摘 要 应用流式细胞光度分析法测定丹参和川芎嗪对体外培养的瘢痕成纤维细胞DNA相对含量和细胞周期时相变化，发现药物在一定浓度作用下，DNA指数无明显变化；丹参使C2-M期细胞分布增多，G2-M期延长；川芎嗪使G2-M期细胞分布增多，G2-M期、S期延长；药物使细胞群体倍增时间延长，与浓度呈明显直线正相关。

Hydrochloric acid and thiosulphate solution react to give sulphur particles which can block the transmission of light. Under this merit, light sensor can be used to collect the corresponding experimental data. Analysing these data can help to find out the relationship between the concentration of solution and the rate of reaction.
