Abstract:

CONTEXT: Okra, Abelmoschus esculentus (L.) (Malvaceae), is a medicinal plant widely used in Turkish traditional medicine for the treatment of various diseases such as ulcers and gastritis.

OBJECTIVE: In the present study, we evaluated the gastroprotective effect of okra against ethanol-induced acute gastric mucosal injury in animal models.

MATERIALS AND METHODS: Wistar rats were treated with 500, 250 or 100 mg/kg okra; 20 mg/kg famotidine (Fam); and 75 mg/kg quercetin (Que). Following a 60 min period, all the rats were given 1 mL of ethanol (80%). One hour after the administration of ethanol, all groups were sacrificed.

RESULTS: At 5000 mg/kg, the extract produced (okra) no signs of toxicity in animals. Okra 500, 250, 100, Fam 20 and Que 75 inhibited ulcer formation by 81.0, 67.5, 67.0, 76.3 and 72.4%, respectively. Okra 500 significantly decreased edema, hemorrhage and inflammation scores compared with the ethanol group (p < 0.05). The oxidant levels decreased significantly in the all study groups compared within ethanol group (p < 0.001). Serum β-carotene and retinol levels significantly increased 40.2 and 45.4% in the okra 500 group. In okra 500, 250 and Fam 20 groups, apoptosis significantly decreased (p < 0.001), while okra 500, 250 and Fam 20 groups showed a higher percentage of cell proliferation compared with the ethanol group (p < 0.001).

DISCUSSION AND CONCLUSIONS: Our in vivo data indicate that okra has a gastroprotective effect against ethanol and could reduce the gastric ulcer as seen from biochemical and histopathological results. We suggest that okra could be a possible therapeutic antiulcer agent.
