pH of the sweat from patients with cystic fibrosis and in controls was measured as a function of the sweat-rate using a fluorescence-pH-indicator (umbelliferone). In both populations sweat is acid at low sweat-rates and alkaline at high ones. The results do not favour an abnormality of the ductal H+-secretion as the pathomechanism of cystic fibrosis.
使用荧光pH指示剂（伞形酮），测量了囊性纤维化患者和对照组汗液的pH值随出汗率的变化情况。在这两组人群中，低出汗率时汗液呈酸性，高出汗率时汗液呈碱性。这些结果不支持将导管H⁺分泌异常作为囊性纤维化的发病机制。
