Thickness of epithelium, lamina propria, the smooth muscle layer, and adventitia. (A,C,D) The thickness of the epithelium. Significant differences were observed among rats, but not among segments (stained with hematoxylin and eosin). (B,E,F) The thickness of smooth muscle layers (anti-α-actin antibody immunohistochemical staining). Significant differences observed among segments indicated thickness of upper and lower vaginal smooth muscle layers were different. (G) The thickness of lamina propria. (H) The thickness of the adventitia. *, P<0.05.
