The present study is an attempt to confirm that hyperproteinemia, diabetes, and iron overload are members of oxidative stress, which may able us to compare the treatment between green tea and desferal drug in sera of rabbits induced with diabetes mellitus. Fourteen male rabbits divided into two groups, one as control diet (n=5), the other (n=9) with control diet in addition to ferrosam. While the treatment of 2 nd group after three months of experimental conditions done by green tea to one subgroup (n=5) and the other subgroup (n=4) with desferal. The results revealed that treatment with green tea can prevent the effect of iron overload on the antioxidant levels and other biological parameters at the same action of desferal. Key words: Desferal, Green Tea, Lipid Profile, Diabetes Mellitus, Iron Overload, Antioxidant. Introduction Iron and iron overload catalytic ability lies in the redox activity of iron, which is able to cycle between two stable configurations, ferric (Fe +3 ) and ferrous (Fe +2 ) states, allowing it to act as an electron donor and acceptor. The biological importance of iron
