Quinidine 29-38 alpha-internexin Cavia porcellus 73-76 10320683-3 1999 RESULTS: Salicylate enhanced quinidine-induced tonic and phasic block of INa at a holding potential of -100 mV but not at a holding potential of -140 mV; this enhancement was accompanied by a shift of the hinfinity curve in the presence of quinidine in a further hyperpolarized direction, although salicylate alone did not affect INa. Quinidine 29-38 alpha-internexin Cavia porcellus 330-333 10320683-3 1999 RESULTS: Salicylate enhanced quinidine-induced tonic and phasic block of INa at a holding potential of -100 mV but not at a holding potential of -140 mV; this enhancement was accompanied by a shift of the hinfinity curve in the presence of quinidine in a further hyperpolarized direction, although salicylate alone did not affect INa. Quinidine 240-249 alpha-internexin Cavia porcellus 73-76 1337728-3 1992 The channel state dependent blocking effects on cardiac sodium current (INa) of quinidine and disopyramide were studied under the whole cell variation of the patch clamp technique. Quinidine 80-89 alpha-internexin Cavia porcellus 72-75 9592721-4 1998 Quinidine (30 microM) and verapamil (0.1 microM) produced use-dependent depression of INa and ICa, respectively. Quinidine 0-9 alpha-internexin Cavia porcellus 86-97 1337728-10 1992 CONCLUSIONS: Quinidine produces more potent tonic and use dependent block of INa by binding to sodium channels at both rested and inactivated states, while disopyramide has a higher affinity for activated state. Quinidine 13-22 alpha-internexin Cavia porcellus 77-80 1658339-1 1991 To determine if the fast sodium current inactivation process is necessary for sodium current (INa) blockade by quinidine, we studied the effects of quinidine on INa in guinea-pig ventricular myocytes treated with chloramine-T, which removes the fast inactivation process of INa. Quinidine 111-120 alpha-internexin Cavia porcellus 94-97 1658339-3 1991 Quinidine (10 microM) produced resting block of INa of 36 +/- 2% (n = 5) at the peak potential of -30 mV in chloramine-T treated myocytes. Quinidine 0-9 alpha-internexin Cavia porcellus 48-51 1658339-4 1991 Quinidine decreased INa in a dose-dependent manner. Quinidine 0-9 alpha-internexin Cavia porcellus 20-23 1658339-7 1991 Even after removal of the fast inactivation process of INa, use-dependent block was observed in the presence of quinidine when various depolarizing pulse durations (5 ms approximately 200 ms) were applied repetitively at intervals of 300 ms approximately 2 s. Longer depolarizing pulses and higher frequency pulse trains produced greater use-dependent block. Quinidine 112-121 alpha-internexin Cavia porcellus 55-58
