The possible role of Cl− currents in regulatory volume decrease processes has been explored in HeLa cells using the whole-cell recording mode of the patch-clamp technique. Cells showed very small currents in voltage-clamp experiments performed with Cl−-rich, permeant-cation-free (N-methyl-d-glucamine replacement) intracellular and bathing solutions.(More)
The plasma membrane of locust skeletal muscle contains two types of K+ channel; a maxi, Ca2+-activated 170 pS channel (BK channel) and an inward rectifier of 35 pS conductance (IK channel). The effects of ryanodine, 9, 21-didehydroryanodine and 9, 21-didehydroryanodol on these channels have been investigated. In the concentration domain 10−9 M to 10−5 M,(More)
A study on the influence of procaine on both active and passive transport properties of isolated frog skin, at temperatures ranging between 15 and 25 degrees C and at increasing concentrations up to 2%, was carried out. The active transport of sodium as expressed by the short-circuit current, is inhibited when procaine is added to the solution bathing the(More)
A detailed investigation of the effects of mild glutaraldehyde (GA) treatments on both active and passive transport properties of isolated frog skin is presented. The active transport of sodium, as expressed by the short-circuit current, is gradually inhibited when GA is present in the Ringer solution on the serosal face of the skin, even at 0.01% (w/v)(More)
