To evaluate the antitumor activity and antimetastatic effects of HDBT, studies were done experimentally. The results were obtained as follows: 1. HDBT extracts didn't show cytotoxicity against BALB/C mouse lung fibroblast cell. 2. In cytotoxicity against A549, SK-OV-3, B16-BL6 and HT1080 concen- tration inhibiting cell growth up to below 30% of control was recognized at $10^{-3}g/ml$ of HDBT. 3. The concentration inhibiting adhesion of A549 and B16-BL6 to complex extracellular matrix up to below 30% of control was recognized at $10^{-3}g/ml$ of HDBT. 4. In Inhibitory effect on activity of DNA topoisomerase I, the $IC_{50}$ was shown $200-300{\mu}g/m{\ell}$ of HDBT. 5. The T/C% was 137.9% in HDBT-treated group in S-180 bearing ICR mice. 6. In CAM assay, HDBT extracts inhibited angiogenesis significantly at $15{\mu}g/egg$ concentration as compared with control. 7. In pumonary colonization assay, a number of colonies in the lungs were decreased but insignificantly in HDBT-treated group as compared with control group. 8. In hematological changes in B16-BL6 injected C57BL/6, numbers of WBC were decreased significantly in HDBT-treated group but numbers PLT were increased insignificantly as compared with control. From above results it was concluded that HDBT could be usefully applied for the prevention and treatment of cancer.

To evaluate the antitumor activity, antimetastatic and radioprotective effects of Kamisasammaekmundongtang(KSMT), studies were done experimentally. The results were obtained as follows: 1. In cytotoxicity against P388, A549 and B16-F10, KSMT was not showed satisfiable cytotoxicity as compared with control. 2. In Inhibitory effect on activity of DNA topoisomerase I, KSMT has strong inhibitory effect. 3. The inhibitory effect on adhesion of A549 to complex extracellular matrix was significantly increased at 0.5mg/ml, 1mg/ml of KSMT. 4. The T/C% was 122 in KSMT treated group in S-180 bearing ICR mice. 5. In antiangiogenetic effect on CAM assay, inhibitory rate was 33% in KSMT treated group. 6. In pulmonary colonization assay, a number of colonies in the lungs were decreased significantly in KSMT treated group as compared with control group. 7. By FACS analysis of splenic leukocyte after exposure to radiation by linear accelerator, T-helper cell, B cell and macrophage in KSMT treated group were significantly increased while splenocytes were decreased in control group. 8. In histological changes of jejunum of $Bald{\setminus}C$ mice after exposure to radiation by linear accelerator, exclusion and fusion of villi were decreased as compared with control group. But in duodenum and ileum, exclusion and fusion of villi were not decreased as compared with control group. 9. WBC, PLT were increased in KSMT treated group as compared with control group after exposure to radiation by linear accelerator, but the increasing effect was not significant. Above results suggest that KSMT may be useful in prevention of cancer metastasis and protection from damage by radiotherapy. But the further study of KSMT would be demanded.

To evaluate the antitumor activity and antimetastatic effects of Hongsam -daibotang(HDT-C), studies were done experimentally. The results were obtained as follows: 1. In cytotoxicity against A549, SK-OV-3 and B16-BL6 concentration inhibi ting cell growth up to below 30% of control was recognized at $10^{-3}g/ml$ of HDT-C. 2. The T/C% was 145.4% in HDT-C treated group in S-180 bearing ICR mice. 3. In Inhibitory effect on activity of DNA topoisomerase I, the $IC_{50}$ was shown $100-200{\mu}g/ml$ of HDT-C. 4. The expressing $TNF-{\alpha}$ was increased in HDT-C treated group as compared with control. 5. The expressing MMP-9 was decreased in HDT-C treated group as compared with control. 6. HDT-C extracts exhibited efficient adhesive effect of A549, B16-BL6 cell to complex extracellular matrix. 7. In CAM assays, angiogenesis was significantly inhibited in HDT-C treated group than control group. 8. In pumonary colonization assay, a number of colonies in the lungs were decreased significantly in HDT-C treated group as compared with control group. 9. In hematological changes in B16-BL6 injected C57BL/6, numbers of WBC and were decreased insignificantly and also those of platelet were increased insignificantly in HDT-C treated group as compared with control. 10. In the histological changes of lung in B16-BL6 injected mice, infiltration of cancer cells were inhibited effectively in HDT-C treated groups whereas many cancer cells were infiltrated into erivascular and peribronchiol of control group. These results suggested that HDT-C extracts might be usefully applied for prevention and treatment of cancer.
