The Excitatory Mechanism of Substance P in the Antral Circular Muscle of Guinea Pig Stomach
Jun, Jae-Yeoul, Kim, Sung-Joon, Choi, Youn-Baik, Kim, Ki-Whan 대한생리학회 대한생리학회지 10 Pages

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... -
Effects of Lemakalim, a Potassium Channel Opener, on the Contractility and Electrical Activity of the Antral Circular Muscle in Guinea-Pig Stomach

were also measured in single smooth muscle cells and excised membrane patches by using the patch clamp method. Lemakalim induced hyperpolarization and inhibited spontaneous contractions in a dose-dependent manner. These effects were blocked by glibenclamide and low concentrations of tetraethyl ammonium (< mM). Glibenclamide blocked the effect of lemakalim on the membrane potential and slow waves. The mechanoinhibitory effect of lemakalim was blocked by pretreatment with glibenclamide. In a whole... -
Regulatory Action of ß-adrenergic Agonist and 8-bromocyclic AMP on Calcium Currents in the Unfertilized Mouse Eggs

eggs. In this study, the effects of isoprenaline (ISP) and cyclic AMP on calcium influx through calcium channels were investigated to show their relationship with the signal transduction process in unfertilized mouse eggs. Using whole cell voltage clamp techniques, calcium currents, elicited by the depolarizing pulses of 300 ms duration (from -50 mV to 50 mV in 10 mV increments) from a holding potential of -80 mV, were recorded. The current-voltage (I-V) relation of calcium currents was shown to... -
Effect of Cyclic GMP on the Calcium Current in Rabbit Ventricular Myocytes

In order to investigate the effect of intracellular cyclic GMP on calcium current the whole-cell patch clamp technique with internal perfusion method was used in isolated ventricular myocytes of the rabbit. Cyclic GMP, 8-bromo-cyclic GMP, cyclic AMP, isoprenaline and forskolin were perfused into cells and their effects on calcium current were analysed by applying depolarizing step pulses of + 10 mV in amplitude far 300 msec from holding potential of - 40 mV. Not only cyclic AMP (100 μM) but... -
Effect of Dopamine on the Ca2+-dependent K+ currents in Isolated Single Gastric Myocytes of the Guinea-pig

of dopamine on the gastric smooth muscle, the effects of dopamine on voltage-dependent Ca2+ currents and Ca2+ -dependent K+ currents were observed in enzymatically dispersed guinea-pig gastric myocytes using the whole-cell voltage-clamp technique. Experiments were also done using isometric tension recording and conventional intracellular microelectrode techniques. 1) The effect of dopamine on the spontaneous contraction of antral circular muscle strips of the guinea-pig was excitatory in a... -
Effects of Noradrenaline on the Spontaneous Contraction and Ionic Current in the Antral Circular Muscle of Guinea-pig Stomach

in muscle strips and the whole cell patch clamp technique in isolated gastric myocytes. On recording slow waves, noradrenaline (10-5 M) induced the hyperpolarization of the membrane potential, although the shape of the slow waves became tall and steep. Also, spike potentiaIs occurred at the peaks of slow waves. These changes were completely reversed by administration of phentolamine (10-5 M), an α-adrenoceptor blocker. Noradrenaline-induced hyperpolarization was blocked by apamin (10-7 M), a... -
Cl--sensitive Component of Ca2+-activated Tail Current in Rabbit Atrial Myocytes

used the whole cell patch clamp technique to examine the ionic basis for the tail current after depolarizing pulse in single atrial myocytes of the rabbit. We recorded the tail currents during various repolarizations after short depolarizing pulse from a holding potential of -70 mV. The potassium currents were blocked by external 4-aminopyridine and replacement of internal potassium with cesium. The current was reversed to the outward direction above +10 mV. High concentrations of intracellular... -
