Objective:
To observe the in vivo effect of traditional chinese medicine (TCM) Shu-Gan-Liang-Xue (SGLX) decoction on estrogen in vivo in mice.
Methods:
Mice were randomly divided into control, tamoxifen (TAM), SGLX and SGLX + TAM groups. After SGLX decoction had been given to mice for 21 days, the serum hormone level of mice was tested by radioimmunological method, uterine weight index was obtained by uterine weight divided by body weight. Endometrial change was pathologically observed.
Results:
SGLX decoction reduced the level of serum estrogen more than the control with significant difference (P < 0.001). Uterine weight index was more lowered in the SGLX group than the control giving a difference but not significant. The endometrium in the SGLX group showed no change when compared with that of the control, but the SGLX + TAM group showed slightly more endometrial hyperplasia than the TAM group.
Conclusion:
SGLX decoction, having synergistic effect on TAM, can reduce serum hormone level and alleviate the endometrial hypertrophy side effect of TAM.
