摘要

Increased use of pesticides has resulted in environmental contamination and their residues ill most food stuffs. The continuous retake of low levels of pesticides by man and animals may lead to various deleterious effects in body. To assess the effect of lindane on cell mediated immune response ill sheep, eight six-month old lambs were taken and randomly divided in two groups of four lambs each. These lambs were vaccinated with Brucella melitensis rev. 1 at day zero and day 90. One group was given lindane daily orally at dose rate of 1.25 mg/kg body weight for six months. The lymphocyte stimulation test, total leucocyte count and absolute lymphocyte count were performed from blood collected at 10 days interval. Delayed type hypersensitivity (DTH) reaction was assessed at six months of observation. A highly significant suppression m total leucocyte count, absolute lymphocyte count, lymphocyte stimulation test and DTH reaction was observed ill lindane-fed lambs as compared to controls, which indicated the suppression of cell mediated immune response in sheep fed lindane at 'no adverse effect doses'.
