    Notes: In vivo activated T cells could be isolated from cerebrospinal fluid (CSF) of a patient suffering from chronic meningitis of unclear origin. Although the patient's skin reactivity to purified protein derivative (PPD) was negative, and peripheral T cells did not proliferate to this antigen in vitro, the majority of T cell clones from CSF specifically recognized PPD on either autologous or allogeneic HLA class II compatible macrophages. Remarkably, peripheral blood mononuclear cells potently suppressed the PPD-specific proliferate responses of healthy donors. The selective enrichment of oligoclonal IgG in the CSF but not in the patient's serum further indicated T and B cell responses lacking systemic feedback control. Analyses of a persisting immune stimulation in the CSF provide a potent diagnostic tool and may explain neurological complications as observed in a number of autoimmune diseases and chronic infections.

    Description / Table of Contents: Résumé Les caractéristiques géométriques de 380 pédicules vertébraux, compris entre T6 et L5, ont été analysées. Les différentes mesures ont été pratiquées directement sur les pièces anatomiques et sur leurs images radiographiques. Le diamètre horizontal et vertical du pédicule vertébral, son angle avec le plan transversal et sagittal, le diamètre transversal et ventrodorsal du canal rachidien et du corps vertébral ont été pris en considération. La longueur du pédicule seule, ainsi que sa longueur associée à celle du corps vertébral jusqu'au cortex ventral ont été mesurées le long de l'axe pédiculaire et sur une ligne parallèle à la ligne médiane. Les diamètres pédiculaires horizontaux et verticaux les plus étroits ont été mis en évidence aux niveaux compris entre T6 et T10. La corrélation entre la largueur pédiculaire et la dimension des vis utilisées en clinique est évidente. Sur le plan transversal, le pédicule forme un angle plus ou moins divergent à partir du corps vertébral, à l'exception de T12. Sur le plan sagittal le pédicule a une direction crâniale de T6 à L3 et légèrement caudale pour L5. La connaissance de la distance comprise entre la limite dorsale du pédicule et le cortex ventral du corps vertébral est très importante pour pouvoir insérer une vis avec sûreté. Cette distance est significativement plus grande le long de l'axe pédiculaire par rapport à une ligne parallèle à l'axe médian à tous les niveaux sauf pour T12.
    Notes: Summary The geometric properties of 380 vertebral pedicles, ranging from T6 to L5, were analysed. Measurement were made directly from the specimens as well as from roentgenograms. The parameters considered were the horizontal and vertical pedicle diameters, pedicle angles in the transverse and sagittal planes, and the transverse and anteroposterior widths of the spinal canal and vertebral body. In addition, the length of the pedicle and the length of the pedicle including the vertebral body to the anterior cortex were measured along the pedicle axis and in a line parallel to the midline of the vertebral body. The smallest horizontal and vertical pedicle diameters were found at vertebral levels from T6 to T10. The correlation between pedicle widths and screw dimensions is obvious. In the transverse plane, the pedicle angle diverged from the vertebral body at all levels, except at T12. In the sagittal plane, the pedicles were angled cephalad from T6 to L3 and slightly caudally at L5. Knowledge of the length of the pedicle to the anterior vertebral body cortex is very important for safe screw purchase. At all levels, with the exception of T12, this length was found to be significantly greater along the pedicle axis than along a line parallel to the midline of the vertebral body.

    Histochemical and microbiochemical demonstration of reduced pyruvate kinase activity in thioacetamide-induced neoplastic nodules of rat liver (1988)

    Notes: Summary A new method for the histochemical demonstration of pyruvate kinase (PK) activity was developed using a semi-permeable membrane and ATP-dependent phosphorylation of glucose coupled with tetrazolium reduction via glucose-6-phosphate dehydrogenase (G6PD) in order to investigate normal liver tissue nd neoplastic hepatic nodules induced by thioacetamide (TAA). A series of control reactions and comparison with microbiochemical analysis of microdissected lyophilised material were used to determine the specificity of the reaction. In agreement with earlier reports, an activity gradient in control liver decreasing from zone 3 to zone 1 was apparent both histochemically and after biochemical analysis. Liver neoplastic nodules induced by 25 weeks dietary thioacetamide administration and characterized by increased G6PD demonstrated a clear decrease in PK activity. In contrast, epithelial cells within areas of cholangio-fibrosis thought to be direct precursors for cholangioccllular tumour development were characterized by a strong increase. Comparison of the results with immunohistochemical and biochemical data from the literature indicate that the specific histochemical method described will be of great assistance in future assessment of disease and physiological alteration in activity of this key enzyme of glycolysis.

    Description / Table of Contents: Summary Badgers(Meles meles) were observed in captivity and found to be able build a heat source constructed from dry plant material brought into the burrow. Straw and hay (but not leaf litter) was reduced into small pieces by the animals and deposited in several layers. When simultaneously supplied with straw, hay und leaf litter, straw was clearly preferred. Leaf litter was the least favoured material.
    Abstract: Résumé Lors d'essais en enclos (tanière artificielle) on a pu mettre en évidence la faculté du Blaireau(Meles meles) de se constituer des sources actives de chaleur au moyen de matériaux végétaux secs qu'il introduit dans sa tanière. A cet effet, de la paille et du foin (non pas du feuillage) sont hachés et entreposés en des endroits définis; les couches sont interverties à plusieurs reprises. Lorsque de la paille, du foin et du feuillage sont présentés à volonté, la paille est clairement préférée. Le feuillage se retrouve en dernière position en ce concerne les trois matériaux de construction de nids.
    Notes: Zusammenfassung In Gehegeversuchen (Dachs-Kunstbau) konnte beim Dachs(Meles meles) die Fähigkeit nachgewiesen werden, mit eingetragenen trockenen Pflanzenmaterialien aktiv heizende Wärmespender einzurichten. Dazu wird Stroh und Heu (nicht aber Laub) zerkleinert (gehäckselt) und lokal gestapelt sowie mehrmals umgeschichtet. Bei gleichzeitigem Angebot von Stroh, Heu und Laub in beliebiger Menge wird Stroh deutlich bevorzugt. Laub steht hinsichtlich der Beliebtheit an letzter Stelle der drei Nistmaterialien.
