Effect of 10 nmol/L vecuronium and 1, 3, and 6 mmol/L magnesium sulphate (MgSO4) alone and in combination on acetylcholine-induced (10 μmol/L) inward currents mediated by adult muscle-type acetylcholine receptor. Horizontal bars indicate drug applications. MgSO4, vecuronium, and the combination of both drugs were pre-applied for 60 s before co-application with 10 μmol/L acetylcholine. After each drug application, a 10 μmol/L acetylcholine-induced inward current was obtained as a control (last control not shown).
