Abstract The signal pathway for bradykinin-induced contraction of the uterine smooth muscle was investigated by comparing the effect of blocking agents on bradykinin and oxytocin induced contractions of the isolated rat uterus in organ bath. The phospholipase C inhibitor U-73,122 abolished the effect of both bradykinin and oxytocin. Inhibition of non-voltage-dependent Ca2+ influx by SK & F 96,365 reduced the contraction induced by both agonists to about 20\% of control. The tissues failed to contract when they were exposed to bradykinin or oxytocin in Ca(2+)-free Krebs-Henseleit buffer with 2 mM EDTA. Both bradykinin and oxytocin induced further contraction when the tissues were partially depolarized and partially contracted by 30 mM KCl. These observations suggest that bradykinin, like oxytocin, activates phospholipase C which generates IP3 with a subsequent release of Ca2+ from intracellular stores followed by store-operated Ca2+ influx. Thus, membrane potential independent steps appear to be important in bradykinin-induced contraction in the rat uterus.
