The effects of Curcuma extract Solomon's seal (Polygonatum odoratum var. pluriflorum), and maltodextrose on acute hepatotoxicity in Sprague-Dawley (SD) rats were investigated. Acute hepatotoxicity was induced by 0.5 mL of carbon tetrachloride ($CCl_4$) per kg of SD rats, which was injected to them before administration of Curcuma extract or both Solomon's seal (Polygonatum odoratum var. pluriflorum) and maltodextrose mixtures. SD rats dose with Curcuma extract of 4 mg or 40 mg per kg per day significantly (p<0.05) reduced the levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALKP) after 7 days compared to the controls dose with water. Treatments of Curcuma extract with 4 mg per kg per day in SD rats significantly (p<0.05) reduced aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALKP) to 78.0%, 82.6%, and 76.3% after 7 days compared to the controls, respectively. The levels of AST and ALT in SD rats dose with both Solomon's seal (Polygonatum odoratum var. pluriflorum) and maltodextrose mixtures or either alone had no significantly different (p>0.05) compared to the controls. Treatments of Curcuma extract combined with Solomon's seal (Polygonatum odoratum var. pluriflorum) and maltodextrose mixtures was 'liked more' to the sensory scores for odor and flayer compared to the controls. It was considered that Curcuma extract combined with both Solomon's seal (Polygonatum odoratum var. pluriflorum) and maltodextrose mixtures could be used to functional food for enhancement of health and consumer acceptance.

The aim of the present study was to investigate effects of a 12-week aerobic exercise training program and a gym-ball exercise training program on body composition, aspartate aminotransferase (AST), alanine aminotransferase (ALT), adipokines, and cardiovascular risk factors in obese children with nonalcoholic fatty liver disease. The subjects were separated into two groups, an aerobic exercise group (n=10), which practiced moderate aerobic exercise training for 12 weeks, and a gym-ball exercise group (n=13), which practiced resistance exercise training for 12 weeks. The results of the analyses are as follows: Weight, body mass index, and body fat were significantly lower (p<0.01, respectively), whereas the $VO_2$ max was higher in both groups (p<0.01). Fasting glucose, insulin and HOMA-IR levels were significantly decreased in the gym-ball exercise group (p<0.05), whereas adiponectin, AST, and ALT levels were significantly increased (p<0.05, p<0.001, p<0.001, respectively) in both groups after the 12-week exercise training program. In addition, our results showed that HOMA-IR, insulin, and concentrations of C-reactive protein (CRP) were significantly lower in both groups. They demonstrate that a 12-week program of regular aerobic exercise or gym-ball exercise yields beneficial effects such as an amelioration of cardiovascular risk factors, body indices, and liver function in obese children with nonalcoholic fatty liver disease.

This study has attempted to examine the effect of Artemisia princeps and A. argyi on liver function-related enzymes in rats with $CCl_4$ adminisration. The activities of serum aspartate aminotransferase(AST), alanine aminotransferase(ALT) and alkaline phosphatase(ALP) from A. princeps were decreased by 33, 23 and $19\%$, respectively, compared to control. The activities of AST, ALT and ALP from A. argyi were decreased by 37, 33 and $26\%$, respectively. Total phenol contents were 10.2 mg/mL and 4.7 mg/mL in A. princeps, and A. argyi, respectively. Also, flavonoid contents were $6.1\;mg\%\;and\;3.6\;mg\%$ in A. princeps, and A. ar효i, respectively. Ethanol extract from A. argyi showed higher electron donating ability toward DPPH than A. princeps. A total of 31 volatile components(3 hydrocarbons, 10 terpenes, 5 carbonyls, 8 alcohols and 5 esters) were indentified in A. princeps, and A. argyi. The major volatile components of A. princeps were $\delta$-3-carene($2.2\%$) in terpenes and nerolidol($0.9\%$) in alcohols. The major volatile components of A. argyi were eugenol($1.4\%$) in alcohols and thyl pentadecanoate($1.1\%$) in esters.

Objectives: Osteoporosis, which occurs after menopause, is a kind of metabolic bone disorder. It develops when the bone mass begins to decrease radically, and its main symptoms are bone fracture and height-shortening. This thesis aims at what effects the Cuscutae Semen Extract(CSE) has on the prevention of osteoporosis in SD-rat that is caused by ovariectomy. Methods: The 24 female white rats, after removing their ovaries, were divided into the Normals, the Control group, and the CSE administrated group. For the next 8 weeks, distilled water to the normals and the control, and the CSE(45.9 mg/100 g) to the CSE administrated group were given in the mouths of them. After 8 weeks the rats were sacrificed. Weight, albumin, aspartate aminotransferase, alanine aminotransferase, total-cholesterol, triglyceride, phosphorus, calcium, tetraiodothyronine, estradiol, the weight of the femur, the amount of tibia ash, the area of trabecular bone, and the thickness of trabecular bone were measured. Results: The serum analysis shows that the calcium and phosphorous of the CSE administrated group significantly increased compared to that of the control group. Aspartate aminotransferase, alkalinephosphatase, total cholesterol, tetraiodothyronine of CSE group were decreased, but not so significant. Albumin, alanine aminotransferase, triglyceride and estradiol of the group showed the tendency to increase, but the significance wasn't admitted. Regarding the variation of bone, the femur weight and the ash content of tibia, CSE group was more increased than the control group but the significance wasn't admitted. The histological observation shows that the trabecular thickness was more increased than the control group, and trabecular area increased significantly compared to those of the control group. The number of osteoclast and osteoblast area of the CSE groups decreased significantly compared to those of the control group. Conclusions: From the result of the above study, CSE should be effective for the osteoporosis cure and precaution and deeper study through bedside and clinical demonstration is much needed from now on.

This study was carried out to investigate the effect of a beverage that contained Bulnesia sarmienti(BSP, 2.5%) on rats to which alcohol was administered. The treatment of the BSP group reduced the serum alcohol concentration to 52%, compared to 47% in the positive control(PC) group. Similar pattell1s were observed in the enhancement of alcohol dehydrogenase(ADH), acetaldehyde dehydrogenase(ALDH), alkaline phosphate(ALP), alanine aminotransferase(ALT), asparate aminotransferase(AST), total cholesterol(CHOL), ${\gamma}$-glutamyltrasferase(GGT), glucose(GLU), total bilirubin, and total protein(TP) in the serum. Also, in the BSP group, the lipoxidase(LPO), glutathion-S-transferase(GST), XO, catalase(CAT), and superoxide dismutase(SOD) were significantly reduced, compared to the CO and PC groups in the liver. The glutathione(GSH) activity increased in the BSP group, though. These results indicate that Bulnesia sarmienti extract can enhance alcohol metabolization activity.

Objectives: This study was designed to evaluate the efficacy of Changbudodam-tang on obesity by using high-fat diet rats. Methods: Rats were divided into five groups. Normal group: Normal diet, Control group: High-fat diet, Positive control group: High-fat diet+Dietamin 4 mg/kg/day, Changbudodam-tang-Low group: High-fat diet+Changbudodam-tang 250 mg/kg/day, Changbudodam-tang-High group: High-fat diet+Changbudodam-tang 500 mg/kg/day. Weight, food intake were measured every week. After 7 weeks, total cholesterol, high density lipoprotein-cholesterol, low density lipoprotein-cholesterol, Triglyceride, free fatty acid, aspartate aminotransferase, alanine aminotransferase, complete blood count were measured and messenger ribonucleic acid expression of adiponectin, peroxisome proliferator-activated receptor-γ, leptin were observed using Reverse transcription polymerase chain reaction of liver cells. Results: There was no difference in food intake between groups. Body weight tended to decrease compared with the Control group, but it wasn't statistically meaningfull. The total cholesterol, low density lipoprotein-cholesterol, Triglyceride, free fatty acid tended to decrease compared with the Control group. High density lipoprotein-cholesterol tended to decrease compared with the Control group, but it wasn't statistically meaningfull. White blood cell, red blood cell, hemoglobin, platelet, aspartate aminotransferase, alanine aminotransferase were not affected by Changbudodam-tang. The messenger ribonucleic acid expression of Adiponectin, peroxisome proliferator-activated receptor-γ, leptin, which are involved in the differentiation of adipocytes, was decreased compared with the Control group. Conclusions: Based on the results above, it is suggested that Changbudodam-tang can be applied to improving serum lipid levels in obese patients caused by high fat diets.

This study compared the results of hemolyzed samples and re-collected samples to investigate a hemolysis influence and an acceptable hemolysis index (HI). Before and after hemolysis, alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), amylase (Amy), direct bilirubin (D-bil), total bilirubin (T-bil), creatine phosphokinase (CK), gamma glutamyl transferase (GGT), iron, potassium (K), lactate dehydrogenase (LDH), magnesium (Mg), phosphorus (Phos), total protein (TP), and uric acid (UA) showed significant results in the paired t-test. LDH, K, iron, AST, CK, GGT, TP, Amy and Phos had a high correlation between the degree of hemolysis and the results of samples. When comparing Roche's cut-off HI with HI^QChigh obtained using quality control (QC) high standard deviation (SD), AST, D-bil, CK, and LDH were similar, but Amy, GGT, K, iron, Phos, and TP were lower than the cut-off HI of Roche, while ALP and ALT were higher. Some analytes which showed no significant results in the paired t-test, were found to have significant results in HI>200. Hence, it is suggested that the hemolyzed sample should be rejected if HI>200. Based on this study that some analytes were affected when HI<100, we recommend to set the standard of hemolysis starting from HI>50.

This study was carried out to investigate the effects of ash tree leaf extract (ALE) on acetaminophen (APAP)-induced hepatotoxicity in mice. Hepatoprotective effects were detected by biochemical analysis of hepatic enzymes and histopathological examination of the liver. BALB/c mice were divided into three groups: 'normal' control mice, APAP-treated control mice, and mice pretreated with ALE and treated with APAP. A single dose of APAP markedly increased levels of plasma aspartate aminotransferase (AST) and alanine aminotransferase (ALT). Light micrographs of liver cells stained with hematoxylin and eosin showed that APAP induced severe centrilobular necrosis, degeneration, and infiltration by inflammatory cells. Moreover, APAP caused the numbers of TUNEL-positive hepatocytes to increase and caused glycogen content to decrease as observed by Periodic acid-Schiff stain. However, pretreatment with ALE for 7 days prior to the administration of APAP significantly decreased plasma levels of AST and ALT. Histological findings demonstrated that ALE pretreatment alleviated APAP-induced liver damage, and induced the regeneration of liver tissue and restoration of glycogen. These results indicate that ash tree leaf extract exerts a protective effect against APAP-hepatotoxicity induced injury.
