In order to estimate the effects of Eucommiae Cortex, which is one of the most important herb medicines used for invigorating the liver and kidney and strengthening ones and muscles, fetus-soothing etc., this experiment was conducted the quantitative analysis of geniposidic acid and geniposide by HPLC, and the analgesic effects of mice, the lipid metabolism of rats, the catecholamine concentration in the brain and the plsma of rats stressed by immobilization. The results obtained are as follows. 1. The contents of geniposidic acid and geniposide were 22.3mg/g, 5.4mg/g in Eucommiae Cortex without processing, and 119.8mg, 10.4mg/g in Eucommiae Cortex fried with salts. 2. In analgesic effects of mice, there were all significant in Eucommiae Cortex without processing and Eucommiae Cortex fried with salts. 3. In the effects of lipid metabolism of rats, there were not significant on the change of organ weight and the level of serum total lipid and total cholesterol, triglyceride, phospholipid, HDL-cholesterol. But, there were significant on the level of free fatty acid. 4. In tile effects of the catecholamine concentration in the brain and the plsma of rats stressed by immobilization, there were all significant in Eucommiae Cortex without processing and Eucommiae Cortex fried with salts, especially in case of norepinephrine. From the results mentioned above, there were significant on the analgesic effects of mice, and the catecholamine concentration in the brain and the plsma of rats stressed by immobilization. And there were different from Eucommiae Cortex without processing and Eucommiae Cortex fried with salts in the contents of geniposidic acid and geniposide. These results are relative to invigorating the liver and kidney and strengthening ones and muscles, and fetus-soothing, therefore when we use Eucommiae Cortex, it is more desirable to use Eucommiae Cortex with processing.

The purpose of this study is to investigate the effects of Ginseng saponin on the cadmium which is widely distributed in the environment, results in immune system alteration. For the experiments, 125 mice of ICR strain were used. The experimental groups were divided into 5 groups a control, a cadmium alone treatment group, three Cd and saponin (10, 50, 100 mg/kg) combined treatment groups. The mice were allocated 25 to each group and observed for 8 weeks. The results of experiment are as follows: 1. Body weight growth rates during 8 weeks were as this control group 36.47%, Cd alone group 32.48%, saponin combined treatment group (10, 50, 100 mg/kg) 32.49%, 39.17%, 24.27% respectively. 2. In all groups, the relative weights of liver and kidney were increased, compared with control group. In the case of spleen, saponin combined treatment group (50, 100 mg/kg) was high to the significant level compared with a control group (p<0.05). Thymus was not. 3. On blood lymphocyte count observation, Cd alone treament group has 25.6% less than control group, and saponin combined treatment group have increasing trends. but in thymus and spleen, there was no trends like blood. 4. On antibody titer, there was no difference among groups. 5. On total serum protein, saponin (100 mg/kg) combined treatment group was high to significant level compared with control group (p<0.05), and other treatment groups have increasing trends. 6. Cd accumulation in kidney was higher than in liver, and all treatment groups were high to the very significant level compared with the control group (p<0.05), but there was no difference among groups. From the results of this study, it can be concluded that the oral administration of Cd results in alteration of immune system and Ginseng saponin prevents this effect. But, Cd accumulation was not affected by saponin.

Effects of garlic powder supplementation on blood lipid profile and antioxidant system were investigated in rats with and without swimming exercise. Sprague-Dawley rats of four experimental groups were fed for 4 weeks diets containing $15\%$ beef tallow and $1\%$ cholesterol; control without garlic and exercise, Go with $2\%$ garlic alone, Ex with exercise alone, GoEx with $2\%$ garlic and exercise. Rats were trained 40 min a days a days a week. Group Ex and GoEx showed significant lowering in body weight gain and fat accumulation. In Go, Ex and GoEx, plasm TG and LDL-C were lower and HDL-C was higher, although not significantly, compared to levels in control. Total cholesterol was significantly reduced in group Go, and Ex and GoEx were lower than control. The total/HDL cholesterol ratio was also found to be significantly different, decreasing the ratios in Go, Ex and GoEx. The hepatic TBARS increased significantly in group Ex $(51.7{\pm}3.43nM/g\;liver)$, while TBARS in Go and GoEx were low $(35.68{\pm}3.61,\;39.30{\pm}5.55nM/g\;liver)$ and similar to control's one. The activity of hepatic SOD in Go and GoEx tended higher than control and Ex without garlic. The hepatic catalase showed significantly the highest activity in Go. Activity of GSH-px was significantly low in Ex with $0.14{\pm}0.03$ unit/mg protein, and control, Go and GoEx had higher activities of $0.23{\pm}0.08,\;0.20{\pm}0.07,\;0.22{\pm}0.01\;unit/mg$ protein, respectively. Lower activities of antioxidant enzymes in Ex are likely to associated with the highest level of TBARS. It seems that a decrease in TBARS in GoEx relative to Ex was related to the increase in GSHpx and SOD with garlic supplemented, which led to compensate the oxidative stress from exercise. The results suggests that exercise or garlic supplement exerts blood lipid attenuating effect. In adition, garlic supplementation could strengthen the antioxidant potential against exercise-induced oxidants, partly by modulating oxidant enzyme activity. These effects of garlic may make it a beneficial agent on CVD.

Forty-eight individually fed Angus steers (body weight $220kg{\pm}9.1$) were utilized to investigate the effects of copper (Cu) source and concentration on lipid metabolism and carcass quality. Steers were stratified by body weight and initial liver Cu concentration and randomly assigned to one of five groups. Groups were then randomly assigned to treatments. Treatments consisted of: 1) control (no supplemental Cu); 2) 10 mg Cu/kg DM from $CuSO_4$; 3) 10 mg Cu/kg DM from a Cu amino acid complex (Availa Cu) 4) 20 mg Cu/kg DM from $CuSO_4$; and 5) 20 mg Cu/kg DM from Availa Cu. Steers were fed a corn-alfalfa-based growing diet for 56 d. Steers were then switched to a high concentrate finishing diet for 145 d. On day 74 of the finishing phase subcutaneous adipose tissue biopsies were obtained from three steers/treatment to determine basal and stimulated lipolytic rates in vitro. Steers were then slaughtered after receiving the finishing diet for 145 d. Control steers tended (p<0.12) to have lower ceruloplasmin (Cp) activity than Cu supplemented steers. Steers receiving 20 mg Cu/kg DM from Availa Cu had higher (p<0.03) Cp activity than steers receiving 20 mg Cu/kg DM from $CuSO_4$. Plasma non-esterified fatty acids were similar across treatments. Steers receiving 10 mg Cu/kg DM from Availa Cu had higher (p<0.02) total plasma cholesterol concentrations relative to steers receiving 10 mg Cu/kg DM from $CuSO_4$. Steers receiving 20 mg Cu/kg DM from Availa Cu had lower (p<0.03) plasma triglyceride concentrations than steers supplemented with 20 mg Cu/kg DM from $CuSO_4$. Fatty acid profile of longissimus muscle was similar across treatments. Backfat depth tended (p<0.18) to be lower in Cu supplemented steers relative to controls. Steers supplemented with 20 mg Cu/kg DM from Availa Cu had heavier (p<0.03) hot carcass weights and a greater (p<0.02) dressing percentage than steers supplemented with 20 mg Cu/kg DM from $CuSO_4$. Furthermore, in vitro basal (p<0.06) and epinephrine stimulated (p<0.04) lipolytic rates of subcutaneous adipose tissue were higher in Cu supplemented steers relative to controls. The results of this study suggest that Cu supplementation has minimal effects on blood and lean tissue lipid profile. However, it appears that Cu may play a role in lipid metabolism in subcutaneous adipose tissue.

This study was conducted to investigate the effect of dietary domestic Skullcap (Scutellaria baicalensis) extracts (SCE) on laying performance and egg quality in laying hens. There were no significant differences in feed intake, egg production, or relative liver and spleen weights. The egg weights in groups fed diets containing SCE were significantly increased as compared with the control. The number of cecal total microbes in the group fed a diet containing 0.5% SCE was significantly reduced as compared with other groups. The malondialdehyde contents in stored eggs were significantly lowered by feeding SCE. The Haugh unit in the groups fed diets containing SCE tended to be increased after 2 weeks storage, but not significantly. This result indicated that dietary domestic SCE may delay lipid oxidation in eggs when added to laying hen diets.

The benefits of milk on the rats supplemented with cholesterol and vitamin D2 in diet was investigated. A total of 150 male rats of Sprague-Dawley strain, 5 weeks of age, were divided into 6 groups with the diet. Cholesterol control group was fed the diet containing 1.0% choleterol and 50,000 IU/100 g of vitamin D2 for 24 months, and M0.5, M1, M2 and M5 of milk groups were fed the diet containing cholesterol, vitamin D2 and 0.5, 1, 2 and 5 of reference daily intakes of whole milk, respectively. No remarkable differences of growth, diet intake, and food effciency ratio among groups were observed though rats in cholesterol control group showed abrupt decrease of diet intake and body weight showed slightly higher relative organ weights than did the rats in control group. The rats in cholesterol control group showed the highest serum total cholesterol level. The rats in milk groups showed lower total cholesterol level and higher high density lipoprotein (HDL)-cholesterol fraction than did the rats in cholesterol control group though no tendency was observed among milk groups. In milk groups, aorta, heart, kidney and liver of rats showed milder calcification and necrosis or fat degeneration compared with those in cholesterol control group. The above results suggest that whole milk could have beneficial effect on the cholesterol-and -vitamin D2-induced atherosclerosis in rats.

The preventive effects of ginseng and aloe extract on cigarette smoke-induced hepatotoxicity to Spague-Dawley rats were investigated. The experimental rats were exposed smoke by inhalation for 5 weeks, 3 times per day, and 15 minutes each time. Also ginseng and aloe extract (Group G+A), aloe (Group A) or ginseng (Group G) were administered to each group, but the positive control rats (Group C) were exposed smoke without any other special treatments. Group C showed decreased food intake and increased water consumption. Also the reduction of body weight and the increase in serumAST, ALT, triglyceride and alkaline phosphatase were observed. The relative liver weights of group C were increased and the hepatic parenchyma revealed light brownish red grossly. On histopathologic observation, the hepatocytes of group C animals exhibited diffuse swelling which narrowed the, sinusoidal lumen and disarrayed the hepatic cord-like arrangement. Diffuse necrosis of the hepatocytes was also observed. However, degeneration and necrosis of the hepatocytes were milder in group G+A. In the case of group A, the damage was moderate, while the group G showed marginal improvement from group C. Electronmicroscopically, peroxisome increased and mitochodria decreased in group C. Various hepatic damages related to smoking in group C revealed recovering tendency in group G+A. This study indicated that daily administration of ginseng and aloe could decrease and even prevent cigarette smokeinduced hepatotoxicity.

The present study was undertaken to investigate the effect of biphenyl dimethyl idcarboxylate (PMC) on the humoral immunosuppression by ketoconazole (KCZ) in ICR mice. PMC at a dose of 6 mg/kg was administered orally to mice daily for 14 consecutive days. KCZ was suspended in RPMI 1640 medium and orally administered at 160 mg/kg/day 2 hrs after the administration of PMC. Mice were immunized an challenged with challenged red blood cells (SRBC). The results of the present study are summarized as follows; a gain of body weight and relative weights of spleen and liver were significantly increased by combination of PMC and KCZ, as compared with those in mice treated with KCZ alone. Splenic plaque forming cells (PFC) and hemagglutination (HA) titers to SRBC were greatly enhanced by the combination of PMC and KCZ, compared with treatment of KCZ alone. The elevation of serum glutamicpyruvic transminase (S-GPT) and total protein levels caused by KCZ were reduced to normal level by the combination of PMC and KCZ. In addition, lower serum albumin and A/G ratio were also increased to normal level. These findings indicate that PMC has a protective effect against KCZ-induced humoral immunosuppression.

Our former study indicated efficacy of apoptotic cell death on animal study by using Egg white combined Chalcanthite (EC). Clinically, bamboo salt is using because of safety. Hence we investigated a toxicity study for determining safety by adding bamboo salt in former materiel. We had two studies: toxicity of EC and of Bamboo salt with egg white combined Chalcanthite (BC). Both were studied in 1-week single and 5-week repeated oral dose toxicity tests on male Imprinting Control Region mice. In EC, doses used in 1 week single oral dose toxicity tests were 0, 0.05, 0.5, 5 and 50 mg/kg/day and 0, 0.01, 0.05, 0.25 and 0.5 mg/kg/day. In BC, doses used by 0, 0.08, 8.3, 83.3 and 166.6 mg/kg/day in single oral dose toxicity and 0, 4.2, 8.3, 41.7 and 83.3 mg/kg/day in repeated oral dose toxicity tests. Their blood and urine were assayed and organ morphology were examined. Mann-Whitney U test and ANOVA tests were used by analysing methods. First, significant increased left renal weight in all groups of EC and BC. Second, increased ALT score was found in EC-S2 and increased relative liver weight was found in EC-S3. In addition, increased relative weight and urine bilirubin and urobilinogen were found in EC-R2 and EC-R3. There was no significant toxic change in BC. The Mixture of EC had a possibility of hepatotoxicity in the short and long term. Processed BC appears to be safe and non-toxic in these studies and a no-observed adverse effect level (NOAEL) was established at 83.3 mg/kg/day in mice. Relatively, The BC were safer than The EC.
