Tromethamine 10-14 arginine vasopressin Rattus norvegicus 58-61 6653668-2 1983 Equilibration of rat vas deferens muscle strips in Tris containing Tyrode medium caused a significant increase in sensitivity to KCl, but had no effect on the maximum tension induced by NE or KCl. Tromethamine 51-55 arginine vasopressin Rattus norvegicus 21-24 6653668-8 1983 Both F and S components of KCl-induced contractions of rat vas deferens were sensitive to verapamil and these depressant effects were further enhanced in the presence of Tris. Tromethamine 170-174 arginine vasopressin Rattus norvegicus 59-62 6653668-11 1983 We conclude that Tris can exert adverse effects on the contractile properties of rat vas deferens, probably via the disturbance of Ca2+-handling by the smooth muscle membrane and possibly by affecting release of norepinephrine.
