Modulatory Effect Of Zingerone Against Stz-Nicotinamide Induced Type-2 Diabetes Mellitus In Rats

The objective of this research was to explore the role of zingerone on hyperglycemia, hyperlipidemia, insulin level, oxidative biochemical markers and histological alterations in beta-cells of type-2 diabetic rats. The outcome of this study illustrates reduction in glucose and insulin levels significantly in zingerone-treated diabetic groups. Lipid parameters were resumed to normal in zingerone-treated diabetic group as demonstrated by significant reduction in triglycerides, cholesterols (total, low-density and very low-density) levels along with significant increase high-density cholesterols levels. Zingerone-treated diabetic groups exhibited significant reduction in LPO levels and restoration of GSH contents. Administration of zingerone to treated diabetic groups indicated improvement in antioxidant enzymes (GPx, GR, GST, SOD and CAT). Administration of zingerone to treated diabetic groups minimized degeneration of pancreatic beta-cells as witnessed from histopathological studies. Our results demonstrate that zingerone modulates hyperglycaemia, hyperlipidaemia, oxidative biochemical markers and degenerative changes in beta-cells of treated diabetic groups.
