    The nonspecific clearance function of the reticuloendothelial system in patients with immune complex mediated diseases before and after therapeutic plasmapheresis (1985)

    Notes: Summary The nonspecific clearance function of the reticuloendothelial system (RES) in six patients with immune complex mediated systemic vasculitis was determined by the evaluation of the disappearance rate of technetium 99m labelled microaggregated human serum albumin colloid (MHAC) injected IV before and after therapeutic plasma exchange. Three patients with systemic lupus erythematosus (SLE) and one patient with immune complex vasculitis (ICV) exhibited a significant clinical improvement after plasmapheresis which was paralleled by an accelerated MHAC elimination rate following plasma exchange therapy. One patient with ICV and unresponsive to plasma exchange showed delayed MHAC elimination. In one patient with myasthenia gravis (MG), the elimination rate was not altered by plasmapheresis. The data obtained indicate that nonspecific clearance of the RES may be one effect of plasma exchange therapy in patients with immune complex mediated diseases.

    Notes: Synthesis of Bipolar Ion Exchange ResinsSyntheses of weakly acid/strongly basic and weakly acid/weakly basic bipolar ion exchange resins with varying acid and basic capacities via subsequent introduction of the exchange active groups in suitable crosslinked skeletal polymers are described.Methylacrylate-styrene-divinylbenzene polymers of varying composition which can be quantitatively chloromethylated and subsequently fully aminated (trimethylamine) and partially saponified in one process step were used as starting polymers for weakly acid/strongly basic resins. The reverse route saponification of the ester groups first, followed by chloromethylation of the aromatic parts of the matrix and animation turned out to the possible, if at all, only for bipolar resins of strongly predominant basic character. The capacity parameters can be controlled through the composition of the matrix.Polymethylacrylates crosslinked with divinylbenzene served as polymer basis of the weakly acid/weakly basic bipolar ion exchange resins. The functionalization was achieved by partial aminolysis with polyamines (dimethylaminopropylamine, ethylenediamine, diethylenetriamine) and saponification with lyes. The number of basic and acid groups which can be introduced is governed primarily by the conditions of the aminolysis. The capacity parameters are controllable within a broad range by the procedures.

    Notes: Decomposition of tert.-Butyl Hydroperoxide by ZeolitesZeolites catalyze the decomposition of tert.-butyl hydroperoxide in the liquid-phase. Structure, cation and degree of ion-exchange influence the catalytic activity of the zeolithe. The highest rates of the decomposition were obtained by means of zeolites containing transition metal cations. It is possible to use the decomposition of tert.-butyl hydroperoxide, catalyzed by zeolites, for the epoxidation of olefins.

    Description / Table of Contents: The time-dependence of the permeation of methanol vapour through tenside-alginate foam lamels was determined by measuring the permeation, diffusion and solubility coefficients. Steady-state transport was found to occur only within narrow time limits. The agreement of calculated and experimental relationships between the coefficients suggest solution diffusion as proposed by BARRER. The transport mechanism can be explained by the place exchange theory and by the cluster theory according to LUCK.
    Notes: Für Tensid/Alginat-Schaumlamellen wurde der Durchtritt von Methanoldampf an Hand der Permeations-, Diffusions-und Löslichkeitskoeffizienten in Abhängigkeit von der Zeit ermittelt. Stationäre Transportzustände existieren nur in engen Zeitintervallen. Aus der Übereinstimmung zwischen den berechneten und experimentell ermittelten Koeffizienten-Beziehungen wird auf eine Lösungsdiffusion nach BARRER geschlossen. Der Transportmechanismus kann auf der Grundlage der Platzwechseltheorie sowie der Cluster-Theorie nach LUCK gedeutet wurden.
