Estrogenic Effect of the Extract of QingYan Formula on Reproductive Tissues in Immature Mice

Figure 2

The effect of QingYan formula extract (QYFE) on uterine weight in immature mice. The uterine weights of immature mice were measured at the end of the 7-day treatment period. Immature mice treated with QYFE (1, 2, or 4 g/kg) or estradiol valerate (EV) had significantly higher uterus index compared with the untreated control group, showing that QYFE can promote uterine growth. Data are the mean ± standard deviation (SD) of samples from 10 mice. P values are for the one-way analysis of variance (ANOVA) comparing treatment group with untreated immature mice. P < 0.001, P < 0.01, and P < 0.05 compared with the control group.
