Gasser R, Horn S, Köppel H Discrimination by valinomycin K-selective surface microelectrodes of a sulphonylurea-sensitive and a distinct sulphonylurea-, barium-, TEA- and cinnamate-insensitive component of K-efflux from isolated pig coronary arteries during simulated ischaemia Journal of Clinical and Basic Cardiology 1998; 1 (1): 43-51 PDF Summary Overview

Figure/Graphic 5: K-Efflux in Koronararterien Measurement of Na+ with Na+ selective microelectrode during simulated ischaemia in an isolated pig coronary artery strip. Na+s did not change throughout the ischaemic episode, indicating a steady state of transmembrane Na+-movement during early simulated ischaemia in this preparation. In the presence of glibenclamide (50 microM), Na+ also remained unchanged. Left and right hand panel from the same preparation. Glibenclamide added 20 minutes before beginning of trace on the right hand panel. Like in Figure 4, left and right hand panel from the same preparation |
