Effect of Ficus carica extract on hematological parameters and antioxidant defense system in erythrocytes of albino rats exposed to nickel chloride

Heavy metals including nickel have adverse effects on hematological system and red blood cells antioxidant defense. The purpose of the study is to examine the possible corrective effect of fig (Ficus carica L.) extract (FCE) on hematological parameters and antioxidant enzyme activities in red blood cells of rats exposed to sub-lethal concentration of nickel. Male Wistar rats were exposed to nickel chloride (10 mg/kg) and then treated or no with FCE (350 mg/kg) for 4-weeks. The intoxication induces alteration of haematological parameters and enhances blood haemolysis, generates oxidative stress induced decrease in the antioxidant enzyme activities and depletion in reduced glutathione levels in intoxicated group compared to the control group. The oral administration of FCE increase significantly hemoglobin levels (Hb), red blood cells count (RBC), hematocrit (Ht) and decreases white blood cells counts (WBC), and platelets in F. carica treated groups, and also the extract increase the GSH-Px and SOD antioxidant activity, GSH reserves in red blood cells, and reduces lipids peroxidation. The present study concludes that fig fruits may exhibit potent antioxidant potential for erythrocytes and have a positive effect on hematological system.
