Augmentation of antitumor activity of antitumor drugs in combination with Lactobacillus casei HY2782 (LC2782) was studied against Sarcoma-180 (S-180) and Lewis lung carcinoma (3LL). Antitumor drugs used in this study were 5-fluorouracil (5-fu) and cyclophosphamide (CP). The prolongation effect of LC2872 on the life span of mouse intraperitoneally implanted with S-180 was stronger than that of OK-432 and BCG, while the inhibitory effect of OK-432 and BCG on the growth of 3LL solid tumor was a little stronger than that of LC2782. Average survival rates of mice administrated LC2782, OK-432 and BCG were 192%, 141%, and 112%, respectively, when that of the control was 100%, Intralesional administration of 5-Fu, CP, 5-Fu+LC2782 and CP+LC2782 resulted in 93%, 69%, 99% and 73% inhibition rates against 3LL solid tumor proliferation. The combination therapy of 5-Fu or CP with LC2782 significantly prolonged the life span of S-180-inoculated ICR mice. Average survival rates of mice administrated 5-Fu and CP alone were 115% and 99%. Furthermore, survival rates of mice administrated 5-Fu and CP in combination with LC2782 were 226% and 244%, respectively.

The effects of cylindan, a polysaccharide isolated from the basidiocarps of Agrocybe cylindracea, on murine sarcoma 180 tumor and murine immune cells were examined after intraperitoneal administration. Cylindan exhibited a marked life extension effect in mice against ascite forms of sarcoma 180 and Lewis lung carcinoma at a dose of 50 mg/kg/day, although it did not show any direct cytotoxicity against sarcoma 180, X5563, and MM46 murine tumor cells. Cylindan increased numbers of bone marrow stem cells as well as peritoneal exudate cells in flow cytometry using monoclonal antibodies. The tumor bearing mice group apparently showed the increase of macrophages and cytotoxic T lymphocytes in mouse spleen cells during the early stage of tumor growth. But during the later stage, the control group decreased immune cells and cylindan restored the decreased immune cells in the tumor bearing mice to the normal level. In non-specific immune response, cylindan stimulated the bacterial phagocytosis and acid phosphatase production in macrophages. It also activated components of the alternative complement pathway and natural killer activity against YAC-1 lymphoma. In number of plasma cells as token of stimulation of the differentiation of B lymphocytes. In cellular immunity, cylindan restored the depressed response of delayed type hypersensitivity in the tumor bearing mice to 60% of the normal level and increased the interleukin-2 (IL-2) responsiveness in the IL-2 dependent CTLL-2 cells. These results suggest that cylindan did not show direct cytotoxic effects on tumor cells but restored the decreased immune response of the tumor bearing mice.

Objectives : The aim of this study was to experiment the antitumor activity of Agrimonia pilosa Ledebour (APL) in human stomach cancer (AGS) cell lines (in vitro) and male C57BL/6J mouse (in vivo). Methods : The effects of the ethanol extract from the plant on several transplantable rodent tumors were investigated in vitro by 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxy phenyl)-2-(4-sulfophenyl)-2H-tetrazolium, inner salt (MTS) assay. DNA content analysis and Western blot analysis. Agrimonia pilosa Ledebour (APL) was given to rats with Lewis Lung Carcinoma (LLC) cells. The experimental rats were divided into 3 groups in vivo. Saline was injected into the abdominal cavity in the first group, 50 mg/kg APL was injected into the abdominal cavity in the second group and 100 mg/kg was injected into the abdominal cavity in the third group. After that, we checked their tumor volume periodically. Results : At first, human gastric cancer (AGS) cell lines (in vitro) showed decreased cell viability, and increased $sub-G_1$ contents. When we experimented rat intestinal epithelial (RIE)l as same condition, this result didn't show. With this, compared to normal cells, Agrimonia pilosa Ledebour (APL) led selectively to the extinction of cells only in human gastric cancer. Moreover, we showed that the traditional herbal medicine APL induced caspase-dependent apoptosis in AGS cells. Next, APL inhibited the growth of LLC-bearing mouse tumor. However, we could not verify APL induced caspase-dependent apoptosis in LLC-bearing mouse tumor. Conclusions : The roots of Agrimonia pilosa Ledebour (APL) contain some antitumor constituents.

The purpose of this study is to prepare black ginseng and evaluate its antitumor activity. In order to achieve such aim, 5 year fresh ginsenges were steamed at 95'E for 3 hr in pottery apparatus and dried at $60^{\circ}C$ for 12-36 hr. This process was repeated again nine times in same condition. Among the ginseng saponins in black ginseng, the amount of Ginsenoside $Rg_3$ was examined by HPLC. 10.05 mE of Ginsenoside $Rg_3$ was obtained from 1 g of dried black ginseng prepared. The extract of black ginseng exhibited stronger cytotoxic activity against MCF-1, HT-1080 and Hepa 1C1C7 tumor cell lines in vitro than the extract of red ginseng. Also, the extract of black ginseng exhibited stronger antitumor activity(33%) in BDFl mice bearing Lewis lung carcinoma cells(LLC) than the extract of red ginseng(23%). From these results, it was concluded that Black ginseng had antitumor activity suggesting its application for the prevention and treatment of cancer.
