Lead is one of the most important environmental pollution which is toxic to many organ systems. D-penicillamine (D-P) is a chelator drug which is used for treatment of lead toxicity for several years. This study was conducted in order to evaluate the efficacy of D-P in reducing the effects of lead on hematological indices. This study was done on 36 male adult, 6-8 weeks albino Wistar rats in Gorgan University of Medical Sciences. At first male adult rats were exposed to lead acetate in their drinking water. After 8 weeks, 6 rats were selected and blood samples were prepared to assess the effects of lead toxicity. The remained lead exposed rats were divided into recovery and treatment groups where distilled water and D-P was administered for them, respectively. After lead exposure, red blood cell count increased slightly, but hemoglobin and hematocrite were decreased. Also MCV and MCH were significantly decreased (P<0.05). RDW, PDW and MPV were significantly higher in lead exposed rats (P<0.05). After recovery period, most of parameters were close to normal while there were no significant differences between recovery and treatment groups. This study showed that hematologic effects of lead are reversible and D-P administration do not play an important role in subchronic lead intoxication.
