    Plasma renin activity and plasma aldosterone concentration in infants with various sodium intakes (1979)
    Springer
    European journal of pediatrics 132 (1979), S. 49-54

    Notes: Abstract Plasma renin activity (PRA) and plasma aldosterone concentration (PA) were measured in 20 healthy infants 2–12 months of age, after taking a commercial modified cow's milk formula with 8.2 mmol/l sodium for at least five days, and after at least five days on a home-made, undiluted acidified cow's milk formula with 12.6 mmol/l sodium. The mean sodium intakes were 1.20 and 1.87 mmol/kg of body weight per day respectively. The arithmetic means for the corresponding PRA were 6.16 and 1.08 ng/ml·h (difference not significant) and the corresponding arithmetic means for PA were 603 and 355 pg/ml, the difference being highly significant (P〈0.01). It is concluded that one has to consider the sodium intake in the milk formula when studying plasma aldosterone in infancy.

    Sorption of trace concentrations of gallium(III) and iodide ions on tin(II) hydroxide (1977)

    Description / Table of Contents: Zusammenfassung In der Arbeit werden Ergebnisse von Sorptionsmessungen für Ga3+- und j-Spuren an Zinn(II)-Hydroxid aus wäßrigen heterogenen Systemen berichtet. Zur analytischen Erfassung wurden radioaktives67Ga und 131 J verwendet. Die Stabilität von Zinn(II)-Hydroxid wurde durch Trübungsmessungen untersucht. Im pH-Bereich von 3–9 ist das Zinn(II)-Hydroxid als kolloide Suspension instabil. Ga3+ und J− verhalten sich bei der Adsorption unterschiedlich. Die adsorbierte Menge steigt mit zunehmender Kontaktzeit bei hohen pH-Werten von Gallium, bleibt jedoch für Jod unverändert. Die Unterschiede werden gedeutet durch die Annahme, daß Jod nur an der festen Oberfläche adsorbiert wird, während die Galliumionen auch in das Sorbens diffundieren können. Man könnte die Ergebnisse als verträglich mit einem porösen Doppelschichtmechanismus ansehen; ein solcher Mechanismus ist in der Literatur für wäßrige heterogene Oxidsysteme vorgeschlagen worden.
    Notes: Summary The results of sorption measurements for gallium (III) and iodide ion traces onto tin(II) hydroxide from aqueous heterogeneous systems are given. Since only tagged sorbate was used (67Ga and 1311), in the determination of sorption by radioactive tracer method, it was necessary to establish the pH interval of tin(II) hydroxide in/stability. This was done by a turbidimetric method and the pH region of instability between 3 and 9 was found. The sorption results indicate a difference in sorption ability of gallium(III) and iodide as it appears from the dependence of the amount sorbed on contact time between heterogeneous reactants (sorbentsorbate). The amounts sorbed increase with increasing contact times at higher pH values for Ga(III) but remain unaffected for iodide sorption. Thus the sorption of iodide ions seems to be restricted to the solid surface while the sorption results for gallium(III) indicate the diffusion of sorbate into sorbent as a possible parallel mechanism. Those processes could be taken as compatible with the porous-double-layer mechanism which has been proposed in literature for aqueous heterogeneous oxide systems.

    Notes: Zusammenfassung Der AgCl−-Austausch an gefällten Koagulaten in dem Bereich isoelektrischer Koagulation bei pAg 4,7 und pCl 4,7 wurde als Bruchteil der rekristallisierten Mole von Chlorid gemessen. Dieser Bruchteil wird nach 26 h Austausch bei allen Präzipitaten praktisch konstant. Drei Bereiche der Präzipitatalterung kann man unterscheiden: (a) Präzipitate, weniger als 10 min gealtert, tauschen vollständig aus (f=80–100%). b) Der Austausch von Präzipitaten, die länger als 10 min gealtert werden, nimmt kontinuierlich ab und wird (c) kleiner als 5% für Präzipitate, die länger als 3,2 Tage gealtert sind. Zufügung von NaNO3 in einer koagulierenden Konzentration (0,2 N) ändert den Austauschprozeß nicht wesentlich. Der Austausch ist für kleinere Konzentrationen an Chlor (pCl 3,5) niedriger als für höhere Konzentrationen (pCl l). Die Unterschiede im Austausch von verschieden gealterten Ausfällungen können durch Rekristallisation erklärt werden. Der Austausch an gealterten (groben) Präzipitaten ist vernachlässigbar, so daß der besonders „drastische“ Austausch an frischen Ausfällungen entweder durch Selbstdiffusion in kleine noch nicht gealterte Primärteilchen oder durch Rekristallsiation von Primärteilchen in sekundäre Aggregate über die Lösungsphase erklärt werden muß.

    Notes: The extent of DVB grafting onto cellulose fabric increases with total gamma radiation dose up to 10-15 kGy while it decreases with the radiation dose rate. A quantitative analysis of DVB grafting has been attempted by means of IR spectroscopy using the baseline method. Characteristic bands were selected in the spectra of copolymers, namely, the cellulose band at 1160 cm-1 and DVB band at 798 cm-1. The former band decreased and the latter increased with the degree of copolymerization, and the values were in accordance with the calibration straight line. An attempt to graft DVB onto cotton fabric previously grafted with styrene showed greater extent of copolymerization than with pure fabric.
