    Notes: Summary The relationships between nerve cell-glia-complexes (NGCs) and surrounding capillaries were studied by combined cytometric-cytophotometric methods in male mice up to 60 min after injection of 70 mg/kg of pentylenetetrazole (PTZ). The nuclear area in neurons from cortical layers IV and V of the motoric area 8 increased by 13%, and in neurons from the hypoglossal nucleus there was an increase of 23%, associated with phasic changes in the nuclear area of their glial satellites. The number of perfused capillaries increased in both brain regions and there was a 20%-elongation of erythrocyte-filled capillary segments. The cytoplasmic RNA content enlarged in the hypoglossal neurons but decreased in cortical neurons from area 8. Peptidergic neurons and their glial satellites (supraoptic nucleus) showed nuclear shrinkage. Fifty percent of these peptidergic neurons reacted by reduction of their cytoplasmic RNA content. The measured cell reactions seem to be specific for different groups of NGCs which were defined by their histotopography, their neuronal interconnections, and a prevalence of secretory or nonsecretory neurons.

    Description / Table of Contents: Zusammenfassung Die häufigste Form der Koagulopathie bei akuter Erwachsenen-Leukämie ist eine Verminderung von Fibrin stabilisierendem Faktor (Faktor XIII). Patienten mit deutlichem Faktor XIII-Mangel (FSF) (〈50%) wurden mit einem Faktor XIII-Konzentrat aus menschlicher Plazenta substituiert und die Plasmakonzentration von Faktor XIII im Verlauf bestimmt. Durch die Substitution war fast immer eine schnelle Normalisierung des Faktor XIII-Spiegels zu erzielen. 13 Verläufe von Patienten mit deutlichem Faktor XIII-Mangel mit Substitution und 11 mit normalem oder nur mäßig vermindertem Faktor XIII zeigten weniger Blutungskomplikationen als eine Vergleichsgruppe von 12 Verläufen von Patienten mit deutlichem Faktor XIII-Mangel ohne Substitution.
    Notes: Summary A decrease in fibrin stabilizing factor (factor XIII) is the most frequent coagulation disorder seen in adults with acute leukemia. Patients with prominent reduction of factor XIII (FSF) (〈50%) were substituted with a factor XIII concentrate from human placenta, and factor XIII plasma concentration and bleeding tendency were followed up during the course of the disease. After substitution plasma, factor XIII activity went up to normal levels in most of the patients. As compared to the course of 12 patients with distinct factor XIII reduction without factor XIII therapy, there were less bleeding complications in 13 courses of patients with prominent reduction of factor XIII substituted with factor XIII concentrate and in 11 with normal or only slightly reduced factor XIII levels.

    Notes: Summary In rat adipocyte plasma membranes the effects of methanol, ethanol, propanol-1 and butanol-1 on adenylate cyclase activity were studied in the absence (basal) and presence of maximally activating concentrations of 5′-guanylylimidodiphosphate [Gpp(NH)p; 10 μM] and NaF (3 mM). Basal adenylate cyclase activity increased maximally 2-fold at 0.03–0.3 M propanol or 0.01–0.1 M butanol, with increasedV max and essentially unchangedK m for ATP. In most experiments, methanol and ethanol had no measurable activating effect. Above appr. 0.3 M of all alcohols, basal adenylate, cyclase activity declined sharply below control values. Adenylate cyclase activity stimulated by Gpp-(NH)p was further increased severalfold by all alcohols in a concentration-dependent manner, with increasedV max and unchanged apparentK m for the guanyl nucleotide. The potency of the alcohols increased with chain length (1 through 4 carbons). The effect of the alcohols on Gpp(NH)p-stimulated adenylate cyclase activity was still found at concentrations where basal activity was already reduced. Adenylate cyclase activity stimulated by NaF was affected similarly but definitely less marked than Gpp(NH)p-stimulated activity. Hormone-stimulated adenylate cyclase activity expressed relative to basal enzyme activity remained essentially unaffected by the alcohols. Increase in absolute enzyme activity apparently reflected corresponding changes in basal adenylate cyclase activity. Above alcohol concentrations of 0.3 M both basal and hormone-stimulated enzyme activities were inhibited.
