1. Objects of Research This research is purposed to find Dong-mu's thought on Pharmacology, through summarizing sentences related to pharmacology proposed in the chief writings on Sasang Constitutional Medicine. 2. Methods of Research It was researched bibliologically with Dong-mu's chief medical writings such as "Dongyi Suse Bowon Sasang Chobongyun(東醫壽世保元四象草本卷)", "Dong-mu's posthumos work(東武遺藁)", "Dongyi Suse Bowon(東醫壽世保元)". 3. Results and Conclusions 1. The grouping criteria according to the constitution proposed in "Dongyi Suse Bowon Sasang Chobongyun" is 'Spreading Outside' 'Hardening Inside' 'Cooling Organ' 'Warming Inside', but the grouping of medical herbs according to the constitution is yet not accomplished, and medical herbs is comprehended on base of effectiveness as like existing oriental medicine. 2. The grouping criteria according to the constitution proposed in "Dong-mu's posthumos work"is 'Spreading Choking Raising Lowering' and 'Perfume Smell Fluid Taste', and medical herbs is comprehended on base of effectiveness as like "Chobongyun", and the example on mixing of the herb classified according to the constitution is showed. 3. The medical herbs are comprehended on the basis of how to effect on treatment of constitutional disease, and the principle that it's not to mix of the herb classified according to the constitution is proposed in "Dongyi Suse Bowon". 4. The pharmacology of Sasang Constitutional Medicine is accomplished after it is modified many ti mes through clinic experience for a long time. 5. The pharmacology of Sasang Constitutional Medicine in the early period, is to comprehend herbs on the basis of how to complement 'Spreading Gathering Raising Lowering' of 'Small-Organ(偏小之臟)' according 'Qi-Mei(氣味)' and effectiveness, but that in the late period is to comprehend herbs on the basis of how to complement or to control 'Small-Organ(偏小之臟)' and 'Large Organ(偏大之臟)'.

Acanthopanax koreanum Nakai, a well known traditional herb grown in Jeju Island, South of Korea, has been used as a tonic and sedative agent, as well as in the treatment of diabetes and immune diseases. Mutagenicity of two lignans, syringaresinol and tortoside A isolated from A. koreanum, was assessed using Salmonella/microsome (Ames) test. Tester strains used were Salmonella typhimurium TA98, TA100, TA1535, and Escherichia coli WP2uvrA. The mutagenic activity was determined both in the absence or presence of S9 mixture. As a result, tortoside A did not cause any increase in the number of $his^+$ revertants in S. typhimurium and E. coli WP2uvrA strains in the presence or absence of S9 mix, compared to the controls. Similarly, low concentrations of syringaresinol (750 and 1,500 ${\mu}g$/plate) did not show any mutagenic properties in all bacterial strains, in the presence or absence of S9 mixture. However, in the high concentration of syringaresinol (3,000 ${\mu}g$/plate), the number of revertants were increased in TA1535 strains, in the absence of S9 metabolic activation. Therefore, in vivo experiments such as comet assay are needed to further determine the genotoxic/carciogenic potential of syringaresinol isolated from A. koreanum.

This study aimed to address problems and suggest solutions in applying seed mixture design criterior of slope revegetation works according to the "Slope revegetation design and guidelines(proposed)" proposed by the Ministry of Construction and Transportation. To do this, a proper thickness of attaching soil media was identified in April experiment where the thickness and slopes varied. The results were as follows. In the test, the coverage rate of plot where exotic grass was not sowed increased with time and was 79.3% after three months of seeding, which indicated less risk of soil erosion. When applying the provisional standards of the plant mix proposed by the Ministry of Construction and Transportation, tree seeds and native plants were found ill in the early stage in all test lands due to exotic grass. This was because exotic grass which grew well in the early stage, could grow densely, so it might hamper the growth of other plants. When slope revegetation were planted and goals were set for herb, shrub and tree dominant mixture types, it was required to shift focus toward nursing up native plants first rather than early plantation of exotic grass.

In this study, we carried out the preparing standardization and regulation of processed Glycyrrhizae Radix (PGR) which have been widely used in oriental medicines. Glycyrrhizae Radix(GR) have been generally prepared by the stir-frying, or mix-frying with honey for the purpose of decreasing sweetness and augmenting vitality. Firstly, we tried to standardize PGR prepared by the stir-frying. We purchased 14 kinds of PGR and non-processed GR(NPGR) at oriental physician's offices and oriental pharmacies on a nation scale, respectively. The amounts of dry on loss, water extract, diluted ethanol extract, ether extract, total ash, acid insoluble ash, glycyrrhizin(GL), glycyrrhetic acid(GA) and liquiritin(LQ) of them were examined. The amounts of dry on loss, GL and LQ in commercial PGRs showed remarkable decrease, while GA showed increased as compared with NPGR. In order to standardize preparing method of PGR, the effect of heating time on physico-chemical parameters and biological activities were examined. Physico-chemical parameters such as dry on loss, extract amount, GL and LQ contents in PGRs showed decrease, however, GA was increased with heating time as compared with NPGR. Also, GA, obtained from heat-treated GR, was found as an artifact in PGRs. PGR was more effective than NPGA in vitro test of DPPH scavenging effect and TBA-Rs reducing effect. PGR and NPGR showed potent hepatoprotective effect on $CCl_4-intoxicated$ rats. Especially, PGR prepared by 80 min of heating was the most effective. Considering these results, the optimal condition for PGR preparation was $150^{\circ}C$ for 80 min.

The objective of this experiment was to investigate the effect of dietary supplementation of copper-soy proteinate (Cu-SP) and herbal mixture (HBM) on growth performance, intestinal microflora, and immune response in broiler. A total 1,000 1-d old ROSS 308 (initial $BW=41{\pm}0.38g$) were randomly allotted to 1 of 5 dietary treatments with 4 replicates during d 35 of the feeding trial. Dietary included: (1) Control : control diet, (2) Antibiotics : control diet + Avilamycin 6 ppm, (3) Cu-SP : control diet + 100 ppm Cu-soy proteinate, (4) HBM : control diet + 0.15% herbal mixture, (5) Cu-SP+HBM : control diet + 100 ppm Cu-soy proteinate + 0.2% herbal mixture. Two-phase feeding program with a starter diet from d 0 to 21, and a finisher diet from d 22 to 35 was used in the experiment. Within each phase, a diet was formulated to meet or exceed NRC requirements of broilers for macro- and micronutrients. The diet and water were available ad libitum. Result indicated that during d 22 to 35 and over all periods of the experiment, feed intake and feed conversion ratio were greater (P<0.05) for other treatment than control. Significant differences were found in lymphocyte (LY), and stress indicator (HE:LY ratio). Lymphocyte was greater (P<0.05) for Cu-SP + HBM treatment than control. However, stress indicator (HE:LY ratio) were greater (P<0.05) for control than Cu-SP + HBM treatment. The plasma IgG was higher (P<0.05) in the antibiotics, HBM, and Cu-SP+HBM treatments groups compared with control. The population of Clostridium perfringens in the antibiotics, Cu-SP, HBM, Cu-SP + HBM treatment groups were lower (P<0.05) than those control. These result suggested that dietary copper-soy proteinate or herbal mixture may be used as an alternative to antibiotics to improve growth performance, and intestinal health of birds.

The objective of this experiment was to investigate the effect of dietary supplementation of copper-soy proteinate (Cu-SP) and herbal mixture (HBM) on growth performance, blood parameter, and immune response in laying hens. A total 800 Hy-Line Brown laying hens (60 weeks old) were randomly allotted to 1 of 4 dietary treatments : (1) Control : control diet, (2) Cu-SP : control diet + 100 mg/kg Cu-soy proteinate, (3) HBM : control diet + 0.15% herbal mixture, and (4) Cu-SP + HBM : control diet + 100 mg/kg Cu-soy proteinate + 0.15% herbal mixture. Each treatment was replicated 5 times with forty birds units were arranged according to randomized block design. Feeding trial lasted 5 weeks under 16L : 8D lighting regimen. The diet and water were available ad libitum. Result indicated that during feeding trial of the experiment, hen-day egg production was significantly (P<0.05) higher in Cu-SP and HBM treated groups than control. However, feed intake, feed conversion ratio, egg weight, broken and shell less egg production were not significantly influenced by treatments. Eggshell strength was significantly (P<0.05) higher in Cu-SP than control. Eggshell thickness, eggshell color, egg yolk color, Haugh unit were not significantly influenced by treatments. The level of WBC and stress index (heterophil : lymphocyte) were higher in supplemented groups than the control. The concentration of plasma IgG was higher in supplemented groups than the control. The result of this experiment showed that dietary copper-soy proteinate or herbal mixture tended to improve egg production and affect positively on immune response of laying hens.
