    Notes: [Auszug] IN previous communications1 it has been shown that copper sulphide, activated by oxidizing a part of its surface into copper sulphate, is a catalyst for the low molecular polymerization of isobutene. It has now been found that the main product of the catalytic process is a ...

    Notes: Summary Fibrosis and neoplasia are evoked by asbestos fibres. Different experimental models have been used to elucidate the cellular mechanism of their pathogenesis but there is no report available dealing with the role of structural glycoproteins and collagens in the development of the fibrosis. The omentums of 20 female SPF-Sprague-Dawley rats were investigated 1, 2 and 6 months after intraperitoneal injection of 15 mg UICC reference samples of crocidolite, by light- and immunofluorescence microscopy. Using monospecific antibodies, laminin, collagens types I and III and fibronectin were localized. After 6 months typical asbestos bodies were detected. By indirect marking of the basal lamina with anti-laminin-antibodies the marked degree of vessel proliferation occurring during the development of granuloma became visible. The deposition of connective tissue which was already established after 4 weeks was mainly due to collagen type III. After 4 and 8 weeks an accumulation of fibronectin associated with larger asbestos fibres was observed. The results suggest that fibrogenesis is promoted by the opsonic activity of fibronectin for long asbestos fibres. The fibrosis may derive from activated resident fibroblasts.

    Description / Table of Contents: Zusammenfassung Durch Exposition hoher SO2-Konzentrationen wurde an Hunden versucht, eine chronisch obstruktive Bronchitis zu entwickeln. Die Hunde wurden über 175 Tage zwischen 300 und 500 ppm SO2 für insgesamt 435 Std exponiert. Keines der Tiere entwickelte eine schwere Schädigung des Respirationsorgans. Anfänglich stärker erscheinende Symptome klangen bei weiterer Exposition allmählich ab. Die histologische Untersuchung ergab einen erhöhten Besatz mit Becherzellen in der Trachea, in den Haupt- und Lappenbronchien. Auch wurden geringe Veränderungen in den Bronchialdrüsen gefunden.
    Notes: Summary It has been tried in this study to produce chronic obstructive bronchitis in dogs by exposing them to high concentrations of SO2. The study was extended to 175 days and during that period the animals were exposed to 300–500 ppm SO2 for a total of 435 h. None of the three dogs developed serious respiratory damage. Most of the symptoms were transitory. Histological examinations showed increased number of goblet cells in trachea, main- and lobar bronchi and a slight alteration of the bronchial glands.

    Description / Table of Contents: Zusammenfassung Der Einfluß der bilateralen Durchtrennung der Nn. laryngici cranialis, laryngici caudalis und Glossopharyngici auf die durch ACH und Allergen auslösbare Bronchokonstriktion wurde an 15 Hunden untersucht. Bei 3 Tieren wurden lediglich bilateral die Nn. laryngici cranialis freipräpariert als Kontrollreihe. Partielle Durchtrennung des linken Lungenvagus wurde bei 3 Hunden ausgeführt. Die Ergebnisse wurden verglichen mit der radikalen Durchtrennung des linken N. vagus in Hilushöhe ebenfalls bei 3 Tieren. Die Durchtrennung des N. laryngicus cranialis wie die des N.glossopharyngicus führte zu einer Blockierung des allergen-induzierten Bronchospasmus. Die Bronchokonstriktion, die durch ACH auslösbar ist, wurde nicht beeinflußt. Die allergen-induzierte Bronchokonstriktion war aber 3 Wochen nach der Durchtrennung der entsprechenden Nerven wieder nachweisbar. Partielle einseitige Durchtrennung des N. vagus im Lungenhilus brachte einen geringen Abfall der allergen- und acetylcholin-induzierbaren Bronchokonstriktion. Vollständige Durchtrennung des Nerven an einem Hilus verringerte die durch ACH wie durch Allergen auslösbare Bronchokonstriktion signifikant.
    Notes: Summary The influence of bilateral transection of the nervi laryngici cranialis, laryngici caudalis and glossopharyngici on ACH and allergeninduced bronchoconstriction was tested in 15 dogs. In three dogs the free preparation of bilateral nervi laryngici cranialis was performed for control measurements. Partial transection of pulmonary left nervus vagus was performed in three dogs and compared to radical transection of the same nerve in three animals. Transection of the nervi laryngici cranialis as well as of the nervi glossopharyngici was followed by the inhibition of the allergen-induced bronchoconstriction. The bronchoconstriction following ACH challenge was not influenced by transection. Bronchoconstriction induced by allergen returned to the same values within three weeks after surgical intervention. Partial unilateral dissection of the vagus nerve on lung hilus shows a small decrease in bronchial constriction induced by allergen and by ACH. Complete unilateral dissection of the vagus nerve on the lung hilus reduced the bronchial constrictoric response to both substances significantly.
