Abstract


To investigate the effects of aluminum chloride (AlCl3) in the deviation of tissue lipid profiles and ways to reduce its effect using antioxidant vitamins C and E, thirty-six male albino rats (120-150g) were divided into six groups with six rats each. Group (1) received normal saline and served as control, Group (2) was administered with AlCl3 (20mg/kg body weight b.wt)), Group (3) was administered with vitamin C (200mg/kg b.wt), Group (4) was administered with vitamin E (200mg/kg b.wt), Groups (5) and (6) were administered aluminium (20mg/kg b.wt) along with vitamins C and E (200mg/kg b.wt) respectively. At the end of the experiment, blood samples and organs (liver, testis, heart, kidney and brain) were harvested and used for lipid profile determination. The results showed that oral administration of aluminum significantly (p<0.05) increased cholesterol level in plasma and VLDL+LDL and significantly decreased in erythrocyte, HDL and testis. Cholesterogenesis was induced in the brain, liver, kidney and heart. Plasma and VLDL+LDL triglyceride were significantly (p<0.05) increased while erythrocyte and brain triglyceride were significantly decreased. Plasma, VLDL+LDL and brain phospholipid levels were significantly (p<0.05) decreased and that of erythrocyte significantly increased. There was no significant difference (p>0.05) in rats supplemented with vitamin C and vitamin E compared with control. The vitamins significantly attenuated the affected lipid levels in the tissues affected. It was concluded that administration of vitamin C and vitamin E supplements may be used as therapies against the effects of Aluminium exposure on lipids.
