Hiroki Sakaguchi, Shuichi Seki, Hirohito Tsubouchi, Yasushi Daikuhara, Yoshiyuki Niitani, Kenzo Kobayashi – 1 May 1994 – Human hepatocyte growth factor has been purified from the plasma of patients with fulminant liver failure, but where this factor is produced in organs or cells of subjects with liver diseases is unknown. Therefore, we used a monoclonal antibody to human hepatocyte growth factor to stain cells in three normal and 29 diseased liver tissues by immunohistochemical techniques.

Howard S. Kaufman, Thomas H. Magnuson, Henry A. Pitt, Peter Frasca, Keith D. Lillemoe – 1 May 1994 – Calcium bilirubinate, palmitate, carbonate and phosphate have been identified in the cores of cholesterol and pigment gallstones, suggesting a role for precipitated calcium salts in the early events of gallstone formation. Previous studies that compared the calcium salt contents of cholesterol and pigment stones required destruction of gallstone structure.

Andreas Dällenbach, Ulrich Marti, Eberhard L. Renner – 1 May 1994 – In hepatocytes in vitro, Na+/H+ exchange, an important regulator of intracellular pH, is activated by epidermal growth factor, but its activity during liver regeneration in vivo is unknown. We therefore compared activity and regulation of Na+/H+ exchange in hepatocytes isolated after two‐thirds partial hepatectomy or sham surgery, respectively, by measuring intracellular pH (fluorimetry) and steady state Na+/H+ exchange mRNA levels (Northern blotting).

Yuji Watanabe, Gerhard P. Püschel, Andreas Gardemann, Kurt Jungermann – 1 May 1994 – The site of confluence of the artery and the portal vein in the liver still appears to be controversial. Anatomical studies suggested a presinusoidal or an intrasinusoidal confluence in the first, second or even final third of the sinusoids. The objective of this investigation was to study the problem with functional biochemical techniques.

Ibrahim Kassissia, Antoine Brault, P.‐Michel Huet – 1 May 1994 – The hepatic artery and portal vein vascularization of seven normal and seven cirrhotic rats was evaluated by means of the multiple‐indicator dilution technique using the flow‐limited model analysis. Injected 15‐μm microspheres were all trapped by the liver in normal and cirrhotic rats after portal vein and hepatic artery injections, ruling out the presence of intrahepatic shunts larger than 15 μm.

Steinbrecher, Lloyd R. Sutherland, C. Noel Williams, Helga Witt‐Sullivan, Lawrence J. Worobetz, Ruth A. Milner, Ian R. Wanless – 1 May 1994 – Ursodeoxycholic acid, a dihydroxyl bile acid normally present in human beings in minimal amounts, becomes incorporated into the bile salt pool when taken orally. In cholestasis, bile acids are retained in the liver and are hepatotoxic.

Akira Iizuka, Tatsuro Watanabe, Toshiyuki Kubo, Masahiro Yamamoto, Kazuo Ogawa, Tetsuo Ohkuma, Akira Kaji – 1 May 1994 – We investigated effects of various DNAs on duck hepatitis B virus replication in vivo. One‐day‐old ducks were infected intravenously with DHBV. Various DNAs were then injected intravenously, and duck hepatitis B virus levels were followed for up to 20 days after the inoculation.
