Photomicrograph from stomach tissues for the protective effects of C. ignea aerial parts extract against ethanol induced gastric ulceration in rats. Histopathological tissue sections were stained with H&E stain. In control rats; gastric mucosa showed intact villi with no hemorrhages or exfoliations (a × 100). EtOH group; showed severe intervillus hemorrhages in gastric mucosa (black arrow) accompanied with severe desquamations in mucous cells (yellow arrow) (b₁ × 200). Severe coaggulative necrosis in gastric villi (black arrows) was noticed (b₂ × 200). In Ranitidine group; mucous cell desquamations of gastric villi (yellow arrow) and pyloric glands (black arrows) are pronounced (c × 100). In C. ignea 250 mg/kg and 500 mg/kg groups respectively the gastric tissue is histologically normal (d and f × 100). EtOH + C. ignea 250 mg/kg and EtOH + C. ignea 500 mg/kg groups; the lining epithelium of the gastric mucosa showed no exfoliations in the mucous cell, also no submucosal hemorrhages (e and g × 100)
