Uterine changes in ovariectomized (OVX) rats treated with the Styphnolobium japonicum fruit (SJF) and germinated soybean embryo (GSE) complex extract. (A) Representative images of dissected uterine tissue from the rats (left panel). Uterine weight (right panel). Scale bar, 1 cm. (B) Representative images of hematoxylin and eosin-stained uterine walls (left panel). Uterine thickness (right panel). Scale bar, 500 µm. The complex extract was prepared by blending the SJF and GSE. 17β-estradiol (E2) was used as a positive control. The results are presented as means ± standard deviation (n = 3). *** p < 0.001, vs. the sham group; # p < 0.05, ## p < 0.01, ### p < 0.001, vs. the OVX group.
