Sera from male Spague-Dawley rats, exposed to $30\\pm 0.5^\\circ C$ for 240 hours or $33\\pm 0.5^\\circ C$ for 64 hours, were assayed for the activities of serum glutamic oxaloacetic transaminase(SGOT) and serum glutamic pyruvic transaminase(SGPT) at various time during the heat exposure. 1. When compared to control animals maintained at $23\\pm 1^\\circ C$, the animals exposed to $30\\pm 0.5^\\circ C$ ro $33\\pm 0.5^\\circ C$ showed a significant increase in SGOT and SGPT activities, 2. The SGOT activity incressed at 16 and 72 hours after the exposure to $30^\\circ C$, and at 30 and 64 hours after the exposure to $33^\\circ C$. After 72 hours, the activity returned to the initial value in case of $30^\\circ C$ exposure. 3. The SGPT activity increased significantly as early as 4 hours after the exposure to $30^\\circ C$ or $33^\\circ C$. It was also high at 16 hours after the exposure. The activity was also high at 72 hours and at 64 hours after the exposure to $30^\\circ C$ and $33^\\circ C$ respectively. After 144 hours, SGPT level increased slightly in the case of $30^\\circ C$ exposure. 4. The activities of SGOT and SGPT were significantly higher in rats exposed to $33^\\circ C$ at 16, 30, and 64 hours than those exposed to $30^\\circ C$. 5. It may be inferred from above data that the prolonged heat exposed rat has the abnormal metabolism of transamination.

A benzomorphan derivative, pentazocine has both opioid agonistic actions and weak narcotic antagonistic activity. In this paper, authors attempted to study the dose response of pentazocine on the blood sugar level, serum transaminase and alkaline phosphatase activity in rabbits. Eighteen rabbits were devided into 3 groups, and each group were injected with pentazocine 5mg, 15mg, and 30mg/kg respectively. And metabolic effects were investigated measuring the change of blood sugar contents, serum transaminase (S-GOT, S-GPT) activities and alkaline phosphatase activities in rabbits. The results were obtained as follows; 1. Pentazocine significantly increased the blood sugar content in rabbits. 2. Pentazocine significantly increased the serum GOT activity but in the serum GPT activity, it significantly increased in large dose. 3. Pentazocine significantly increased serum alkaline phosphatase activity.

The effects of an antimetabolite, 6-aminonicotinamide (6-AN) on the levels of enzymes and metabolites in rabbit serum were investigated. The intraperitoneal administration of 6-AN (multiple doses of l5mg/kg body weight) gave tise to a remarkable increase in glucose and cholesterol levels but did not exert any appreciable influence on the concentration of albumin and total protein. Alkaline phosphatase activity was significantly reduced by administration of 6-AN, whereas creatine phophokinase, serum glutamic oxaloacetate transaminase and serum glutamic pyruvate transaminase activities were matkedly enhanced. Nevettheless, the levels of Ca, P, Na, K, Cl and Co were not affeded to any extent by 6-AN.

OBJECTIVES : Schizandra chinensis is well known for its efficacy at liver function reinforcement, relieving thirst and recovery from fatigue. In this study, we examined the effects of sports drink containing Schizandra chinensis on serum metabolic substrate, electrolyte, stress indicators, related-enzyme and exercise performance, rectal temperature, and heat shock proteinb70 (HSP70). METHODS : Elite long-distance runners (male, 21.3yrs, n=16) were selected and divided into two groups; an experimental group (EXP, n=8) and a control group (CON, n=8). A beverage containing Schizandra chinensis was supplemented 3 times per day to EXP for 4 weeks. Serum biochemical elements (glucose, lactate, total cholesterol, triglyceride, high density lipoprotein cholesterol, glutamate oxaloacetate transaminase, glutamate pyruvate transaminase, creatinine, creatine phosphokinase, lactate dehydrogenase, blood urea nitrogen, Na, K, Cl) were analyzed by auto blood analyzer. Exercise performance was measured by treadmill exercise test, HSP70 was detected by electrophoresis and Western blotting, and rectal temperature was measured by rectal temperature probe. RESULTS : Administration of the beverage increased significantly the rest level of blood Na, Cl and glucose and decreased significantly lactate dehydrogenase, glutamate oxaloacetate transaminase. No difference was found in exercise performance, rectal temperature increment or HSP70 concentration between groups. CONCLUSIONS : Administration of a sports drink containing Schizandra chinensis altered blood glucose, lactate dehydrogenase, glutamate oxaloacetate transaminase, Na and Cl levels.

In the present study, Thespesia populnea (Malvaceae) bark was extracted with methanol and water. The extracts were vacuum dried to yield the respective methanol (MET) and aqueous extract (AET). The extracts were evaluated for hepatoprotective activity against carbon tetrachloride $(CCl_{4})$ induced liver damage at 2 dose levels (250 and 500 mg/kg). The biochemical parameters observed in serum were total bilirubin, alkaline phosphatase (ALP), serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT) levels and total protein. Aspartate transaminase (AST), alanine transaminase (ALT) and total protein levels in liver were also evaluated. Histopathological study on the liver tissue was also performed. The extracts exhibited dose dependent reduction in total bilirubin, ALP SGOT, SGPT, AST, ALT and increase in total protein (serum and liver) levels. The extracts also exhibited only mild hepatocytic damage compared to the $CCl_{4}$ Treated group. MET was found to exhibit higher hepatoprotection than AET.

This study was performed to investigate the effect of Mori Folium and Crataegus pinnatifida leave extracts on liver damage induced by CC1$_4$ in rats. 30％ and 60％ methanol extracts of Mori Folium and Crataegus pinnatifida leaves were administered orally at the dose of 10 mg/kg on every day for 6 days and liver damage was induced by intraperitoneal injection of $CCl_4$ (0.4 ml/kg) on 6th day. 30％ Methanol extracts of Mori Folium treated group showed significant protective effect on hepatotoxicity with the lowest Glutamic Oxaloacetic Transaminase (GOT) and Glutamic Pyruvic Transaminase (GPT). The low density lipoprotein (LDL) levels of 30％ methanol extracts of Mori Folium and Crataegus pinnatifida leave and 60％ methanol extracts of Mori Folium treated groups were significantly lower than normal group, respectively. In particular, LDL level of 30％ Mori Folium extracts treated group was significantly decreased compared to $CCl_4$ treated group. These results support that Mori Folium and Crataegus pinnatifida leave extracts are hepatoprotective effects against hepatotoxicity induced by $CCl_4$.

Effects of restraint stress and its modulations by ursodeoxycholic acid(UDCA) were evaluated on some biochemical and biophysical parameters in rats. Restraint stress induced elevations in blood alkaline phosphatase (ALP). cholesterol (CHOL), aspartate transaminase (GOT), alanine transaminase (GPT), lactate dehydrogenase (LDH) levels. It was also caused adrenal hypertrophy, decrease in weight of spleen and contents of ascorbic acid in stressed rats. As a results, stress indicators such as spleen, ascorbic acid, GOT, GPT, LDH were fastly changed after imposing stress, but those such as ALP, CHOL, adrenal were induced relatively later. UDCA was tested if it has an inhibitory effect against 18-hr restraint induced stress. UDCA lowered ALP, CHOL, LDH level and also effectively elevated the ascorbic acid contents in 25 mg/kg dosage of UDCA. In organ weights. the restraint stress induced increases in spleen and adrenal were attenuated by UDCA in 50 mg/kg dosage. However. stress-induced GOT and GPT levels were unaffected by UDCA.

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.

In this study, the anti-lipidperoxidative effects of G009, a polysaccharide extracted from Ganoderma lucidum IY009, was determined in ascorbic acid-$Fe^{2+}$-adenosine 5-diphosphate-intoxicated rat. In a model of ascorbic acid-Fe$^{2+}$-adenosine 5-diphosphate-induced hepatotoxicity in rat, G009 exhibited anti-lipidperoxidative effect in rat liver homogenate, and that malondialdehyde values of the liver homogenate inhibited from 48.1% to 74.8% in comparison to controls (p<0.05). The malondialdehyde formation in serum inhibited 66.5% at 100 mg/kg of G009. Also, serum levels of glutamic oxaloacetic transaminase and glutamic pyruvic transaminase in peroxidizer-induced rats treated with G009 was decreased compared with control. Especially, the formation of lipid peroxides in serum was related to glutamic pyruvic transaminase levels. These results suggest that G009 has a protective effect on ascorbic acid-$Fe^{2+}$-adenosine 5-diphosphate-induced hepatic injury through an inhibition of lipid peroxidation in liver.r.
