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)
Electrical phenomena resulting from transepithelial ion transport have been a subject of clinical, physiological, pharmacologic and toxicologic studies. These examinations concern mainly electric phenomena in live organisms. The changes of transepithelial ion pathways which take place postmortem have not been yet established. The aim of the study was an(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)
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)
INTRODUCTION The aim of this study was to evaluate the influence of hypothyroidism on oxidative modification of low density lipoprotein (LDL). MATERIAL AND METHODS 24 patients with overt hypothyroidism and 10 patients with mild hypothyroidism were enrolled to the study. The control group consisted of 24 healthy subjects with normal serum TSH. Plasma level(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)
OBJECTIVES Toluene diisocyanate (TDI) due to its widespread use in industry is one of the most common and well-known causes of occupational asthma and Reactive Airways Dysfunction Syndrome (RADS). In this study the impact of TDI on the electrophysiological properties of the airways wall, particularly on the mechanisms of absorption of sodium ions and(More)

The transepithelial potential difference and changes of diameter of isolated snail intestine as index of its motility were studied in immersed bath in control conditions and after gentle stimulation by 60 seconds of washing of the intestinal lumen. Immediate depolarization and 20% augmentation of the lumen were observed during the stimulation. After(More)
