[Effect of bradykinin and D 600 on calcium transport by rat myometrial plasma membranes].

Main characteristics of 45Ca accumulation by myometrum plasma membrane were obtained. It was shown that bradykinin and D 600 significantly altered calcium accumulation by the membrane vesicles. Bradykinin increases the rate of calcium accumulation and D 600 suppresses general accumulation and abolishes bradykinin stimulation of this process. The obtained evidence indicates that bradykinin interaction with the membrane receptor results in activation of calcium transport across the myometrium plasma membrane.
