Abstract: Objective To investigate the effects of Lycopene(LP)on immune function of ovarian cancer rats' and its mechanism.Methods Sixty ovarian cancer rat models made by injecting ovarian cancer cell line NUTU-19 were divided into five groups randomly:model group,Cisplatin group(2 mg/kg)and LP(40,20,10 mg/kg)group,n=12;the LP and Cisplatin were given by intraperitoneal injection,once every two days for 5 times.The rats general states and tumor growth conditions were observed,the tumor tissue morphological changes was observed by H&E staining;the tumor weight,inhibition rate,spleen lymphocyte transformation rate were detected;and the content of IL-2 and TNF-α in serum were detected.The present of CD4+,CD8+ in blood were detected and the ratio of CD4+/CD8+ was calculated.Results The food situation of the rats in LP groups was improved,tumor was reduced,activity and hardness were poorer,necrosis presented,tumor cell shrinkage and other pathological morphological changes appeared,especially the rats in LP 40 mg/kg group.Compared with model group,the tumor weight in LP(40,20 mg/kg)groups was decreased,the inhibition rate and the spleen lymphocyte transformation rate were increased;the contents of IL-2 and TNF-α were decreased;the CD8+ present was decreased,while the CD4+ present in LP 40 mg/kg group was increased,the ratio of CD4+/CD8+ was increased.All of the difference above were significant(P<0.05,P<0.01).Conclusion LP can effectively improve the immune function of ovarian cancer rat;which perhaps relates to its effects of reducing the inflammatory cytokines levels and increasing the ratio of CD4+/CD8+.
