of the patch clamp technique was used to study Ca2+-activated Cl- current (IClCa) in gastric antral myocytes. Extracellular application of caffeine evoked Ca2+-activated current. In order to isolate the chloride current from background current, all known systems were blocked with specific blockers. The current-voltage relationship of caffeine-induced current showed outward rectification and it reversed at around ECl-. The shift of reversal potential upon the alteration of external and internal... -

mechanism 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... -
Effects of Noradrenaline on the Spontaneous Contraction and Ionic Current in the Antral Circular Muscle of Guinea-pig Stomach

in guinea-pig antral circular muscle. To investigate the mechanism of this excitatory action, slow waves and membrane currents were recorded using conventional microelectrode techniques 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.... -

using a perforated patch-clamp in ICR mice. In gramicidin perforated patch-clamp mode, KRG extract (KRGE) induced repeatable depolarization followed by hyperpolarization of PVN neurons. The KRGE-induced responses were concentration- dependent and persisted in the presence of tetrodotoxin, a voltage sensitive Na channel blocker. The KRGE-induced responses were suppressed by 6-cyano-7-nitroquinoxaline-2,3-dione (10 μM), a non-N-methyl-D-aspartate (NMDA) glutamate receptor antagonist, but not by... -
Inhibition of voltage-dependent K+ current in rabbit coronary arterial smooth muscle cells by the class Ic antiarrhythmic drug propafenone

In this study, we demonstrated the inhibitory effect of the Class Ic antiarrhythmic agent propafenone on voltage-dependent K+ (Kv) channels using freshly isolated coronary artery smooth muscle cells from rabbits. The Kv current amplitude was progressively inhibited by propafenone in a dose-dependent manner, with an apparent IC50 value of 5.04±1.05 μM and a Hill coefficient of 0.78±0.06. The application of propafenone had no significant effect on the steady-state activation and inactivation... -

Plasma membrane hyperpolarization associated with activation of Ca2+-activated K+ channels plays an important role in sperm capacitation during fertilization. Although Slo3 (slowpoke homologue 3), together with the auxiliary γ2- subunit, LRRC52 (leucine-rich-repeat–containing 52), is known to mediate the pHsensitive, sperm-specific K+ current KSper in mice, the molecular identity of this channel in human sperm remains controversial. In this study, we tested the classical BKCa activators,...
