The effects of capsaicin, dimethyl sulphoxide and pH changes on transport of sodium and/or chlorine ions in an isolated frog skin, were studied using electrophysiological methods, adapted to evaluation of ionic currents occurring in the epithelial tissues and organs. The experiment consisted in measuring potential difference (PD in mV) of an isolated skin of the aquatic frog, Rana esculenta L., placed in a Ussing apparatus. The ionic transport processes were modified through incubation of the tissue in Ringer solution and in Ringer solution supplemented with amiloride, bumetanide, and also with dimethyl sulphoxide. The direct effect of capsaicin and dimethyl sulphoxide (DMSO) on frog skin was assessed while these compounds were added to the Ussing chamber with a pipette and a peristaltic pump. Adaptive reactions of the tissue were assessed following at least 60-min exposure to those compounds. It has been demonstrated that amiloride-inhibited sodium ion transport and acidification of the incubation medium (pH 6.4) inhibited mechanically induced epithelium reactions. Both compounds, capsaicin and DMSO modified ionic transport processes depending on the mechanical stimulation.
