In order to investigate the effects of Gamihagochosan Extract(加味夏枯草散抽出液) on antitumor effects after human cell lines (A549, hep3B, Caki-1, Ehrlich) transplantation into the peritoneal cavity or right groin in mice induced by RPMI1640 and GIBCO etc., the extracts of its herbal medicines were orally administered for 10 or 12 days. Experimental studies were performed for measurement of antitumor effect of Mitomycin C(MMC) and lysosomal enzyme's activities using colony forming efficiency, SRB assay which were regarded as a valuable method for the measurement of antitumor effects of unknown compound on tumor cell lines. The results obtained in this studies were as follows : 1. The change of colony-forming efficiency and SRB assay of Caki-1 cells, hep3B and A549 Cells after exposure to the extract of Gamihagochosan extract depressed the growth of tumor cells by concentration of Garnihagochosan. 2. Antitumor activity of the ethanol extract from Gamihggochosan extract and MMC on ascites form of Ehrlich carcinoma in mice is slightly improved. Especially the mean of survival times in the group of 200mg/kg and MMC 0.1mg/kg is improved over 34.9%. 3. When Gamihggochosan extract and MMC are administered together, the weight of tumor is more decreased than MMC alone. 4. The lysosomal enzyme's activities of the Gamihagochosan extract and MMC are more significantly improved than MMC alone. According to the above result, it could be suggested that Gamihagochosan extract has indirect antitumor effect by the increase of MMC uptake.

In order to investigate the effects of Soyosangamibang Extract(逍遙散加味方抽出液) on antitumor effects after human cell lines(A549, hep3B, Caki-1, Ehrlich) transplantation into the peritoneal cavity or right groin in mice induced by RPMI1640 and GIBCO etc., the extracts of its herbal medicines were orally administered for 10 or 12 days. Experimental studies were performed for measurance of antitumor effect of MMC(Mitomycin C) and lysosomal enzyme's activities using colony forming efficency, SRB assay which were regarded as a valuable method for antitumor effects of unknown compound on tumor cell lines. The results obtained in this studies were as follows: 1. The change of colony-forming efficiency and SRB assay of Caki-1 cells, hep3B and A549 cells after exposure to the extract of Soyosangamibang extract depressed the growth of tumor cells by concentration of Soyosangamibang, 2. Antitumor activity of the ethanol extract from Soyosangamibang extract and MMC on ascites form of Ehrlich carcinoma in mice is a little improved. Especially mean survival times of the group of 200mg/kg and MMC 0.1mg/kg is improved Over 50%. 3. WhenSoyosangamibang extract and MMC are administrated together, the weight of turnor is more decreased than MMC alone. 4. The lysosomal enzyme's activities of the Soyosangarmibang extract and MMC are more significantly improved than MMC alone. According to the above results, it could be suggested that Soyosangamibang extract has indirect antitumor effect by strengthen the effect of MMC.

The present study was conducted to evaluate in vivo anticancer activity of two novel mononuclear ruthenium(II) compounds, namely Ru(1,10-phenanthroline)$_2$(2-nitro phenyl thiosemicarbazone)$Cl_2$(Compound $R_1$) and Ru (1,10-phenanthroline)$_2$(2-hydroxy phenyl thiosemicarbazone)$Cl_2$(Compound $R_2$) against Ehrlich ascites carcinoma (EAC) mice and in vitro cytotoxic activity against IEC-6 (small intestine) cell lines and Artemia salina nauplii using MTT [(3-(4,5-dimethylthiazol-2yl)-2,5-diphenyltetrazolium bromide)] and BLT [brine shrimp lethality] assays respectively. The tested ruthenium compounds at the doses 2 and 4 mg/kg body weight showed promising biological activity especially in decreasing the tumor volume, viable ascites cell counts and body weights. These compounds prolonged the life span (% ILS), mean survival time (MST) of mice bearing-EAC tumor. The results for in vitro cytotoxicity against IEC-6 cells showed the ruthenium compound $R_2$ to have significant cytotoxic activity with a $IC_{50}$ value of $20.0{\mu}g/mL$ than $R_1$ ($IC_{50}=78.8{\mu}g/mL$) in the MTT assay and the $LC_{50}$ values of $R_1$ and $R_2$ compounds were found to be 38.3 and $43.8{\mu}g/mL$ respectively in the BLT assay. The biochemical and histopathological results revealed that there was no significant hepatotoxicity and nephrotoxicity associated with the ruthenium administration to mice.

Effects of endosulfan (EN), an insecticide, and bleomycin (BL), an antibiotic, on the body weight in the normal mice, and the in vivo cell growth, tumor weight, and hematological parameters of the Ehrlich ascites carcinoma (EAC) cell-bearing Swiss albino mice Mus musculus were evaluated. EN and BL were respectively administered orally and intraperitoneally to the experimental mice; the control group consisted of EAC cell-bearing untreated mice only. EN reduced the body weight in normal mice, whereas BL resulted in a steady body weight compared to the control. EN increased the EAC cell count significantly by reducing the growth of normal viable cells. In contrast, BL reduced the cell count by increasing the proportion of viable cells in the body. The tumor weights induced by EN were significantly higher than those of the EAC control and the BL-treated animals. In comparisons with the control and the BL mice, hematological parameters such as hemoglobin (%) and the number of RBC and lymphocytes were lowered, while counts of WBC, neutrophils, and monocytes were elevated after EN treatments. These results show that BL is capable of reducing the EN-induced neoplastic and haematological alterations in the mice under laboratory conditions.

The plant Bryonia laciniosa (Family: Cucurbitaceae) has been indicated for the treatment of various diseases one among which is cancer. The purpose of this study was investigating experimentally the possible anti-tumor effect and antioxidant role of Bryonia laciniosa leaves in animal model. The methanol extract of Bryonia laciniosa (MEBL) administered at the doses of 62.5, 125 and 250 mg/kg in mice for 14 days after 24 h of tumor inoculation. The effect of MEBL on the growth of transplantable murine tumor, life span of EAC bearing mice, hematological profile and liver biochemical parameters (lipid peroxidation, antioxidant enzymes) were estimated. Treatment with MEBL decreased the tumor volume and viable cell count thereby increasing the life span of EAC bearing mice and brought back the hematological parameter more or less normal level. The effect of MEBL also decreases the levels of lipid peroxidation and increased the levels of glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT). The present work indicates that the methanol extract of Bryonia laciniosa exhibited significant antitumor and antioxidant activity in vivo.
