The possible mechanisms of increased aryl sulfotransferase (AST) isozymes activities in cholestatic rat liver were studied. Hepatic AST-I, II and -III, IV activities were determined from the experimental rats with common bile duct ligation (CBDL). The Michaelis-Menten constants in these hepatic enzymes were also measured. The activities of mitochondrial AST-I, II and -III, IV, and microsomal AST-III, IV as well as their Vmax values were found to be increased significantly in CBDL plus taurocholic acid (TCA) injected group than in the control group, such as CBDL alone groups. However, their Km values in the experimental groups did not vary. The results suggest that TCA stimulates biosynthesis of the AST in the liver.

The possible mechanisms of decreased monoamine oxidase (MAO) A and B activities in cholestatic rat liver were studied. Hepatic and serum MAG activities were determined from the experimental rats with common bile duct ligation (CBDL). The Michaelis-Menten constants in these hepatic enzymes were also measured. The activities of mitochondrial MAO A and B, and mircosomal MAO B as well as their Vmax values were found to be decreased significantly in CBDL plus taurocholic acid (TCA) injected group than in the control group, such as CBDL alone groups. However, their Km values in the experimental groups did not vary. Serum MAO activity increased significantly in the CBDL plus TCA injected group than in the control group. The above results suggest that TCA represses biosynthesis of the MAO in the liver. The elevated activity of the serum MAO is believed to be caused by the increment of membrane permeability ofhepatocytes upon TCA mediated liver cell necrosis.

Cholelithiasis and choledocholithiasis are uncommon pediatric diseases, although clinicians have seen them with increasing frequency in children in recent years. Moreover, no case of Epstein-Barr virus (EBV) infection with cholelithiasis and choledocholithiasis has been previously reported in the English literature. We report a pediatric patient with EBV infection, a gall bladder stone, and a common bile duct stone, may have had GB and CBD stones prior to her EBV infection, whom we successfully treated with antibiotics and laparoscopic cholecystectomy for cholecystitis.

Serum $\alpha$-D-mannosidase isozyme activities were measured in rats with ethanol intoxication combined with extrahepatic cholestasis induced by common bile duct ligation for the manifestation of the biochemical background of drinking hazards under the hepatobiliary disease. When chronic ethanol intoxication was combine with extraheparlc cholestasis, the activities of the rat's serum cytosolic, Iysosomal and Golgi $\alpha$-D-mannosidase isozymes increased at a more significant rate than those of the cholestasis alone. However, when acute ethanol intoxication was combined with extrahepatic cholestasis, the activities of the above isozymes were seen in the cholestasis alone. The results suggested that the elevated activities of these isozymes in chronic ethanol intoxication with cholestasis rather than in cholestasis alone were indications of increased hepatic damages, which caused these isozymes to leak into the blood in great quantity. Accordingly, the resulting data supported the fact that alcoholic drinks were enzymologically harmful to the hepatobiliary disease.

Hepatic subcellular $\alpha$-D-mannosidases activities and its Km and Vmax values were determined in chronic ethanol intoxicated rats with extrahepatic cholestasis induced by common bile duct ligation to manifest the biochemical background of alcohol drinking hazard under the hepatobiliary disease. In case of extrahepatic cholestasis, chronic ethanol intoxication in animals led to the increased activities of liver Golgi and microsomal $\alpha$-D-mannosidase as well as the Vmax values of these enzymes. However, the difference of Km values on hepatic subcellular enzymes were not found between the experimental groups. Therefore, the results indicate that the liver Golgi and microsomal $\alpha$-D-mannosidase may be more induced in chronic ethanol intoxication animals in case of cholestasis. Accordingly, the resulting data supported the fact that alcoholic drinks may led to enhancement of the hepatobiliary liver damage.

Forme fruste choledochal cyst (FFCC) is one of the diverse types of choledochal cyst with little or no dilatation of the extrahepatic bile duct (EHBD). It is considered that FFCC has to do with the pancreatobiliary malunion (PBM). In children, 3 to 6 millimeters of EHBD is assumed to be normal. Even though there is no clear-cut definition, FFCC is likely to be associated with bile duct dilatation less than 10 millimeters. Almost all cases have PBMs and symptoms of the pancreatitis or cholangitis. We experienced a case of FFCC in a 4-year-old boy. His EHBD measures 10 mm diameter. He had symptoms of pancreatitis and elevated hepatic transaminases. The pancreatobiliary common channel was 28 millimeters. He underwent EHBD resection and Roux-en-Y hepaticojejunostomy and was discharged with no specific complications.

Objectives: Since we found patients with dyspepsia as their major symptom had high rate of headache, would like to find out a rational diagnosis ground by using EAV correlation between headache and gastrointestinal disorder Methods: We did survey and EAV inspection on 128 patients came by gastrointestinal disorder who quoted 4 and 5 degree for their headache symptoms) Results & Conclusion The results of this study were as follows: 1. From dyspepsia, we saw higher rate by order of epigastric discomfort, bloating, stomach trouble, bleching, etc. 2. By EAV analysis, found functional deterioration by order of stomach, nerval degeneration vessel, gall bladder/bile duct, liver. 3. By EAV analysis, functional deterioration of stomach, gall bladder/bile duct, liver represent dyspepsia and nerval degeneration vessel represent headache. We found the correlation between dyspepsia and headache by observation at a time.

Ascaris lumbricoides causes one of the most common soil-transmitted helminthiases globally. The worms mostly infect the human small intestine and elicit negligible or nonspecific symptoms, but there are reports of extraintestinal ectopic ascariasis. We describe a rare case of biliary ascariasis mistaken for biliary stent in a 72-year-old female patient with a history of liver resection. She visited our outpatient clinic complaining of right upper quadrant pain and fever for the past week. She had previously undergone left lateral sectionectomy for recurrent biliary and intrahepatic duct stones 2 years ago. Besides mildly elevated gamma-glutamyl transferase levels, her liver function tests were normal. Magnetic resonance cholangiopancreatography revealed a linear filling defect closely resembling an internal stent from the common bile duct to the right intrahepatic bile duct. A live female A. lumbricoides adult worm was removed by endoscopic retrograde cholangiopancreatography (ERCP). Despite a significant decrease of the ascariasis prevalence in Korea, cases of biliary ascariasis are still occasionally reported. In this study, a additional case of biliary ascariasis, which was radiologically misdiagnosed as the biliary stent, was described in a hepatic resection patient by the worm recovery with ERCP in Korea.

Obstruction of the extrahepatic bile ducts is the most common cause of conjugated hyperbilirubinemia in early infancy. More than 90% of such obstructive lesions are accounted for by extrahepatic biliary atresia. A rare lesion is obstruction of the common duct by impacted, thickened secretions and bile. Bile plug syndrome is defined as extrahepatic obstruction of the bile ducts by bile sludge in term infants without anatomic abnormalities, congenital chemical defects of bile, or hepatocellular lesions. Obstruction of extrahepatic ducts by plugs of biliary material apperas to be due to the inspissation and precipitation of bile and mucus within the lumen of the ducts. Cholestasis and precipitation of bile develop in association with abnormal composition of bile in cystic fibrosis, hepatocellular damage, prolonged erythroblastic jaundice, altered biliary dynamics with total parenteral nutrition, gut dysfunction, diuretic therapy, exchange transfusions and perinatal hemolysis. In those cases, the term inspissated bile syndrome is used. The clinical and laboratory findings in bile plug syndrome are identical to those observed in biliary atresia and choledochal cyst. The diagnosis can be suspected based on the findings of clinical and laboratory examinations together with hepatobiliary imaging, ultrasonography, radionuclide scan and liver biopsy. We experienced a case of spontaneous resolution of bile plug syndrome in a 4-year-old girl. We report this case with brief review related literatures.
