single K+ channels of skeletal muscle from the rat and frog were into planar lipid bilayers and their properties were studied. Fusion was induced by an osmotic gradient. Of the four types of K+ channels recorded, the two most frequently observed were a voltage and Ca2+-activated K+ channel and a K+ channel with a prominent conductance substate. The first K+ channel was identified as the large Ca2+-activated K+ (BK) channel because the open-state probability was increased with depolarization...

The contraction of rabbit basilar artery was examined as a function of changes in the Na+ electrochemical gradient in order to determine the contribution of Na+/Ca2+ exchange to the modulation of contractility. Ouabain (10-5 M) or K+-free Tyrode solution caused an increase in tonic tension even in the presence of a Ca2+ channel blocker (10-6 M verapamil) and an α-receptor blocker (10-5 M phentolamine). After treatment with ouabain (10-5 M), contractions were augmented by reduction of external...

The present study was performed to investigate the properties of ionic currents elicited by voltage pulses in the unfertilized eggs of mouse and hamster by using the whole cell voltage clamp techniques and to find out if there are any differences in properties between eggs of the two rodents. In addition, the modulatory effect of G proteins and protein kinase C (PKC) on the ionic channels were observed. The inward current in hamster eggs was shown to be due to Ca2+ current (ica)). The current...

The effects of Cd2+ on spontaneous contraction, and the contractures induced by 0mM Na+, 60mM K+ and 10-6 M acetylcholine, 1mM caffeine were studied in order to elucidate diverse actions of Cd2+ on the Ca2+ mobilization related with contractility in the antral circular muscle of guinea pig stomach. Cd2+ inhibited the spontaneous contraction in a does dependent manner (10-6 M 10-4 M). Cd2+ (3 X 10-5M) suppressed 60 mM K+ induced contracture composed or a phasic and a tonic response and the...

in internal solution). The voltage dependence and the inactivation time course of VDCC in our cells were identical to those of bovine chromaffin cells. A persistent inward current was first activated by depolarizing step pulse from the holding potential (H.P.) of -80 mV to -40 mV, increased to maximum amplitude at around +10 mV, and became smaller with progressively higher depolarizing pulses to reverse at around +60 mV. The inactivation time constant (τ), fitted from the long duration test...

The effects of changes in extracellular Na+ and Ca+ concentration on the membrane potential and contractility were studied in the antral circular muscle of guinea pig stomach in order to elucidate the existence and the nature of Na+/Ca2+ exchange mechanism. All experiments were performed in tris buffered Tyrode solution which was aerated with 100% O2 and kept at 35℃. The treatment of 10-5 ouabain was performed to induce intracellular Na+ loading prior to the start of experiment. The results...

In the rabbit renal artery, mechanisms of contraction by sodium depletion were investigated. The helical strips of isolated renal artery were immersed in the Tris-buffered salt solution. The contractions were recorded isometrically using a strain-gauge transducer. Na-free solution (Na was substituted by Li, choline or sucrose) produced contractions which were dependent on the nature of the Na substitutes. Na-free solution (choline) produced the contraction in ouabain-pretreated artery (Na loaded...

Inactivation properties of Ca current in the unfertilized eggs of mouse were studied by using the whole cell voltage clamp technique and single microelectrode voltage clamp technique. Membrane potential was held at -80 mV and step depolarization was applied from -50 mV to 50 mV for 200 ~ 500 ms. Peak of inward Ca currents was -2 ~ -4 nA at a membrane Potentials from -20 mV to 0 mV and outward currents were not observed within the membrane voltage range studied (-50 ~ 50 mV). Inward currents were...

Single smooth muscle cells of the rabbit pulmonary artery were isolated by treatment with collagenase and elastase. Using the patch clamp technique, potassium channel activity was recorded from the inside-out membrane patch. The channel had a sin히e channel conductance of about 360 pS in symmetrical concentration of K on both sides of the patch, 150 mM, and had a linear current-voltage relationship. During the application of 10 mM tetraethylammonium (TEA) to the intracellular membrane surface,...
