    Description / Table of Contents: Zusammenfassung Die bronchokonstriktorische Reaktion von ACH-Aerosolen ist in niedrigeren Konzentrationsbereichen bei Hunden abhängig von der Körperlage. Bis zu einer Maximalreaktion sind die Anstiege der Strömungswiderstände in Seitenlage der Tiere trotz gleichen Atemminutenvolumens immer größer als in Rückenlage. Entsprechende Konzentrationskurven werden mitgeteilt. Die arteriellen Blutgase, Herzfrequenz und Druck in der A. femoralis wurden ebenfalls gemessen. Die von der Körperlage abhängige unterschiedliche bronchokonstriktorische Reaktion wird auf die vorwiegend unilaterale Ventilation der Tiere in Seitenlage zurückgeführt.
    Notes: Summary The bronchomotoric reaction following ACH-aerosol in low concentrations is dependend on the position of the body on dogs. Up till one maximal reaction the increase of the airway resistance is always stronger in the lateral position. Nevertheless the breathing minute volume is constant. Concentration reaction curves will be shown. Arterial blood gases, heart rate, and pressure in the arteria femoralis were also measured. The different strongness of the reaction following ACH-inhalation will be caused by the predominantely unilateral ventilation of the animals in the lateral position.

    Description / Table of Contents: Zusammenfassung Mikrokristallines Glucocorticoid (9α-Fluor-16α, 17α-isopropyliden-dioxyprednisolon) wurde Fibroblastenkulturen zur Phagocytose angeboten. Versuchskulturen wurden mit dem Medium nach FIDP-Phagocytose sowie mit glucocorticoidhaltigem zellfreien Nährmedium über 6 Wochen beschickt. Die Versuchsergebnisse zeigen: Mikrokristallines Glucocorticoid wird von Phagocyten aufgenommen. Es verursacht in den Fibroblasten den typischen Glucocorticoidstoffwechsel mit Bremsung aller gemessenen Parameter: Sauerstoffverbrauch, Glucoseverbrauch, Milchsäure- und Brenztraubensäureentstehung, Zellwachstum und Mitoserate. Auch die typischen morphologischen Veränderungen werden ausgelöst. Glucocorticoid penetriert durch die Zellmembran in das Umgebungsmedium. Dieses Medium bewirkt an Versuchskulturen die gleichen typischen Stoffwechsel- wie morphologischen Veränderungen. Diese Veränderungen lassen für mikrokristallines Glucocorticoid die Deutung zu, daß dieses phagocytiert wird. Das intracellulär in Lösung gehende Glucocorticoid ruft an diesen Zellen typische Glucocorticoidwirkungen hervor. Genügend Substanz gelangt durch die Zellmembran in die Extracellulärflüssigkeit, um von dort aus systemische Wirkungen zu ermöglichen.
    Notes: Summary Microcrystalline glucocorticoid (9α-fluor-16α, 17α-isopropylidene-dioxyprednisolon) has been offered to fibroblast cultures for phagocytosis. Test cultures have been supplied with the medium after FIDP-phagocytosis as well as with cell-free nutrient medium containing glucocorticoid for 6 weeks. Test results show: microcrystalline glucocorticoid is taken up via phagocytes. It causes within the fibroblasts typical glucocorticoid metabolism with inhibition of all parameters measured: oxygen-consumption, glucose-consumption, formation of lactic and pyruvic acids, cell-growth and mitosis rate. Also the typical morphological changes are provoked. Glucocorticoid penetrates through the cell-lining into the environmental medium. This medium produces on test cultures the same typical metabolic and morphological alterations. These alterations allow the interpretation as regards microcrystalline glucocorticoid that it is phagocytable. Glucocorticoid dissolving intracellularly provokes in these cells typical glucocorticoid effects. There is sufficient substance left to pass through the cell-lining into the extracellular fluid to allow systemic effects from there.

    Notes: Zusammenfassung Die Bestimmung der verschiedenen Totraumgrößen bei Patienten mit obstruktivem Lungenemphysem gibt die Möglichkeit, die Ursachen für die Vergrößerung des funktionellen Totraumes zu erfassen. Der „absolute Totraum“ ist bei diesen Patienten nur mäßig vergrößert. Die Vergrößerung des „Mischluftanteiles“ und die Entwicklung von „Paralleltoträumen“ wird diskutiert. Als im Vordergrund stehend wird die ungleichmäßige Ventilierbarkeit des Alveolarraumes angesehen, die alle „funktionellen Symptome“, wie sie bei obstruktivem Lungenemphysem zu beobachten sind, einschließlich des reversiblen arterio-venösen Kurzschlusses erklären kann. Die nach der Bohrschen Formel zu errechnende Vergrößerung des funktionellen Totraumes entspricht nicht der Vergrößerung von Toträumen im anatomischen Sinne. Die Vergrößerung des funktionellen Totraumes ist ebenfalls aus der ungleichmäßigen Ventilation mit dem Auftreten von alveolär-arteriellen Kohlensäuredruckgradienten abzuleiten.

    Notes: Summary The homozygote deficit of alpha1 antitrypsin (alpha1 PI-ZZ) in patients frequently results in a premature development of emphysema in the lung due to incomplete protection against proteases. An active inhibitor substitution appears to be useful. The presented study proves the biological effect of alpha1 antitrypsin infused into 8 patients. The results were an activity increase of leukocyte elastase and trypsin inhibition in serum as well as doubling of alpha1 antitrypsin in sputum. This therapeutical conception (with a dose of 60 mg/kg body weight/week) results in an efficient protection. Inhibitors specific for mucosa are not influenced. An improvement of lung function during 6 weeks of intravenous therapy was not achieved. The progressive destruction of lung parenchyma can be probably prevented, however.

    Notes: Summary Previous investigations have demonstrated high histamine concentrations in the sputum of patients with chronic obstructive airway disease (COAD). A possible histamine generation by bacteria has been discussed. In the present work, histamine concentrations in native and incubated sputum of patients with COAD were determined. Histamine was assayed fluorimetrically after separation by HPLC. Histamine concentration in native sputum amounted to 10–1140 ng/ml. After 72 h incubation at 37° C 100–20700 ng/ml histamine was detected. A mean 26-fold increase in histamine content was observed. Heating of the sputum almost completely prevented the rise in histamine concentration during incubation. The same effect was achieved by adding an antibiotic to the sputum before incubation. Histamine content in sputum of patients with COAD decreased considerably after therapy with the antibiotic doxycycline. Histamine formation by bacteria may account considerably for the histamine concentration in sputum of patients with COAD.
