OBJECTIVE To investigate the protective effect of total alkaloids of Rhizoma Corydalis (TARC) on experimental gastric mucosal lesions in rats. METHODS Gastric mucosal lesions were induced in rats by injecting acetic acid under gastric mucosal. From the 2nd day post the preparation of the rat model, cimetidine 400 mg · kg-1 or TARC 20, 40 and 80 mg · kg-1 was ig delivered for 15 d in different groups. Two days after the last delivery, gastric juice volume and total acidity were measured. Histopathology of stomach tissues was observed by HE staining. The area of gastric ulcer area was measured and the ulcer index and ulcer inhibitory rate were calculated. The expression of epidermal growth factor (EGF) and EGF receptor (EGFR) was detected by immunohistochemical staining. RESULTS Comparing with shame group, the eare of gastric ulcer and ulcer index were increased signifi?cantly in the model group(P<0.01), suggesting that the model rats were prepared properly. Compared with the model group, the ulcer area in rats of cimetidine and TARC 80 mg·kg-1 groups was decreased by 39.9%and 23.7%,respectively. The ulcer index was decreased by 52.3%and 30.5%,respectively. There was no significant difference between the cimetidine group and TARC 80 mg · kg-1 group, in the ulcer area or index. Compared with model group, EGF protein expression of cimetidine and TARC 40 and 80 mg · kg-1 groups was increased by 81.8%,24.2%and 57.6%,respectively while EGFR protein expression was increased by 45.9%,16.2%and 29.7%,respectively(P<0.05,P<0.01). Deciduous and necrotic gastric mucosal and a large amount of inflmmatory cells infiltration were observed in model group, and gastric mucosal lesions were improved in cimetidine and TARC 40 and 80 mg · kg-1 groups. CONCLUSION TARC has protective effect on gastric mucosal lesions in rats. The mechanism may be related to the increase of EGF and EGFR protein expression.
