ABSTRACT
Objective To study the effects of tri-ortho-cresyl phosphate(TOCP) on mitochondrial membrane permeability in hen's nerve tissues and investigate the mechanism of the organophosphorus ester-induced delayed neurotoxicity(OPIDN).Methods Adult Roman hens were randomly divided into four groups,including three treated groups and one control group(24 in each group).The hens in the experimental groups were treated with TOCP by gavage at the single dosages of 185,375 and 750 mg/kg respectively.TOCP was dissolved in corn oil and administered at 0.65 ml/kg.The control hens received an equivalent volume of corn oil by gavage.The hens were sacrificed on the 1st,5th,15th and 21st day after treatment and the cerebrum,cerebellum,spinal cord were dissected and homogenized in ice bath.The mitochondria in these nerve tissues were extracted to determine the changes of the membrane permeability and membrane potential.Results Compared with the control group,no significant increase of the mitochondrial membrane permeability in the cerebrum was observed in treated groups.In the cerebellum,the membrane permeability in the 185 mg/kg group had no significant changes,while in the 375 and 750 mg/kg groups it increased significantly on the 1st and 5th day after TOCP treatment(P
