current (IK1). Using whole cell patch clamp technique we applied voltage ramp from 80 mV to 140 mV at a holding potential of 30 mV and recorded the whole cell current in single ventricular myocytes isolated from the rabbit heart. The current-voltage relationship showed N-shape (a large inward current and little outward current with a negative slope) which is a characteristic of IK1. Application of 0.2 mM dinitrophenol (DNP, an uncoupler of oxidative phosphorylation as a tool... -

Purkinje cells using immunocytochemical staining technique with anti-calbindin after recording. Spontaneously active cells displayed two patterns of firing, repetitive and burst firings. Two thirds of dissociated Purkinje cells displayed repetitive firing and the rest of them did burst firing under same recording condition. Repetitive firing activities were maintained even after further isolation using either physical or pharmacological techniques. Neither high magnessium solution nor excitatory... -
Calcium Current in the Unfertilized Egg of the Hamster

specific channel was examined in the unfertilized hamster egg using the whole-cell voltage clamp technique. Pure inward current was isolated using a Ca2+-rich pipette solution containing 10 mM TEA. This current was independent of external Na+ and was highly sensitive to the Ca2+ concentration in the bathing solution, indicating that the inward current is carried by Ca2+. The maximal amplitude was -4.12±0.58nA (n=12) with 10mM Ca2+ at -3OmV from a holding potential of -8OmV. This current reached... -

in the antral circular muscle, using isometric contraction recording, conventional microelectrode method and whole-cell patch clamp technique. Substance P produced tonic and phasic contractions in a dose-dependent manner and depolarized membrane potential with increased amplitude of slow waves in muscle strips. Voltage-dependent Ca2+ currents were increased by the application of Substance P from a holding potential of -60mV to 50mV in 10mV steps and this effect was blocked by the addition of an...
