    Description / Table of Contents: Summary In four cases of hairy cell leukemia a cytochemical polymorphism concerning acid phosphatase (AP) is evident. Any AP is lacking in all hairy cells of one case; only tartrate inhibitable AP is occurring in two cases; in another case tartrate resistant AP is found in high activity. Thus, the lack of tartrate resistant AP seems not to be an argument against hairy cell leukemia.
    Notes: Zusammenfassung Mit Hilfe zytochemischer Untersuchungen kann bei der Haarzell-Leukämie ein Polymorphismus der sauren Phosphatase (SP) nachgewiesen werden. In einem von vier untersuchten Fällen fehlt jegliche SP in den Haarzellen, bei zweien ist nur tartratsensible SP nachweisbar, im vierten tartratresistente SP in hoher Aktivität. Nach unseren Erfahrungen spricht das Fehlen tartratresistenter SP nicht gegen die Diagnose Haarzell-Leukämie.

    Description / Table of Contents: Summary Two cases of a so-called eosinophilic leukemia are described with regard to morphological and clinical aspects. These cases are concerning a special variant of acute myelosis characterized by the following items: high eosinophilia of the intra- and in part of the extramedullary infiltrates contrasted by a moderate or low blood eosinophil count; intra- and extramedullary blast cell proliferation with blastic leukocytosis; cytochemical atypism of the eosinophils: unusual naphthol-AS-D-chloroacetatesterase activity, strong PAS-reaction; disarrangement of granulogenesis as revealed by electron microscopy. The presented cases are similar to others, in literature classified as “eosinophilic leukemia”. In this context the problem of monophylic leukemia is discussed in consideration of results obtained by cytochemical analysis of extramedullary leukemic infiltrates.
    Notes: Zusammenfassung Zwei Fälle einer sogenannten Eosinophilenleukämie werden hinsichtlich morphologischer und klinischer Aspekte beschrieben. Dabei handelt es sich um eine spezielle Form akuter Myelosen, die durch folgende Besonderheiten gekennzeichnet ist: hohe Eosinophilie der intra- und teilweise auch extramedullären Infiltrate bei relativ geringer Bluteosinophilie; intra- und extramedulläre Blastenproliferation mit starker Ausschwemmung; kennzeichnende zytochemische Atypien in Form einer ungewöhnlichen Aktivität der Naphthol-AS-D-chloroacetat-esterase und einer stark positiven PAS-Reaktion; besonders elektronenmikroskopisch deutlich sichtbare Dissozation und teilweise Arretierung der eosinophilen Granulogenese. — Die mitgeteilten Fälle zeigen Übereinstimmungen mit anderen, in der Literatur teilweise ebenfalls als “Eosinophilenleukämie” klassifizierten Formen. In diesem Zusammenhang wird die Problematik monophyler Leukosen unter Berücksichtigung der durch die zytochemische Analyse exakt bestimmbaren Differenzierung extramedullärer leukotischer Infiltrate diskutiert.

    Description / Table of Contents: Zusammenfassung Es wird ein Verfahren beschrieben, bei dem durch Soxhlet-Extraktion, Reinigung des Extraktes an Aluminiumoxid und Messung der Extinktion im Ultraviolett-Gebiet summarisch der Gehalt an polycyclischen, aromatischen Kohlenwasserstoffen in Rußen erfaßt wird. Die Extinktionsmeßwerte bei 7 Wellenlängen werden auf gleiche Bedingungen umgerechnet und als Extinktions-Kennzahlen bezeichnet. Ihr Mittelwert (Hauptkennzahl) kennzeichnet den Gehalt an polycyclischen, aromatischen Kohlenwasserstoffen eines Rußextraktes mit einer Zahl. Hauptkennzahlen unter 1 zeigen extrem niedrige, zwischen 1 und 10 geringe und zwischen 10 und 100 mäßige Konzentrationen an.
    Notes: Abstract Soxhlet extraction, purification of the extract on alumina and determination of ultraviolet absorbance allow to estimate summarily the amount of polycyclic aromatic hydrocarbons in a soot sample. The values of the absorbance measurements at seven wavelengths are calculated on the same conditions and are called absorbance numbers. Their average value (chief-absorbance-number) characterizes the amount of the polycyclic aromatic hydrocarbons of a soot extract with a single number. Chief-absorbance-numbers below 1 mean extremly small, between 1 and 10 small and between 10 and 100 moderate concentrations.

    Effect of ethanol on pancreatic and biliary secretions in humans (1973)

    Notes: Abstract The effect of various doses of ethanol on pancreatic and biliary secretions was studied in normal subjects and in patients with alcoholic pancreatitis. The composition of duodenal aspirates after ethanol administration was compared to that obtained after isotonic saline administration. A multilumen tube was used to perfuse a nonabsorbable marker (phenol red) into the duodenum, to collect duodenal secretions, and to perfuse saline or ethanol 45 cm beyond the ligament of Treitz. After the equilibration period, three 20-minute basal collections were obtained, followed by nine more collections after ethanol was started. Jejunal perfusion of isotonic (1.39%) alcohol, at rates at which no significant blood ethanol levels could be detected, did not cause changes in pancreatic or biliary secretions in either group. On the other hand, jejunal or intravenous alcohol administration in doses of 1 g/kg body weight caused marked reductions in volume and outputs of pancreatic enzymes, bicarbonate, and bile salts. The decrease in outputs was accompanied by a corresponding diminution in concentrations. The changes observed indicate that acute administration of large doses of ethanol causes rapid changes in the composition of duodenal aspirates in humans, which cannot be totally explained by postulating a spasm of the sphincter of Oddi.

    Affiliative, playful, and homosexual interactions of adult female lowland gorillas (1978)

    Notes: Abstract Over a period of seven months four wild born adult female lowland gorillas were observed under semi-natural captive conditions. Thirty instances of contact interactions were recorded during 80 hours of observation. These interactions were segregated into categories operationally defined as connoting playful, homosexual, and affiliative activities. During observation periods the animals' labial tumescence was rated and the stage of the cycle was estimated. Metacommunicative signals were involved during playful interactions which resembled social rough-and-tumble play. Sexual interactions included partner positioning, thrusting, and usually were accomplished through ventral-ventral genital approximations. Sexual activity was also significantly related to cycle state. Contact interactions appeared to represent a specification and elaboration of a trend revealed through measures of proximity.

    Description / Table of Contents: Zusammenfassung In Formaldehyd-Äthandiol-Polymeren eingebautes Äthandiol wird durch Umsetzung mit siedendem Essigsäureanhydrid-Perchlorsäuregemisch in Äthandioldiacetat übergeführt, das nach Erkalten der Reaktionslösung gas-chromatographisch bestimmt werden kann. Pentandiol dient als innerer Standard. Die mittlere relative Näherungsstandardabweichung des Konzentrationsbereichs von 0,1–15% Äthandiol beträgt ±8,8%.
    Notes: Abstract Ethanediol as a component of formaldehyde-ethanediol polymers is converted into ethanediol diacetate by reaction with a boiling mixture of acetic anhydride and perchloric acid. The ethanediol diacetate is determined by introducing the reaction mixture into the injection port of a gas-chromatograph. Pentanediol serves as an internal standard. The mean relative standard deviation of the concentration range from 0.1 to 15% of ethanediol is ± 8.8%.
