  • Hepatic toxocariasis is a type of visceral larva migrans caused by the migration of second-stage larvae of certain nematodes such as Toxocara canis to the liver. Histologically, the condition is characterized by granulomatous lesions containing eosinophils and inflammatory cells. We report a case of hepatic toxocariasis with atypical clinical and radiologic findings presenting as distinct, solitary hepatic nodule detected in a middle-aged woman.

  • It has been reported that sulfur-containing intermediates or products in the transsulfuration pathway including S-adenosylmethionine, 5'-methylthioadenosine, glutathione and taurine can prevent liver injury mediated by inflammation response induced by lipopolysaccharide (LPS) treatment. The present study examines the modulation of hepatic metabolism of sulfur amino acid in a model of acute sepsis induced by LPS treatment (5 mg/kg, iv). Serum TNF-alpha and hepatotoxic parameters were significantly increased in rats treated with LPS, indicating that LPS results in sepsis at the doses used in this study. LPS also induced oxidative stress determined by increases in malondialdehyde levels and decreases in total oxy-radical scavenging capacities. Hepatic methionine and glutathione concentrations were decreased, but S-adenosylho-mocysteine, cystathionine, cysteine, hypotaurine and taurine concentrations were increased. Hepatic protein expression of methionine adenosyltransferase, cystathionine beta-synthase and cysteine dioxygenase were induced, but gamma-glutamylcysteine ligase catalytic subunit levels were decreased. The results show that sepsis activates transsulfuration pathway from methionine to cysteine, suggesting an increased requirement for methionine during sepsis.

  • The effect of dietary capsaicin (8-methyl-N-vanillyl-6-nonenamide, CAP) on drug-metabolizing enzyme activities was investigated in mice. Male ICR mice were divided into 4 groups and fed diets containing 0, 5, 20, 100 ppm CAP for 4 seeks. Hepatic drug-metabolizing enzyme activities and serum alanine aminotransferase and aspartate transaminease activities were measured. There was no difference in hepatic alanine aminotransferse and aspartate transaminase activities among the groups. Hepatic microsomal cytochrome P450 in CAP fed groups, but p-nitrophenol hydroxylase and the cytosolic acitivity of glutathione S-transferase activities were decreased in the dietary CAP supplemetned groups compared to the control. These results suggest that the dietary CAP at a low dose differentially modulates drug-metabolizing enzyme acitvities without causing hepatic toxicity.

  • We herein report a very rare case of adult right-sided Bochdalek hernia accompanied with hepatic hypoplasia and inguinal hernia. A 29-year-old man was admitted with right-sided pneumothorax. A computed tomography was performed and revealed large right sided Bochdalek hernia with hepatic hypoplasia. Under thoracolaparotomy, the defect was closed with Gore-Tex soft tissue patch. After the operation, left-sided inguinal hernia was found. However, it turned out that it had been present during infancy and spontaneously resolved during adolescence. This is the first report of right-sided Bochdalek hernia with hepatic hypoplasia and inguinal hernia in an adult.

  • Baicalein (5,6,7-trihydroxyflavone), a flavonoid originated from the root of Chinese medicinal herb Scutellaria baicalensis, has been shown to exert anti-inflammatory and antioxidant effects and hepatic stellate cells play an important role in the pathogenesis or hepatic fibrosis. In this study, we investigated apoptosis stimulation by baicalein in activated rat hepatic stellate cells (T-HSC/C1-6). Transformed rat hepatic stellate cells (T-HSC/C1-6) were treated with baicalein(100uM, 70uM, 40uM). Apoptosis was determined by detection of DNA fragmentation in gel electrophoresis, morphological alternations by flow cytometry and quantification of phosphatidylserine externalization by Annexin V labeling.

  • The increased deposition of extracellular matrix by hepatic stellate cells following liver injury in a process known as activation is considered a key mechanism for increased collagen content of liver during the development of liver fibrosis. In this study, we investigated the protective effects of an aqueous extract from the roots of Platycodon grandiflorum A. DC (Campanulaceae), Changkil (CK), on hepatic fibrosis in hepatic stellate cells. We report that CK reduces the accumulation of collagen in acetaldehyde-induced hepatic stellate cells. (omitted)

  • Hepatic stellate cells (HSC) and the derived myofibroblasts are known to play a central role in liver fibrogenesis. Rhus verniciflua Strokes (RVS) has traditionally been used in Korea herbal medicine for a stomachic tonic. In this study, we observed the effect of RVS acetone extract (Ra) and its five major components on the proliferation, the collagen synthesis, and hepatic fibrosis related proteins mRNA levels in HSC-T6 cells which is a fully activated rat hepatic stellate cell line. Ra inhibited the proliferation and decreased the content of collagen in the HSC-T6 cells. (omitted)

  • The arterial support of the liver is most commonly from the celiac trunk via the proper hepatic artery (PHA). The PHA divides into left and right branches: the right hepatic artery (RHA) supplies the right and caudate lobes while the left hepatic artery (LHA) supplies the left and quadrate lobes. Aberrant hepatic arteries are relatively common, and the most frequent contributors are the superior mesenteric artery and left gastric artery. Herein we present findings from postmortem dissection of an abdominal cavity that revealed a rare combination of reported variations. Specifically, this subject had three extrahepatic arteries - a replaced LHA (rLHA), a PHA, and a replaced RHA (rRHA). The rLHA originated from the left gastric and the rRHA originated from the superior mesenteric artery. Knowledge of these variations is important for surgical and radiological procedures to avoid complications during treatment and improve patient outcomes.

  • Nonalcoholic fatty liver disease, characterized by excessive accumulation of fat in the liver, is the most common chronic liver disease worldwide. The current standard for the detection of hepatic steatosis is liver biopsy; however, it is limited by invasiveness and sampling errors. Accordingly, MR spectroscopy and proton density fat fraction obtained with MRI have been accepted as non-invasive modalities for quantifying hepatic steatosis. Recently, various quantitative ultrasonography techniques have been developed and validated for the quantification of hepatic steatosis. These techniques measure various acoustic parameters, including attenuation coefficient, backscatter coefficient and speckle statistics, speed of sound, and shear wave elastography metrics. In this article, we introduce several representative quantitative ultrasonography techniques and their diagnostic value for the detection of hepatic steatosis.

  • Calvert et al. formulated the hypothesis that carbon tetrachloride ($CCl_4$) acted on the central nervous system to produce and intensify sympathetic discharge which resulted in anoxic necrosis of the liver. Recknagel suggested that the essential feature of $CCl_4$ hepatotoxicity depended on the cleavage of it to $CCl_3$(free radical) and the peroxidative decomposition of cytoplasmic membrane structural lipids. And there are many reports which show the increase of adrenergic activity in hyperthyroidism. In this paper, the influence of thyroxine on the hepatotexicity of carbon tetrachloride was investigated in mice. The results obtained were summarized as follows; 1) Hepatic total lipid and lipid peroxide contents were slightly decreased by L-sodium thyroxine injection(4mg/kg/day for 4days or 6days), but hepatic glycogen content was significantly decreased. 2) Hepatic total lipid and lipid peroxide contents and serum lactic dehydrogenase activity were significantly increased by $CCl_4$ (4 ml/kg single dose or triple dose: 4ml/kg/day for 3days), but hepatic glycogen content was significantly decreased. 3) The increase of hepatic total lipid and lipid peroxide contents and serum lactic dehydrogenase activity induced by $CCl_4$ were significantly inhitited by the pretreatment of thyroxine. 4) The decrease of hepatic glycogen induced by $CCl_4$ was not affected by the pretreatment of thyroxine.
