Background: Previous animal studies have shown that intragastric administration of water can accelerate mesenteric lymph flow. Similarly, human studies have shown that abdominal breathing can induce thoracic lymph drainage. In these studies, lymph flow was measured by hemodilution and a corresponding reduction in blood anti-diuretic hormone (ADH) levels, the latter being linked to urine osmolarity. Hence, we questioned if induction of lymph flow through water administration and supine positioning could be measured by monitoring urine osmolarity.

使用人类参与者的尿液渗透压评估通过胸导管的淋巴流量。

背景：以前的动物研究表明，灌胃水可以加速肠系膜淋巴流动。同样，人体研究表明，腹式呼吸可以诱发胸腔淋巴引流。在这些研究中，淋巴流量是通过血液稀释和血液抗利尿激素 (ADH) 水平的相应降低来测量的，后者与尿液渗透压有关。因此，我们质疑是否可以通过监测尿液渗透压来测量通过饮水和仰卧位诱导淋巴流动。
