    Description / Table of Contents: Abstract In a partially ordered ring, a set of iterative methods is constructed in order to approximate the inverse of a given element, not necessarily positive or inverse-positive. Two sequences are generated both converging to the inverse. In addition the inverse is monotonously enclosed. The method of order four has the maximal efficiency index.
    Notes: Zusammenfassung Anknüpfend an Arbeiten von G. Alefeld und J. Herzberger und von J. W. Schmidt werden in einem halbgeordneten RingR Iterationsverfahren untersucht, welche geeignet sind, die Inverse eines nicht notwendig positiven oder inverspositiven Elementesa∈R zu approximieren. Es werden jeweils zwei Folgen (X n ) und (y n ) konstruiert, welche beide gegen die Inversea −1 konvergieren und diese zusätzlich im Sinne vonX n−1 ≦X n ≦a −1 ≦y n ≦y n−1 monoton einschließen. Von den betrachteten Verfahren hat das vierter Ordnung den größten Effektivitätsindex.

    Description / Table of Contents: ZusammenfaBung Bei 21836 Routinesektionen der Jahrgänge 1955–1974 fanden wir in 2469 Fällen multiple oder solitäre Lungenarterienthromboembolien (LAE) (11 %). Männer (1310 Fälle) und Frauen (1159 Fälle) sind etwa gleich häufig betroffen. Der Häufigkeitsgipfel liegt für beide Geschlechter um das 60. Lebensjahr. Etwa 25 % aller LAE sind sogenannte chronische LAE. Die Alters- und Geschlechtsverteilung entspricht derjenigen aller LAE. Frische sowie chronische LAE zeigen eine steigende Tendenz, während tödliche LAE anscheinend seltener werden. Beides deuten wir als Therapieeffekte.
    Notes: Summary In 21,836 routine sections during the period 1955 to 1974, we found multiple or solitary pulmonary thromboembolisms in 2469 cases (11%). Men (1310 cases) and women (1159 cases) are equally affected. The peak age for both sexes is ca. 60. Approx. 25 % are chronic and also occur with equal frequency in men and women in their sixties. Acute and chronic pulmonary thromboembolisms are more common in recent years, whereas fatal pulmonary thromboembolisms seem to be diminishing. Both situations are aBumed to be a result of therapy.

    A Cu(I) ion conductor obtained by replacement of Ag(I) in α-AgI (1976)

    Notes: Abstract A solid conductor for Cu(I) was obtained by introducing Cu(I) into the high temperature form of AgI. The cationic transport number is practically one with negligible electronic conduction. The formula of the compound may be expressed by Ag(1−x)Cu x I withx varying with the temperature.

    Tetanus toxin induced actions on spinal Renshaw cells and Ia-inhibitory interneurones during development of local tetanus in the cat (1977)

    Notes: Summary In anaesthetized cats the activities of Renshaw cells (RCs) and Ia-inhibitory interneurones (IaINs) were recorded during the accumulation of tetanus toxin in the spinal cord following injection into the gastrocnemius muscle. The early response of the RCs increased during the period of development of local tetanus. With some cells there was a subsequent decrease in the early response in later periods of the observation time (16–44 hrs after intramuscular injection). The effects on the spontaneous activity of the RCs were in good correspondence to those on the early response. The hyperactivity of the RCs is proposed to be mediated mainly via disinhibited cholinergic gamma-motoneurones using muscarinic postsynaptic receptors. The “pause” which follows the early response and the recurrent inhibition of IaINs was not reduced during the development of local tetanus. These results indicate that the central action of tetanus toxin in local tetanus does not consist of a general loss of postsynaptic inhibition. It is suggested that tetanus toxin acts mainly on synaptic elements of the alpha- and gamma-motoneurones or on presynaptic nerve terminals in their vicinity. In later periods a disturbing influence on the cholinergic transmission at Renshaw cells seems to occur.

    Proline endopeptidase and exopeptidase activity in polymorphonuclear granulocytes (1976)

    Notes: Summary Peptidases capable of releasing proline residues from polypeptides are present in the cytoplasmic fraction of rabbit polymorphonuclear granulocytes. This was shown with peptide substrates where proline is present either at the carboxy-terminal or within the polypeptide chain. Lysosomal and plasma membrane enzymes were inactive towards such polypeptides. The proline residue was hydrolyzed at either its amino end or its carboxy end. It is noteworthy that a Pro:Pro bond was cleaved both in the pentapeptide Thr-Lys-Pro-Pro-Arg and the dipeptide Pro:Pro.
