摘要: 本文研究了菹草类胡萝卜素(CEPC)的抗癌作用及其对免疫功能的影响。以动物移植性肿瘤小鼠肝癌H22为模型,以环磷酰胺为阳性对照,以色拉油为阴性对照,观察5、10、20mg/kg·d的CEPC的体内抗肿瘤作用及其对荷瘤小鼠肝脏中MDA、SOD的影响,通过CEPC对二硝基氟苯(DNFB)诱导的迟发型变态反应(DTH),对淋巴细胞增殖反应的作用和NK细胞活性的测定来观察其对免疫系统的影响。结果表明低中高浓度的CEPC与阴性对照组相比对肝癌H22瘤细胞均有较强的杀伤力,对荷瘤小鼠肝脏中MDA有降低作用,对SOD有增强作用,且CEPC对小鼠免疫系统具有较强的激活作用。提示CEPC对移植性H22肿瘤小鼠具有抗肿瘤作用,并对免疫功能有调节作用。

Abstract: The antitumor activity and immune function of carotenoids from Potamogeton crispus L. (CEPC) were studied in thisarticle. Cyclophosphamide was the positive control and salad oil the negative control. H22-bearing mice were used as animalmodels. The changes of H22 tumor weight in vivo, the changes of MDA and SOD of liver in H22-bearing mice and the effect onimmune system such as DTH induced by DNFB, proliferation of lymphocytes and NK activity were investigated when differentdosage CEPC (5, 10, 20mg/kg·d) were used. It was shown that CEPC markedly inhibited tumor growth in the H22-bearing mice.It could also decrease MDA and increase SOD of liver in the H22-bearing mice. CEPC enhanced the immune function. So CEPChas both the antitumor effect and the immunity effect modulation.
