摘　　要：为确定中药复方921粗提物的抗前列腺癌作用,采用SRB法考察921方粗提物对肿瘤细胞株的体外生长抑制作用,采用小鼠可移植瘤模型肝癌H22、肉瘤S180、前列腺癌TRAMP-C2和人前列腺癌细胞PC-3M裸鼠移植模型,考察其对体内肿瘤的生长抑制作用,并了解其与CTX合用时的增效和减毒作用。结果显示：1）921方粗提物对DU-145,PC-3M,EJ,TRAMP-C2等细胞株的GI50约在1∶14.2～1∶73.5（稀释度）之间;2）对肝癌H22小鼠移植瘤的抑制率达42%,对肉瘤S180小鼠移植瘤的抑制率达52%,对TRAMP-C2小鼠移植瘤的抑制率达36%,对人前列腺癌细胞PC-3M裸鼠移植瘤的抑制率达44.2%,与CTX合用能起到协同抗肿瘤作用并且不增加毒性。结果表明中药复方921粗提物具有一定的抗前列腺癌作用。In order to investigate the inhibition of the extracts of prescription of 921 on prostate cancer cell proliferation in vitro and tumor growth in vivo, the authors used the methods as follows ： SRB assay was applied to examine the anti-proliferation of the extracts of prescription of 921 in vitro both on human cancer cell DU-145, PC-3m, EJ and mice prostate cancer TRAMP-C2. The experimental implanted tumor mice model Hepatoma （H22）, Sarcoma （S180）, Prostate cancer （TRAMP-C2） and tumor nude mice model Prostate cancer （PC-3M） were used to evaluate its anti-tumor activity in vivo. Furthermore, the enhance therapeutic effect was also observed when combined with cyclophosphamide （CTX） on S180. The results were 1 ） the extracts of prescription of 921 showed proliferation inhibitory activities on DU-145, PC-3M, EJ and TRAMP-C2 cell lines; 2） it inhibited mice H22, S180, TRAMP-C2 and naked mice PC-3M when administered i.g. at 3.6- 14.3 g/（kg·day） for 9 days. The extracts of prescription of 921 enhanced CTX＇s therapeutic effect and didn＇t enhance its toxicity. In summary, the extracts of prescription of 921 showed inhibitory activity on the growth of prostate cancer.
