Acute infectious mononucleosis, caused by Epstein-Barr virus(EBV), is a self limited lymphoproliferative illness that is common in adolescents and young adults. It shows many complications in multiple organ systems, but the hepatobiliary and the respiratory complication is uncommon. We report a case with thickened gallbladder wall and pneumonia as complications of acute infectious mononucleosis in a child. Also the related literature were reviewed. A 4 year old boy presented with a history of high fever, cough, and abdominal distension for 20days. Physical Examination revealed audible crackles in whole lung field and gross hepatomegaly. Chest X-ray showed pneumonia and liver function tests were abnormal. Ultrasonography and computed tomography revealed a thickened gallbladder wall and hepatosplenomegaly. The diagnosis of primary Epstein-Barr viral infection was eventually made by specific serologic tests. The patients's fever subsided 6 weeks later and pneumonia was recovered around this time. Liver function tests returned near normal 2 months later and ultrasonography of gallbladder was normal at this time.

Non-alcoholic fatty liver disease (NAFLD) is common in obesity. However, weight reduction alone does not prevent the progression of NAFLD to end-stage disease associated with the development of cirrhosis and liver disease. In a previous experiment, 50% ethanol extract of Acanthopanax senticosus stem bark (ASSB) was found to reduce body weight and insulin resistance in high fat diet-induced hyperglycemic and hyperlipidemic ICR mice. To evaluate the anti-steatosis action of ASSB, insulin-resistant ob/ob mice with fatty livers were treated with ASSB ethanol extract for an 8 week-period. ASSB ethanol extract reversed the hepatomegaly, as evident in reduction of % liver weight/body weight ratio. ASSB ethanol extract also specifically lowered circulating glucose and lipids, and enhanced insulin action in the liver. These changes culminated in inhibition of triglyceride synthesis in non-adipose tissues including liver and skeletal muscle. Gene expression studies confirmed reductions in glucose 6-phosphatase and lipogenic enzymes in the liver. These results demonstrate that ASSB ethanol extract is an effective treatment for insulin resistance and hepatic steatosis in ob/ob mice by decreasing hepatic lipid synthesis.

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.

Forty two patients with chronic constrictive pericarditis, who were admitted to the Yonsei University College of medicine over a period of 18 years from January, 1970 to August, 1988, were analyzed retrospectively. Mean age of the patient was 33.5 year ranging from 6.8 to 60 years old. Male to female ratio was 1.3 to 1. Twenty-one cases [50%] were tuberculous origin [based on either associated pulmonary tuberculosis and/or caseous necrosis in thickened pericardial specimen] and 17 cases [40.5%] were idiopathic [non specific chronic inflammatory change was considered to be idiopathic]. Dyspnea on exertion was evident in 30 cases [71.4%] and abdominal distention in 21 cases [50%]. On physical examination, hepatomegaly [83.3%], neck vein distention [54.8%], distant heart sound [47.6%] and ascites were found. Thirty-nine patients showed low voltage of QRS and/or T wave flattening or inversion on EKG. Thirty-one cases had undergone cardiac catheterization which showed data compatible with chronic constrictive pericarditis. Midsternostomy group [n=15] had shown the most remarkable CVP decline [12.20 mmHg] as compared with bilateral submammary incision group [n=25, 8.96 mmHg] and left thoracotomy group [n=2, 7.75 mmHg] but difference was not significant statistically There was four early death among 42 patients [9.5%] including 3 cases of left ventricular failure and one cardiac tamponade. Main postoperative complications were wound infection [6 cases] and arrhythmia [3 cases]. Follow-up of 24 patients [mean; 55.3 months, ranging from 2 months to 155 months] revealed good functional status.

Correlation between the blood clearance half time and findings of liver scan using the colloidal radiogold in patients of liver cirrhosis is observed through the scoring system, in which the more changes in size, shape and density in the liver scan, the more points are given (table 1). Results: 1) Within the increase in severity of hepatocellular dysfunction in liver cirrhosis, the degree and frequency of following changes in liver scan (done with colloidal radiogold) were increased in order. a) generalized hepatomegaly b) enlargement of the left lobe & reduction of the right lobe c) relatively increased radiodensity in the left lobe and 4) visualization of spleen. 2) Frequency of the normal scan in liver cirrhosis was $12{\pm}3.56%$, frequency of normal value in blood clearance half time of the radiogold was $5.0{\pm}2.34%$ and frequency of normal scan & normal blood clearance rate in liver cirrhosis was $3.6{\pm}2.06%$.

This study was concerned with assessment of dietynitrosamine (DEN) induced liver cell carcinogenesis by measurement of changes preceding the development of neoplasms. The changes of hepatic morphology in rats(Sprague-Dawley) were detected by hematoxylin-eosin stain and immunohistochemistry(PCNA). The results were as follows ; 1. Minor behavioral change, brittleness of hair and decreased amount of water and diet intake. were observed in rats 7 weeks after DEN administration. 2. Variable size of liver tumor and hepatomegaly were observed in rats treated with DEN after 10 weeks. 3. Numerous vacuoles were showed on the midzonal and or peripheral areas of hepatic lobules. The large and polymorphological hepatocytes with eosinophilic cytoplasm or densely basophilic mitotic nucleoli were showed. 4. Several proliferative small round cells were shown on vacuolated and necrotic areas in peripheral hepatic lobules or portal areas. 5. PCNA-positive cells were showed on the vacuolated portal areas and peripheral areas of hepatic lobules. Maximal positivity was 23.6% in the areas of small round cells. In conclusion, this result confirmed that the DEN was one of the potent hepatocarcinogens. In histopathological analysis, the altered foci, hyperplastic nodules, neoplastic nodules, adenomas and carcinomas were observed in liver tumors induced by administration of DEN in rats.

A 7-year-old, female snow goose (Anser caerulescens hyperboreus) with history of decreased activity for 2 month died in Daejeon Zoo Land in September 2006. At necropsy, granulomatous pneumonia and hepatomegaly with multiple cysts were observed. Small masses were found in the spleen. Microscopically, fibrinous pneumonia distributed in most of the lung lobe with pulmonary edema and congestion. Especially, granulomatous inflammation with numerous multinucleated giant cells was observed around the dilated bronchi. To confirm the diagnosis, acid-fast (Ziehl-Neelsen method) and periodic acid-Schiff (PAS) staining was performed. Acid-fast staining showed red bacterial colony indicating tuberculosis. PAS staining was also positive enough to diagnose aspergillus spp. co-infection that was an opportunistic fungi occurring in immuno-compromised animals. Based on the above results, we confirmed that the case submitted was diagnosed as avian tuberculosis.

Cryptococcosis is a rare in normal child and the majority of cases usually occur in patients with defective cell-mediated immunity. Infection is acquired by inhalation of organisms from the environment and disseminated via the blood stream to any organ of the body. We experienced a 7 year old girl who presented with fever, both cervical lymphadenopathy, hepatomegaly under the impression of lymphoma. However lymph node biopsy revealed cryptococcal budding and culture of lymph nodes yielded cryptococcus neoformans. The radiologic finding showed huge, multiple cervical lymph node enlargement spreading to mediastinum and abdomen. The immune fuction in term of T cell, B cell, serum immunoglobulin, complement and neutrophil function tests was normal. The patient was treated with amphotericin B and flucytosine for 6 weeks and responded to the treatment well. We report this case with brief review of the related literatures.
