芪升合剂对S180荷瘤小鼠化疗的减毒增效研究

目的观察芪升合剂对S180荷瘤小鼠化疗所致骨髓抑制的干预作用。方法将60只小鼠随机分成正常对照组、荷瘤对照组、环磷酰胺（CTX）组及芪升合剂高、中、低剂量。除正常对照组外,其余各组将S180瘤细胞接种于小鼠右前肢腋窝皮下。各给药组于接种后第1日分别灌胃相应药物,连续给药10 d;接种第4日各给药组分别腹腔注射CTX,连续3 d;正常对照组和荷瘤对照组予生理盐水灌胃。观察各组外周血常规、瘤质量、抑瘤率。结果芪升合剂可明显提高S180荷瘤小鼠化疗后白细胞数量,与CTX组比较差异有统计学意义（P〈0.01）;CTX组、芪升合剂各剂量组血小板计数明显降低,与荷瘤对照组比较差异有统计学意义（P〈0.05）。荷瘤对照组肿瘤生长迅速,CTX组、芪升合剂各剂量组瘤质量明显小于荷瘤对照组（P〈0.01）;与CTX组瘤质量相比,中剂量组差异有统计学意义（P〈0.01）。CTX对荷瘤小鼠肿瘤生长有明显抑制作用,其抑瘤率达49.69%,联合芪升合剂后,高、中、低剂量抑瘤率可达60.55%、72.11%、64.48%。结论芪升合剂对S180荷瘤小鼠的化疗具有增效减毒作用。

Anti-tumor Effect of Qishengheji and Its Influence on Myelosuppression Caused by Chemotherapy in S180 Tumor-bearing Mice

Objective To observe the effect of Qishengheji on myelosuppression caused by chemotherapy in S180 tumor-bearing mice.Methods Sixty mice were randomly divided into six groups,including normal control group,S180 control group,Cyclophosphamide(CTX) group,and high,medium and low dose of Qishengheji group.All mice except normal control group were vaccinated with S180 cells in armit of the right forearm,and administrated with corresponding drugs for 10 days.The administration groups were injected CTX intraperiton...
