파두가대황(巴豆加大黃)이 항종양작용(抗腫瘍作用)과 자연살해세포(自然殺害細胞)의 활성(活性)에 미치는 영향에 대한 실험적 연구

This experiment was designed to study the antitumor effects and Activity of Natural Killer Cell of semen Tiglii plus Rhizoma Rhei. The cytotoxic and antitumor effects were evaluated on human cell lines(A549, Caki-1, LL2, Sarcoma 180, NIH/3T3) after exposure to prebrewed Semen Tiglii plus Rhizoma Rhei water extract 0.1, 0.2, 0.4, 0.8, 1.6mg/ml using in MTT assay, LDH, colony forming efficency and SRB assay which were regarded as a valuable method for cytotoxic and antitumor effects of unknown compound on tumor cell lines. The results obtained in this studies were as follows. 1. From the result of MTT assay, the cytotoxicity of ST(生巴豆霜), ST+RR(生巴豆霜加大黃) were concentration-dependently increased in both group of the ST and ST+RR, the cytotoxicity of ST+RR(生巴豆霜加大黃) was similar to that of ST(生巴豆霜). 2. From the result of LDH, the cytotoxicity of ST, ST +RR were concentrati -on-dependently increased in both group of the ST and ST+RR, the cytotoxicity of ST+RR was similar to that of ST. 3. The antitumor effect on A549 tumor cell from the result of colony forming efficiency showed the inhibitory effect on the growth in both group of the ST and ST+RR, the inhibitory effect on growth was low slightly in the ST+RR. 4. From the result of SRB assay, the antitumor effect on caki-1 tumor cell of ST, ST+RR showed the inhibitory effect on the growth in both group of the ST and ST+RR, the antitumor effect of ST+RR was similar to that of ST. 5. Median survival time and increased life span were increased slightly in both group of the ST and ST+RR. 6. The inhibitory effect on the growth of Sarcoma 180 and Lewis lung carcinoma tumor cell were increased slightly in both group of the ST and ST+RR. 7. The activity of NK cell was increased in the ST+RR.
