The aim of this study was to investigate the role of sympathetic nerve and adrenal gland in the changes in hemodynamics and hypoxic pulmonary vasoconstriction (HPV) induced by cigarette smoking in Wistar rats. Data showed that an increment of pulmonary vascular resistance (PVR) induced by alveolar hypoxia was partially prevented by prazosin (α1-receptor(More)
Durch am Schweinchen durchgeführte Versuche wurde nachgewiesen, daß die akute alveoläre Hypox ie starke pulmonale Vasokonstriktion mit Erhöhung des Herzzeitvolumens hervorrufen kann. Die pulmonale vasokonstriktive Reaktion auf akute alveoläre Hypoxie wurde durch den Lipoxygenase-Inhibitor Diäthylkarbamazin nicht gehemmt, aber durch den(More)
In this study, porcine pulmonary artery segments (intact or denuded) and bronchial segments (with or without epithelium) were tested in organ bath. Hypoxia caused a bronchial epithelium dependent relaxation of intact or denuded pulmonary artery preconstricted with phenylephrine. Constriction in intact pulmorary artery coated with epithelium denuded bronchus(More)
The alteration in hypoxic pulmonary vasoconstriction (HPV) induced by cigarette smoking was studied in Wistar rats, piglets and in humans. The percentage change of pulmonary vascular resistance (δPVR%) and the amplitude of the systolic wave in impedance pneumorheogram (δH%) were used to estimate the strength of HPV. It was observed that immediately after(More)
