Histopathological examination of the oral mucosa. A HE staining and MT staining of oral ulcer tissue in RAU mice. a: NC(Normal control group); b: RAU-DAY1(After 24 H of membrane formation); c: RAU group; d: EGCG-H group; e: EGCG-L group; f: positive(VC+VB) group (×100/×200 scale bar = 100 μm/50 µm); B volume fraction of collagen fibers in ulcerated tissue in MT staining. *p<0.05, vs. NC group; #p<0.05, vs. RAU group.
