Different Sensitivity Changes of Canine and Simian Femoral Arterial and Venous Constrictions by Cooling

[摘要] References(12)Cited-By(6)Using the cannula inserting method, effects of cooling (from 37°C to 27°C) on norepinephrine (NE)- and KCI-induced vasoconstrictions were investigated in isolated, perfused simian and canine femoral arteries and veins. KCI-induced constrictions were much greater in simian vessels than in canine vessels. NE-induced constrictions were similar in both arteries, but were greater in simian veins than in canine veins. In both arteries, NE- and KCI-induced vasoconstrictions were markedly depressed to almost the same degree by cooling. In both veins, the vasoconstrictions were not significantly affected by cooling.
