Nasal potential difference: between the 'sensing' electrode in contact with the nasal epithelium, and the 'reference' electrode, a butterfly needle inserted under the skin of the forearm, is measured. Phloridzin in Ringer's solution will then be additionally perfused onto the nasal epithelium and any further change in nasal PD recorded. On a second visit a repeat of the above protocol will be carried out with phloridzin followed be amiloride.
