Karin Vanderkerken, Luc Bouwens, Eddie Wisse – 1 July 1990 – Pit cells, or large granular lymphocytes, with natural tumoricidal activity are found in the sinusoids of normal rat liver. Hepatic large granular lymphocytes are heterogeneous and can be subdivided into two subsets. These subsets were compared with peripheralblood large granular lymphocytes and were found to differ phenotypically and functionally.

Riccardo Volpes, Joost J. van den Oord, Valeer J. Desmet – 1 July 1990 – The in situ distribution patterns of intercellular adhesion molecule‐1 and human leukocyte antigen‐DR antigens were studied in serial sections of 61 liver biopsy specimens from patients with hepatitis B virus infection using immunohistochemical techniques.

Kiyoshi Inokuchi, Cooperative Study Group of Portal Hypertension of Japan – 1 July 1990 – To evaluate prophylactic surgery for esophageal varices, a prospective randomized controlled trial was begun in 1980 by the Japanese Research Society for Portal Hypertension. Methods of operation included selective shunts and nonshunting interruption procedures. One hundred and twelve Japanese patients, in whom endoscopic findings suggested risk of bleeding but who had no bleeding episode, were randomly allocated to the operated group of 60 patients or nonoperated group of 52 patients.

Bipin K. Sharma, Bruce R. Bacon, Robert S. Britton, Chanho H. Park, Christopher J. Magiera, Rosemary O'Neill, Nicholas Dalton, Patricia Smanik, Theodore Speroff – 1 July 1990 – These experiments were performed to characterize the relationship between lipid peroxidation and hepatocyte viability in iron overload. Hepatocytes were isolated from rats with chronic dietary iron overload and the effects of in vitro iron chelation on lipid peroxidation, cell viability and ultrastructure were studied over a 4‐hr incubation period.
