The purpose this study was to investigate the influences of 5% turmeric (Curcuma longa L.) supplementation on enzyme activities such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), amylase, lipase and catalase in serum of dyslipidemic rats. Sprague-Dawley (SD) rats (24 male) were divided into four groups, namely the ND group (normal-nondyslipidemic diet), NT group (normal-nondyslipidemic diet+5% turmeric), DD group (control-dyslipidemic diet), and DT groups (dyslipidemic diet+5% turmeric). Serum concentrations of blood urea nitrogen (BUN), creatinine and uric acid were significantly decreased (p<0.05) by turmeric supplementation diet. The activities of AST, ALT, ALP, LDH, amylase and lipase in sera of turmeric diet group were significantly decreased (p<0.05). The catalase activity in serum of turmeric supplementation group was significantly increased than dyslipidemic diet (p<0.05). In vivo experiment with dyslipidemic rats showed that ingestion of turmeric were effective in kidney and hepatic functional enzyme activities. Which suggests that turmeric material could be used for further studies as a potential source for nutraceutical foods.

The present study was conducted to investigate the effects of beverages containing fermented Akebia quinata extracts on alcoholic hangover. For this study, 25 healthy young men were recruited. All participants consumed 100 mL of water (placebo), commercial hangover beverage A or B, fermented A. quinata leaf (AQL) or fruit (AQF) extract before alcohol consumption. After 1 h, all participants consumed a bottle of Soju, Korean distilled liquor (360 mL), containing 20% alcohol. Blood was collected at 0 h, 1 h, 3 h, and 5 h after alcohol consumption. The plasma alanine transaminase (ALT) activity was highest in the placebo group. Compared with the control group, the AQL and AQF groups showed decreased ALT activity at 5 h after alcohol consumption. Plasma ethanol concentration was increased after alcohol intake and peaked at 3 h after alcohol consumption. Compared with the control group, the A group showed a higher plasma ethanol concentration at 1 h (P<0.05). At 3 h after alcohol consumption, the AQF group showed the lowest mean plasma ethanol concentration compared to the other groups; however, there were no statistical differences. After 5 h of alcohol consumption, the AQL and AQF groups showed lower plasma ethanol concentrations compared with the B group. The sensory evaluation score for the fermented A. quinata fruit extract was lower than for the commercial hangover beverages. In conclusion, the present intervention study results suggest that fermented A. quinata extracts alleviate alcoholic hangover and reduce plasma ethanol concentrations.

Hepatic ischemia-reperfusion injury (HIRI) is linked with high mortality rate. Several agents have been developed so far to reduce the risk of HIRI. In this study, we investigated the effects of combined treatment of Ginko biloba leaves extract and vitamin C (GLEVC) on hepatic ischemia-reperfusion injury. To explore the protective effects of GLEVC on HIRI rats model were tested. After the development of HIRI by using clamping method rats were then randomly divided into four groups. Different doses of GLEVC were administered in HIRI rat model. The level of ALT, AST, SOD and MDA content in serum were detected in HIRI groups. Moreover, the activity of SOD, content of MDA, and GSH in hepatic tissue were also examined. Bcl-2 and Bax protein expression were detected by immunohistochemical staining method. Compared with sham group, GLEVC has the protective effect on the HIRI-induced model. Level of ALT, AST, and MDA in blood were significantly lower in GLEVC group compared with HIRI-induced group. Moreover, SOD activity and GSH were increased in GLEVC group whereas MDA content was reduced by GLEVC treatment. Furthermore, HIRI-induced Bax protein was reduced upon GLEVC treatment, whereas Bcl-2 protein expression was enhanced. These results demonstrate that GLEVC treatment may provide potential ameliorative therapy by reducing damaged signaling mechanism in hepatic ischemia/reperfusion injury model.

The prevalence of obesity in children has steadily risen during recent years in developed countries. Child obesity has become a major concern to health providers since it has grown to epidemic proportions over the past few decades. This study was conducted to investigate the biochemical status, dietary habits and life styles according to the obesity degree among obese children residing in the Gyungbuk area. The subjects were 148 elementary school students (boy 103, girl 45) and classified as mildly obese (n = 56), moderately obese (n = 61) and severely obese (n = 31) by the obesity index. The average body weight and height increased significantly according to the obesity degree (p < 0.05, p < 0.001). Serum cholesterol concentration came under the normal level in all groups. Serum AST activity increased according to the obesity degree but it was not significant. Serum ALT activity increased according to the obesity degree (p < 0.05). Dietary habit score was lower significantly according to the obesity degree (p < 0.01). Life style of the subjects was significantly different for the level of 'healthy state (p < 0.05)', 'body perception (p < 0.01)', 'watching TV and video (p < 0.05)', 'normal sleeping hour (p < 0.05)' and 'degree of stress (p < 0.05)' according to the obesity degree. A positive relationship between obesity index and blood pressure, ALT has been shown in the subjects. Obesity index and dietary habit scores were negatively associated. Therefore, these results suggest that a practical nutrition-exercise education program for the prevention of child obesity should be provided to elementary school children.

To observe the potential hepatoprotective effects of Gongjin-dan on the acute ethanol (EtOH)-induced liver damages in C57BL/6 mice with its possible action mechanisms. EtOH-mediated acute hepatic damages were induced by oral administration of EtOH total 3 doses. The changes on the body weight, liver weight, albumin, TG, AST, ALP, ALT, hepatic TG contents, hepatic antioxidant defense system, TNF-α, CYP 2E1 activity and mRNA expressions of hepatic lipogenic genes - SREBP-1c, SCD1, ACC1, FAS, PPARγ and DGAT2 or genes involved in fatty acid oxidation - PPARα, ACO and CPT1 were observed with final liver histopathological inspections after 15 days of continuous administration of silymarin 200 mg/kg, Gongjin-dan (GJD) 400, 200 and 100 mg/kg. The results were compared with silymarin 200 mg/kg treated mice. Marked decreases of body and liver weights, increases of serum AST, ALT, Albumin and TG levels, hepatic TG contents, TNF-α level, CYP 2E1 activity and mRNA expressions of hepatic lipogenic genes or decreases mRNA expressions of genes involved in fatty acid oxidation were observed with histopathological changes related hepatosteatosis increases of immunolabelled hepatocytes, as the results of a binge drinking of EtOH in the present study. Also destroys of hepatic antioxidant defense systems were demonstrated in EtOH control mice as compared with intact vehicle control mice, respectively. The results suggest that oral administration of 400, 200 and 100 mg/kg of GJD favorably protected the liver damages from acute mouse EtOH intoxications.

해혈 및 진동 효과를 가진 APAP는 과량 복용시 CYP-450에 의해 독성 유발 물질인 NAPQI로 대사되어 간장과 세포막을 붕괴시켜 세포 내 calcium 유입을 증가시킴으로서 간세포의 괴사를 일으킨다. DIL은 CYP-450 작용을 억제하는 것으로 알려진 칼슘채널차단제이다. 따라서 본 연구에서는 APAP 300mg/kg을 경구 투여한 후 3, 6. 9 및 12시간에 DIL을 복상내로 투여하여 DIL이 APAP의 독성에 미치는 영향을 조사하였다. APAP 투여 12시간후 DIL 투여군에서 혈청과 간조직의 생화학 분석과 조직학적 관찰에서 간손상의 개선 효과가 확인되었으며, 이는 세포내로의 calcium 유입과 지질과산화의 억제 및 GST의 활성도 증가에 기인한 것으로 보인다. 그러므로 APAP 과량 복용 12시간 후의 DIL 투여는 간손상의 억제에 효과적일 것으로 사료된다.

Objectives : The effect of pear extract with Daekumeumjagami and vitamin C medication(PDV) on alcohol metabolism and hepatic injury was assessed following hepatic injury induced by alcohol in mice. Methods : The model of alcoholic hepatic injury was established by orally administration with 3 g/kg 25% alcohol in mice. PDV was orally administrated once a day for 5 days. Mice were randomly divided into 5 groups : normal group, control group, and PDV groups (PDV-A, PDV-B and PDV-C). The activities of aspartate amino transferase (AST) and alanine amino transferase (ALT) and alcohol dehydrogenase (ADH) in serum, superoxide dismutase (SOD) and catalase in liver were determined after alcohol exposure. Results : Compared with control group, treatment with PDV-B and PDV-C significantly elevated activities of ADH. Moreover, the index of hepatic injury in serum was significantly decreased by treatment with PDV-B and PDV-C in ALT activity and PDV-C in AST activity. Additionally, enhanced catalase activities in liver was found in PDV-C treated mice after exposure to alcohol. Also, WBC in blood was significantly lower by treatment with PDV-B and PDV-C. Conclusions : This study suggests that PDV treatment could enhance alcohol metabolism, and prevent hepatic injury after alcoholic hepatic injury and that this effect is likely related to its modulation on the alcohol metabolizing and antioxidant enzymes.
