BACKGROUND Chronic colitis-harboring TCRalpha(- / - ) x AIM(- / - ) mice showed PBC-like bile duct damage in the liver. Bacterial infection is one of the candidates for the pathogenesis of PBC. We demonstrated that the bacterial cell wall component lipotheicoic acid (LTA) was detected at sites of inflammation around damaged bile ducts in PBC patients. The aim of this study was to investigate th...

BACKGROUND Peroxisome proliferators-activated receptor alpha (PPARalpha) activation modulates cholesterol metabolism and suppresses bile acid synthesis. This study aims to evaluate the effect of short-term administration of fenofibrate, a PPARalpha agonist, on proinflammatory cytokines, apoptosis, and hepatocellular damage in cholestasis. METHODS Forty male Wistar rats were randomly divided i...

In situations like peritonitis due to bile duct injuries drains insertion give an opportunity for healing. However in presented case the leakage from spontaneously stopped. Only constipation leads icterus. A spontaneous choledoco enteric fistula explains these conditions, discovered later. It could be result of inflammation causing adhesion.

The etiology and pathogenesis of bile duct obstruction in children with biliary atresia are largely unknown. We have previously reported that, despite phenotypic heterogeneity, genomic signatures of livers from patients display a proinflammatory phenotype. Here, we address the hypothesis that production of IFN-gamma is a key pathogenic mechanism of disease using a mouse model of rotavirus-induc...

Intestinal failure (IF)-associated liver disease (IFALD), as a major complication, contributes to significant morbidity in pediatric IF patients. However, the pathogenesis of IFALD is still uncertain. We here investigate the roles of bile acid (BA) dysmetabolism in the unclear pathogenesis of IFALD. It found that the histological evidence of pediatric IF patients exhibited liver injury, which w...

Primary neuroendocrine carcinoma of the gallbladder is extremely rare because normal gallbladder mucosa does not contain neuroendocrine cells. Neuroendocrine cells can be detected at sites of intestinal metaplasia induced by chronic inflammation, which may be the initial step in the development of neuroendocrine tumor of the gallbladder. Anomalous union of the pancreaticobiliary duct (AUPBD) is...

BACKGROUND AND AIMS Intestinal metaplasia (IM) at the cardia is likely to be a precursor of cardia cancer. Previous work has shown that it is associated with chronic inflammation attributable to either gastro-oesophageal reflux disease (GORD) or Helicobacter pylori infection. An alternative aetiological factor is bile reflux. Duodenogastric reflux brings about histological changes in the gastri...

BACKGROUND Inflammation is proposed to impair reverse cholesterol transport (RCT), a major atheroprotective function of high-density lipoprotein (HDL). The present study presents the first integrated functional evidence that inflammation retards numerous components of RCT. METHODS AND RESULTS We used subacute endotoxemia in the rodent macrophage-to-feces RCT model to assess the effects of inf...

Farnesoid X receptor (FXR, NR1H4) is a member of the nuclear hormone receptor superfamily, which plays an essential role in regulating bile acid, lipid, and glucose homeostasis. Both male and female FXR(-/-) mice spontaneously developed liver tumors; however, no other tumors were developed after 15 months of age. In contrast, no liver tumors were observed in wild-type mice of the same age. Hist...

Obstructive jaundice caused by tuberculous lymphadenitis is a rare manifestation of tuberculosis (TB), with 15 cases having been reported in Korea. We experienced a case of obstructive jaundice caused by pericholedochal tuberculous lymphadenitis in a 30-year-old man. The patient's initial serum total bilirubin level was 21.1 mg/dL. Abdominal computed tomography revealed narrowing of the bile du...
