Effects of ethyl acetate fraction of AHE on uterine hyperplasia. After treatment with the ethyl acetate fraction of AHE or stigmasterol for 2 weeks in the DES/MPA-induced uterine hyperplasia mice model, uteri were harvested, formalin-fixed, and paraffin-embedded. (A) Four micrometer cross-sections of tissues were collected onto slides and then stained with hematoxylin and eosin (H&E). Magnification: 200×. (B) Quantitative analysis of the width of the myometrial area in a cross-section. Data represent means ± SEM (n = 5). * p < 0.05 compared with the control group. #
p < 0.05, ##
p < 0.01 compared with the MC group. L, luminal space. M, myometrium. MC, model control. STL, stigmasterol.
