Sebastiano Siringo, Luigi Bolondi, Stefano Gaiani, Soccorsa Sofia, Gianni Zironi, Alessandra Rigamonti, Giulio Di Febo, Mario Miglioli, Giancarlo Cavalli, Luigi Barbara – 1 July 1994 – We followed 87 cirrhotic patients with esophageal varices and without previous hemorrhage for a mean period of 24 mo to prospectively evaluate the occurrence of variceal bleeding within (early) or after (late) 6 mo from entry and the contribution of portal Doppler ultrasound parameters to the prediction of early and late hemorrhage.

Yasuharu Ikeda, Takashi Matsumata, Hiroshi Hayashi, Akinobu Taketomi, Kazuharu Yamamoto, Keizo Sugimachi – 1 July 1994 – In an attempt to ascertain the possible beneficial or adverse effects of ethanol injection into a hepatic malignant tumor, we carried out a series of experiments using the RBT‐1 carcinoma.

Roberto Mazzanti, Ornella Fantappié, Yukkio Kamimoto, Zenaida Gatmaitan, Paolo Gentilini, Irwin M. Arias – 1 July 1994 – To study the effect of bile acids on P‐glycoprotein–mediated drug transport, we performed experiments using multidrug resistant cells and rat canalicular membrane vesicles. Cellular accumulation and efflux of rhodamine 123 were measured in drug‐resistant cells by means of computerized quantitative image analysis and fluorescence microscopy.

Yuichi Fujii, Michael E. Johnson, Gregory J. Gores – 1 July 1994 – Sinusoidal endothelial cell injury plays a pivotal role in anoxia/reoxygenation liver damage. However, the mechanisms culminating in anoxia/reoxygenation endothelial cell injury remain unclear. Our aims were to determine whether anoxia/reoxygenation injury of sinusoidal endothelial cells causes mitochondrial dysfunction.

Sarah Shefer, Gerald Salen, John Bullock, Lien B. Nguyen, Gene C. Ness, Zhihong Vhao, Peter F. Belamarich, Indu Chowdhary, Susan Lerner, Ashok K. Batta, G. Stephen Tint – 1 July 1994 – We investigated hepatic cholesterol homeostasis in four homozygous sitosterolemic subjects from two unrelated families who showed enhanced absorption, diminished removal and increased tissue and plasma concentrations of sitosterol (24‐ethyl cholesterol).

Jean Michel Heard – 1 July 1994 – The liver represents a model organ for gene therapy. A method has been developed for hepatic gene transfer in vivo by the direct infusion of recombinant retroviral vectors into the portal vasculature, which results in the persistent expression of exogenous genes. To determine if these technologies are applicable for the treatment of hemophilia B patients, preclinical efficacy studies were done in a hemophilia B dog model.

Li‐Jun Mi, Jaygonda Patil, William E. Hornbuckle, Paul J. Cote, John L. Gerin, Bud C. Tennant, Fiorenzo Paronetto – 1 July 1994 – We analyzed the DNA ploidy and the nuclear size of hepatocytes within hepatocellular carcinoma, putative preneoplastic (clear cell and basophilic foci) and adjacent non‐neoplastic liver in 30 woodchucks neonatally infected with the woodchuck hepatitis virus. In livers from control woodchucks, in clear cell foci and in most chronic portal hepatitis, the hepatocytes were diploid, with less than 10% tetraploid cells.

Kenji Ikeda, Satoshi Saitoh, Isao Koida, Akihito Tsubota, Yasuji Arase, Kazuaki Chayama, Hiromitsu Kumada – 1 July 1994 – To elucidate the detectability of small hepatocellular carcinoma by various imaging modalities, we performed digital subtraction angiography, computed tomographic arterioportography and carbon dioxide‐enhanced ultrasonography. Of 76 patients with a small hepatocellular carcinoma of 2 cm or less in maximum diameter, 61 underwent digital subtraction angiography, computed tomographic arterioportography and enhanced ultrasonography at the same time.
