Polysaccharide fraction isolated from Coriolus versicolor (Copolang) was studied on the antitumor activity and immunostimulation activities with reference to PS-K. Copolang showed nearly equal antitumor activities to the PS-K and exhibited marked augmentation effects on the antibody mediated hypersensitivity reaction, delayed type hypersensitivity reaction and NK-cell activity in tumor bearing mice. But it did not show any noticeable effect on the antibody secreting cell and macrophage function in normal mice. These results indicate that the antitumor activity and immunostimulating effect of Copolang are comparable to those of PS-K.

Polysaccharide fractions were prepared from Forsythia Corea by several different extraction schedules. The fractions obtained were designated as ForCo A, ForCo B and ForCo C respectively. ForCo C was further purified through Sephadex G 200 column chromatography and obtianed two subfractions (Coreana A, Coreana B). ForCo showed marked antitumor activity against sarooma 180 and its activity was dose-dependent. Coreana A, purified from ForCo C, showed somewhat higher antitumor activity. ForCo C increased the number of circulating leucocytes and peritoneal exudate cells, but didn't show any significant effects on the phagocytic activity and total serum protein level. Chemical analysis showed that ForCo C was composed of glucose, galactose, xylose and arabinose. A close relationship between antitumor activities and polysaccharide contents waw observed. These results indicate strongly that antitumor active principle of Forsythia Corea is polysaccharide.

The pine needles, Pinus densiflow Sieb. et Zucc., which is a feed for goats showing a low incidence rate of cancer were evaluated to confirm the potent anticancer effects, with or without several conventional anticancer drugs. The pine needles collected from Mt. Buk-Han located near Seoul were extracted with 95% methanol and methand and concentrated. From the methanol extract, SOM-A, was extracted dichlormethane and SOM-B was extracted with ethyl acetate. SOM-C was extracted with distilled water. These extracts were tested for their antitumor activities in vitro and in vivo. Among them, SOM-A and SOM-C exhibited potent antitumor activities described as belows. 1. The cytotoxic effects of SOM-A and SOM-C were examined against in vitro cultured murine and humman tumor cells. SOM-A showed strong cytotoxicity against human tumor cell lines and SOM-C showed strong cytotoxicity against murine tumor cell lines tested. 2. The antitumor effects of SOM-A and SOM-C were examined against P388 and L1210 of mouse ascitic tumors. The highest mean survival time(MST) ration was 151%(P388) for SOM-C(90mg/kg). 3. To compare the antitumor effects of SOM-A, SOM-B, and SOM-C against solid tumors, S-180 and Ehrlich carcinoma were implanted subcutaneously to mice on Day O. The drugs were given intraperitoneally to mice once a day on Days 1-20, and the tumor weights were measured on Day 21. SOM-A showed inhibition of tumor growth more than 50% in the experiment on S-180 and Ehrlich, and SOM-C also markedly inhibited tumor growth. However, SOM-B had no effect. 4. SOM-C combined with ${\alpha}$-interferon and SOM-C combined with Mitomycin-C enhanced the antitumor activities against murine ascitic tumors P388 leukemia.

This study was carried out for investigating antitumor effects of 5-fluorouracil(5-FU), methotrexate(MTX) and retinoic acid(RA) on hepatocellular carcinoma induced in Sprague-Dawley rat. Antitumor effects were examined a flow cytometric DNA distributions by flow cytometry and stuied ATP/Pi using nuclear magnetic resorance, and the enzymatic activity of thymidylate synthetase and dihydrofolate reductase as well as contents of total collagen and sialic acid were measured with spectrophotometer. In this study, S phase fraction, contents of sialic acid and total collagen were decreased in the induced hepatocellular carcinoma treated with 5-FU and MTX, and synergistic effects of anticancer drugs were exhibited in the hepatocellular carcinoma treated with 5-FU and MTX simultaneously, and the inhibition of thymidylate synthetic and dihydrofolate reductase activity were shown in the hepatocellular carcinoma treated with 5-FU, MTX, and 5-FU and MTX simultaneously. On the other hand, the ratio of ATP/Pi were increased in all groups except group treated with RA. The experimental results suggest that above method may be valuable for evaluating antitumor effect of anticancer drugs.

Objectives : The purpose of this study is to explore the antitumor mechanism and effects of tetrodotoxin through a literature review of experimental and clinical studies. Methods : Medical databases, including The Cochrane Library, Pubmed, NDSL, RISS4u and National Assembly Library, were searched for relevant articles published from January 1, 2000 to October 31, 2014 using the keywords 'tetrodotoxin', 'cancer' and 'tumor'. The results were classified into experimental studies(in vitro and in vivo) and clinical studies. Analysis of the results was conducted on several research areas including the mechanism, antitumor effect and adverse effects of tetrodotoxin(TTX). Results : A total of 34 experimental studies(32 in vitro and 2 in vivo) and 3 clinical studies were found in the search. Most of the experimental studies suggested blocking of voltage-gated sodium channels in metastasis of tumor cells as the main antitumor mechanism of TTX. The most common type of cancers mentioned in the experimental studies were prostate and breast cancer. All of the clinical studies were on the application of TTX on moderate to severe cancer-related pain. No adverse effects of TTX were reported in in vivo studies but mild to moderate adverse events were reported in clinical studies. Conclusions : The results show that tetrodotoxin, which is the main component of Tetraodontidae(commonly known as pufferfish) poison, could be clinically used for antitumor therapy. However, further studies should be conducted on its safety.

Fungal perylenequinones have photodynamic activity and are promising photosensitizers for photodynamic therapy (PDT). Here, we investigated the bactericidal and antitumor activities of phleichrome from the fungal perylenequinone family in vitro. Photodynamic bactericidal activity of phleichrome was analyzed by agar-well diffusion method under dark and illuminated conditions. The photodynamic antitumor activity of phleichrome was analyzed in MCF-7, HeLa, SW480, and HepG2 human cancer cell lines using in vitro cytotoxicity assays. Photodynamic bactericidal activities against Gram-negative and Gram-positive bacteria were species-specific. Antitumor activity against all tumor cell lines increased under the illuminated condition. Depending on the results of the analyses, Phleichrome has potential for further drug development related to its antibacterial and antitumor activities.
