白花蛇舌草乙醇提取物对人肾癌细胞786-0体外增殖及小鼠肾癌细胞786-0移植瘤生长的影响
目的探讨白花蛇舌草乙醇提取物(EEHDH)对人肾癌786-0细胞体外增殖及小鼠肾癌细胞786-0移植瘤生长的影响。方法 (1)将人肾癌细胞786-0分为观察1、2、3、4组和对照组,观察1、2、3、4组分别加入终浓度为10、20、40、80 mg/L的EEHDH,对照组加入等体积培养液。培养24、48、72 h后采用MTT法于490 nm处测量吸光度值(OD490值)。(2)取42只昆明小鼠,随机分为7组,分别为模型组、EEHDH低剂量组、EEHDH中剂量组、EEHDH高剂量组、环磷酰胺组、EEHDH中剂量联合环磷酰胺组、对照组,每组6只。除对照组小鼠正常饲养不处理外,余36只小鼠每只左后肢腋...

| Summary: | 目的探讨白花蛇舌草乙醇提取物(EEHDH)对人肾癌786-0细胞体外增殖及小鼠肾癌细胞786-0移植瘤生长的影响。方法 (1)将人肾癌细胞786-0分为观察1、2、3、4组和对照组,观察1、2、3、4组分别加入终浓度为10、20、40、80 mg/L的EEHDH,对照组加入等体积培养液。培养24、48、72 h后采用MTT法于490 nm处测量吸光度值(OD490值)。(2)取42只昆明小鼠,随机分为7组,分别为模型组、EEHDH低剂量组、EEHDH中剂量组、EEHDH高剂量组、环磷酰胺组、EEHDH中剂量联合环磷酰胺组、对照组,每组6只。除对照组小鼠正常饲养不处理外,余36只小鼠每只左后肢腋窝皮下接种0.2 mL肿瘤细胞悬液,24 h后称重。模型组灌胃等体积饮用水14 d;EEHDH低、中、高剂量组分别灌胃EEHDH 5.0、10.0、20.0 g/kg,1次/d,共14 d;环磷酰胺组每2 d灌胃1次20 mg/kg环磷酰胺,共灌胃7次;EEHDH中剂量联合环磷酰胺组在1、3、5天灌胃环磷酰胺20 mg/kg,第6天开始灌胃10.0 g/kg的EEHDH,1次/d,共9次。末次给药24 h后给各组小鼠称重,处死动物称瘤重,计算EEHDH低剂量组、EEHDH中剂量组、EEHDH高剂量组、环磷酰胺组、EEHDH中剂量联合环磷酰胺组抑瘤率。另分离各组小鼠胸腺、脾脏,精密称重,计算胸腺指数、脾脏指数。结果 (1)相同培养时间条件下观察1、2、3、4组人肾癌细胞786-0的OD490值与对照组相比均较低(P均〈0.05)。人肾癌细胞786-0的OD490值随着培养时间的延长和EEHDH剂量的增加而降低(P均〈0.05)。(2)实验结束时,模型组、EEHDH低剂量组、EEHDH中剂量组、EEHDH高剂量组、环磷酰胺组、EEHDH中剂量联合环磷酰胺组瘤重分别为(2.31±0.28)、(1.94±0.22)、(1.59±0.26)、(1.52±0.23)、(0.92±0.24)、(0.86±0.23)g,EEHDH低剂量组、EEHDH中剂量组、EEHDH高剂量组、环磷酰胺组、EEHDH中剂量联合环磷酰胺组抑瘤率分别为16.02%、31.22%、34.26%、60.20%、62.77%。EEHDH中剂量联合环磷酰胺Q值为0.87。模型组小鼠胸腺指数、脾脏指数与对照组相比均较高(P均〈0.05)。环磷酰胺组小鼠胸腺指数、脾脏指数 |
