We studied a comparison of the concentration of biochemical markers in sera of patients hospitalized with high fever (n=296) in Jeonbuk province during the last 2 years (2008 to 2009). The patients were divided into three patient groups of viral hemorrhagic fever (VHF) patient group tested positive for Hantavirus (n=53), leptospirosis (LEP) patient group tested positive for Leptospira interrogans (n=137) and scrub typhus (TSU) patient group tested positive for Orientia tsutsugamushi (n=106). We analyzed the concentration of ALP, AST, ALT, blood urea nitrogen, creatinine and glucose and compared the mean levels of them to normal range, the first sample and last sample. The frequencies of abnormal patient elevated above the upper limit of normal for ALP, AST and ALT were 18~43.4%, 78~97% and 62.3~92.7% in patient groups, and 24.5~47.4% (total protein) and 13.2~50.0% (albumin) of patients in patient groups had decreased below the lower limit of normal. The patients showed higher abnormal levels of glucose in patient groups were 58.5% (viral hemorrhagic fever patient group), 66.4% (leptospirosis patient group), 71.7% (scrub typhus patient group) and 66.9% (total patient group). There were significant difference between the first sample and the last sample in the mean levels of AST (decreased 22.2% in viral hemorrhagic fever patient group, 30.2% in leptospirosis patient group, 20.4% in scrub typhus patient group and 24.1% in total patient group), BUN (43.0% in viral hemorrhagic fever patient group, 41.6% in leptospirosis patient group, 47.4% in scrub typhus patient group and 43.0% in total patient group) and glucose (20.2% viral hemorrhagic fever patient group, 17.9% in leptospirosis patient group, 18.6% in scrub typhus patient group and 18.9% in total patient group) in the first sample and the last sample. According to these results, those diseases may cause liver damage and have high concentration of ALP, AST, ALT and glucose in blood even though the patients get out of the hospital.

After exposing Olive flounder and Korean rockfish to the concentration ranges of control (0 mg/L), 100 mg/L, 250 mg/L, 500 mg/L, and 1,000 mg/L, to investigate the physiological properties of suspended load on fish AST/GOT, ALT/GPT, ALP and cortisol were analyzed. As a result of the analysis, the AST/GOT, ALT/GPT, ALP and cortisol values were higher in the suspended load concentration section than in the control group. After artificial infection with S. parauberis for Olive flounder and V. harveyi for Korean rockfish exposed to suspended load, the survival rate was higher in the control group than in the suspended load concentration section. These results are related to the previously study results of suspended load that adversely affect fish, suggesting that suspended load affects the health of fish.

This study was conducted to investigate the effect of Makgeolli and Makgeolli precipitate on hepatotoxity and the serum lipid content in rats. First, we investigated the effect of Makgeolli and ethanol on the progress of alcoholic fatty liver. The effect of Makgeolli precipitate on carbon tetrachloride ($CCl_4$)-induced hepatotoxicity in the rats was then studied. Indicators of the health status of the experimental period, the body weight gain in ethanol-treated group tended to be lower than those in the control and the Makgeolli-treated groups. The weight of the liver tissue decreased significantly following the administration of ethanol. However, this was not seen following the administration of Makgeolli. The activities of serum aspartate transaminase (AST) and alanine transaminase (ALT) were decreased in the Makgeolli group compared to the ethanol group. Serum cholesterol concentrations increased in the ethanol group, but decreased in the Makgeolli-treated group to an equal volume of the ethanol-treated group. The serum HDL-cholesterol content was significantly higher in the Makgeolli group than in the ethanol group. Analysis of the impact of the Makgeolli precipitate on toxicity induced by $CCl_4$ in the liver showed that the $CCl_4$ treatment significantly increased the activities of serum ALT and AST. However, the levels of cholesterol and triglyceride in serum were decreased. The $CCl_4$ treatment increased the activities of AST and ALT. However, the raw Makgeolli precipitate decreased their activities. Moreover, raw Makgeolli precipitate significantly reduced the $CCl_4$-induced elevation of serum lipids more than heated Makgeolli precipitate. These results suggest that raw Makgeolli precipitate may exert a protective effect against $CCl_4$-induced liver injury by preventing lipid peroxidation.

Objectives The recent prevalence rate of obesity in children is increasing, but so far the majority of ongoing research is focused on obesity in adults. Even comparison studies between obesity in adults and in children are insufficient at this stage. Thus, our research will investigate the characteristics of obesity in children based on the comparison with adults. Methods The blood levels including glucose, cholesterol, AST, ALT of obese children and obese adults were compared and analyzed. Results From comparison studies, the levels of glucose, cholesterol, ALT in adults were higher than in children. In order to take account the age differences, only the rate of abnormal levels based on the reference range were compared. As a result, the abnormal rate in blood cholesterol level was higher in children. Conclusions Childhood obesity may develop complications at early age and has high potential risk to result in adult obesity as well. Therefore, child obesity needs to be treated with more caution and careful attention.

Toluene is mainly metabolized in liver by oxidative pathway. Oxigen free radicals occur through the process of toluene metabolism Therefore it causes tissue and cell min by the oxygen free radicals from the metabolism of toluene. Melatonin acts as a highly efficient free radical scavenger that protects cells from damage by oxygen free radicals. To test this hypothesis, toluene hepatotoxicity was induced by an abdominal injection of toluene. To see if the melatonin protects the rat's liver, melatonin was administrated orally, at the time of each toluene injection. Aspartate aminotransferase(AST), alanin aminotransferase(ALT), latic dehydrogenase(LDH) and alkaline phosphatase(ALP) levels in serum were measured to estimate hepatic function. Malondialdehyde(MDA), which gives an indirect index of oxidative injury was also measured. Hippuric acid is the last metabolic Production of toluene was measured by HPLC. There were significantly higher in AST, ALT, LDH, MDA and hippuric acid in toluene group, but there were no significant difference in melatonin group except ALT and hippuric acid. There was significantly lower in ALP level in toluene group, but there was no significant difference melatonin group, suggesting a significant hepatotoxicity due to oxygen free radicals through the process of toluene metabolism Melatonin treatment significantly protected hepatic function and free radical-mediated injury in the liver against toluene-induced changes. Accordingly, this study shows that melatonin is helpful in protecting liver injury by acute toluene intoxication.

Objectives : This study was carried out to research the protective effects of Sagunja-Tang(SA) through in vivo experiments, and tried to investigate the relation between oxidation of liver tissues and deficiency of Qi. Methods : Acute liver injury which initiated from free radical induced by $CCl_4$, were applied to mice and metabolic data were obtained. In order to measure the degree of liver injury, serum level of alanine aminotransferase(AST), aspartate aminotransferase(ALT), creatinine, blood urea nitrogen(BUN), total protein(TP) and glucose were measured. Lipid peroxidation of liver slice was examined by measuring malondialdehyde(MDA), a product of lipid peroxidation. Results : SA had protective effects on $CCl_4$ induced acute liver injury by decreasing serum level of ALT. Kidney injury was induced by injection of $CCl_4$ too, and SA protected kidney injury by decreasing serum level of creatinine and BUN. Conclusions : Through this study, we found that SA have healing effects on liver and kidney injury of $CCl_4$ induced oxidative stress that is similar to deficiency of Qi. And further studies have to be followed to certify the mechanisms.
