Abstract

Diabetes has been reported to increase propensity to peptic ulceration through its effect both on offensive and defensive mucosal factors. Seeds of Eugenia jambolana (EJ) have been reported to have both antidiabetic as well as ulcer protective effects. The present study evaluates the antidiabetic effects of ethanolic extract of dried seed kernel of Eugenia jambolana (EJE) and its comparative effect on gastric ulceration and acidpepsin secretion with standard antisecretory FL-blocker. Ranitidine and antidiabetic glibenclamide with a premise that Eugenia jambolana may show better ulcer healing effects by promoting defensive or reducing offensive mucosal factors in mild diabetes (MD) rats. MD was produced in adult rats by administration of streptozotocin (45 mg/kg, ip). EJE was given orally in the doses of 100-400 mg/kg for 10 days and in the dose of 200 mg/kg for 30 days respectively to study its dose- and time-dependent effects on various diabetic parameters like blood glucose, serum cholesterol and triglycerides, insulin level and glycosylated hemoglobin. For ulcer protective and gastric secretion studies, EJE (200 mg/kg) was given orally for 10 days against 2 h cold restraint stress (CRS)-, 4 h pylorus ligation (PL), aspirin (ASP, 200 mg/kg, 4 h) - and 95% ethanol (EtOH, 1 ml/200 g, 1 h)-induced gastric ulcers and offensive acid-pepsin secretion after 4 h PL with cooccurring MD in rats. EJE showed dose-dependent decrease in blood glucose level in MD rats. Blood glucose level remained stable in mild diabetic rats from 3rd day onwards after streptozotocin administration (taken as 1st day for treatment) and EJE (200 mg/kg) showed anti-hyperglycemic effect on 10th day of its administration. Further, EJE in the above dose also decreased cholesterol level with little or no effect on triglycerides level and reversed the decrease and increase in insulin and glycosylated hemoglobin level near to the normal level as observed alter 30 days treatment in MD rats. MD rats exhibited an increased propensity to gastric ulceration induced by CRS, ASP, EtOH and PL and caused increase in acid-pepsin secretion. EJE was not only effective in reversing the increased propensity to ulceration in diabetic rats but also decreased the acid-pepsin output better than glibenclamide. The ulcer protective effect of Eugenia Jambolana seems to be due to its antidiabetic and gastric antisecretory effects.
