| 中文摘要: |
| 目的 :对比研究中药复方白龙与西药诱导分化剂环六亚甲基双已酰胺 (Hexamethylenbisace lamide,HMBA)对人胃癌MGC80 3不同周期细胞的生长与表型调节的共性作用。方法 :采用高压笑气加胸腺嘧啶脱氧 (TdR)双阻断法将MGC80 3细胞分别同步于G1、S、G2 、M 4个时相 ,用中药复方白龙和HMBA分别处理各时相细胞。结果 :实验结果表明中药白龙或HMBA对MGC80 3不同周期细胞具有显著的增殖抑制作用 ,抑制率达 4 6 2 %～ 75 3%。细胞在软琼脂上的生长势态和细胞周期中的增殖抑制相似 ,但在S与G2 期中中药白龙的作用优于HMBA。与此同时细胞质微丝组装 ,除M期外 ,均显著增加。结论 :中药白龙与HMBA对人胃癌MGC80 3各时相细胞的生长与分化表型作用具有明显的共性特征 ,为促进中西医结合提供理论认识基础。 |
| 英文摘要: |
| Objective: To investigate and compare the common effect of Bailong, a Chinese herbal preparation, and Hexamethylene bisacetamide (HMBA), a western cell differentiation inducer, on growth regulation and phenotype of human gastric cancer (MGC80 3) cells in different phases of cell cycle. Methods: Synchronized MGC80 3 cells in monolayer cultures with nitrous oxide under high pressure were double blocked with overdosage of TdR in the 4 cellular phases (G 1, S, G 2 and M), and then collected and treated with Bailong and 5 mmol/L HMBA respectively. Results: Both medicines could suppress the cell proliferation, soft agar cloning growth and microfilament assembling of different phases of cells, the effect on cells of G 1 phase was the most significant one. Conclusion: Bailong and HMBA had significant common characteristics in inducing cell differentiation of MGC80 3 cells in different phases of cell cycle. |
