Effects of etafon on calcium ion contents in smooth muscle cells of the aorta

: Aethaphonium (dialicor) in 5-20 microM concentrations causes the dose dependent Ca decreasing in resting smooth muscle cells of rabbit aorta. In dose of 0.5-2.0 microM dialicor decreases the extent of transient in cytosolic-free calcium induced by application acetylcholine (10 microM) and high extracellular K (119 microM). This effect of dialicor is most expressed in attitude to the myocytes, containing the hyper K medium.
