1. The effects of metabolic poisoning, intracellular Mg(2+) and pH on ATP-dependent K+ (K+ATP) channels were examined in adult mouse isolated skeletal muscle fibres using the patch clamp technique....
Similarity of ATP-dependent K+ channels in skeletal muscle fibres from normal and mutant mdx mice.
1. ATP-dependent K+ (KATP) channels were studied in fibres isolated from flexor digitorum brevis and interosseal skeletal muscles of normal and mutant mdx mice using the patch clamp technique in the...
Allard, B, Bernengo, J C, Rougier, O, Jacquemond, V
1. Enzymatically isolated skeletal muscle fibres were used to investigate the effects of applying acetylcholine (ACh) onto the endplate area on intracellular free calcium concentration ([Ca2+]i)...
The action of acetylcholine on background conductance in frog atrial trabeculae.
Garnier, D, Nargeot, J, Ojeda, C, Rougier, O
The action of acetylcholine (ACh) on membrane potential and currents in frog atrial muscle has been studied with a double sucrose gap technique. The results show the following. 1. ACh induces the...

Action of heptaminol hydrochloride on contractile properties in frog isolated twitch muscle fibre.
Allard, B., Jacquemond, V., Lemtiri-Chlieh, F., Pourrias, B., Rougier, O.
1. Heptaminol stopped or delayed the progressive decline in tension which characterizes the phenomenon of fatigue in frog isolated twitch muscle fibre. 2. Heptaminol had no action on the sodium,...
Action of cromakalim on potassium membrane conductance in isolated heart myocytes of frog.
Pilsudski, R., Rougier, O., Tourneur, Y.
1. The effects of cromakalim on membrane currents were studied at 20 degrees C in frog atrial and ventricular cells in patch clamp recording using the whole cell configuration. 2. When cromakalim (1...
