    Description / Table of Contents: Summary 24 h-urine excretion of aldosterone-18-glucuronide was determined with and without preceding paper chromatography in patients with essential hypertension (n=50). Radioimmunoassay was performed with a highly specific antibody against aldosterone. Urine specimens determined without chromatography gave significantly higher values than aliquots which were estimated at the same time with chromatography. A highly significant correlation was found between the two methods (r=0.91,p〈0.0001). Without chromatography, mean over estimation in samples with concentrations in the low and middle range was on average 32 and 24% respectively, whereas aldosterone concentrations in the upper range showed a 14% over estimation. The RIA procedure for aldosterone without chromatography as here described is suitable for hypertension screening programmes to exclude known forms of primary hyperaldosteronism in which elevated aldosterone excretion rates have to be differentiated from values lying within the normal range.
    Notes: Zusammenfassung Es wurde die Aldosteron-18-Glucuronidausscheidung im 24 h-Urin von essentiellen Hypertonikern (n=50) mit und ohne vorhergehender Papierchromatographie beschrieben. Der Radioimmunoassay wurde mit einem hochspezifischen Aldosteronantikörper durchgeführt. Die ohne Chromatographie analysierten Urine lagen signifikant höher als die dazu parallel bestimmten Proben mit Chromatographie (p〈0,02). Es konnte jedoch eine hochsignifikante Korrelation zwischen den beiden Methoden nachgewiesen werden (r=0,91,p〈0,0001). In Bereichen niederer und mittlerer Konzentrationen lagen die ohne Chromatographie bestimmten Proben in Mittel um 32 bzw. 24% über denen mit Chromatographie analysierten; Aldosteronkonzentrationen im Bereich der oberen Norm ergaben ohne chromatographisches Verfahren durchschnittlich um 14% höhere Werte. Die beschriebene Methode zur Bestimmung der Aldosteronexkretion ohne Chromatographie erscheint zur Abklärung von Hypertonikern geeignet, bei denen primäre Formen des Hyperaldosteronismus von normaler bzw. hoch normaler Aldosteronsekretion differenziert werden müssen.

    Notes: Summary The silylating reagents BSTFA and MSTFA are along with methyl iodide +K2CO3 useful for the derivatisation of salicylic acid and acetylsalicylic acid prior to GLC determination. The determination of traces of salicylic acid in acetylsalicylic acid bulk using BSTFA and MSTFA led also to the slight hydrolysis of acetylsalicylic acid. A column chromatographic separation seems here also necessary. A 2 m glass 3% OV-17 on Varaport 30, 70–80 mesh, AW/DMCS column was used.

    Notes: Summary In a sample of Bengali Muslems from Dacca, haptoglobin, group-specific component, haemoglobin, adenosine deaminase, adenylate kinase, 6-phosphogluconate dehydrogenase, phosphoglucomutase, acid phosphatase and several other red cell enzyme type were studied. For most serum protein and red cell enzyme systems the gene frequencies are similar to those in other populations to the west of Bangladesh, but others suggest affinity with populations to the east.

    Notes: Summary Techniques for the ultrastructural demonstration of dehydrogenases in cerebral cortex are described. The best fixation for good fine structural preservation and retension of LDH and NADH-diaphorase was obtained by perfusion with a mixture of formaldehyde and glutaraldehyde and for SDH by perfusion with formaldehyde. Comparison of incubation conditions showed that consistent results were obtained using enzyme markers NBT and DS-NBT for LDH and NADH-diaphorase; DS-NBT was more satisfactory than NBT and BSPT for SDH. Penetration of incubation media was improved by Triton X-100; DMSO and ultrasonic treatment were less effective. The techniques enabled the first electron cytochemical demonstration of dehydrogenases in different elements of prefixed cerebral cortex. Ultrastructural sites of enzyme activities were localized within cristae and intermembrane spaces of mitochondria in nerve cell cytoplasm and its processes, oligodendrocytes and astrocytes. Authenticity of the ultrastructural sites was confirmed by four different control experiments.
