Objectives : The object of this study was to observe anticancer and immunomodulatory effects of Formosa plum aqueous extracts (PLe) on non-small cell lung carcinoma (squamous epithelial carcinoma), NCI-H520, xenograft Balb/c nu-nu nude mice. Method : Three different dosages of PLe, 50, 100 and 200 mg/kg were orally administered once a day for 28 days from 11 days after tumor cell inoculation. Five groups, each of seven mice per group were used in the present study as follows. Tumor volume and weights, serum interferon (IFN)-γ levels, serum IL-6 were observed with tumor mass and lymphatic organ histopathology to detect anticancer and immunomodulatory effects. Result : Although no meaningful changes on the tumor weights and volumes were observed after treatment of all three different dosages of PLe, decreases of tumor cell volumes in tumor masses were dose-dependently decreased mediated by increases of apoptosis among tumor cells by treatment of PLe 100 and 200 mg/kg as compared with tumor-bearing control. In addition, decreases on the body weight and gains were also demonstrated in tumor-bearing control with increases of serum IL-6 levels. Conclusion : The results obtained in this study suggest that over 50 mg/kg of PLe showed favorable immunomodulatory and anticachexic effects with anticancer effects in 100 and 200 mg/kg of PLe treated groups 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.

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.

The object of this study was to observe anticancer and related immunomodulatory and anticachexic effects of Insamyangyoung-tang aqueous extracts (ISYYTe) on non-small cell lung carcinoma (squamous epithelial carcinoma), NCI-H520, xenograft Balb/c nu-nu nude mice. Changes on the tumor volume and weights, lymphatic organ(spleen and popliteal lymph node), serum interferon (IFN)-${\gamma}$ levels, splenocytes and peritoneal macrophage activities (NK cell activity), splenic tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$ and IL-10 contents, splenic T-lymphocyte subsets (CD3+, CD4+ and CD8+) and TNF-${\alpha}+$ cells were observed with tumor mass and lymphatic organ histopathology to detect anticancer and immunomodulatory effects. In addition, changes on the body weights, epididymal fat weights and serum IL-6 levels were also detected with the thicknesses of deposited cervical brown adipose tissue and their mean diameters to monitor the tumor-related anticachexic effects. The results obtained in this study suggest that over 50 mg/kg of ISYYTe showed favorable anticancer effects on the NCI-H520 cell xenograft with immunomodulatory and anticachexic effects. However, detail mechanism studies should be conducted in future with the screening of the biological active compounds in this herb.

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.

Methods : Three different dosages of ISYYTe, 50, 100 and 200 mg/kg were orally administered once a day for 42 days from 11 days after tumor cell inoculation. Six groups, which are intact control, tumor bearing control, 5-fluorouracil (FU) 30 mg/kg, ISYYTe 50 mg/kg, ISYYTe 100 mg/kg, ISYYTe 200 mg/kg, each of 8 mice per group were used in the present study. Changes on the body weight, tumor volume and weight, lymphatic organ (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. Results : As results of ISYYTe 50, 100 and 200 mg/kg treatment, decreases in the tumor volumes and weights were detected. At histopathological observations, decreases of tumor cell volumes in tumor masses were dose-dependently decreased mediated by increases of apoptosis among tumor cells by treatment of all three different dosages of ISYYTe. As results of tumor cell inoculation, marked decreases of spleen and popliteal lymph node weights, serum IFN-${\gamma}$, splenic TNF-${\alpha}$, IL-$1{\beta}$ and IL-10 contents and splenocytes were observed with histopathological atrophic changes of spleen and popliteal lymph nodes. Conclusions : Over 50 mg/kg of ISYYTe showed favorable anticancer effects on the NCI-H520 cell xenograft with immunomodulatory effects. Although relatively lower anticancer effects were observed in ISYYTe 200 mg/kg treated mice as compared with 5-FU 30 mg/kg treated mice, there are no meaningful favorable immunomodulatory effects were observed after 5-FU treatment in the present study.

Heptaplatin, cis-malonato [(4R,5R)-4,5-bis (amino-methyl)-2-isopropyl-1,3-dioxolane] platinum(II) (SKI-2053R, Sunpla) is a new platinum derivative with antitumor activity comparable to cisplatin on various cancer cell lines. Preclinical studies suggest that it is less nephrotoxic than cisplatin. This study was undertaken to examine the combined effect of heptaplatin and ionizing radiation on two established human squamous carcinoma cell lines (NCI-H520, SQ20B). The cytotoxic activity of heptaplatin was concentration-dependent in both cell lines. When low dose heptaplatin was combined with high dose ionizing radiation, there was an additive cytotoxic effect on NCI-H520 cells (P < 0.05), while a moderate dose of heptaplatin and a low dose of ionizing radiation had an additive cytotoxic effect on the growth of SQ20B cells (P < 0.05). FACS analysis and DAPI staining showed that their additive cytotoxic effects were correlated with the induction of apoptosis. Further studies are warranted using heptaplatin and ionizing radiation in squamous cell carcinoma as a substitute for cisplatin.
