Effect of D-400, a herbomineral formulation on liver glycogen content and microscopic structure of pancreas and liver in streptozotocin induced diabetes in rats.
Streptozotocin induces severe and irreversible hyperglycaemia in experimental animals. The effect of oral administration of D-400 (1 gm/kg/day), a herbomineral formulation on streptozotocin induced-diabetes was studied in rats. Liver glycogen content was assayed biochemically on 2,4 and 8 weeks after D-400 treatment. Superoxide dismutase(SOD) activity of pancreatic islet cells was assessed on 8th week of D-400 treatment. The microscopic structure of pancreas and liver were examined in both control and treated animals. D-400 treatment showed progressive and significant increase in liver glycogen at 2,4 and 8 weeks respectively. Streptozotocin induced a decrease in pancreatic islet cell superoxide dismutase which was reversed by D-400 treatment for a period of 8 weeks. The free radical scavenging activity of D-400 may be attributed to shilajeet, one of its important ingredient. Streptozotocin induced histopathological changes in pancreas and liver was also partially reversed by D-400. The findings indicate that D-400 helps in improving the glycogen stores in the liver and prevents the streptozotocin induced damage through free radicals by increasing the islet cell superoxide dismutase activity.
