Objectives : To evaluate the anti-tumor and synergic effect of Soonkiwhajungtang with doxorubicin. Methods : The inhibitory concentration (IC), $IC_{50}$ and $IC_{90}$ of single use of doxorubicin and Soonkiwhajungtang with their concomitant treatment against MKN-45 (human stomach carcinoma) cell line were observed using MTT (microculture tetrazolium test) assay. In addition, their anti-tumor effects were also observed in xenograft nude mice models against the MKN-45 cell line. Results : Soonkiwhajungtang has only minimal direct anti-tumor effect against MKN-45 cell line but it reduced general depressed signs induced by implantation of the tumor cell lines and increased the total WBC and lymphocyte numbers. Conclusions : It is considered or expected that Soonkiwhajungtang extract reduces the critical toxicity of doxorubicin and has favorable synergic anti-tumor effect when administered concomitantly with doxorubicin.

In order to evaluate the anti-tumor and synergic effect of Soonkiwhajungtang with doxorubicin, the inhibitory concentration(IC), $IC_{50}\;and\;IC_{90}$ of single use of doxorubicin and Soonkiwhajungtang with their concomitant treatment against Colon-26(Murine Rectum Carcinoma) was observed using MTT(Microculture Tetrazolium test) assay. In addition, their anti-tumor effects were also observed in the xenograft nude mice models agianst to Colon-26 cell lines. Soonkiwhajungtang has only mimic direct anti-tumor effect against to Colon-26 cell lines but they were decreased general depressed signs induced by implantation of tumor cell lines and increased the total WBC and lymphocyte numbers. So, it is considered or expected that Soonkiwhajungtang extracts were reduced the critical toxicity of doxorubicin and shows favorable synergic effect with doxorubidn and Soonkiwhajungtang extracts.

In order to evaluate the anti-tumor and synergic effect of Soonkiwhajungtang with doxorubicin, the inhibitory concentration(IC), IC50 and IC90 of single use of doxorubicin and Soonkiwhajungtang with their concomitant treatment against Colon-26(Murine Rectum Carcinoma) was observed using MTT(Microculture Tetrazolium test) assay. In addition, their anti-tumor effects were also observed in the xenograft nude mice models against 3LL cell lines. Soonkiwhajungtang may only mimic direct anti-tumor effects against 3LL cell lines, but signs of worsening induced by implantation of tumor cell lines generally decreased, while the total WBC and lymphocyte numbers increased. Therefore, experimentation suggests that Soonkiwhajungtang extracts reduced the critical toxicity of doxorubicin, and that Soonkiwhajungtang extracts have favorable synergic effects when combined with doxorubicin.
