cystic fibrosis . sweat osmolality in patients with Fractional measurements of

was studied by vapour pressure osmometry in 24 patients with cystic fibrosis and 24 healthy controls. There was a continuous but proportionate fall in sweat concentrations during the collection period. Mean (SD) initial sweat concentration in the control group was 154-4 (32-6) mmollkg falling, after 50 ,ul of sweat produced, to 92*9 (15-8) mmollkg. In the… (More)
