    Notes: Summary The stereologioal model and the base-line data of normal human liver needle biopsy-specimens are presented. Four reference systems were introduced: 1 cm3 of liver tissue, 1 cm3 of hepatoeyte, 1 cm3 of hepatocytic cytoplasm and the volume of an average “mononuclear” hepatocyte. The sampling was done at three levels of magnification (1,000 ×, 5,000 × and 10,000 ×). A lobular differentiation was not considered. The baseline data show strikingly small variations (s.e. less than 10%) within the individual biopsy specimen and within the group of four biopsies. There is no principal difference between human beings presented here, rats, mice and dogs. Only the mean individual volume of human hepatocytes is clearly larger than in rodents. The problems and limitations of stereological work on liver biopsy specimens are discussed.

    Description / Table of Contents: Summary The clinical course of a 26 year old female patient with acute liver necrosis and coma due to hepatitis B is reported. The disturbances of conciousness had improved. The patient survived 41 days after the beginning of the coma and developped livercell regeneration and an acute post-hepatitic liver cirrhosis. As a grave complication a septicemia with aspergillus was observed. The patient died because of gastro-intestinal hemorrhage. At autopsy there were no signs of brain edema. The treatment consisted in: daily infusions with coenzyme A, nicotinamid-adenin-dinucleotide, alpha lipoic acid and cocarboxylase to improve the metabolic disorders and the clinical picture; mannitol intravenously to prevent and to treat cerebral edema; 33 charcoal-hemoperfusions to remove toxic substances of acute liver failure. Treatment of the aspergillus infection with 5-fluorocytosine and amphotericine B and infusion of concentrated ascites led to a decompensation of liver functions. From this observation the following conclusions can be drawn: after an acute viral hepatic necrosis, new synthetic functions and improvements of the disturbed intermediary metabolism in regenerated liver-cells can eventually be seen only after twenty-four to thirty days. With systematically applicated mannitol infusions it is possible to treat cerebral edema effectively.
    Notes: Zusammenfassung Es wird der Verlauf einer durch Hepatitis B bedingten, akuten Lebernekrose mit Coma bei einer 26jährigen Patientin beschrieben. Die Bewußtseinsstörung besserte sich. Die Patientin überlebte 41 Tage und entwickelte Leberzellregenerate und eine akute posthepatitische Leberzirrhose. Im Verlauf trat als schwere Komplikation eine Pilzsepsis auf. Die Patientin starb an einer Magendarmblutung. Bei der Autopsie fand sich kein Hirnödem. Die Behandlung beständ in täglichen Infusionen von Coenzym A, Nikotinamid-adenin-dinukleotid, alpha-Liponsäure und Cocarboxylase zur Besserung von metabolischen Störungen und klinischem Bild; Mannitol intravenös, zur Verhinderung und Behandlung des Hirnödems; 33 Kohlehämoperfusionen, zur Entfernung toxischer Substanzen. Behandlung der Aspergillus-Infektion mit 5-Fluorocytosin und Amphotericin B und Infusion des konzentrierten Ascites führten zu einer Dekompensation der Leberfunktionen. Aus dieser Beobachtung können folgende Schlüsse gezogen werden: Nach einer akuten viralen Lebernekrose kann es erst nach 24–30 Tagen zur Wiederaufnahme synthetischer Funktionen und zur Besserung des gestörten Intermediärstoffwechsels in regenerierten Leberzellen kommen. Mit systematischer Mannitol-Therapie ist es möglich, das Hirnödem wirksam zu bekämpfen.

    Notes: Summary In this randomized, controlled multicenter trial we evaluated the effects of recombinant interferon-α2b on galactose elimination capacity and histological activity index in 88 patients with chronic active hepatitis non-A/non-B. Forty-five patients were randomly assigned to treatment with interferon at 1.5 × 106 U three times per for 1 year; 43 patients were assigned to no treatment. A complete response (normalization of alanine aminotransferase) was observed, respectively, in 47% and 5% of the two groups (P〈0.006); 47% of these patients suffered a relapse. Thus 22% of patients had a sustained response. Histological activity decreased significantly in responders (P〈0.04) while the biopsy score did not change significantly in nonresponders. In contrast, galactose elimination capacity — a surrogate marker for survival in chronic active hepatitis — was not affected by response to treatment. None of the parameters evaluated, including hepatitis C virus RNA, was able to predict response or relapse. We conclude that low-dose interferon treatment for 1 year is as effective as the recommended treatment schedule.
