Inhibition of macrophages with gadolinium chloride alters intercellular adhesion molecule‐1 expression in the liver during acute endotoxemia in rats

Nosheen Ahmad, Carol R. Gardner, Edward J. Yurkow, Debra L. Laskin – 30 December 2003 – Cell adhesion molecules are important for localized accumulation of phagocytes at sites of tissue damage. In the present studies, we analyzed the effects of blocking hepatic macrophages on expression of β2 integrins and intercellular adhesion molecule‐1 (ICAM‐1) adhesion molecules on liver cells during acute endotoxemia. Flow cytometric analysis revealed distinct subpopulations of macrophages from control animals that varied on the basis of their size and density.

Acute carbon tetrachloride feeding selectively damages large, but not small, cholangiocytes from normal rat liver

Gene D. LeSage, Antonio Benedetti, Shannon Glaser, Luca Marucci, Ziga Tretjak, Alessandra Caligiuri, Rebecca Rodgers, Jo Lynne Phinizy, Leonardo Baiocchi, Heather Francis, John Lasater, Laura Ugili, Gianfranco Alpini – 30 December 2003 – The aim of this study was to develop a model of selective duct damage restricted to hormone‐responsive segments corresponding to the ducts damaged in primary biliary cirrhosis (PBC). Carbon tetrachloride (CCl4) was fed by gavage to rats, and 2, 7, 14, and 28 days later, small and large cholangiocytes were isolated.

The economic impact of esophageal variceal hemorrhage: Cost‐effectiveness implications of endoscopic therapy

Ian M. Gralnek, Dennis M. Jensen, Thomas O. Kovacs, Rome Jutabha, Gustavo A. Machicado, Jeffrey Gornbein, Joy King, Susie Cheng, Mary Ellen Jensen – 30 December 2003 – Esophageal variceal hemorrhage (EVH) is a serious and expensive sequela of chronic liver disease, leading to increased utilization of resources. Today, endoscopic sclerotherapy (ES) and endoscopic ligation (EL) are the accepted, community standards of endoscopic treatment of patients with EVH. However, there are no published studies comparing the economic costs of treating EVH using these interventions.

Effects of sho‐saiko‐to, a japanese herbal medicine, on hepatic fibrosis in rats

Ichiro Shimizu, Yue‐Rong Ma, Yoko Mizobuchi, Fei Liu, Tetsuo Miura, Yoichiro Nakai, Mitugi Yasuda, Masako Shiba, Takahiro Horie, Sakae Amagaya, Norifumi Kawada, Hitoshi Hori, Susumu Ito – 30 December 2003 – It has been shown that lipid peroxidation is associated with hepatic fibrosis and stellate cell activation. Sho‐saiko‐to (TJ‐9) is an herbal medicine, which is commonly used to treat chronic hepatitis in Japan, although the mechanism by which TJ‐9 protects against hepatic fibrosis is not known.

Perioperative change in albumin messenger RNA levels in patients with hepatocellular carcinoma

Tomonobu Gion, Akinobu Taketomi, Mitsuo Shimada, Ken Shirabe, Hirofumi Hasegawa, Kenji Takenaka, Keizo Sugimachi – 30 December 2003 – A quantitative assay of albumin messenger RNA (mRNA) in blood samples was designed using the competitive reverse‐transcription polymerase chain reaction, and the significance of measuring albumin mRNA levels in the blood of patients with hepatocellular carcinoma (HCC) in hepatic resection was evaluated.

Xanthine oxidase inhibition attenuates kupffer cell production of neutrophil chemoattractant following ischemia‐reperfusion in rat liver

Fujio Matsumura, Yasuo Yamaguchi, Mataro Goto, Osamu Ichiguchi, Eiji Akizuki, Teishi Matsuda, Kazutoshi Okabe, Jian Liang, Hajime Ohshiro, Takeshi Iwamoto, Shinwa Yamada, Katsutaka Mori, Michio Ogawa – 30 December 2003 – We investigated the effects of the xanthine oxidase inhibitor, BOF‐4272, on the production of cytokine‐induced neutrophil chemoattractant (CINC) following reperfusion injury in rat liver. Ischemia was induced for 30 minutes by portal vein occlusion.

Identification of glutathione S‐transferase isozymes and γ‐glutamylcysteine synthetase as negative acute‐phase proteins in rat liver

Timo M. Buetler – 30 December 2003 – Because acute infection and inflammation affect drug metabolism and drug‐metabolizing enzymes, the effect of the acute‐phase response on the expression of glutathione S‐transferase (GST) isoenzymes, glutathione synthesis, and several antioxidant enzymes was investigated. Hepatic expression of GST isozymes, positive and negative acute‐phase reactants, and antioxidant enzymes were determined by Northern blotting and hybridization with gene‐specific oligonucleotide probes after lipopolysaccharide treatment of rats.

KAI1, A new metastasis suppressor gene, is reduced in metastatic hepatocellular carcinoma

Xiao‐Zhong Guo, Helmut Friess, Fabio F. Di Mola, Jean‐Marc Heinicke, Mohamed Abou‐Shady, Hans U. Graber, Hans U. Baer, Arthur Zimmermann, Murray Korc, Markus W. Büchler – 30 December 2003 – Down‐regulation of KAI1 expression has been shown to be associated with formation of metastases or disease progression in prostate and pancreatic cancer.
