J. Ricardo B. Pernambuco, Peter G. Langley, Robin D. Hughes, Satoru Izumi, Roger Williams – 1 December 1993 – Abnormalities of blood coagulation and fibrinolysis are a major part of fulminant liver failure. In this study, the key components of the fibrinolytic system were determined in 42 patients with this condition. Admission levels of plasma plasminogen activity were low (9.1% of normal), as to a lesser extent were the activities of its inhibitors α2‐antiplasmin (20.5% of normal) and C1 inhibitor (64% of normal).

Tomasz R. Kurzawinski, Alastair Deery, James S. Dooley, Robert Dick, Kenneth E. F. Hobbs, Brian R. Davidson – 1 December 1993 – In patients with obstructive jaundice due to biliary tract stricture a tissue diagnosis is essential because of the varied treatment options available. Radiological imaging of a biliary stricture may suggest that it is malignant, but only a tissue diagnosis can be conclusive. The difficulty of obtaining biopsy tissue has encouraged the use of cytology in this field.

When human hepatocyte growth factor prepared from the culture medium of human embryonic lung fibroblasts was intravenously injected into normal rats and rats after 70% hepatectomy, it was detected in hepatocytes but not in nonparenchymal cells isolated 30 min after injection.

Nelson Fausto – 1 December 1993 – In previous studies hepatocytes undergoing cell death by apoptosis but not normal hepatocytes in rat liver showed immunostaining for transforming growth factor β1 (TGF‐β1). Staining was much stronger with antibodies recognizing the pro‐region of TGF‐β1 than the mature peptide itself. Therefore we investigated the ability of both forms of TGF‐β1 to induce apoptosis in primary cultures of rat hepatocytes. Mature TGF‐β1 induced rounding up of the cells and fragmentation into multiple vesicles.

Genta, Boris Yoffe – 1 November 1993 – To gain new insights into the pathogenesis of hepatitis B virus–induced chronic liver disease, we have used nonisotopic in situ detection methods for the simultaneous analysis of hepatitis B virus DNA and antigens at the single‐cell level.
