The aim of this study is to investigate the probable effects of Tinnas  grewia extract (TGE)  on complete blood cells and serum antioxidant enzymes level in rats by the dose of (2,4,6 and 8ml orally/day). Thirty 30 male albino rats about (150±10g) were used in this study, and then divided into five equal groups each (6 rats). The first one considers a control negative group that fed on a basal diet all the time during the experiment, the other groups (24 rats) were fed on a stander diet + the Oral doses of TGE for (4 weeks). Complete blood cells count levels (HB, HCT, RBCs and PLT ) showed significant increases compared with the negative control group. WBCs showed a decrease. For antioxidant enzymes (SOD, CAT, GSH and GPx) were significantly increase comparing with control (-ve).
