    Notes: Summary Survival of mice after lethal doses of a lyophilizate fromAmanita phalloides (‘death cap’) was markedly increased by single doses of ethanol applied 30 min before or 5 min after the mushroom. Hepatic histopathological damage (confluent necrosis) was largley prevented. Acute, but not chronic, consumption of ethanol may thus influence favorably the outcome of death cap poisoning and should be taken into consideration in the evaluation of therapeutic measures.

    Notes: Abstract Pretreatment with zinc aspartate increased the survival rate of mice poisoned with a lyophilisate from the mushroomAmanita phalloides (APL). In the livers of the zinc-treated animals, confluent necrosis was cleared earlier. Zinc also prevented the reduction of brain noradrenaline caused by the mushroom as well as the rise of brain dopamine and brain weight.d-Penicillamine also protected against the lethal effects of APL. The survival afforded by zinc pretreatment was marginally ameliorated by additional oxygenation.

    Notes: Summary The effect of 2 fixatives, (1) s-Collidin buffered OsO4, (2) phosphate buffered OsO4, on the liver cell was studied by morphometric analysis. After fixation with solution 2, large areas of smooth endoplasmic reticulum were covered by electron-opaque deposits of glycogen. No such masking was noticed by using solution 1. Other cell organelles showed no significant differences in their relative volumes. By using fixative solution 2, decrease in glycogen can simulate relative volume increase of the smooth endoplasmic reticulum.

    Description / Table of Contents: Summary The occurrence of anti-HBcAg antibodies in the blood as determined by indirect immunofluorescence and its relation to the occurrence of HBsAg in the cytoplasm and of HBcAg and IgG in the nuclei of hepatocytes were studied in the following groups of patients (total of 123 biopsies): I. 64 HBAg-negative patients with various liver diseases; II. 51 HBAg-positive patients without therapeutical immunosuppression (6 acute hepatitis, 10 nonspecific reactive and 10 chronic persistent hepatitis, 19 chronic aggressive hepatitis, 6 „Hippie“-hepatitis); III. 8 kidney transplant recipients. It could be shown that nuclear IgG is found only if both parameters can be demonstrated at the same time: HBcAg in liver cell nuclei and anti-HBcAg antibodies in the serum in titers higher than 1:64. Accordingly, all types of hepatitis with excess formation of nuclear HBcAg (early phase of acute hepatitis, chronic aggressive hepatitis and chronic non-aggressive forms with generalized core formation, i.e. carrier state or chronic persistent hepatitis of the HBc type) may show nuclear fluorescence for IgG. All forms of hepatitis B without detectable core formation (acute hepatitis in the elimination phase, chronic nonaggressive hepatitis with isolated HBsAg expression, i.e. carrier state or chronic persistent hepatitis of the HBs type, posthepatitic phase) do not present nuclear IgG despite eventual anti-HBcAg formation. Finally, lack of anti-HBcAg or very low titers associated with lack of IgG in hepatocytic nuclei do not exclude generalized core formation in liver cell nuclei in chronic persistent hepatitis of effectively immunosuppressed patients. Although the demonstration of nuclear IgG has several diagnostic and prognostic consequences in common with the demonstration of HBcAg, a specific search for the core antigen in the tissue is needed for the correct appraisal of the HBcAg- and HBsAg tissue expression pattern and the associated disease.
    Notes: Zusammenfassung Mit der indirekten Immunfluorescenz-Methode wurden anti-HBcAg-Antikörper im Blut bestimmt und ihr Vorkommen in Beziehung gesetzt zum Nachweis von HBsAg im Zytoplasma und HBcAg sowie IgG im Zellkern in Leberbiopsien von insgesamt 123 Probanden. Das Untersuchungskollektiv umfaßte 64 HBAg-seronegative Patienten mit unterschiedlichen Leberkrankheiten, 51 HBAg-seropositive Patientenohne therapeutische Immunsuppression (darunter histologisch 6 akute Hepatitis, 10 unspezifisch reaktive Hepatitis, 10 chronisch persistierende Hepatitis, 19 chronisch aggressive Hepatitis und 6 „Hippie“-Hepatitis) sowie 8 sero-positive immunsupprimierte Nierentransplantat-Empfänger. IgG war immer dann darstellbar, wenn gleichzeitig die Leberzellkerne positiv ausfielen für HBcAg und anti-HBcAg-Titer im Blut den Titerwert von 1:64 überstiegen. So ließen alle Hepatitisformen mit ausgeprägter nukleärer Core-Bildung, wie Frühphase der akuten Hepatitis, chronisch aggressive Hepatitis und nicht-aggressive Formen mit generalisierter HBcAg-Expression (z.B. chronisch persistierende Hepatitis oder Trägerstatus vom HBc-Typ) nukleäres IgG erkennen. Alle Varianten der Hepatitis Bohne faßbares HBcAg im Gewebe (akute Hepatitis in der Eliminationsphase oder posthepatitisch, chronisch persistierende Hepatitis und Trägerstatus vom HBs-Typ) hingegen waren negativ auf nukleäres IgG und zwar auch in Fällen mit nachweisbaren anti-HBc-Antikörpern im Blut. Bei effektivimmunsupprimierten Patienten mit chronisch persistierender Hepatitis schließlich war IgG im Gewebe negativ und die Bluttiter für anti-HBc waren negativ oder sehr niedrig, so daß in diesen Fällen eine generalisierte nukleäre Core-Expression nicht erfaßt werden konnte. Wenn auch dem Nachweis von IgG im Lebergewebe eine gewisse diagnostische und prognostische Bedeutung zuzusprechen ist, ist doch der spezifische Nachweis von HBcAg im Gewebe in der Ermittlung des HBc- und HBs-Ag-Expressionsmusters im Gewebe und damit in der korrekten Einstufung einer Hepatitis B-Virusinfektion überlegen.

    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: Abstract The activity of single neurons was recorded in area 5 while monkeys made parallel arm movements within different parts of space in an instructed-delay reaching task. In this task: (1) extrinsic variables, such as the direction of movement, were dissociated from intrinsic ones, such as the joint configuration used to perform the movements; and (2) the early neural events related to the presentation of the visual stimulus concerning movement direction were dissociated in time from the later events linked to the execution of movement. Under these experimental conditions, cell activity in area 5 changed so that the population of preferred direction vectors of parietal neurons rotated in space in a way which predicted the rotation of the arm necessary to perform the task. This rotation occurred both during the “instructed-delay time,” when the monkey waited for the “go-signal,” and during the time interval surrounding the onset of movement. This suggests that reaching to visual targets in area 5 is coded by a mechanism combining somatic and visually derived information within a shoulder- or body-centered coordinate system and that instructed-delay time activity in area 5 reflects not only the composition of the direction signal for reaching but also the spatial configuration of the arm.

    Notes: Abstract From 50 published cases of hepatocellular adenoma (HCA) in glycogen storage disease, type I (GSD I) some characteristic features may be deduced: 1. The male: female ratio was 2∶1. This sharply contrasts to HCA of other origin which shows a strong female preponderance. 2. The histology of adenomas largely corresponded to other adenomas, except for the appearance of Mallory bodies, accompanied by neutrophilic inflammation and a peculiar lamellar fibrosis. This observation is of particular interest because Mallory bodies have so far not been described in adenomas but are a well established feature in hepatocellular carcinoma of any aetiology. 3. Adenomas had a tendency to regress after continuous nocturnal intragastric feeding, although not all cases responded favourably. 4. Ten cases of hepatocellular carcinoma (HCC) are recorded in GSD I in literature, whereby in half of them transition from HCA into HCC seems likely. 5. The similarity in clinical presentation and evolution with oestrogen-induced tumours is striking. Pathogenesis of adenoma formation in GSD I is not understood. Experimental evidence and the clinical observation of regression after correction of the metabolic imbalance suggest three possible candidate mechanisms: (1) a glucagon/insulin imbalance; (2) cellular glycogen overload; and (3) proto-oncogene activation. Evidence in favour of these three mechanisms from experimental studies and observations in humans are briefly reviewed.

    Notes: Aim To test the efficacy and safety of recombinant granulocyte-macrophage colony-stimulating factor (rHuGM-CSF) in the treatment of chronic cutaneous leg ulcers.Methods Five patients with chronic cutaneous leg ulcers were recruited for this 4-month study using only rHuGM-CSF to treat the ulcers. One patient had a neuropathic-diabetic ulcer, and four had long-standing vascular leg ulcers.Results The patient with the neuropathic diabetic ulcer showed complete healing after 1 month of treatment. The other four patients with vascular leg ulcers with a long history of ulceration had a poor prognosis for healing. The first, with three venous ulcerative lesions, presented complete resolution of one ulcer and stabilization of the other two; the second and third patients, with large vascular ulcers, improved with more then 50% reduction of the mean diameter of the ulcers; the fourth patient, with one large venous ulcer, did not show any improvement.Conclusions Pathogenesis, size and duration of the ulcers seemed to be the most important parameters regarding wound repairing capability of rHuGM-CSF. None of the ulcers increased in size and none of the patients developed clinical side-effects or peripheral blood cell count abnormalities during the treatment. All the results described were stable after 6 months of follow up. The absence of peripheral leucocyte count variation and the size-dependent therapeutic effect indicate that the drug exercises local rather than systemic actions.
