The purpose of this study was to measure the effects on mucus clearance after physical exercise. We measured mucociliary clearance at rest and during exercise in eleven patients with mild or moderate bronchial hypersecretion. The subjects inhaled an aerosol containing 99mTc-labelled albumin millimicrospheres. Four sets of scintigraphic images were obtained with 15 minute intervals. The lung retention of radioactivity was quantified using a gamma camera and the clearance of particles from the lungs were calculated for each 15 min period. The first image was obtained directly after inhalation, the second after a period of 15 min rest, the third after a period of exercise on a bicycle ergometer and the final fourth image after another period of rest. We found no differences in the clearance rate at rest and after exercise.
本研究的目的是测量体育锻炼对黏液清除的影响。我们测量了11例轻度或中度支气管分泌亢进患者在静息状态和运动过程中的黏液纤毛清除功能。受试者吸入含有99mTc标记白蛋白毫微球的气雾剂。每隔15分钟获取4组闪烁扫描图像。使用γ相机对肺部放射性滞留进行定量，并计算每15分钟期间肺部颗粒的清除率。第一张图像在吸入后立即获取，第二张在静息15分钟后获取，第三张在自行车测力计上运动一段时间后获取，最后第四张图像在另一段休息时间后获取。我们发现静息状态和运动后的清除率没有差异。
