Description:
Fasting lowers blood pressure to a greater extent in spontaneously hypertensive rats than in normotensive rats. While fasting reduced cardiac sympathetic activity to an equivalent extent in both groups of animals, only in the hypertensive rats did fasting elicit an opiate-mediated vasodepressor response that was independent of sympathetic withdrawal. Both sympathetic nervous system suppression and endogenous opiate activation, therefore, may contribute to the hypotensive effect of fasting in the spontaneously hypertensive rat.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Einhorn, D -- Young, J B -- Landberg, L -- AM 20378/AM/NIADDK NIH HHS/ -- HL 24084/HL/NHLBI NIH HHS/ -- RR 76/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 20;217(4561):727-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7100917" target="_blank"〉PubMed〈/a〉
