Abstract

Various studies have indicated that peptic ulcers occurring during the course of diabetic state are more severe and often associated with complications such as gastrointestinal bleeding. This study is the first attempt to understand the pathogenesis of gastric ulcers occurring during the diabetic state considering alternate biochemical pathways using suitable markers and its amelioration by Cuminum cyminum. In this study, diabetic rats showed a progressive increase in the stomach advanced glycated end products formation, gastric mucosal tumour necrosis factor-α and Thiobarbituric acid reactive substances levels as compared to normal control (nondiabetic) rats. There was decrease in gastric mucosal content, antioxidant enzymes and cellular ATPase enzyme levels of diabetic gastric mucosa when compared to the normal control group. mRNA expression of epidermal growth factor was found to be significantly higher as compared to normal control animals. Further methanol extract of Cuminum cyminum treatment to diabetic animals caused a reduction in blood glucose, and ulcer score when compared to diabetic control rats. It significantly increased gastric mucus content, antioxidant status and cellular ATPase enzyme levels as compared to diabetic control animals. Methanol extract of Cuminum cyminum inhibited advanced glycated end products formation in vitro as well as in vivo.
