Trigonella foenum graecum is a well-known hypoglycemic agent used in traditional Indian medicines. It was previously reported that oral administration of its seed powder for 3 weeks to alloxan diabetic rats stabilized glucose homeostasis and free radical metabolism in liver and kidney. In the present study, we further investigated the effects of 3 weeks alloxan induced diabetes on the histological structure and function of liver and kidney and the protective effect of T. foenum graecum seed powder (TSP) oral administration to the diabetic rats utilizing enzyme analysis and light and transmission electron microscopy. The activity of the enzyme, glutamate dehydrogenase was significantly higher whereas the activity of d-β-hydroxybutyrate dehydrogenase enzyme was significantly lower in liver and kidney of alloxan-induced diabetic rats. Histopathological studies showed liver degenerative and early nephropathic changes in diabetic rats. Ultrastructure of the diabetic liver revealed a reduction in the rough endoplasmic reticulum and swelling of mitochondria in the hepatocytes. TSP treatment to the diabetic rats effectively prevented the alteration in the activities of the two enzymes and partially prevented the structural abnormalities thus suggesting a protective effect of TSP on the liver and kidney of the diabetic rats. The role of TSP in reversing the diabetic state at the cellular level besides the metabolic normalization further proves its potential as an antidiabetic agent.
