    Description / Table of Contents: Zusammenfassung Die Gehirne von Tieren aus 4 verschieden alten Würfen junger Katzen wurden teils lebensfrisch durch Perfusion, teils nach 24 Std durch Immersion fixiert und für Vergleichsuntersuchungen in Paraffin eingebettet. Bei Betrachtung der Gliazellen des Corpus callosum ergab sich: 1. Nach Perfusionsfixierung sind die Kerne der Gliazellen groß und elliptisch. Sie sind wasserklar und haben eine scharf gezeichnete Chromatinstruktur. Nach Immersionsfixierung 24 Std p.m. sind die Kerne dagegen klein und rund, homogen dunkel gefärbt und haben ein kaum zu erkennendes Chromatingerüst. 2. Nach Perfusionsfixierung sieht man im Balken der ganz jungen Tiere zahlreiche Mitosen. Sie fehlen bei den durch Immersion fixierten Geschwistertieren desselben Wurfes. 3. Die nach verschiedener Fixierung beobachteten Unterschiede in der Form der Gliazellkerne werden durch Messungen der Quer- und Längsachsen erfaßt.
    Notes: Summary In four litters of young cats, some of the brains were fixed by perfusion and the others by immersion. The material was embedded in paraffin and the neuroglia was investigated in sections through the corpus callosum. It was found that: 1. After fixation by perfusion the nuclei of the glia cells are large and elliptic. The caryoplasm is clear and there is a distinct structure of the chromatin. After fixation by immersion the nuclei of the same cells are small and round. The caryoplasm is dense and the structure of the chromatin is not clearly visible. 2. After fixation by perfusion mitotic figures are present. They are absent in the brains fixed by immersion. 3. Following different fixation, there are differences in the shape of the nuclei of the glial cells. These differences have been investigated in detail by measuring the diameters of the nuclei.

    Description / Table of Contents: Zusammenfassung Es wird über die Verteilung der Haptoglobinphaenotypen 1–1, 2–1 und 2–2 bei Patienten mit Lebercirrhose (n=174) berichtet und ein Vergleich mit der Hp-Verteilung in einem Normalkollektiv (n=194) angestellt. Dabei ergibt sich bei Patienten mit Lebercirrhose für das Hp 1–1 mit 32% ein signifikantes Überwiegen (p〈0,00025) gegenüber der Normalverteilung bei gesunden Probanden, die für Hp 1–1 mit 14% angegeben ist. Die Wahrscheinlichkeit, an einer Lebercirrhose zu erkranken, ist danach für Träger des Hp 1–1 um den Faktor 4,3 größer als für Menschen mit dem Hp 2–2.
    Notes: Summary The distribution of haptoglobin phenotypes (Hp) 1–1, 2–1 and 2–2 in 174 patients suffering from liver cirrhosis was determined and compared with a reference group consisting of 194 healthy subjects. The study revealed a high frequency of the Hp 1–1 phenotype (32%) in the patients as compared with the control group (14%). This difference is statistically highly significant (p〈0.00025). It was calculated that in individuals of type Hp 1–1, the risk of liver cirrhosis is 4.3-fold higher than in persons with the phenotype Hp 2–2.

    Evaluation of plasmids in tetracycline resistant strains of Neisseria Gonorrhoeae and Ureaplasma Urealyticum in a case of severe urethritis (1985)

    Notes: Abstract A young man who acquired gonococcal urethritis in the Far East was not cured by repeated i.v. treatment with a broad-spectrum penicillin. Cultures of pre- and post-treatment urethral specimens grew tetracycline-resistant penicillinase-producing Neisseria gonorrhoeae (PPNG) and tetracycline-resistant Ureaplasma urealyticum. The patient was successfully treated with erythromycin, to which both isolates were sensitive. The strain of N. gonorrhoeae carried a novel plasmid of 10.5 Md molecular mass in addition to plasmids previously observed in this organism. The strain of U. urealyticum carried two distinct plasmids, one with mass 4.9 Md and the other one with mass 8.1 Md. This report demonstrates that ureaplasmas can contain plasmids and raises the question if tetracycline resistance is controlled by plasmids or by the chromosome.
