Abstract:
Objective To study the protective effect of polyene phosphatidylcholine on hepatic injury induced by oxaliplatin and 5?fluorouracil. Methods A subcutaneous tumor model was established by transplanting colocarcinoma HCT116 cells into 30 nude mice,which were random?ized into three groups. The polyene phosphatidylcholine group was injected with polyene phosphatidylcholine(85 mg · kg-1 · d-1)and 5?fluorouracil (20 mg·kg-1·d-1)for 7 days,and then injected with oxaliplatin(6 mg·kg-1·d-1)for 1 day. The hepatic injury group was injected with 5?fluoroura?cil(20 mg·kg-1·d-1)for 7 days and oxaliplatin(6 mg·kg-1·d-1)for 1 day. The tumor?bearing blank group was injected with normal saline. Hepat?ic injury was observed with ultrathin pathological sections. Liver homogenates were prepared to detect superoxide dismutase(SOD)and catalase (CAT)activity. Results In the hepatic injury group,pathological sections revealed dissolved cellular cytoplasm,mitochondrial membrane dam?age,cell membrane edema,and fuzzy,sinusoidal cell expansion . There were no obvious hepatic injuries observed in the polyene phosphatidylcho?line group. The expression of SOD and CAT were lower in the hepatic injury and polyene phosphatidylcholine groups compared to the tumor?bear?ing blank group(P<0.05). The expression of SOD and CAT were higher in the polyene phosphatidylcholine group compared to the hepatic injury group(P<0.05). Conclusion Polyene phosphatidylcholine has a protective effect on hepatic injury induced by oxaliplatin and 5?fluorouracil, which may be related to its effect on membrane repair and inhibition of oxidative stress.
