent than histamine on a molar basis in producing an equivalent decrement in the residual volume. The leukotriene C response was slow in onset and prolonged, reminiscent of the effects of aerosol allergen challenge in asthmatic allergic subjects.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weiss, J W -- Drazen, J M -- Coles, N -- McFadden, E R Jr -- Weller, P F -- Corey, E J -- Lewis, R A -- Austen, K F -- AI-00399/AI/NIAID NIH HHS/ -- AI-07722/AI/NIAID NIH HHS/ -- AI-10356/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1982 Apr 9;216(4542):196-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7063880" target="_blank"〉PubMed〈/a〉

    Beschreibung: When injected continuously into the lateral ventricles of the rat, somatostatin increased the frequency of the migrating myoelectric complexes of the small intestine in a dose-related manner. A significant increase was obtained at a dose as low as 0.066 picomole per minute. In contrast, cholecystokinin octapeptide decreased the frequency of the migrating myoelectric complex of the small intestine or disrupted this pattern when injected into the lateral ventricle at rates of 0.073 to 0.23 picomole per minute. These findings support the hypothesis that somatostatin and cholecystokinin octapeptide act on central nervous system structures that are involved in the control of intestinal motility.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bueno, L -- Ferre, J P -- New York, N.Y. -- Science. 1982 Jun 25;216(4553):1427-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6124037" target="_blank"〉PubMed〈/a〉

    Beschreibung: The population dynamics of single-cell stimulation was analyzed by monitoring autofluorescence by flow cytometry. Stimulation of the respiratory burst in human neutrophils by 12-O-tetradecanoyl phorbol-13-acetate (TPA) caused a decline in highly fluorescent cells (characteristic of resting neutrophils) and a corresponding increase in the number of weakly fluorescent cells (characteristic of activated neutrophils). Increasing concentrations of TPA caused increasing numbers of cells to shift from the highly fluorescent population to the weakly fluorescent population without the appearance of intermediate populations. Thus the neutrophil respiratory burst, a component of neutrophil cytotoxic response, is triggered in an all-or none fashion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hafeman, D G -- McConnell, H M -- Gray, J W -- Dean, P N -- 2R01 AI13587/AI/NIAID NIH HHS/ -- CA14533/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1982 Feb 5;215(4533):673-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6800035" target="_blank"〉PubMed〈/a〉

    Beschreibung: A low intake of dietary cadmium induces specific dose-dependent functional and biochemical changes in the cardiovascular tissues of rats. Maximum changes occur when the cadmium intake is 10 to 20 micrograms per kilogram of body weight per day. The changes reflect the accumulation of "critical" concentrations of cadmium in the cardiovascular tissues. The biologic activity of cadmium is demonstrated for intakes that approach those of the average American adult exposed to the usual environmental concentrations of the element but not to industrial concentrations. The sensitivity of the cardiovascular system to low doses of cadmium could not be anticipated by extrapolation from data on exposure to high concentrations of cadmium. The data support the hypothesis that ingested or inhaled environmental cadmium may contribute to essential hypertension in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kopp, S J -- Glonek, T -- Perry, H M Jr -- Erlanger, M -- Perry, E F -- ESO2397/ES/NIEHS NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 27;217(4562):837-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6213041" target="_blank"〉PubMed〈/a〉

    Beschreibung: alpha-Factor, a tridecapeptide mating pheromone of yeast (Saccharomyces cerevisiae), has extensive sequence homology with the hypothalamic decapeptide gonadotropin-releasing hormone (GnRH). Both synthetic and natural preparations of alpha-mating factor were found to bind specifically to rat pituitary GnRH receptors and to stimulate the release of luteinizing hormone from cultured gonadotrophs. The ability of the yeast pheromone to reproduce the biological actions of GnRH in the mammalian pituitary gland indicates that the structural and functional properties of GnRH-related peptides may have been highly conserved during evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Loumaye, E -- Thorner, J -- Catt, K J -- New York, N.Y. -- Science. 1982 Dec 24;218(4579):1323-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6293058" target="_blank"〉PubMed〈/a〉

    Beschreibung: Concentrations of prolactin and growth hormone in the serum of rats were significantly increased by morphine. Dose response studies demonstrated that maximum prolactin release required lower doses of morphine than those needed for the maximum growth hormone response. Selective blockade of mu 1 (high affinity) opiate receptor with the irreversible antagonist naloxazone reduced morphine-induced peak concentrations of prolactin by 80 percent while increasing peak growth hormone levels by 250 percent. These results suggest different receptor mechanisms for the opiate modulation of the two hormones. The mu 1 (high affinity) receptor sites appear to mediate the morphine-induced release of prolactin but not growth hormone.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Spiegel, K -- Kourides, I A -- Pasternak, G W -- CA 23185/CA/NCI NIH HHS/ -- DA 002615/DA/NIDA NIH HHS/ -- P32 GM07547/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 20;217(4561):745-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6285470" target="_blank"〉PubMed〈/a〉
