A hyperpolarization-activated current, Ih, is often implied in pacemaker-like depolarizations during rhythmic oscillatory activity. We describe Ih in the isolated respiratory centre of immature mice (P6-P11). Ih was recorded in 15% (22/146) of all inspiratory neurons examined. The mean half-maximal

Compound YS 035 [NN-bis-(3,4-dimethoxyphenethyl)-N-methylamine] is a new synthetic compound capable of inhibiting Ca2+ uptake by different cells. The inhibition of Ca2+ uptake by muscle cells isolated from chicken embryo is dose-dependent in the compound YS 035 concentration range 10-30 microM.
In isolated guinea-pig papillary muscle ([K+]o: 4.7 mmol/l, stimulation rate: 1 Hz) the verapamil derivative NN-bis-(3,4-dimethoxyphenethyl)-N-methylamine)-HCl (YS035; 0.3-100 mumol/l) increased the action potential duration measured at 90% repolarization level (APD90) up to 132% of control and enhanced the force of

The electrophysiologic mode of action and potency of the verapamil derivative YS 035 (N,N-bis-(3,4-dimethoxyphenethyl)-N-methyl amine) were investigated in sheep cardiac Purkinje fibres. Action potential duration measured at a repolarization level of -60 mV (APD-60) and membrane currents recorded with the
