Hepatocyte growth factor induces proliferation and morphogenesis in nonparenchymal epithelial liver cells

Mark Johnson, George Koukoulis, Kunio Matsumoto, Toshikazu Nakamura, Anand Iyer – 1 June 1993 – Hepatocyte growth factor is the most potent mitogen known for hepatocytes, and increasing evidence suggests that hepatocyte growth factor plays an important role in liver regeneration. However, hepatocytes are not the only liver epithelial cell population that proliferates during regeneration. Experimental and clinical data indicate that the regenerative liver response also includes the participation of nonparenchymal epithelial cells.

Can the liver be induced to say no?

John W. Wiley – 1 June 1993 – The incubation of primary cultures of rat hepatocytes with lipopolysaccharide (LPS) or biologically active phorbol esters promotes the release of nitric oxide to the incubation medium. This process is the result of the induction of the Ca2+‐ and calmodulinindependent form of nitric oxide synthase. Both the release of nitric oxide to the incubation medium and the expression of nitric oxide synthase activity exhibited a lag period of about 45–60 min after cell stimulation.

The role of 16, 16‐dimethyl prostaglandin E2 on the intrahepatic biliary branches in dogs

Tetsuo Ohta, Takukazu Nagakawa, Yutaka Yoshimitsu, Hiromi Sanada, Luis Fonseca, Itsuo Miyazaki, Tadashi Terada – 1 June 1993 – We studied the effects of the oral administration of a stable prostaglandin E2 analog, 16,16‐dimethyl prostaglandin E2, on the intrahepatic biliary branches in a canine model. Obstructive cholestasis with a bacterial infection was induced surgically in two liver lobes in healthy mongrel dogs, and 16,16‐dimethyl prostaglandin E2 was administered orally.

Hepatic 60‐kD heat‐shock protein responses in alcoholic hepatitis

John Koskinas, Vivienne R. Winrow, George L. A. Bird, Johnson Y. N. Lau, Bernard C. Portmann, David R. Blake, Graeme J. M. Alexander, Roger Williams – 1 June 1993 – The precise mechanism of the pathogenesis of alcoholic hepatitis is unknown, but immune involvement may perpetuate and exacerbate the process. Heatshock proteins, normally protective, may be immunogenic and have been shown to induce antibody formation in some inflammatory conditions. Alcohol, cellular hypoxia and tumor necrosis factor, all involved in alcoholic hepatitis, are potent inducers of heatshock protein.

Influence of human leukocyte antigen matching on liver allograft survival and rejection: “The dualistic effect”

Peter Donaldson, James Underhill, Derek Doherty, Karen Hayllar, Roy Calne, Kai‐Chah Tan, John O'Grady, Derek Wight, Bernard Portmann, Roger Williams – 1 June 1993 – To date only one published large series of human leukocyte antigen matching and liver allograft survival exists, and considerable confusion has arisen about the advantage or disadvantage of human leukocyte antigen matching.

Diagnosis and follow‐up of small hepatocellular carcinoma with selective intraarterial digital subtraction angiography

Kenji Ikeda, Satoshi Saitoh, Isao Koida, Akihito Tsubota, Yasuji Arase, Kazuaki Chayama, Hiromitsu Kumada – 1 June 1993 – To clarify the angiographic features of small hepatocellular carcinoma, we performed digital subtraction angiography in 91 patients with hepatocellular carcinomas of 2 cm or less. Repeated digital subtraction angiography studies were performed in 25 patients whose first angiograms showed no tumor staining. Digital subtraction angiography showed hypervascular tumor staining in only 51 patients (56.0%).

Magnetic resonance imaging and different levels of Iron overload in chronic liver disease

Emilio Rocchi, Marco Cassanelli, Athos Borghi, Franco Paolillo, Marcello Pradelli, Giovanna Casalgrandi, Aldo Burani, Ennio Gallo – 1 June 1993 – The need for accurate and noninvasive evaluation of liver iron stores prompted us to evaluate the reliability of high‐field magnetic resonance imaging equipment in liver patients with low or moderate siderosis, given the poor results obtained using systems operating at low field strength in such cases.
