ABSTRACT
Objective To explore whether the use of purified rabbit serum paraoxonase 1 (PON1) for the treatment of dichlorvos-induced liver injury in rats is superior to traditional method.Methods Thirty male SD rats were randomly divided into the followint 5 groups,with 6 rats in each groupcontrol group (A group),dichlorvos group (B group),traditional treatment group (C group),PON 1 treatment group (D group),combined treatment group (E group).Rats in groups B,C,D and E were adminstered dichlorvos by intraperitoneal injection 9 mg/kg.In group C,atropine 10 mg/kg and iodine solution 45 mg/kg were injected intraperitoneally within 2 min after dichlorvos administration.In group D,PON1 was injected intravenously at a dose of 9 600 U/kg,30 min prior to poisoning.In group E,PON1 was injected intravenously at a dose of 9 600 U/kg,30 min prior to poisoning,followed by in travenous injection of atropine 10 mg/kg and iodine solution 45 rng/kg within 2 min after poisoning.Rats in A group received normal saline.Blood was collected at different time points to examine the acetyl cholinesterase (AChE)-levels by ELISA method.Liver tissue were collected at 12 hours after model establishment to observe the pathological changes.The expression of 4 hydroxy 2-nonenal (4-HNE) in the liver tissue was detected by immunohistochemistry and Western blotting.Results In group B,AChE levels decreased significantly,liver cells showed severn fatty degeneration,karyopyknosis and other pathological changes,and 4-HNE expression increased.The pathological changes of group D and group E were less obvious than those of group C,and the 4-HNE expression in the group D and group E were significantly different from that in the group C (P< 0.05).Conclusion PON1 plays a protective role in dichlorvos-induced liver injury in rats,and this protection is better than that offered by traditional treatment.
