Effect of phenolic compounds Extraction of Green tea (Camellia sinsis. L) On the Glutathione of Alloxan Experimental InducedDiabeticRabbit.


Diabetes Mellitus ;, considered u; a member of oxtdutie stress syndrome. It is
ns><><:iated with an imbalance b<:tween types of free radica ls and scavenger's system.
lllis stud> showed the effect of the polyphcnol compound~ extracted from green teu
(Camellia Sinesis L.) on alloxan induced diabetic l"dbbils to detennine their role in
treaunent of diabete> mellitus. their effect on enzymatic antioxidant and to kno" the
histological effects on the diabetic kidney. The rabbits group was divided into fhe
groups. each group consist of I 0 rabbits. The blood and thsue samples from these
