    Notes: Résumé La cyclophosphamide est un agent efficace dans le traitement de la néphrose lipoidique et de plusieurs maladies rhumatoides qui attaquent la membrane basale glomérulaire (MBG). Des analyses chimiques ont été effectuées sur la MBG et sur la glycoprotéine urinaire chez des rats traités et non traités. Entre les deux groupes on n'a pas constaté de différence dans la composition des amino-acids, mais de grands changements dans le glucose et le galactose de la MBG et la glycoprotéine urinaire ont été observés chez les rats traités à la cyclophosphamide; cette drogue semble donc capable d'altérer l'intégrité de la MBG.

    Notes: Résumé La transformation lymphocytaire en phytohemagglutinine est étudiée chez des individus normaux, aussi bien que chez des malades souffrant de glomérulonéphrites aiguës et chroniques ainsi que de polyarthrite rhumatoïde. La réponse des glomérulonéphritiques fut conforme aux contrôles, les polyarthritiques eurent des réponses affaiblies. La transformation lymphocytaire est fortement réduite chez les patients sous immunosuppression.

    Notes: Summary The role of renal hydrodynamics on renal deposition of immune complexes was evaluated in acute serum sickness. Using i.v. radiolabelled antigen in rabbits under a variety of hydrodynamic alterations, these studies suggested that although intrarenal hydrodynamics influence renal deposition of immune complexes factors other than intrarenal hydrostatic pressure may be important.

    Notes: Résumé La néphrose produite expérimentalement chez le rat par l'amino-nucléoside, qui est analogue à la néphrose lipoïdique chez l'homme, est associée à des changements de la composition des glucides d'une glucoproteïne non collagène extraite des urines de rats ayant de la protéinurie. La composition des acides aminés n'a pas changé. Il se peut que cette glucoprotéine soit le résultat d'altérations dans la membrane basale glomérulaire, altérations qui amènent la protéinurie et peuvent être importantes dans la pathogénèse de la néphrose lipoïdique chez l'homme.

    Experimental autologous immune deposit nephritis in rats associated with mercuric chloride administration (1976)

    Notes: Summary Serial administration of mercuric chloride to rats was followed by development of antibodies to tubular basement membrane and renal tubular epithelial antigen (RTE) and glomerulonephritis characterized by granular deposits of host IgG, C3 and RTE along the glomerular capillary walls. The glomerular fixed antibody was directed against RTE. These studies suggest that tubular injury by mercury may lead to release of RTE and autosensitization and subsequent antibody production to this antigen result in formation of and glomerular deposition of circulating immunopathogenic complexes (RTE-anti-RTE) and glomerular morphologic alterations.

    The effect of procedural variables on TG, DTG and DTA curves of magnesite and dolomite (1991)

    Description / Table of Contents: Zusammenfassung TG-, DTG- und DTA-Kurven von Magnesit sind Ähnlich wie bei Kalzit [1] abhÄngig von den Versuchsparametern, besonders von Probenmasse, Aufheizgeschwindigkeit und Partialdruck von Kohlendioxid, obwohl das Ausma\ dieses Einflusses bei Magnesit geringer ist. Der erste Schritt der Zersetzung von Dolomit Ändert sich in einer ungewöhnlichen Weise durch Erhöhung des Partialdruckes von Kohlendioxid und deshalb unterscheidet sich der Einflu\ dieser Versuchsparameter (mit Ausnahme der Probenmasse) von dem, der bei Magnesit und Kalzit beobachtet wurde. Der zweite Schritt bei der Zersetzung von Dolomit ist stark von diesen Versuchsparametern abhÄngig und verlÄuft so, wie man es für eine mit Magnesia verdünnte Kalzitprobe voraussagen würde. Eine Gemisch aus Magnesit und Kalzit im VerhÄltnis 1∶1 verhÄlt sich ebenso, wie man es auf Grund des Verhaltens der einfachen Karbonate voraussagen würde, unterscheidet sich jedoch von dem des Dolomits.
    Notes: Abstract TG, DTG and DTA curves of magnesite are dependent on procedural variables, especially sample mass, heating rate and partial pressure of carbon dioxide, in a similar manner to those of calcite [1], although the magnitude of the effect is less for magnesite. The first stage of the decomposition of dolomite varies with increasing partial pressure of carbon dioxide in an anomalous manner and hence the effects of these procedural variables (except heating rate) are not similar to those observed for magnesite and calcite. The second stage of the decomposition of dolomite is, however, strongly dependent on these procedural variables and behaves in a manner that would be predicted for a sample of calcite diluted with magnesia. A 1∶1 molar mixture of magnesite and calcite also behaves as would be predicted from the behaviour of the single carbonates but differently from that of dolomite.

    Description / Table of Contents: Zusammenfassung Bei der Zersetzung von A.R. Calciumcarbonat bzw. Kalkstein wurde der Einflu\ der Versuchsparameter, einschlie\lich Probenmasse, Aufheizgeschwindigkeit, Partikelgrö\e und Partialdruck von CO2 auf den Verlauf der TG-, DTG- und DTA-Kurven untersucht. Diese Parameter haben einen deutlichen Einflu\ auf DTG und DTA, der sich in beiden FÄllen im gleichen Ausma\ bemerkbar macht. Der Einflu\ der Masse bzw. Tiefe einer unverdünnten Probe Äu\ert sich in einem Ansteigen des Partialdruckes von Kohlendioxid innerhalb des reagierenden Pulvers und wird als Bett-Tiefen-Effekt bezeichnet. Dieser Effekt kommt in Stickstoff besonders zur Geltung und tritt in Kohlendioxid in den Hintergrund. Inerte Verdünnungsmittel haben einen nur geringen Effekt auf die TG-Kurve aber eine Änderung der Zusammensetzung des inerten TrÄgergases verursacht VerÄnderungen, die auf der WÄrmeleitfÄhigkeit des Gases begründet sind. Wasserdampf verursacht, da\ DTG- und DTA-Signale bei niedrigeren Temperaturen auftreten.
    Notes: Abstract The effect of procedural variables, including sample mass, heating rate, particle size and partial pressure of carbon dioxide, on TG, DTG and DTA curves for the decomposition of A. R. calcium carbonate and limestone has been studied. Such variables have a marked effect, similar in magnitude for both DTG and DTA. The effect of sample mass, or depth of undiluted sample, is shown to be due to an increase in the partial pressure of carbon dioxide within the reacting powder and has been called the bed-depth effect. This effect is most pronounced in nitrogen but is much reduced in carbon dioxide. Inert diluents have little effect on the TG curves but changing the composition of the inert carrier gas causes variations which are correlated with the thermal conductivity of the gas. Water vapour causes a lowering of the DTG and DTA peak temperatures.
