摘要: 目的 研究番茄红素(LP)改善荷卵巢癌大鼠免疫功能的作用并探讨其机制。方法 将卵巢癌细胞NUTU-19接种于腋窝皮下,制备荷卵巢癌大鼠模型,取60只模型大鼠随机分为模型组、顺铂组(2 mg/kg)和LP(40、20、10 mg/kg)组,每组12只;各治疗组均隔天腹腔注射给药一次,共5次。观察各组大鼠一般生存状态和肿瘤生长状况;称量肿瘤重量并计算抑瘤率,通过HE染色观察肿瘤组织形态结构变化;噻唑蓝(MTT)比色法测定脾淋巴细胞转化率;酶联免疫(ELISA)法测定血清中白细胞介素-2(IL-2)和肿瘤坏死因子-α(TNF-α)含量;流式细胞仪术(Flow cytometry)检测血中T淋巴细胞亚群(CD4+、CD8+)百分率并计算CD4+/CD8+结果 与模型组比较,发现LP各组大鼠饮食状况好转,瘤体减小、活动度和硬度较差,肿瘤组织细胞皱缩、呈片状坏死等病变,上述改变以LP 40 mg/kg组最为显著;LP(40、20 mg/kg)组瘤重显著减轻且抑瘤率显著升高(P<0.05,P<0.01),脾淋巴细胞转化率显著升高(P<0.05,P<0.01),血清中IL-2和TNF-α含量均显著降低(P<0.05,P<0.01),血液中CD8+百分率显著降低(P<0.05,P<0.01),LP 40 mg/kg组CD4+百分率显著升高(P<0.05),LP(40、20 mg/kg)组CD4+/CD8+显著升高(P<0.05,P<0.01)。结论 LP具有提高荷卵巢癌大鼠免疫功能的作用,其机制可能与LP能够有效降低炎症细胞因子(IL-2、TNF-α)含量以及提高CD4+/CD8+比值有关。

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+.
