We studied the influence of blockers of muscarinic M1, M2, and M3 receptors on the effect of acetylcholine in the myocardial tissue of caval veins in rats at the early stage of ontogeny. The experiments were performed on isolated preparations of the right superior vena cava working under their own rhythm. Action potentials were recorded using the standard microelectrode technique. Acetylcholine (1 μM) suppressed automatic activity in the superior vena cava myocardium. Preliminary perfusion of the preparation with non-selective blocker atropine (1 μM) completely abolished the effect of acetylcholine, treatment with M2 receptor blocker AQ-RA 741 (1 μM) led to partial suppression of the effect of acetylcholine. Blockers of M1 and M3 receptors pirenzepine (1 μM) and 4DAMP (0.1 μM) did not suppress the effect of acetylcholine. Thus, the effect of acetylcholine is predominantly realized via M2 receptors, but M3 receptors can also partially mediate its effect in the superior vena cava myocardium in rats at the early stages of ontogeny.
