To evaluate an effect of liver damage on ethanol and xylene exposure, experiments on normal male rats of the S-D strain were performed in 4 groups. The biochemical results suggest that the ethanol group had significantly higher levels of AST, ALT, LDH and also, the xylene group had notably higher levels of AST, ALT, LDH along with MMHPA than those of the control groups. The levels of AST, ALT and LDH in the ethanol+xylene group were drastically higher than those in the control, ethanol and xylene groups. But, there were significantly lower ALP levels in the xylene and ethanol+xylene groups than both the control and ethanol groups. The histological features of rat livers treated with alcohol, or xylene proved to be normal. But the rat livers treated with ethanol+xylene showed mild to moderate necrosis and inflammation as well as minimal fatty changes. The results in this experiment suggest that liver functions decreased when medicated together with xylene and ethanol rather than solely with xylene.

The present study has been undertaken to investigate the effects of ginseng extract on the activities of several enzymes in serum of rats fed lard and alcohol. Thirty-five males of Sprague-Dawley strains weighed about 130 g were divided into 7 groups, each group receiving a different diet for 10 weeks; i.e. basal diet plus 15% lard, basal diet plus 5% alcohol, basal diet plus 5% ginseng extract, basal diet plus 15% lard and 5% ginseng extract. Determinations were carried out on the net weight gain, food efficiency ratio, weight of organs, and AST, ALT, lactate dehydrogenase, alkaline phosphatase activities in serum of rats. The results obtained were as follows:Rats given feed containing lard and alcohol showed significant decrease in net weight gain, but ginseng extract caused an increase in food efficiency ratio. Lard supplementation caused an increase in the weight of liver, kidney, spleen, but another groups did not. AST, ALT, ALP, LDH of serum were significantly increased in lard and alcohol containing group but ginseng extract feeding decreased enzyme activities compared to lard and alcohol containing group. The above results suggest that ginseng extract would prevent the metabolic disease of liver by preventing hyperlipemia caused by high fat diet.

The purpose of this study was to obtain reference values of serum chemistry in Korean rockfish (Sebastes schlegeli), 5 juvenile (n=25) and 3 broodstock (n=15) subpopulations which were differentiated by cultured method. Serum samples were analyzed for the following commercial clinical kits: total protein, albumin, glucose, AST (aspartate aminotransferase), ALT (alanine aminotransferase), total cholesterol, free cholesterol, LDH (lactate dehydrogenase) and ALP (alkaline phosphatase). Significant differences were observed in the values of total protein, albumin, total cholesterol, AST, ALT, LDH and ALP between juvenile and broodstock subpopulations. In the comparison of total protein, albumin, total cholesterol and ALP, broodstock subpopulations showed higher levels. On the other hand, increased AST, ALT and LDH were observed in juvenile subpopulations. These results indicate that cultured method are major contributors to health-related physiology of Korean rockfish, juveniles and broodstocks.

Purpose: The liver is the second most common organ injured by blunt abdominal trauma. The purpose of this study was to determine the utility of liver transaminase in screening blunt abdominal trauma patients for traumatic liver injury. Methods: We retrospectively reviewed the medical records of 231 patients who sustained blunt trauma and were at risk for traumatic liver injury between June 2009 and August 2010. All of them underwent a focused assessment with sonography for trauma (FAST) and abdominal computed tomography (CT). Based on the diagnosis of abdominal CT, patients were divided into two groups: group I with liver injury and group II without liver injury. We compared the two groups and calculated the sensitivity, the specificity and the predictive values of serum aspartate aminotransferase (AST) and serum alanine aminotransferase (ALT) by using multiple cutoff values. Results: Of 231 patients with no abdominal free fluid in the FAST, 33 had traumatic liver injury on abdominal CT. The mean AST and ALT levels in group I (311.6 IU/L and 228.1 IU/L, respectively) were significantly higher than the values in group II (48.4 IU/L and 35.6 IU/L, respectively). The cutoff to distinguish liver injury is 60 IU/L for AST and 58 IU/L for ALT, with 93.8% sensitivity and 79.8% specificity for AST, and 90.6% sensitivity and 87.4% specificity for ALT. Conclusion: We recommend that all patient with suspected blunt abdominal trauma be evaluated using serum liver transaminase as a screening test for liver injury even though no abdominal free fluid is shown on the FAST. If AST > 60 IU/L and/or ALT > 58 IU/L, abdominal CT was useful to confirm liver injury in this study.

Photobacterium damselae subsp. damselae and 4 Vibrio spp, V. anguillarum, V. splendidus, V. harveyi and V. ordalii, were isolated from the diseased olive flounders, Paralichthys olivaceus. The pathogenicity of the isolates were compared to mortality, blood biochemical contents, such as alanineaminotransferase(ALT), aspatate aminotransferase(AST), and cortisol level, and non-specific immune responses, nitroblue tetrazolium (NBT) reduction of macrophages and lysozyme activities of serum. The mortalities and levels of ALT, AST and cortisol of fishes infected with P. damselae were higher than those of others but significantly low in non-specific immune responses, NBT and lysozyme activities. These results suggest that P. damsela might produce damselysin having high hemolytic and phospholipase activities, correlated with the pathogenicity. P. damsela could also make an obstruction of internal organs, following increasing in the level of ALT and AST, and depression in host immunity caused by induced high levels of cortisol.

The antilipidperoxidative and hepatopreventive effects of Houttuynia cordata extract(HCE) were investigated at the level of liver homogenates and serum of SD rats intoxicated EtOH(3g/kg for 3days). We measured MDA(malondialdehyde) in the live. homogenate, AST(1-aspartate-2-oxoglutarate aminotransferase) and ALT( 1-alanine-2-oxoglutarate aminotransferse) in the serum. The analysis of the measurement indicated that HCE reduced MDA, ALT and AST significantly and their reduction was in relation to dose dependence. In rat liver homogenate intoxicated with EtOH, HCE treatment group inhibited lipidperoxidation by 50-75%. In rat serum intoxicated EtOH, HCE inhibited AST and ALT by 40-70%.

Objectives: In order to determine the effect of CPs, experimental studies were performed in hyperlipidemia humans. The contents of serum total cholesterol, TG (triglyceride), LDL cholesterol, HDL cholesterol, AST/ALT and BUN/creatinine were measured. Methods: We made a comparative study of total cholesterol, TG (triglyceride), LDL cholesterol, HDL cholesterol, AST/ALT and BUN/creatinine during one month off and on for twenty patients with hyperlipidemia who visited Gunpo Oriental Medical Center of Wonkwang University from December 2002 to July 2003. Results: The following result were obtained: 1. The serum TG and total cholesterol of patients who took CPs for one month showed significant (p<0.01) decrease. 2. The serum HDL-cholesterol and LDL-cholesterol of patients who took CPs for one month showed significantly increase in HDL, and decrease in LDL (p<0.05). 3. The serum AST/ALT and BUN/creatinine of patients who took CPs for one month showed no significant effects. Conclusions: According to the results mentioned above, the effects of CPs on serum triglyceride and total cholesterol of hyperlipidemia patients were significantly confirmed for decreasing effects.

We evaluated whether liver markers such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma-glutamyltranspeptidase (GGT), and bilirubin have a relationship with other physiological factors in the normal (n=115) and fatty liver subjects (n=122) and there are differences between the two populations. Body indices were higher in the fatty liver group than in the normal group. Liver markers and blood pressure (BP) were greater in the fatty liver group than in the normal group. AST and ALT levels were positively correlated with body indices in the fatty liver group, but not in the normal group. AST, ALT and GGT levels in the fatty liver group had positive relationship with cardiovascular indices (CI). ALP and bilirubin levels were negatively associated with some of CI. Liver markers were negatively or positively correlated with inflammatory markers, thyroid hormones, or several biochemical markers levels. These findings suggest that abnormal changes in liver markers may be useful tool for diagnosis or prognosis of development of cardiovascular and/or inflammatory diseases as well as metabolic syndrome.

The purpose of this study was carried out to investigate the effect of scoparone(6, 7-dimethoxyco-umarin) on liver function. Sprague-Dawley rats were treated with scoparone at a dose of 20mg/kg body weight for 5 days. Hepatic bile flow, liver weight, BSP(bromosulfophthalein) biliary excretion, alanine aminotransferase(ALT) and aspartate aminotransferase(AST) activities, malondialdehyde production and lactate dehydrogenase(LDH) release were assayed. Among them, ALT and AST activities, malondialdehyde production and LDH release were assayed by using primary hepatocyte cultures at a concentration of 0.1mg/ml. Scoparone treatment had no effect on liver weight and hepatic bile flow. Scoparone treatment not only increased BSP biliary excretion, but also recovered the decreased BSP biliary excretion by CCl4, Also scoparone significantly decreased with the increases of ALT and AST activities, malondialdehyde production and LDH release induced by CCl4. These results suggested that scoparone could protect the liver damage by chemicals via promoting the liver excretory function.

The purpose of this study was to probe the influences of NaF oral administration on a dose-effect relationship between fluoride levels of serum enzyme activity such as alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and lactate dehydrogenase (LDH) in rats fed experimental diets for 5 weeks. All groups increased the activity of serum ALP, AST, ALT, and LDH levels with increasing NaF. In addition the fluoride levels of serum and organ tissues (liver, brain, heart, lung, kidney) in oral NaF groups (NF3~NF50) were significantly increased by adding sodium fluoride in comparison with normal diet group (ND) (p<0.05). These results, a high concentration of sodium fluoride was determined that the toxicity to various organ tissues.
