芦荟提取物C对小鼠移植性肿瘤及免疫功能的影响

目的 :研究芦荟提取物C(AloeExtractC ,AE C)对小鼠移植性肿瘤 (实体瘤 )的抑制作用和其对脾细胞IL 2分泌活性及NK细胞杀伤活性的影响。方法 :建立AE C的提取和主要成分含量测定法。用S180和MethA移植瘤动物模型为研究对象 ,经腹腔注射AE C后 ,观察肿瘤组织的病理学改变并检测其脾细胞IL 2分泌活性和NK细胞杀伤活性。结果 :AE C能促使肿瘤组织大面积出血坏死及炎细胞浸润 ,按瘤组织坏死和炎细胞胞浸润分级积分法记录 ,AE C治疗组明显高于对照组和 5 FU治疗组 (P <0 .0 1)。脾细胞IL 2分泌活性S180 移植瘤AE C治疗组与其对照组比较升高 4 2 .6 % ,MethA移植瘤AE C治疗组与其对照组比较升高 6 2 .6 %。NK细胞杀伤活性AE C治疗组较对照组有明显的升高 (P <0 .0 1)。 5 FU治疗组小鼠免疫功能明显受到抑制。结论 :AE C有抑制肿瘤和调节机体免疫功能的作用。

Effect of Aloe Extract C for Parenchymatous Tumor and Immune Function in Mice

Objective We studied the effect of AE C(Aloe Extract C)for parenchymatous tumor and immunity function in mice.Methods To build extraction and examination of AE C,mice S 180 and Meth A parenchymatous tumor are treated by injection AE C into abdominal cavity.The pathological diagnosis of tumor tissue and examination on activity of IL 2 and NK cell are used to judge the effect of AE C.Results The AE C an prompt tumor tissue large area necrosis and inflammation cellincursion.To compare with negative it is obvious to inhibition tumor growth and to increase spleen cell function of secretion IL 2 and nature kill.Conclusions AE C from aloe take effect on inhibition tumor growth and immunoregultion.
