Ca2+ current and tension have been simultaneously recorded from single twitch fibres of the semi-tendinosus of Rana esculenta in a medium containing a physiological Ca2+ concentration (1.8 mM). Under appropriate conditions it can be shown that tensio

In previous work on frog atrium [11], we have shown that the carbachol-induced K current (iCCh) and the inward rectifying K channel (iK1) are both inhibited by cesium ions. A more detailed study [1, 2] indicates that the dose-response and the voltage

Toxin gamma from the venom of Tityus serrulatus scorpion produces a partial block of the surface Na+ channel in frog muscle. This block occurs with no change in the voltage-dependence or in the kinetics of the remaining surface Na+ current. The parti

1. The membrane current of frog twitch muscle fibre has been recorded together with contraction in the test gap of a double sucrose gap apparatus. 2. In Ringer, the inward current sometimes shows 2 phases with the same threshold and the same reversal

Simultaneous records in current clamp conditions of potential and of contraction of frog skeletal twitch muscle fibre have shown that a part of the contraction directly depends on the intervention of sodium ions (increase in presence of veratrine, de

In a Ca-free, Mg-free medium containing EGTA (10-3M) auricular trabecles develop a slow inward current which is a pure sodium current. After 12 min in this medium, it is still possible to obtain a phasic mechanical activity which shows a perfect corr

The effect of ethylenediamine derivatives of tetrodotoxin (enTTXI and enTTXII) on frog skeletal muscle was studied both electrophysiologically and biochemically. Electrophysiological experiments with one of these molecules (enTTXI) showed that the co
