In this study, the ameliorating effect of soybean embryos on the impact of alcohol consumption was investigated on rat hepatocytes and in reducing total serum cholesterol levels and total serum lipid levels. Liver histology and two clinically important enzyme markers, aspartate aminotransferase (AST) and alanine aminotransferase (ALT), of rats administered with both alcohol and soybean embryo were compared with a control group. The treatment regimen of soybean embryo significantly reduced the serum ALT and AST levels of the subjects, demonstrating the hepato-protective effects of soybean embryo. Electron microscopy indicated that the administration of soybean embryo preserved the important hepatocyte structures and prevented the presence of lipid droplets and secondary lysosomes. Furthermore, total cholesterol and total lipid levels were significantly reduced. These results indicate that treatment with soybean embryo can positively mediate the effects of alcohol on hepatocytes and general liver functions.

The purpose of this study was to investigate the effect of chloroform(CHC1$_3$) fraction of Alisma canaliculatum All. Braun et Bouche(Ac) with selenium(Se) on the plasma glucose and lipid levels in streptozotocin(STZ)-induced diabetic rats. Male Sprague-Dawley rats were divided into five groups. The normal and diabetic rats were separated into four groups: the STZ-control group, the Ac group, the Ac-Se group and the Se group. Diabetes was induced in the male rats by an injection of STZ into the tail vein at a dose of 45 mg/kg. The CHCl$_3$fraction of Ac(250 mg/kg) was administered orally for 14 days. The supplementation was achieved with the AIN-93 recommended diet by adding 2 mg/kg diet of selenium as Na$_2$SeO$_3$. which was prepared freshly everyday. The body weight, hematocrit(Hct), glucose, insulin, cholesterol, HDL-cholesterol, triglyceride(TG) and free fatty acids(FFA) concentrations in plasma were measured. The aminotransferase activities were also analyzed. The changes of body weight in the experimental groups were not significantly different from that of the STZ-control group, but diabetes hyperphagia accompanied changes with body weight loss in Ac-Se group. The levels of Plasma cholesterol were not significantly different among the experimental groups. The concentrations of FFA in the Ac-Se group increased significantly compared with the STZ-control group. The effect of Se alone significantly increased aspartate aminotransferase activity and alanine aminotransferase activity. The results showed that the treatment of CHCl$_3$fraction of Ac in combination with Se has no synergistic effect. There was a tendency for the plasma glucose levels to decrease when Se was administered into diabetic rats. Supplementation of Se in diabetic rats did not elicit a significant increase in plasma insulin levels and exhibited hypotriglyceridemic effect.

The present study was retrospectively designed to define whether preoperative levels of leukocytes and D-dimer are potentially useful factors in predicting perioperative outcomes of coronary heart disease (CHD). There was no relationship between preoperative leukocyte counts (Pre-OP leukocyte) and preoperative D-dimer levels (Pre-OP D-dimer). Pre-OP leukocyte counts each had positive correlation with cardiac troponin-I, creatine kinase-MB or C-reactive protein (cardiac markers) levels at preoperative and postoperative periods. Pre-OP D-dimer levels were positively associated with each cardiac marker at the same periods. Pre-OP leukocyte counts positively related with aspartate aminotransferase and alanine aminotransferase (liver markers), whereas Pre-OP D-dimer level positively or negatively correlated with bilirubin (liver marker), creatinine (renal marker) or glucose levels at preoperative and/or postoperative periods. Pre-OP leukocyte and Pre-OP D-dimer were inversely associated with Pre-OP high density lipoprotein cholesterol levels or left ventricular ejection fraction. Pre-OP leukocyte counts each had positive correlation operation duration and postoperative mechanical ventilation-time (PMVT), whereas Pre-OP D-dimer levels had positive relationship with PMVT, intensive care unit-staying period and hospitalization. The retrospective data suggest that Pre-OP leukocyte and Pre-OP D-dimer levels may be clinically useful factors for predicting perioperative outcomes in patients with CHD.

Changes in protein metabolism were studied in hemolymph and fat body on days 1, 3, 5 and 7 of the fifth-instar silkworm, Bombyx mori, exposed to lethal, sublethal doses and prevailing levels of fluoride in groundwater in Karnataka and Andhra Pradesh States of India. The total protein content indicated a depletion followed by a concomitant increase in accumulation of free amino acids. Concurrently, the activity of protease in both of the tissues was also increased. A steady enhancement in the activities of alanine aminotransferase and aspartate aminotransferase paralleled the elevation of glutamate dehydrogenase activity in the tissues studied. It is presumed, on the basis of these results, that the fluoride toxicity causes major changes in protein metabolism of the silkworms.

Previous studies have shown that methanol extract and its butanol fraction of Carthamus tinctorius L. Semen have the hepatoprotective effect on the CCl4-induced hepatotoxicity. The hepatoprotective effect of subfractions has been evaluated by analyzing blood and hepatocyte biochemical analyses and biotransformation enzyme analyses. Treatment of BS-5, subfraction has significantly decreased the activities of alanine aminotransferase and aspartate aminotransferase. In addition, the levels of cholesterol and triglyceride in liver have been decreased as compared with that of CCl4 treated rats. The hepatoprotective effect of BS-5, subfraction on the CCl4-induced hepatotoxicity would be mediated of the attenuation of the level of cytochrome P450 and the enhancement of the activity of glutathion S-transferase.

Purpose: We sought to examine the relationship between the clinical manifestations of nonspecific reactive hepatitis and respiratory virus infection in pediatric patients. Methods: Patients admitted to the pediatric unit of Konyang University Hospital for lower respiratory tract disease between January 1, 2014 and December 31, 2014 and who underwent reverse transcriptase polymerase chain reaction tests were examined. The patients were divided into those with increased levels of alanine aminotransferase (ALT) or aspartate aminotransferase (AST) and those with normal ALT or AST levels. Further, patients with increased ALT and AST levels were individually compared with patients in the normal group, and the blood test results were compared according to the type of respiratory virus. Results: Patients with increased ALT or AST levels had one more day of hospital stay, on average, compared with patients in the normal group ($5.3{\pm}3.1$ days vs. $4.4{\pm}3.0$ days, p=0.019). Patients in the increased ALT level group were younger and had a longer mean hospital stay, compared with patients in the normal group (p=0.022 and 0.003, respectively). The incidences of increased ALT or AST were the highest in adenovirus infections (6/24, 25.0%), followed by enterovirus (2/11, 18.2%) and respiratory syncytial virus A (21/131, 16.0%) infections. Conclusion: Nonspecific reactive hepatitis is more common among patients with adenovirus, enterovirus and respiratory syncytial virus infection, as well as among those infected at a younger age. Compared with AST levels, ALT levels are better indicators of the severity of nonspecific reactive hepatitis.

This study was performed to investigate the antioxidative effect of Ligusticum chuanxiong Hort extracts (LCE) against the hyperlipidemia of high-fat diet-fed obese rats. The rats were divided into the three groups (normal group, control group and sample group) to perform the experimental research. 1.5 ml/kg of LCE was intraperitoneally administered into the sample group for 21 days. The equal dose of 0.9% saline was intraperitoneally administered into the normal group and the control group. On day 22, they were anesthetized with ether and dissected. The levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT) were examined in serum of rats. Superoxide dismutase (SOD) was measured in mitochondrial fraction. Malondialdehyde (MDA), catalase (CAT), and glutamate peroxidase (GPx) were determined in liver homogenate. High-fat diet markedly increased the levels of AST, ALT and MDA, significantly decreasing those of SOD, CAT and GPx. But Ligusticum chuanxiong Hort-pretreatment decreased the levels of AST, ALT, and MDA. increasing those of SOD, CAT and GPx. These results demonstrated the antioxidative effects, suggesting that LCE could be the candidate for the functional material.

Background: Many herbal medications have been used to treat various liver diseases. But the concerns of herbal medicine induced liver injury also existed. In this respect, we would like to report several cases with imporved elevated liver aminotransferase after treating herbal medicine including Artemisia capillaris. Case Reports: We report four patients with elevated aminotransferase levels (ATLs), which indicate hepatocellular damages. After receiving herbal medicines therapy containing Artemisia capillaris as principal component (HMA), the patients' ATLs were improved. In the first case, the patient's ATLs decreased into normal range after administration of HMA, although they have not been improved with hepatotonics for a long period. In the second case, the patient's ATLs have been elevated after taking anticoagulants. The ATLs were improved with HMA without stopping anticoagulants. In the other two cases, the patients' ATLs were also improved after taking HMA. In addition, there were no changes of previous drugs for treating the corresponding underlying diseases and no adverse events during HMA applications. Result and Conclusion: The four patients received the herbal medicine containing Artemisia capillaris as principal component and showed improvement of ATLs. These cases suggest that HMA can be considered as alternative or complementary remedies to improve various liver diseases.

Purpose : The prevalence of obesity and nonalcoholic steatohepatitis(NASH) was increased in adolescents. This study was performed to observe the prevalence of elevated aminotransferase levels in adolescents and to assess the correlations between aminotransferase levels and obesity related parameters(body mass index, waist circumference, hip circumference, waist to hip ratio and insulin level). Methods : We obtained weight, height, waist circumference and hip circumference from 2,417 male and 1,219 female adolescents. Mean age was $15.7{\pm}0.7$ years old. We measured fasting insulin, aspartate aminotransferase(AST) and alanine aminotransferase(ALT). Obese and overweight were defined as body mass indices(BMI) of more than the 95th, and 85th-94th percentiles, respectively, for age and sex. Results : The number of adolescents with obesity is 324(8.9 percent). 414(11.4 percent) subjects belonged to the overweight group. The average ALT level of obese, overweight and control groups were significantly different(obese : $32.1{\pm}34.3U/L$, overweight : $19.6{\pm}13.6U/L$, control : $12.7{\pm}6.7U/L$, P<0.001). The average AST level was also different according to group(obese : $27.8{\pm}16.5U/L$, overweight : $22.8{\pm}8.6U/L$, control : $20.8{\pm}8.5U/L$, P<0.001). AST and ALT were correlated with anthropometric parameters and insulin level. After multiple regression analysis, waist circumference was the significant predictive value for AST(r=0.234, P<0.001). Waist circumference, BMI and insulin levels were significant predictive values for ALT(r=0.435, P<0.001). Conclusion : The prevalence of abnormal aminotransferase was higher in the obese and overweight groups than control group. Waist circumference was useful to predict abnormal aminotransferase levels.

CCl4 has been known as typical chemical which induce acute hepatitis accompanying increase in the levels of acute phase proteins in serum. In this study, after acute liver damage was induced by CCl4 in Sprague-Dawley rats, the levels of serum acute phase proteins were examined using 2-dimensional electrophoresis and lactic dehydrogenase (LDH), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels in blood were also examined at 1, 2, 3 days after the induction to confirm acute hepatitis.
