The Role of Anion Exchanger on Pulmonary Vascular Response to Sustained Alveolar Hypoxia in the Isolated Perfused Rabbit Lung
Background: Some respiratory diseases may induce alveolar hypoxia thereby hypoxic pulmonary vasoconstriction (HPV). However, the mechanisms of this physiologic phenomenon are not fully understood. This study was the first to investigate the role of anion exchanger in sustained HPV.Methods: Experiments were performed in the isolated perfused rabbit lung. After preparation, the lungs were divided...
متن کاملPulmonary vascular response of the coati to chronic hypoxia.
The unusually muscular pulmonary arteries normally present in cattle and swine residing at low altitude are associated with a rapid development of severe pulmonary hypertension when those animals are moved to high altitude. Because these species lack collateral ventilation, they appear to have an increased dependence on hypoxic vasoconstriction to maintain normal ventilation-perfusion balance, ...

متن کاملPulmonary vascular response to exercise in the dog.
The effects of exercise on the pulmonary circulation were studied in seven experiments on five dogs. Pulsatile pulmonary arterial flow and pressure and left atrial pressure were measured by chronically implanted transducers; pulmonary vascular input impedance, resistance, and hydraulic power were computed. The average effects of running on a treadmill at 6.5 mph, as compared with the resting st...
