Objectives : This study was to observe anticancer and related immunomodulatory effects of Kwibi-tang extracts (KBTe) on non-small cell lung carcinoma (squamous epithelial carcinoma), NCI-H520, xenograft Balb/c nu-nu nude mice. Methods : Three different dosages of KBTe, 50, 100 and 200 mg/kg were orally administered once a day for 42 days from 11 days after tumor cell inoculation. Six groups, each of 8 mice per group were used in the present study. Changes in body weight, tumor volume and weight, lymphatic organs (spleen and popliteal lymph node), serum interferon (IFN)-${\gamma}$ levels, splenocytes NK cell activity and peritoneal macrophage activities, splenic tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$ and IL-10 contents were observed with tumor mass and lymphatic organ histopathology to detect anticancer and immunomodulatory effects. The results were compared with a potent cytotoxic anticancer agent, 5-FU (5-Fluorouracil) 30 mg/kg, intraperitoneal treatment (3-day intervals for 42 days, the optimal effective treatment regimes already confirmed). Results & Conclusions : This study suggest that over 50 mg/kg of KBTe showed favorable anticancer effects on the NCI-H520 cell xenograft with immunomodulatory effects. Although relatively lower anticancer effects were observed in KBTe 200 mg/kg treated mice as compared with 5-FU 30 mg/kg treated mice, no meaningful favorable immunomodulatory effects were observed after 5-FU treatment in the present study.

Purpose : The object of this study was to observe anti-cachexic effects of Kwibi-tang extracts (KBTe) on non-small cell lung carcinoma (squamous epithelial carcinoma), NCI-H520, xenograft Balb/c nu-nu nude mice. Methods : Three different dosages of KBTe, 50, 100 and 200 mg/kg were orally administered once a day for 42 days from 11 days after tumor cell inoculation. Six groups, each of 8 mice per group were used in the present study. Changes on the body weight, the epididymal fat weight and serum IL-6 levels were detected with the thicknesses of deposited cervical brown adipose tissue and their mean diameters to monitor the tumor-related anticachexic effects. Results : Deceases on the body weight and gains were also demonstrated in tumor-bearing control with increases of serum IL-6 levels, decreases of epididymal fat pad weight, atrophic changes of cervical brown adipose tissues. These are means that tumor-related cachexia are induced by tumor cell inoculations in the present study. However, these tumor-related cachexia were markedly inhibited by all three different dosages of KBTe treatment as compared with tumor-bearing control. 5-FU showed somewhat deteriorated the tumor-related cachexia in the present study. Conclusion : The results obtained in this study suggest that over 50 mg/kg of KBTe showed favorable anticachexic effects on the NCI-H520 cell xenograft. However, detail mechanism studies should be conducted in future with the screening of the biological active compounds in this herb.
