    Alcohol-induced spasms of cerebral blood vessels: relation to cerebrovascular accidents and sudden death (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-04-15
    Description: Ethyl alcohol produced graded contractile responses in rat cerebral arterioles and venules in vivo and in isolated canine basilar and middle cerebral arteries at a concentration range (10 to 500 milligrams per deciliter) which parallels that needed for its graded effects of euphoria, mental haziness, muscular incoordination, stupor, and coma in humans. Two specific calcium antagonists, nimodipine and verapamil, prevented or reversed the alcohol-induced cerebrovasospasm and thus may prove valuable in treating the hypertension and stroke observed in heavy users of alcohol.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Altura, B M -- Altura, B T -- Gebrewold, A -- DA02339/DA/NIDA NIH HHS/ -- HL29600/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1983 Apr 15;220(4594):331-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6836278" target="_blank"〉PubMed〈/a〉

    Magnesium deficiency-induced spasms of umbilical vessels: relation to preeclampsia, hypertension, growth retardation (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-07-22
    Description: Isolated umbilical arteries and veins, obtained from normal women at the end of pregnancy, were incubated in krebs-Ringer bicarbonate solution and exposed to magnesium at concentrations ranging from 0 to 9.6 millimoles per liter. The basal tension of the vessels increased when magnesium was withdrawn and decreased when the concentration of magnesium was raised. Absence of magnesium in the medium significantly potentiated the contractile response of the vessels to bradykinin, angiotensin II, serotonin, and prostaglandin F2 alpha. It appears that magnesium deficiency may be responsible for spasms of umbilical and placental vasculature. Our findings may provide a rationale for why magnesium sulfate is an effective therapy in preeclamptic syndromes in pregnant women.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Altura, B M -- Altura, B T -- Carella, A -- HL 18015/HL/NHLBI NIH HHS/ -- HL 29600/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1983 Jul 22;221(4608):376-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6867714" target="_blank"〉PubMed〈/a〉
