title: Effects of tokishakuyakusan and keishibukuryogan on steroidogenesis by rat preovulatory follicles in vivo.
abstract: The effect of Tokishakuyakusan (TS) and Keishibukuryogan (KB) on estradiol-17 beta, progesterone and testosterone in serum and ovarian tissue from PMS-treated immature rats was examined in vivo. The in vivo intravenous administration of 20 micrograms of TS or KB increased the concentrations of estradiol-17 beta, progesterone and testosterone. These results suggest that TS and KB stimulate in vivo the production of estradiol-17 beta, progesterone and testosterone by preovulatory follicles, and that TS stimulation is more effective than KB.
