Bidirectional transport of Na+ and Cl- ions by the epithelium controls production and composition of airway surface liquid and airway transepithelial potential difference and in these ways supports mucociliary transport. Volatile anesthetics are able to inhibit epithelial ion transport processes when applied at high concentration and have been suggested to(More)
Volatile anesthetics are suggested to elicit depression of airway clearance. The involvement of changes in transepithelial ion transport in this inhibition has already been observed. The Ussing method was used to study the changes in mechanical stimulation evoked electrogenic ion transport in isolated rabbit tracheal wall in the presence of halothane and(More)
The study was performed to check if the well-known intestinal spasmolytic effect of mebeverine is paralleled by any changes in intestinal transepithelial currents. The transepithelial potential difference related to ionic currents of the isolated rabbit distal colon wall was measured by means of Ussing's technique under control conditions and after gentle(More)
During the adhesive locomotion of land snails a series of short dark transverse bands, called pedal or foot waves, is visible ifa moving snail's ventral surface is observed through a sheet of glass. Moreover, the mucus secreted from the pedal glands and some pedal epithelial cells forms a thin layer which acts as a glue augmenting adherence, while also(More)
An important electrophysiological variable--the transepithelial potential difference reflects the electrogenic transepithelial ion currents, which are produced and modified by ion transport processes in polarized cells of epithelium. These processes result from coordinated function of transporters in apical and basolateral cell membranes and have been(More)

Unmyelinated C-fibers endings lye beneath the epithelial layer and release neuropeptides which regulate baseline transepithelial potential difference (PD) and changes of transepithelial potential difference during mechanical stimulation (dPD). Ambroxol can suppress reflexes such as the cough or the corneal reflex which are connected to stimulation of C(More)
The influence of UV radiation on electrophysiological parameters of isolated frog skin mounted in Ussing apparatus was studied with the aim to determine the local physiological regulatory mechanisms involved. The studies were performed on isolated ventral frog skin (Rana esculenta L.). Baseline transepithelial electrical potential difference (PD), changes(More)
