Fig. 5From: The effect of hydroalcoholic extract of Psidium guajava L. on experimentally induced oral mucosal wound in ratHistopathological features at 14 days post‐wounding H&E staining with magnification at × 100. A Healthy control rats with normal tissue structure, B wound group with an increment in Deep and extensive ulceration, necrosis of cells and sloughing (shedding) of necrotic and inflammatory cells, severe polymorphonuclear infiltration, and granulation tissue formation. C W + N.S group with increment ulceration, granulation tissue formation, with acute and chronic inflammatory infiltrate. D, E oral mucosal wound rats treated with phenytoin and guajava extract showed Re-epithelialization, late granulation tissue (fibroblastic proliferation), and little mononuclear inflammatories infiltrateBack to article page
