Effect of DKTP on uterus in perimenopausal rats: (a) exfoliative epithelia in vaginal smears of the female rats with regular 4-day estrus cycles by HE staining methods, displayed with a final magnification of 200x; (b) estradiol concentration; (c) the ratio of uterine wet weight to bodyweight (UWW/BW); (d) HE staining results of paraffin sections of rat uterus, displayed with a final magnification of 200x. ^∗∗p < 0.01 and ^∗∗∗p < 0.001, compared with the control group; ^#p < 0.05 and ^##p < 0.01, compared with the nilestriol group; ns, no significant difference.
