    Description / Table of Contents: Summary We measured the concentrations of serum calcium and 25-hydroxy-vitamin D in a patient with hypervitaminosis D during 3 months of therapy directed toward correcting the hypercalcemia. Serum calcium could not be maintained at normal concentration without specific therapy until 9 weeks after vitamin D was discontinued. Concentration of 25-hydroxy-vitamin D at the time was 285 ng/ml, approximately half of the value measured three weeks after withdrawal of vitamin D. Serial measurements of the concentration of 25-hydroxy-vitamin D seem to be a useful means of assessing the degree of intoxication in patients with hypervitaminosis D.
    Notes: Zusammenfassung Wir verfolgten die 25-Hydroxy-Vitamin D- und Calciumspiegel im Serum einer Patientin mit Vitamin D-Überdosierung unter calciumsenkender Therapie über drei Monate. Normale Serumcalciumspiegel fanden sich in einem therapiefreien Intervall erst 9 Wochen nach Beendigung der Vitamin D-Einnahme. Der 25-Hydroxy-Vitamin D-Spiegel lag zu diesem Zeitpunkt mit 285 ng/ml fast um die Hälfte niedriger als zu Beginn der Beobachtungszeit drei Wochen nach Absetzen des Vitamin D. Verlaufskontrollen der 25-Hydroxy-Vitamin D-Spiegel sind offenbar geeignet, das Ausmaß einer Vitamin D-Intoxikation abzuschätzen.

    Notes: Abstract Solid-phase extraction (SPE) has been used to enrich organic micropollutants (hydrophobic chlorinated and polycyclic aromatic hydrocarbons, CHC and PAH) from coastal water samples and to systematically study the influence of humic substances (HS) on SPE. A reversed phase (RP) system with high flow rates (rapid chromatography, RC) was used to show the basic adsorption principles and interaction processes which influence the enrichment of organic compounds. A model humic substance was found to hinder the enrichment of individual hydrophobic micropollutants (MP), depending on their octanol-water distribution coefficient P OW. This effect was found to be lower with natural humic substances. For longer contact time between water sample and adsorption material, the pollutant/humic substance bonding proved to be reversible.

    Description / Table of Contents: Zusammenfassung Das hydrodynamische und thermische Verhalten einer Flüssigmetallströmung wurde bei benetzter und nichtbenetzter Rohrwand untersucht. Als Modellfluid diente Quecksilber. Bei laminarer Strömung wurden keine hydraulischen Anomalien nachgewiesen. Beim benetzten Rohr wurde eine ständige Durchmesserveränderung und Erhöhung der Rauhigkeit beobachtet, die auf die Bildung und Abtragung einer Amalgamschicht an der Wand zurückzuführen ist. Im Rahmen der Wärmeübergangsuntersuchungen zeigen im laminaren Strömungsgebiet die im benetzten Rohr gemessenen Wärmeübergangskoeffizienten sehr gute Übereinstimmung mit der Theorie. Im turbulenten Bereich sind die Meßergebnisse mit zuverlässigen Werten der Literatur bei nichtbenetztem Rohr vergleichbar. Eine Beeinflussung des Wärmeübergangs durch unterschiedliche Benetzungszustände ist auszuschließen.
    Notes: Abstract In wetted and nonwetted tubes the hydrodynamics and heat transfer of liquid metal flow were investigated. Mercury was used as test fluid. For the laminar flow no hydraulics anomalies were indicated. In the case of the wetted tube a steady change of diameter and an increase of the surface roughness were observed. This is due to the formation and removing of a viscous amalgam layer at the tube wall. In the laminar region heat transfer measurements show very good agreement with theory. In the turbulent region the experimental results are comparable with heat transfer coefficients valid for the nonwetted tube published in literature. The influence of different surface contact conditions to heat transfer can be excluded. A thermal contact resistance could not be found.

    Notes: Abstract Vaginal sensitivity was investigated in a group of 60 volunteers by means of an electric stimulus and under nonerotic conditions. In comparison to the dorsum of the hand, the genital area has a low sensitivity for electric stimuli (p 〈0.001). Of the genital area, the vaginal wall measured 2 to 4 cm from the vaginal introitus was found to be very insensitive (p 〈0.05). Within the vaginal wall a relatively sensitive position to electric stimuli could be detected at the “12-hr position” (the anterior vaginal wall) (p 〈0.001). The study provides data underscoring previous anatomical and clinical research findings regarding the sensitivity of the anterior vaginal wall. The inefficiency of coitus for inducing female orgasm is discussed.
