    Notes: Abstract Four volcanoes form Terceira, one of the islands of the Azores group; three contain both basaltic and peralkaline and one only peralkaline rocks. A recently active basaltic fissure zone trends NW-SE across the island. The rocks fall into the alkaline olivine basalt suite although some young basalts are of transitional affinity. The geochemistry shows two general basaltic series: 1) undersaturated, found in lavas of the oldest volcano and in some recent fissure zone basalts and hawaiites; 2) saturated, found in the younger basaltic lavas. Since the emergence of Terceira there has been a contemporaneity of basalt and salic peralkaline lavas. The younger rocks show a bimodal composition distribution, the most voluminous compositions being alkali olivine basalt and comendite with negligible volume in the benmoreite-trachyte range. Two processes appear viable for the derivation of voluminous oversaturated peralkaline rocks: 1) partial melting of upper mantle material giving small magma batches of contrasting composition or 2) fractionation from a transitional basaltic parental magma.

    Description / Table of Contents: Zusammenfassung In Homogenaten frischer menschlicher Haut wurden die Aktivitäten der Laktatdehydrogenase (LDH), der Glukose-6-phosphat-Dehydrogenase (G-6-PDH), der “sauren” Phosphatase (AcP) und der “Leucinaminopeptidase” (LAP) nach Inkubation mit Hydrocortison, Hydrocortison-acetat oder Hydrocortison-17-butyrat bestimmt. Die Konzentration des Steroids betrug in allen drei Fällen 2,75 mMol/l. Hydrocortison-butyrat bewirkte eine signifikante Hemmung der LDH-, G-6-PDH- und AcP-Aktivitäten. Hydrocortison und Hydrocortison-acetat zeigten nur bei der G-6-PDH-Aktivität eine signifikante Hemmwirkung. — An reiner G-6-PDH aus Hefe war die Hemmwirkung von Hydrocortison-butyrat signifikant stärker als die Hemmwirkung von Hydrocortison und Hydrocortison-acetat. Zeit-Wirkungs-Diagramme zeigten, daß Hydrocortison-butyrat vom Beginn der Inkubation an wirksam ist (keine Esterspaltung). — Die Ergebnisse unterstützen die Annahme, daß Hydrocortison-butyrat eigene biochemische-pharmakologische Effekte besitzt und daß es nicht nur als veresterte Transportform von Hydrocortison angesehen werden darf.
    Notes: Summary In fresh human skin homogenates, the activities of four enzymes, lactate dehydrogenase (LDH), glucose-6-phosphate dehydrogenase (G-6-PDH), “acid” phosphatase (AcP), and “leucine aminopeptidase” (LAP) were assayed following an incubation with hydrocortisone, hydrocortisone acetate, or hydrocortisone-17-butyrate, respectively. Concentration of the three compounds measured 2.75 mMol/l. Hydrocortison butyrate inhibited LDH-, G-6-PDH-, and AcP-activities. Hydrocortisone and hydrocortisone acetate exerted a significant inhibitory action only in the case of G-6-PDH-activity.—On pure G-6-PDH from yeast, the inhibition exerted by hydrocortisone butyrate was significantly stronger than the inhibition exerted by the two other steroids. Time/action diagrams revealed the fact that hydrocortisone butyrate is superior to the other two compounds from the beginning of the incubation period.—The data sustain the assumption that hydrocortisone butyrate exerts biochemical-pharmacological actions of its own and that it may not be considered just as an esterified transport form of hydrocortisone.

    Notes: The cheapness of modern minicomputers coupled with the need for rapid and accurate output of X-ray fluorescence analytical data makes the use of computers almost obligatory. The minicomputer has the advantages of immediate availability of results over other methods. In laboratories with an annual output of less than 10 000 determinations the on-line card -punch or magnetic-tape reader coupled through a terminal to a central computer is equally effective though slower.
