Isoflurane and enflurane are currently used on orthognathic surgery in Korea. Since starting to use enflurane and isoflurane in orthognathic surgery, we have questioned their effect on liver function. Many studies have reported liver function after enflurane and isoflurane anesthesia. Although both enflurane and isoflurane are less hepatotoxic than halothane, some cases of liver dysfunction have been reported after enflurane and isoflurane anesthesia. And, we know that isoflurane is less hepatotoxic than its predecessors, enflurane. But, fulminant liver failure and necrosis were also reported after isoflurane anesthesia. The purpose of this study was to compare immediate liver function in healthy orthognathic surgical patients receiving enflurane or isoflurane anesthesia. To assess the effect of enflurane and isoflurane on liver function, we measured pre-and post-operative serum concentrations of aspartate aminotransferase(AST), and alanine aminotransferase(ALT), alkaline phosphatase(ALP), total bilirubin(Tbil).

Obese children have increaed in Korean in recent years as socieconomic status have got more higher than past years. Obese children have many health problems and some kinds of complications. Obese patients who have fatty liver with abnormal liver function should be managed with weight control. This study was intended to investigate the effect of weight control on hepatic abnormalities of obese children with fatty liver. We managed 6 obese children who had fatty liver with abnormal liver finction for weight control containing behavior modification, diet and exercise during 3 months. After 3 months, we compared body weight, liver function test, dietary intake and exercise. Body mass index(BMI) showed significant decrease from 28.1$\pm$2.3kg/$m^2$ to 26.2$\pm$1.7kg/$m^2$ (p<0.01). Aspartate aminotransferase(AST) showed significant improvement from 56$\pm$15IU/l(p<0.01). Alanine aminotransferase(ALT) also showed significant improvement from 108$\pm$38IU/l to 33$\pm$9IU/l(p<0.01). Therefore if we can rule out the other causes of hepatic abnormalities in obese children with fatty liver, these patients showed benefit by weight control as it can improve both obesity and liver functions.

To evaluate the impact of parathion on aquatic organisms, a freshwater bagrid catfish (Pseudobagrus fulvidraco) was exposed to sublethal concentrations $(63,\;95,\;190\;and\;380\;{\mu}g/L)$ of parathion, organophosphorus pesticide for 30 days. Glucose level in the serum of the bagrid catfish was significantly increased than that of control groups in the $190\;{\mu}g/L$ concentration at 30 days and in the $380\;{\mu}g/L$ concentration after 10 days. Bilirubin level was significantly increased in the $190\;{\mu}g/L$ concentration at the end of the experiment. After 10 days, a significant differences of lactate dehydrogenase (LDH) and alkaline phosphatase (ALP) activity increased in the ${\geq}190\;{\mu}g/L$ and $380\;{\mu}g/L$ groups. Though cholesterol concentration was stable, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities in serum were significantly reduced in the $190\;{\mu}g/L$ at 10 days and in the $380\;{\mu}g/L$ concentration at the end of the experiment. In conclusion, if P. fulvidraco was chronically exposed to ${\geq}190\;{\mu}g/L$ concentration of parathion, the hematological changes may be induced due to the stress response.

This study the effects of Cu exposure on biochemical factors in the hemolymph and hepatopancreas of the abalone $Haliotis$ $discus$ $hannai$. Abalone were exposed to 0, 5, 10, 20 and 40 ${\mu}g/L$ Cu for 4 weeks. The calcium concentrations in hemolymph were decreased significantly on exposure to 20 and 40 ${\mu}g/L$ Cu after 2 weeks. The aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) activities in abalone hemolymph were markedly elevated after exposure to 40 ${\mu}g/L$ Cu for 4 weeks. The hepatopancreas superoxide dismutase (SOD) and catalase (CAT) activities were also significantly increased by exposure to 20 ${\mu}g/L$ Cu for 4 weeks. These biochemical factors may represent a convenient method of monitoring heavy metal pollution in coastal areas. From these results, we conclude that a high copper concentration (40 ${\mu}g/L$) in water may curtail hemolymph homeostasis and anti-oxidative reactions in abalone.

Biliary atresia (BA) is the result of fibrosing destructive inflammatory process affecting intrahepatic and extrahepatic bile ducts, which lead to cirrhosis and portal hypertension. Kasai portoenterostomy has been the standard operative procedure in biliary atresia. Recently, there has been remarkable increase in the survival rate in cases of BA. However, long-term survivors are not clearly evaluated in Korea. To define long-term prognosis factors of patients who underwent surgery for BA, a retrospective study was undertaken of 10 (37 %) patients surviving more than 10 years among 27 patients who underwent one of Kasai procedures between 1981 and 1995. Hepatomegaly was present in 4 and splenomegaly in 7 patients. Serum bilirubin was normalized at 1 year after operation. Aspartate aminotransferase (AST, GOT), Alanine aminotransferase(ALT, GPT) were normalized at 12 years and alkaline phosphatase(ALP) was normalized at 13.5 years. Cholangitis developed mainly within 5 years after operation so close follow up is needed. Life long follow-up is needed because of progressive deterioration of liver function even after 10 years.

The effects of godulbaegi(Ixeris sonchifolia H.) powder on body weight gain, lipid and protein concentrations, and enzyme activities were studied in growing male rats for 4 and 8 week. The fats (Sprague-Dawley) were fed diets containing 5% godulbaegi or without. The body weght gain, food efficiency ratio, protein efficiency ratio, hemoglobin concentration and hematocrit value of rats fed godulbaegi diet were similar to the control diet. The ratio of spleen weight to body weight in godulbaegi group for 8 weeks was greater than in that of control group, but they were similar both feeding groups in liver and kidney. The concentrations of the total lipid and triglyceride in serum were increased in rats fed godulbaegi diet for 4 week than in those fed control diet, but those were decreased in rats fed godulbaegi diet for 8 week than in those fed the control diet. The concentrations of the phospholipid, total cholestrol and HDL-cholestrol in serum were decreased in rats fed godulbaegi diet for 8 week than in those fed control diet. The HDL-cholestrol/total cholestrol ratio and athergenic index were similar to both diet groups. There were no differences in growth, serum total protein, albumin concentrations, aspartate aminotransferase and alanine aminotransferase activities between rats fed godulbaegi diet and those fed the control diet.

This study was designed to investigate the effect of Codonopsis lanceolata extracts on carbon tetrachloride (CCl₄)­induced hepatotoxicity in rats fed high, medium or low fat diet. The liver weight was increased not by the level of fat in diet but by administration of CCl₄. Activities of serum aspartate aminotransferase (AST) and alkaline phosphatase (ALP) were significantly increased by CCl₄, the activities of AST and alanine aminotransferase (ALT) were significantly decreased in case of CCl₄ treatment with C. lanceolata extracts. In high fat diet with CCl₄ administration, the content of total lipid in liver was significantly increased, which was significantly decreased by the administration of C. lanceolata extracts. Administration of C. lanceolata water extracts remarkably prevented the tissue injury such as lipid degeneration, infiltration of inflanunatory cells and necrosis caused by CCl₄, but those methanol extracts did not affect histopathological changes of the liver as water extract. The data suggest that intake of C. lanceolata extracts would prevent lipid accumulation and hepatotoxicity induced by high fat diet and CCl₄ abministratim, and the water extract of C. lanceolata is supposed to be more effective than those methanol extract.

Aquaculture production of Korean rockfish Sebastes schlegeli has been continuously increased from 2000s and the fish has become the second most important mariculture fish in Korea. However, there are some environmental problems in aquaculture of Korean rockfish recently. In this regards, stress responses to high water temperature was examined via oxygen consumption, blood physiological parameter and endocrinological method. Oxygen consumption of Korean rockfish had significantly increased with rising water temperature. And oxygen consumption during the light time was no different with the dark time. The levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) showed no difference until $27^{\circ}C$, but it had rapidly increased at $30^{\circ}C$. Moreover high water temperature affected to increase in plasma glucose and cortisol levels.

In order to investigate whether or not the alcohol-treated rat liver cells can be protected by Korean Citrus junos and medicinal herbs, We compared the serum biochemistry of rats administered both alcohol and the complex of Korean Citrus junos and medicinal herbs to control rats treated with alcohol alone. The activities of Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT) in the citron 3 (Citron 3, less mellowed citron which was ripened for three months)＋Phellinus linteus, Alnus japonica, Dendropanax morbifera and citron 4 (Citron 4, completely mellowed citron which was ripened fer four months)＋Phaseolus radiatus, Cordyceps militaris group were significantly low when compared with the negative control group (p<0.05). The levels of triglyceride (TG) in all experimental groups were significantly lower than the negative control group (p<0.05). The concentrations of total cholesterol in the citron 3＋Phellinus linteus, Atnus japonica, Dendropanax morbifera and citron 4＋Phaseolus radiatus, Cordyceps militaris, Phellinus linteus were lower than the negative control group (p<0.05). The activities of alcohol dehydyogenase (ADH) in all experimental groups were significantly high when compared with the normal control group (p<0.05). These results suggest that the complex of Korean Citrus junos and medecinal herbs could be an excellent candidate for protecting vat liver cell damage induced by alcohol.

This study was to elucidate the effects of Ukgan-san on the hyperthyroidism induced by sodium levothyroxine. Hyperthyroidisms were induced by continuous subcutaneous treatment of LT4, 0.3 mg/kg, once a day for 27days, and 1,500, 1,000 and 500 mg/kg of Ulkansan extracts were orally administered, once a day for 15 days from 12th LT4 treatment, and the changes on the body, thyroid gland, liver and epididymal fat pad weights, serum triiodothyronine(T3), thyroxine(T4), thyroid-stimulating hormone(TSH), asparte aminotransferase (AST) and alanine aminotransferase (ALT) concentrations, hepatic lipid peroxidation(LPO), glutathione(GSH), superoxide dismutase(SOD) and catalase(CAT) activities were investigated with throid gland, liver and epididymal fat pad histopathological changes. The effects of Ukan-san extracts were compared with that of propyl thiouracil(PTU), a standard antithyroidic drug 10 mg/kg(intraperitoneally). 1,500 and 1,000 mg/kg of Ukan-san extracts reversed all LT4-induced hyperthyroidisms and these effects indicating their potential in the regulation of hyperthyroidism. Further, the Ukan-san extract normalized LT4-induced liver oxidative stresses, and also reduced liver damages and epididymal fat pad reducements suggesting its antioxidative and relative organ protective nature. However, nor favorable effects on LT4-induced hyperthyroidisms were detected in Ulkansan 500 mg/kg treated rats as compared with LT4 control rats in the present study. These effects of Ukan-san may help improvement of hyperthyroidisms and accompanied various organ damages.
