Abstract

The in vivo protective role of hydro-methanolic root extract of Withania somnifera (WS) was evaluated in alleviating lead nitrate (LN)-induced toxicity in male Swiss albino mice by measuring hematoserological profiles. The lead-treated (20 mg/kg body wt, p.o.) albino mice (25-30 g) concurrently received the root extract (200 and 500 mg/kg body wt, p.o.) once daily for the duration of six weeks. Animals exposed to LN showed significant (P < 0.001) decline in haemoglobin content, red blood cell count, white blood cell count, packed cell volume and insignificant decrease in mean corpuscular haemoglobin and mean corpuscular haemoglobin content, while mean corpuscular volume and platelet count were increased. A significant elevation (P < 0.001) in serum glutamate oxaloacetate transaminase, serum glutamate pyruvate transaminase, alkaline phosphatase, acid phosphatase and total cholesterol were also observed, when compared with control mice. Thus, the study demonstrated that the concurrent daily administration of root extract of WS protected the adverse effects of LN intoxication in mice.
