Type-2 induced dyslipidemia and oxidative stress is prevalent world over and is being managed through pharmacological treatment. There are some dietary components such as Zn, Cu, Mg Mn, vitamin- E, C, omega-3 fatty acids which have shown to reduce the severity of oxidative stress associated with type-2 diabetes mellitus. In view of this information, the efficacy of modified poultry egg (Patent Application No 2264 Del-2005) enriched with optimum minerals, vitamin E and omega-3 fatty acids was studied on dyslipidemia and oxidative stress of type-2 diabetes mellitus induced rats. In this study, the type-2 diabetes mellitus in the rats was induced by increasing Zn concentration in semi-synthetic diet rich in fat and refined sugar according to Taneja et al., 2006. Accordingly, control diet-I (diet-I-C) consisted of basal diet containing 20mg Zn/kg diet was fed on control group-I and diabetes inducing diet (diet-II-ZS-DB) containing 80 mg/kg semisynthetic diet on group-II for a period of 180 days. The arterial blood pressure and heart rate was significantly higher in group-II than their control counterpart. The blood profile after 180 days of dietary treatment displayed a significant rise in glucose, total lipids, cholesterol, triglycerides, LDL-cholesterol, VLDL- cholesterol whereas HDL- cholesterol showed a reduction in their level. The estimation of minerals in this group of rats revealed a higher Zn and lower Cu, Mg and Mn levels in liver and kidney. Their lipid peroxidation products were higher and the enzyme activities of superoxide dismutase, catalase, glutathione-s-transferase, glutathione reductase, glutathione (reduced) and glucose -6- phosphate dehydrogenase were significantly lower as compared to control group-I. In order to see the efficacy of the modified eggs, some type-2 diabetes mellitus induced rats from the Group-II were separated on day 90 and label as Group- III and fed on modified eggs mixed diet (4 liquid eggs/kg diet mixed with diabetes inducing diet) for another 90 days completing 180 days from the start of the experiment. A significant reduction in the blood pressure and heart rates, serum glucose, serum lipid profile, the lipid peroxidation products and a significant increase in the activities of enzymes per se with reversal of Zn, Cu, Mg and Mn levels closer to the control group were recorded in the Group-III rats. The data suggest that the modified egg can ameliorate the dyslipidemia and oxidative stress in type-2 diabetes mellitus induced rats by improving the mineral status in their body
