Protective effect of Nigella sativa seeds against lead-induced hepatorenal damage in male rats.

Heavy metals are widely distributed in the environment and some of them occur in food, water, air and tissues even in the absence of occupational exposure. Among of these lead, (Pb) is a hazardous substance to human and animals. The present study was carried out to investigate the possible protective effect of co-administered Nigella sativa seeds on lead acetate-induced rats' toxicity in particularly on liver and kidney.
