    Notizen: Abstract 1. Respiration rates of broad-bean (Vicia faba) mitochondria were studied as a function of temperature. Arrhenius plots of all membrane-bound enzymes, as obtained with saturating substrate concentrations, revealed a break in the lower temperature range. That break was considered to indicate a phase transition of membrane phospholipids, characteristic for chilling-sensitive plants. A second discontinuity at 30°C occurred only with activities linked to energy conservation. — 2. The activation energies for the oxidation of NAD+-linked substrates differ between states 3 and 4. State 3 respiration of NAD+-linked substrates is the result a superimposition of two branches of electron transport, which can be separated by different sensibilities to rotenone. A characteristic temperature dependency of the respiratory control, as well as a shift of the low temperature break in the Arrhenius plot toward a higher temperature after state 4 to state 3 transition, are calculated to be caused by the superimposition of the two branches. — 3. The temperature dependency of the oxidation of extra-mitochondrial NADH and of succinate differs remarkably from that of the oxidation of matrix-NADH. It has been concluded that the rotenone-resistant oxidation of matrix-NADH and the oxidation of external NADH are mediated via different pathways with individual regulation sites.

    Notizen: Abstract Mitochondria from Vicia faba L. exhibit two pathways for the oxidation of endogenous NADH. One pathway is rotenone-sensitive and includes three phosphorylation sites, the other one is rotenone-insensitive and by-passes site I. This by-pass is located in the area of flavoproteins, but several lines of evidence suggest that the rotenone-insensitive oxidation of matrix-NADH is not mediated by the external NADH dehydrogenase. With saturating substrate concentrations the two pathways are superimposed in state 3 while in state 4 the electrons are transferred only via the by-pass. The rotenone-resistant electron flux is obviously regulated from the substrate side. We suggest that the function of the by-pass is to regulate the NADH/NAD+ ratio of the matrix space.

    Beschreibung / Inhaltsverzeichnis: Summary Collagen types I, II and III from man and calf are distinctly different with respect to their effect on the induction of the aggregation of human platelets. Collagen type III was found to be a particularly potent inducer of platelet aggregation. The pathogenetic implications of these observations are briefly discussed.
    Notizen: Zusammenfassung Die Kollagentypen I, II and III von Mensch und Kalb weisen in löslicher und strukturierter Form deutliche Unterschiede in ihrer Wirkung auf die Aggregation menschlicher Thrombocyten auf. Eine besonders stark aggregierende Wirkung wurde für das Typ III Kollagen gefunden. Die pathogenetische Bedeutung dieses Befundes wird kurz diskutiert.
