  • Objective : This study was performed to investigate the anti-fibrogenic effect and changes of inflammation-related genes by YBR I and YBR II (YBR I: Arteisiae Capillaris Herba, Atractylodis Rhizoma Alba, Hoelen/ YBR II: YBR I +Sanguisorbae Radix, Biotae Cacumen, Cirsii Japonici Herba) on HSC(hepatic stellate cells)-T6 and TAA-induced rat liver tissue. Materials and Methods : HSC-T6 were treated with various concentrations of distilled-water extract YBR I and YBR II extract for 24, 48 and 72 hours. After the treatment, cell viability, proliferation, procollagen levels and IL-6 levels were measured by using MTT Assay, BrdU Assay, Procollagen Type 1 C-peptide EIA kit, and Murine IL-6 ELISA Development kit. Rat liver fibrosis was induced by intraperitoneal TAA injection of 150mg/kg 3 times a week for 6 weeks. After the treatment, body weight, liver & spleen weights, liver function test, complete blood cell count and change of portal pressure were studied. In addition, gene expressions of ASMA, IL-6, MMP-2, TIMP-1 and TIMP-2, all of which are known to be associated with liver fibrosis, were analyzed by using Real-Time PCR. After YBR I and YBR IItreatment, percentages of collagen in TAA-induced rat liver tissue were measured. Results : The viability and proliferation of the HSC-T6 decreased as the concentration increased. The production of procollagen decreased as the concentration increased. The production of IL-6 was little influenced by YBR I and YBR II. There was no difference in rat body weight between the TAA-only group and the YBR groups. Compared with rat liver weight of TAA-only group, that of the YBR groups increased. In the YBR I group, the serum level of AST elevated by TAA injection significantly decreased and in the YBR I and II group, the serum level of ALP and ALT elevated by TAA injection decreased. In the YBR I group, white blood cell count elevated by TAA injection decreased but platelets increased. In the YBR I group, the portal pressure elevated by TAA injection significantly decreased. Decreases in the gene expression of ASMA and MMP-2 were observed in the YBR I group. The gene expression of IL-6 was little influenced by YBR I and YBR II -treated groups. In the histological finding, TAA injections caused severe fibrosis, but YBR I and YBR II treatment significantly reduced the amounts of hepatic collagens. Conclusions : These results suggest that YBR I and II have inhibitory effects on the hepatic fibrogenesis.

  • Angiomyolipoma(AML) of the liver is a rare benign tumor; about 50 cases, almost solitary, have been reported. We present here a extremely rare case of multiple AML in the liver diagnosed by fine needle aspiration cytology(FNAC). Two large masses were found in a 51 year-old woman complaining of abdominal discomfort by computed tomography and several smaller masses are scattered in the liver. FNAC was performed, showing bundles of spindle shaped smooth muscle cells intermingled with mature fat cells. FNAC may be a valuable method for definitive diagnosis of hepatic AML. The diagnosis was further confirmed by histologic examination with immunohistochemical studies.

  • Extrathoracic metastases of thymomas are extremely rare, occurring in less than 2% of cases. We present a case of metastatic thymoma in the liver diagnosed by aspiration biopsy. A fine-needle aspirate from a hepatic mass of a 65-year old man who had a history of malignant thymoma locally invading pericardium was examined. Nests of epithelial cells with few scattered lymphocytes were present. The nuclei of the epithelial cells were round to oval and appeared relatively uniform and regular, with fine chromatin pattern. They had one or two, small but lather conspicuous nucleoli. Unlike previous reports on the findings of the aspiration cytology of thymomas, the characteristic biphasic pattern was not present in this case.

  • Effects of Ssang Wha Tang (SWT), a blended Chinese traditional medicine, on the pharmacokinetics of sulfobromophthalein (BSP) were studied in the rats. BSP was administered via portal vein to the control and the SWT-treated rats. The in vitro distribution of BSP to blood cells and the hemato-physiological conditions, liver weight, GOT. GPT activity were also examined. The systemic clearance $(CL_s)$ of BSP was increased with the administration of SWT, but no significant differences were observed in the liver weight and in vitro distribution of BSP to blood cells. These results suggest that the intrinsic clearance of free BSP of the liver is increased with the administration of SWT in the rats.

  • Sepsis remains the leading cause of morbidity and mortality following trauma. Although hepatocellular dysfunction occurs during trauma and sepsis. the mechanism responsible for this remains unclear. We investigated the role of Kupffer cells in the alterations in microsomal drug metabolizing function during trauma and sepsis. Rats were subjected to trauma by femur fracture (FFx). After 72h, polymicrobial sepsis was induced by cecal ligation and puncture(CLP). (omitted)

  • The preventive effect of Sosiho-Tang extract administered concurrently with methionine on hepatotoxicity induced by carbon tetrachoride (20% $CCl_4$ in olive oil, 5 ml/kg) in rats was studied. S-GOT values were decreased significantly by the concurrent administration of Sosiho-Tang extract 100 mg/kg with methionine 100 mg/kg and also Sosiho-Tang 200 mg/kg with methionine 100 mg/kg. S-GPT values were decreased remarkably by the concurrent administration of Sosiho-Tang extract 200 mg/kg with methionine 100 mg/kg. In histological observations, the pattern of the contrast group indicated the marked necrosis of the parenchymatous cells around the centrilobular area and the fatty changes of the hepatic cells around the midzonal area, but the concurrent administration of Sosiho-Tang extract 200 mg/kg and methionine 100 mg/kg revealed better improvements than their respective single administration in all pathological aspects.

  • In order to find the new hepatoprotective agents preliminary screening of twelve prescriptions which have been used for the treatment of hepatic disease in Oriental traditional medicine has been carried out. Both DPPH free radical scavenging and hepatoprotective effect on tacrine-induced cytotoxicity in Hep G2 cells are performed. Osumokkya-tang which is one of the prescription belongs to interior-warming properties showed the DPPH free radical scavenging effect as well as hepatoprotective activity significantly. It is also suggested that its hepatoprotective effect is derived from Chaenomelis Fructus.

  • Since April, 1957, 200 White Leghorn and 100 Newhampshire had been brought to the poultry farm of our college from Songwhan National Breeding Station. The looses due to avian tuberculosis were 67 chickens by June, 1959. Thirteen of them were examined histopathologically. Grayish white tuberculous nodules varying in size were recognized in the liver, spleen, bone marrow, and intestine of all affected birds. The heart rind testis were involved in each case, and pulmonary tuberculosis which, unlike in mammals, was kown to be rarely encountered in birds was observed in two cases. One case showed amyloid like degeneration in hepatic cell cords of the liver, glomerular tufts and collecting ducts of the kidney. Lesions in the spleen presented typical Sago spleen. Sections from the liver, spleen, intestine, and lungs were stained by Ziel-Neelsen stain. Acid Fast stained bacilli were found embeded in the cytoplasm of epithlioid cells and foreign-body giant cells.

  • $^{99m}Tc-Sulfur$ Colloid is concentrated in Kupffer cells of the liver, whereas the new biliary agents such as $^{99m}Tc-HIDA$ are processed by hepatic parenchymal cells. The distant metastatic lesiors in skull and lung of the primary hepatocellular carcinoma in 38-year old Korean male were detected with $^{99m}Tc-HIDA$ scintigraphy. The chest PA, skull bone X-ray and radionuclide scintigraphic studies are illustrated. This observation suggests that $^{99m}Tc-HIDA$ scintigraphy is useful for detection of distant metastases of primary hepatocellular carcinoma.

  • The liver lies at the intersection of multiple metabolic pathways and consequently plays a central role in lipid metabolism. Pathological disturbances in hepatic lipid metabolism are characteristic of chronic metabolic diseases, such as obesity-mediated insulin resistance, which can result in nonalcoholic fatty liver disease (NAFLD). Tissue damage induced in NAFLD activates and recruits liver-resident and non-resident immune cells, resulting in nonalcoholic steatohepatitis (NASH). Importantly, NASH is associated with an increased risk of significant clinical sequelae such as cirrhosis, cardiovascular diseases, and malignancies. In this review, we describe the immunopathogenesis of NASH by defining the known functions of immune cells in the progression and resolution of disease.
