Radioactive human serum albumin (RHSA) and urea were injected into the pleural cavity of patients with pleural effusions. The dynamics of the pleural liquid was investigated based on the volume of the pleural liquid and on the change in the concentrations of markers. RHSA concentration in the pleural liquid decreased linearly and slowly. Urea disappeared rapidly and exponentially. The analysis shows that water exchanges rapidly at the pleural capillary and that the volume of the pleural liquid is an affecting factor on the turnover of the pleural volume. The dynamics of malignant effusion was the same as that of tuberculous effusion.
将放射性人血清白蛋白（RHSA）和尿素注入胸腔积液患者的胸腔内。根据胸腔积液的体积和标志物浓度的变化来研究胸腔液体的动态变化。胸腔积液中RHSA浓度呈线性且缓慢下降。尿素迅速呈指数形式消失。分析表明，水在胸腔毛细血管处快速交换，且胸腔积液的体积是影响胸腔容积周转的一个因素。恶性胸腔积液的动态变化与结核性胸腔积液相同。
