Diabetes mellitus, as a result of microvascular and macrovascular injury, causes organ dysfunction in a wide variety of tissues. The objective of this study was to investigate the effect of combined inositol hexakisphosphate and inositol supplement on renal and pancreatic integrity in type 2 diabetic rats. Thirty male Sprague-Dawley rats were divided into five groups (n=6 per group). Type 2 diabetes was induced in three groups using high-fat diet combined with a single dose of streptozotocin (35mg/kg body weight, intraperitoneally). Two of the diabetic groups were treated with combined IP6 and inositol or glibenclamide. Serum biochemical markers of kidney damage kidney, antioxidant status (superoxide dismutase (SOD), catalase (CAT) and reduced glutathione (GSH) and lipid peroxidation were measured. Histomorphological and morphometric examinations of the H&E stained pancreas were also carried out. The administration of combined IP6 and inositol supplement resulted in 64% and 27% increase in CAT activities and GSH levels respectively and a 25% decrease in lipid peroxidation level compared to the diabetic control. Serum uric acid, creatinine and BUN levels in the combination treated group was comparable to the normal control. Examination of H&E stained pancreatic sections showed a significant increase (107%) in the number of islets in the combined IP6 and inositol treated group compared to the untreated diabetic group. Overall, the treatment of type 2 diabetic rats with combined IP6 and inositol supplement resulted in the improvement of renal and pancreatic function.
