Although accurate and continuous assessment of cerebral vasculature status is highly desirable for managing cerebral vascular diseases, no such method exists for current clinical practice. The present work introduces a novel method for real-time detection of cerebral vasodilatation and vasoconstriction using pulse morphological template matching. Templates consisting of morphological metrics of...
We tested the hypothesis that dexmedetomidine (Dex) has greater alpha(2)- vs. alpha(1) selectivity than clonidine and causes more alpha(2)-selective vasoconstriction in the human forearm. After local beta-adrenergic blockade with propranolol, forearm blood flow (plethysmography) responses to brachial artery administration of Dex, clonidine, and phenylephrine (alpha(1)-agonist) were determined i...
HASRIMOTO, K. and KOKUBUN, H. Interaction between Adenosine Compounds and Norepinephrine in Dog Renal Circulation. Tohoku J. exp. Med., 1972, 107 (4), 373-380 -Drugs were administered to anesthetized dogs directly into the left renal artery perfused with animal's own blood at a constant pressure. A single injection of adenosine caused prompt renal vasoconstriction, while an infusion of adenosin...
