Cytotoxicity of the serum from rats exposed to chlorpyrifos (CPF). (A) Live cell number of Jurkat cells were determined after treated with serum prepared from the rats exposed to CPF at doses of 1.30 mg/kg/day (L), 3.26 mg/kg/day (M), and 8.15 mg/kg/day (H), respectively. (B) Viable cells were counted after Jurkat cells were treated with serum prepared from rats exposed to high dose of CPF (8.15 mg/kg/day). Abbreviations: FBS, fetal bovine serum. ^*P < 0.05 and ^**P < 0.01, compared with the control
