Effects of hachimijiogan, tokishakuyakusan and keishibukuryogan on the corpus luteum function and weights of various organs in vivo.
27-day-old female rats received 20 IU PMS and 56 hours later, 40 IU hCG and were orally given with 20 or 200 micrograms of Hachimijiogan (TJ-7), Tokishakuyakusan (TJ-23) or Keishibukuryogan (TJ-25) daily for 3 or 5 days before sacrifice. Seven days after hCG treatment, the serum and ovarian tissue were assayed for progestins. 200 micrograms/day of TJ-23 significantly (p less than 0.05) decreased the progesterone and 17 alpha-hydroxyprogesterone levels, whereas it significantly (p less than 0.01) increased 20 alpha-hydroxyprogesterone. TJ-7 and TJ-25 showed a tendency to decrease these progestins. These results suggest that TJ-23 has a luteolytic effect on the corpus luteum in vivo.
