Intracellular free Ca2+ contributes to regulation of various events occurring in vascular smooth muscle cells. One of these events is modulating the membrane iou currents. Single smooth muscle cells were isolated from rabbit mesenteric artery. Three kinds of Ca2+-activated current were studied with the patch clamp method. Ca2+-activated K+ current with a large oscillation was recorded in the depolarized potential range. The single channel conductance of this current was about 250 pS. It was...

The whole-cell mode 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...

Synthetic potassium channel openers (KCOs) are agents capable of opening K-channels in excitable cells. These agents are known to have their maximal potency in the smooth muscle tissue, especially in the vascular smooth muscle. Much attention has been focused on the type of K-channel that is responsible for mediating the effects of KCOs. As the KCO-induced changes are antagonized by glibenclamide, an KATP (ATP-sensitive K-channel) blocker in the pancreatic β-cell, KATP was suggested to be the...

To study the underlying mechanism through which the endothelium-dependent relaxation is inhibited by blocking the Na+ -K+ pump, the effects of Na+ -K+ pump blockade on the release of EDRF and its relaxing activity were examined, using organ bath study, bioassay technique, and cGMP measurement. Endothelium-dependent relaxation was attenuated by blocking the Na+ -K+ pump in the vascular ring with intact endothelium. In bioassay experiment EDRF release was decreased with the blockade of the Na+...

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...

current, which might reflect the changes of intracellular calcium concentration, was enhanced by dopamine. This effect was abolished by phentolamine. 5) The enhancing effect of dopamine on the Ca2+ -dependent K+ current disappeared with heparin which is known to block the action of InsP3. From these results, it is suggested that dopamine acts via InsP3-mediated Ca2+ mobilization from intracellular stores and such action potentiates the spontaneous contraction of guinea-pig gastric smooth muscle.

Effects of the endothelium on the contractile responses to norepinephrine (NE) were investigated in isolated helical strips of the proximal and distal coronaries artery of pigs. The helical strips were immersed in Tris-buffered Tyrode s solution equilibrated with 100% O2 at 35℃ and its isometric tension was measured. NE relaxed the strips precontracted with acetylcholine from both the proximal and distal coronary artery. NE-induced relaxation, which might be induced mainly by β-adrenoceptor...

In order to elucidate the properties of the background current whole cell patch clamp studies were performed in rabbit ventricular cells. Ramp pulses of ±80 mV from holding potential of 40 mV(or 20 mV) at the speed of 0.8 V/sec were given every 30 sec(or 10 sec) and current-voltage diagrams(I-V curve) were obtained. For the activation of the background current isoprenaline, adenosine 3 ,5 -cyclic monophosphate(dBcAMP), guanosine 3 ,5 -cyclic monophosphate(cGMP), and N6-2 -o-dibutyryladenosine 3...
