摘要：
The direct effects of bromocriptine on steroidogenesis were examined in cultured porcine granulosa cells. The following observations were made with bromocriptine: (1) It significantly increased the basal or FSH-stimulated secretion of progesterone in cultured porcine granulosa cells at concentrations exceeding 10(-7) mol/l: (2) its inhibitory effect on basal estradiol secretion was demonstrated; (3) it did not influence cell number in cultured porcine granulosa cells: (4) it increased the extracellular accumulation of cAMP in a concentration-dependent manner; and (5) it did not induce a change in cytosolic free Ca2+ concentration. These findings suggest that bromocriptine exerts a direct effect on steroidogenesis in ovarian granulosa cells.
