Abstract
Aim:The aim of the present study is to evaluate the gastroprotective effect of hydroalcoholic extract of Andrographis paniculata (HAEAP) in male albino wistar rats.Materials and Methods:Rats were pretreated with HAEAP (100,200,500mg/kg b. wt for 30 days) and then gastric ulcers were induced by ethanol, aspirin, pylorus ligation and cold restraint stress models. Ulcer score was determined in all the ulcer models. pH, gastric volume, titrable acidity, pepsin, mucin, myeloperoxidase, H+K+ATPase, thiobarbituric acid reacting substances (TBARS) and antioxidant enzyme activities were assayed in ethanol-administered rats.Results:The ulcer score was found to be low in HAEAP-pretreated rats. Among the doses studied, 200 mg/kg b.wt was found to be optimum for significant ulcer reduction. The test drug significantly reduced the acidity, pepsin concentration, myeloperoxidase and H+K+ATPase activities in ethanol-administered rats. The elevated TBARS and decreased glutathione (GSH) and mucin levels observed during ulcerogenesis were found to be altered in HAEAP-received animals.Conclusions:The ulcer preventing effect of HAEAP may partly be due to its regulating effect on H+K+ATPase activity and /or mucin preserving effects. The flavonoids present in the HAEAP might be responsible for the gastroprotective action probably by maintaining the antioxidants and thiol status in the gastrointestinal tract.
