The third group was exposed to 6 Gy (irradiated control group).

The fourth, fifth, and the last groups were treated by three doses of I.V.E.

(200, 400, and 800 mg/kg.b.wt.mice) interaperitonealy, then exposed to 6 Gy.

Results: In irradiated group, for the most biochemical parameters, irradiation induced significant changes in hematopoietic parameters, body weight, and stress oxidative markers of organ functions like (LPO and GSH).

Liver enzymes were elevated significantly compared with control group.
