Central venulitis in pediatric liver allografts

Alyssa M. Krasinskas, Eduardo D. Ruchelli, Elizabeth B. Rand, Jesse L. Chittams, Emma E. Furth – 30 December 2003 – Central venulitis (CV), a distinct histologic lesion described in adult liver transplants, can occur with acute portal tract rejection or in isolation (ICV). Possible etiologies include immunosuppressive drug toxicity, acute cellular rejection, viral hepatitis, ischemic injury, and recurrent disease.

Repopulation of mouse liver with human hepatocytes and in vivo infection with hepatitis B virus

Maura Dandri, Martin R. Burda, Eva Török, Joerg M. Pollok, Alicja Iwanska, Gunhild Sommer, Xavier Rogiers, Charles E. Rogler, Sanjeev Gupta, Hans Will, Heiner Greten, Joerg Petersen – 30 December 2003 – Mice containing livers repopulated with human hepatocytes would provide excellent in vivo models for studies on human liver diseases and hepatotropic viruses, for which no permissive cell lines exist.

Resistance to fulminant hepatitis and carcinogenesis conferred by overexpression of retinoblastoma protein in mouse liver

Toshiaki Ichihara, Yoshinori Komagata, Xiao‐Li Yang, Tadayoshi Uezato, Katsuhiko Enomoto, Kenji Koyama, Jun‐ichi Miyazaki, Toshihiro Sugiyama, Naoyuki Miura – 30 December 2003 – Previously, retinoblastoma (Rb) transgenic mice were produced under the control of the Rb gene promoter and showed dwarf characteristics. Here, we created transgenic mice, in which the human Rb gene was controlled by the hepatocyte nuclear factor‐1 gene promoter/enhancer and was expressed primarily in the liver. The liver of these novel transgenic mice was normally developed.

Ursodeoxycholic acid administration in patients with cholestasis of pregnancy: Effects on primary bile acids in babies and mothers

Giuseppe Mazzella, Rizzo Nicola, Azzaroli Francesco, Simoni Patrizia, Bovicelli Luciano, Miracolo Anna, Simonazzi Giuliana, Colecchia Antonio, Nigro Giovanni, Mwangemi Constance, Festi Davide, Roda Enrico – 30 December 2003 – Little is known about the effects on the fetus of ursodeoxycholic acid (UDCA) treatment for intrahepatic cholestasis of pregnancy (ICP). Twenty ICP patients were given UDCA at 1.5 to 2 g/d, to our knowledge the highest dosage yet reported.

Sinusoidal ultrastructure evaluated during the revascularization of regenerating rat liver

Kathryn E. Wack, Mark A. Ross, Vasthy Zegarra, Laura R. Sysko, Simon C. Watkins, Donna Beer Stolz – 30 December 2003 – Sinusoidal endothelial cell (SEC) porosities were compared between the periportal (zone 1) and pericentral (zone 3) regions of the rat liver during regeneration following partial hepatectomy (PHx). SEC porosities and fenestration diameters were measured in control livers, as well as at 5 minutes, 24, 48, 72, 96, 120 hours, and 14 days following PHx.

RECK gene expression in hepatocellular carcinoma: Correlation with invasion‐related clinicopathological factors and its clinical significance

Katsuyoshi Furumoto, Shigeki Arii, Akira Mori, Hiroaki Furuyama, Manuel J. Gorrin Rivas, Teizou Nakao, Naoki Isobe, Toru Murata, Chiaki Takahashi, Makoto Noda, Masayuki Imamura – 30 December 2003 – The RECK (reversion‐inducing‐cysteine‐rich protein with Kazal motifs) gene was initially isolated as a transformation suppressor gene. It encodes a membrane‐anchored glycoprotein with multiple serine protease inhibitor‐like domains. The RECK gene is expressed widely in normal organs but is undetectable in many tumor‐derived cell lines.

Outcome of hospital care of liver disease associated with hepatitis C in the United States

W. Ray Kim, John B. Gross, John J. Poterucha, G. Richard Locke, E. Rolland Dickson – 30 December 2003 – We describe mortality and resource utilization for inpatient care of hepatitis C (HCV) in comparison to alcohol‐induced liver disease (ALD) in the United States and identify factors that affect outcomes. The Healthcare Cost and Utilization Project database, a national inpatient sample was used to identify hospitalization records with diagnoses related to liver disease from HCV and ALD.
