岩舒注射液对荷瘤小鼠化疗增效减毒及免疫功能的影响

目的研究岩舒注射液对荷瘤小鼠化疗增效、减毒及免疫调节作用。方法制作小鼠肉瘤-180(S180)腹水瘤转实体瘤模型,观察岩舒注射液与环磷酰胺(Cy)合用对瘤体重量、血液白细胞(WBC)数、骨髓有核细胞数的影响;采用分光光度比色法测定溶血空斑OD值、3H-胸腺嘧啶(3H-TDR)掺入法测定T淋巴细胞转化、比色法测定自然杀伤细胞(NKC)活性,观察岩舒注射液对荷瘤小鼠免疫功能的影响。结果岩舒注射液能增强Cy抑瘤作用、拮抗Cy对WBC及骨髓有核细胞的抑制;提高溶血空斑OD值、促进T淋巴细胞转化、增强NKC活性及杀伤率。结论岩舒注射液对荷瘤小鼠具有化疗增效、减毒及免疫增强的作用。

Study of Yanshu Injection on Enhancing Effects of Chemotherapy and Reducing Toxicity and Immune Effect in Tumor-bearing Mice

Objective To investigate the effects of Yanshu injection for the chemotherapy, toxicity- reducing and immunization in mice implanted tumor. Methods Bulid up the mice models with S180 solid tumor transfered by ascites tumor, and observe the effect on tumor weight, blood WBC and bone marrow nucleated cells when combined use Yanshu injection and cyclophospamide (Cy). Determine OD value of plague forming cell by spectrophotometry, measure T-lymphocyte transformation by 3H-TDR incorporation, and survey natural killer cell (NKC) activity by colorimetric method, all these can help to study the role of Yanshu injection on the immune effect in the mice models. Results Yanshu injection can strengthen antitumor activity of Cy, antagonize the inhibition of Cy to WBC and bone marrow nucleated cell, improve OD value of plague forming cell, promote T-lymphocyte transformation, also can enhance NKC activity and killing rate. Conclusion Yanshu injection can increase the chemotherapeutic effects, reduce toxin, and enhance immune function of mice implanted tumor.
