The microstructure, tensile and impact properties of forgings of 7175 aluminium alloy have been studied as a function of intermediate thermo-mechanical treatment(ITMT) process. The ITMT process is consisted of warm working and recrystallization. In the case that the billet was warm-worked above 60% below 250℃ and recrystallized at 475℃, the grain size revealed about 17㎛ which corresponds to one third of that of conventional process. The refinement of grain size leaded to the improved ductility and impact energy without sacrifice of tensile strength. It was found that the ITMT processed specimen behaved isotropically due to the near equiaxed grains. It was observed that the ITMT processed specimen showed the mixed fracture mode of transgranular and intergranular, instead of intergranular mode. This change of fracture mode contributed to the improved ductility and impact property.

Climical studies were carried out 83 cases of patients with colorectal cancer treated bv Hangamdan(抗癌丹) from January lth 1998 to September 30th 2000. The results were summarized as follows; 1. Distribution of those attached by colorectal cancer, by sex, showed that Male is more then Female, by age, showed that the numbber of fifties is majorith. 2. distribution of diagnostic stage, in descending order; stage Ⅲ(53%, top), stagew Ⅵ(45.8%). 3. The effects of maintenance and improvement in the symptoms with traditional oriental therapy(83.3%) and combined treatment of westem and oriental therapy(92.1%)were boserved. The effects of the symptoms were as folows: diarrhea(37.3%),abdominal pain (25.3%), general body weakness(22.9%), nausea(20.5%) and etc. in orders. 4. Analysis of hematology attached by colorectal cancer, maintenance and increasing of WBC(89.9%), RBC(74.7%), Hgb(81.1%), Platelet(92.4%) were Observed. After taken Hangamdan, the satety of the liver and kidney were as follows; maintenance and decreasting of AST(85.9%), ALT(94.8%) , GTP(87.5%), Creatinine(90.9%) were observed. 5. of IL-12 and IFN-λ attached by colorectal cancer, increasing of IL-12(53.3%), IFN-λ(80%) were observedl. 6. Analysis of QOL attached by colorectal cancer, maintenance and improvement of combined treatment of western and oniental therapy(89.6%), traditional oriental therapy(83.3%) were observed. 7. Analysis of survival in patients with Ⅳ stage of colorectal cancer, above 7 months(18.4%), 12 months(65.8%). 8. Analysis of antitumor effects, maintenance of traditional oriental therapy(83.3%) and maintenance and improvement of combined treatment of western and oriental therapy(80.5%) were observed. Analysis of tumor marker attached by colorectal cancer, maintenance and decreasing of CEA(78.8%) were boserved 9. Analysis of curative valuation, maintenance and improvement of traditional oriental therapy(83.3%), combined treatment of westem and oriental therapy(72.7%) were observed.

Objective: The purpose of this study is to develop and activate anti-tumor herbal acupuncture for cancer patients in South Korea. Methods: We investigated some literatures on anti-tumor herbal acupuncture which is used in South Korea and China, and made diagrams. Results: The results are summarized as follows. Anti-tumor herbal acupuncture is one of the traditional oriental medical method which is effective for cancer patients. In domestic studies, most of herb materials are belong to action of cooling&detoxification(25.0%) and strengthening body resistance(46.4%) which are proved to have effects of anti-tumor, immune activation and preventing tumor. In China, point injection therapy are used for improving symptoms of cancer patients and hea1ing tumor. Also herbal intravenous injection is used for combination of chinese traditional and western cancer therapy and treating cancer patients variously. Conclusions: From the above results. it is expected that anti-tumor herbal acupuncture is useful to improve clinical symptoms and quality of life(QOL) of cancer patients. Also we must develop new progressive methods of point injection and herbal intravenous injection for treating cancer patients, and advance clinical studies and trials.

Clinical studies were carried out 83 cases of patients with colorectal cancer treated by Hangamdan(抗癌丹) from January 1th 1998 to September 30th 2000. The results were summarized as follows; 1. Distribution of those attached by colorectal cancer, by sex, showed that Male is more then Female, by age, showed that the number of fifties is majority. 2. Distribution of diagnostic stage, in descending order; stage III(53%, top), stage IV(45.8%). 3. The effects of maintenance and improvement in the symptoms with traditional oriental therapy(83.3%) and combined treatment of western and oriental therapy(92.1%) were observed. The effects of the symptoms were as follows: diarrhea(37.3%), abdominal pain (25.3%), general body weakness(22.9%), nausea(20.5%) and etc. in orders. 4. Analysis of hematology attached by colorectal cancer, maintenance and increasing of WBC(89.9%), RBC(74.7%), Hgb(81.1%), Platelet(92.4%) were observed. After taken Hangamdan, the safety of the liver and kidney were as follows; maintenance and decreasing of AST(85.9%), ALT(94.8%), GTP(87.5%), Creatinine(90.9%) were observed. 5. of IL-12 and $IFN-\gammer$ attached by colorectal cancer, increasing of IL-12(53.3%), IFN-{\gammer}(80%)$) were observed. 6. Analysis of QOL attached by colorectal cancer, maintenance and improvement of combined treatment of western and oriental therapy(89.6%), traditional oriental therapy(83.3%) were observed. 7. Analysis of survival in patients with IV stage of colorectal cancer, above 7 months(18.4%), 12 months(65.8%). 8. Analysis of antitumor effects, maintenance of traditional oriental therapy(83.3%) and maintenance and improvement of combined treatment of western and oriental therapy(80.5%) were observed. Analysis of tumor marker attached by colorectal cancer, maintenance and decreasing of CEA(78.8%) were observed. 9. Analysis of curative valuation, maintenance and improvement of traditional oriental therapy(83.3%), combined treatment of western and oriental therapy(72.7%) were observed. From the above results, it is suggested that Hangamdan has significant effects of antitumor and immune activity, also could be usefully applied for colorectal cancer patients by combination with western therapy or alone.
