Thirteen dogs were diagnosed as congenital extrahepatic single PSS by intraoperative mesenteric portovenography or computed tomographic examination, repair surgery was performed by using an ameroid constrictor. Hepatic size was measured from the right lateral view using liver length/T11 length ratio. This measurement was performed on follow-up check of PSS ligation patients. Hepatic size parameter of pre-operative PSS patients is $4.13{\pm}0.13$ (range, 3.11-4.83). After surgery, hepatic size parameter of post-operative PSS patients is $4.79{\pm}0.19$ (range, 3.78- 5.93). Although follow-up periods varied 2 and 26 weeks, all patients showed increased liver size compared to that on pre-operative radiographs (P < 0.01). The increase rate was 1.01-1.46 times than those of preoperative radiographs. But in 5 patients, post hepatic liver size was small compared to the others, which showed low increase rate of body weight, total protein, albumin, and glucose level. It was thought that small value of hepatic size parameter was due to delay of hepatic regeneration. In conclusion, radiographic hepatic size parameter of pre- and post-operative patients is considered an effective evaluation for restoring after PSS surgery.

Objective: To document the imaging findings of hepatic cavernous hemangioma detected in cirrhotic liver. Materials and Methods: The imaging findings of 14 hepatic cavernous hemangiomas in ten patients with liver cirrhosis were retrospectively analyzed. A diagnosis of hepatic cavernous hemangioma was based on the findings of two or more of the following imaging studies: MR, including contrast-enhanced dynamic imaging (n = 10), dynamic CT (n = 4), hepatic arteriography (n = 9), and US (n = 10). Results: The mean size of the 14 hepatic hemangiomas was 0.9 (range, 0.5-1.5) cm in the longest dimension. In 11 of these (79%), contrast-enhanced dynamic CT and MR imaging showed rapid contrast enhancement of the entire lesion during the early phase, and hepatic arteriography revealed globular enhancement and rapid filling-in. On contrast-enhanced MR images, three lesions (21%) showed partial enhancement until the 5-min delayed phases. US indicated that while three slowly enhancing lesions were homogeneously hyperechoic, 9 (82%) of 11 showing rapid enhancement were not delineated. Conclusion: The majority of hepatic cavernous hemangiomas detected in cirrhotic liver are small in size, and in many, hepatic arteriography and/or contrast-enhanced dynamic CT and MR imaging demonstrates rapid enhancement. US, however, fails to distinguish a lesion of this kind from its cirrhotic background.

A 6 and a half year-old girl developed recurrent cholangitis following hepatic portoenterostomy for biliary atresia. Computed tomogram showed an ovoid cyst ($4.5{\times}4.0$ cm in size) in the left hepatic lobe and another tubular dilatation ($2.0{\times}0.8$ cm in size) in the right hepatic lobe. Percutaneous transhepatic cholangiodrainage(PTCD) and cystogram showed an ovoid cyst in the left hepatic lobe (Tsuchida type A), measuring $6.6{\times}5.0$ cm in size. Following drainage and administration of parenteral antibiotics she became afebrile and anicteric. However she continued to drain 45-150 cc of bile per day via the tube over the next 2 weeks. The patient successfully underwent intrahepatic cystojejunostomy with intraoperative ultrasonographic guidance. This case illustrates relapsing cholangitis caused by Tsuchida type A intrahepatic cyst, successfully managed with PTCD followed by an internal drainage procedure.

This histological study was performed to investigate the effects of .Paljeungsan-gagambang on the epididymal fat cell size, number and the fat drop area of hepatic lobule of rats fed High Fat Diet. Paljeungsan-gagambang was orally administered to the rats of sample group 26mg per 200g of rat's weight everyday for 4 weeks, and the control group were just fed with equal amount of saline solution. Then they are the epididymal fat cell size, epididymal fat cell numberand fat drop area of hepatic lobule that were measured. The results were summarized as follows; 1. The size of the epididymal fat cell was decreased significantly as compared with the control group. 2. The number of the epididymal fat cells was decreased significantly as compared with the control group in distribution chart classified by cell size 3. The Area(%) of the Fat drops in the hepatic lobule was decreased significantly as compared with the control group. According to the above results, it is considered that Paljeungsan-gagambang have effects on the decrease of the epididymal fat cell size, number and fat drop area of hepatic lobule of rats fed high fat diet; Thus, the adminisrtation of Paljeungsan-gagambang is considered to have an improving effect on obesities and liver diseases caused by high fat diet.

It was demonstrated that Gangjihwan (DF), which is the herbal composition composed of Ephedra intermedia, Lithospermum erythrorhizon, and Rheum palmatum, inhibits obesity and hepatic steatosis in high fat diet (HFD)-fed obese mice. The aim of this study was to determine the effects of DF on visceral obesity, hepatic inflammation and fibrosis and the mechanism of actions involved in this process using in vivo and in vitro approaches. DF was extracted with water (DF-FW), 30% grain alcohol (DF-GA30), and 70% grain alcohol (DF-GA70). Administration of DF to HFD-fed control mice decreased visceral tissue mass and visceral adipocyte size without adverse effects. Visceral fat mass was decreased by DF-GA30 and DF-GA70, and visceral adipocyte size by all three DF extracts compared with obese control mice. Histological analysis revealed that three kinds of DF extracts reduced toluidine blue-stained mast cells and collagen accumulation in the liver, the extents of which were most eminent in DF-GA70-treated mice. DF-GA70 decreased the mRNA levels of the inflammation ($TNF{\alpha}$ and VCAM-1), fibrosis (${\alpha}-SMA$), and apoptosis (caspase 3) genes, but increasing the anti-apoptosis gene (Bcl-2) mRNA levels in the liver of obese control mice. Consistent with the in vivo data, GA-70 also altered the expression of inflammation genes ($TNF{\alpha}$ and MCP-1) in HepG2 cells. These results indicate that DF not only inhibits visceral obesity, but also ameliorates visceral obesity-induced hepatic inflammation and fibrosis and that this process may be mediated by regulating the hepatic expression of inflammatory and fibrogenic genes.

After Triton WR-1339 (TX; 600mg/kg) intraperitoneal injection, hepatic tissues of ICR mice were intragastric injected with Hyulboochucketang extract(HCE; 3.3ml/kg/day) were observed to investigate the suppressive effect of lipid accumulation that evoke by the antihyperlipidemic effect of HCE. These hepatic tissues were fixed in fromol-calcium solution and were cryocut. These tissues stained by H&E for general morphology, sudan black B for lipid and perchloric acid-naphthoquinone(PAN) method for cholesterol. After TX treatment, the increase of hepatocyte having meshlike cytoplasm(HHMC) were shown in all hepatic lobules and the hepatic plates were disappeared in the aggregative region of HHMC. The number of blue black colored lipid drop and dark green colored asterisk shaped cholesterol particle in hepatic cytoplasm were increased and the size of lipid drop and cholesterol particle were enlarged. But, in HCE-treated mice, the HHCM were disappeared and hapatic plate were rearranged. The number of lipid drop and cholesterol particle were decreased than TX-treated mice and the size of lipid drop and cholesterol particle were diminished. As results indicated that the HCE work on the suppression of lipid accumulation in hepatic tissue of hyperlipidemic mice caused by disturbance of lipid metabolism.

The purpose of this study was to evaluate the pathologic results of hepatic parenchyma parameters such as liver parenchyma, liver surface, liver margin and liver, portal vein, spleen size, And to evaluate the usefulness of fibrosis progression and hepatic ultrasonography. The sensitivity, specificity, positive predictive value, and prognostic value according to the stage of fibrosis and grade of inflammation were divided into two groups according to the morphologic variable "A" through ultrasound and "B" We evaluated the predictive value and predicted the variables to evaluate fibrosis in clinical diagnosis and treatment of patients with chronic liver disease. The sensitivity and specificity of hepatic fibrosis in hepatic morphologic variables and other size variables were highest in liver surface and edge. The morphologic parameters used in the evaluation of fibrosis were clinically relevant in distinguishing the fibrosis stage from the results of liver biopsy.

This study was designed to investigate the effect of dietary level of $\beta$-carotene on level of antioxidant nutrients of rat tissues. Male Sprague Dawley rats at the age of 30days were fed on diets containing different levels of $\beta$-carotene(0, 10, 120, 1200, 12000mg per kg diet). Body weight gain of rats fed with 12000mg $\beta$-carotene diet was significantly decreased, but liver and heart weights were not significantly different among groups, The content of total glutathione tended to decrease significantly in 12000mg $\beta$-carotene diet group when compared to $\beta$-carotene restriction group(BC O). However, total vitamin C content of liver showed the tendency to increase by $\beta$ -carotene supply up to 1200mg. But this tendency was not found in plasma, The content of zinc in liver and plasma was significantly decreased by $\beta$-carotene restriction. Alkaline phosphatase activity was significantly higher in 12000mg diet group. In case of $\beta$-carotene restriction group, fibroblasts were proliferated in portal endothelium, and the vacuolar size was enlarged more than the nuclear, In 12000mg diet group, hepatic vacuoles were extended, but their size was regular and the lysis of hepatocytes was observed. Also, fibroblasts were proliferated in portal endothelium and the regular vacuolar size was extended.
