| Abstract | ||||
| Diabetes mellitus represents a major public health problem. Much of the increased mortality and morbidity seen in diabetic patients is the result of various complications. Free radicals play an important role in the cause of complications of diabetes mellitus such as retinopathy, nephropathy, hypertension, arteriosclerosis and ischemic heart diseases. Many secondary plant metabolites have been shown to possess antioxidant activities, improving the effects of oxidative stress in diabetic patient. Thus the present study tries to evaluate the role of different preparations from Lupinus termis as a hypoglycemic agent. Alloxan diabetic rats were orally treated with either 5 ml/Kg b.wt/day aqueous lupine seeds extract or 20% w/w in diet edible boiled lupine seeds powder or 20% w/w dry lupine seeds powder for 30 days. The results recorded high levels of glucose, total cholesterol, triglycerides and LDL-cholesterol as well as low levels of total protein, HDL-cholesterol, liver glycogen and serum insulin in diabetic rats. Phospholipids content was increased in the serum but decreased in the liver and pancreas of diabetic rats. In addition, the results confirmed that the alloxan diabetic rats were subjected to oxidative stress as indicated by the extent of lipid peroxidation (high malondialdehide levels) present in the liver and pancreas and significantly alter activities of some scavenging enzymes (low glutathione reductase, glucose-6-phosphate dehydrogenase, superoxide dismutase and catalase). On the other hand, after administration of any one of the used preparations of lupine seeds, the diabetic rats revealed an improvement on various metabolic abnormalities as well as oxidative stress recorded with diabetes but the best improvement occurred in the animal group treated with dry seeds powder. These results give a good evidence for the amelioration effect of lupine against the alloxan diabetic effects. | ||||
