We have reported that dopamine potentiates spontaneous contractions dose-dependently in guinea-pig antral circular muscle strips (Hwang et al, 1991). To clarify the underlying excitatory 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...

increased voltage-dependent Ca2+ currents in the whole range of test potentials. Noradrenaline also increased Ca2+ -dependent K+ currents, and this effects was abolished by apamin. These results suggest that the increase in amplitude and the generation of spike potentials on slow waves was caused by the activation of voltage-dependent Ca2+ channel via adrenoceptors, and hyperpolarization of the membrane potential was mediated by activation of apamin-sensitive Ca2+ -dependent K+ channels.

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...

Permissive action of thyroid hormone at the level of Ca channel and responsible mechanisms underlying thyroid hormone-induced change in myocardial contractile state and T3-induced arrhythmias were investigated in rabbit ventricular or atrial myocytes using whole cell patch clamp technique. Single cells were isolated by Langendorff perfusion with collagenase. Cardiac myocytes were incubated in low-Cl-,, high-K+ medium containing 1μM L-triiodothyronine (T3) at 4℃ for 2.10 hours. The calcium...

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...

고양이 회장 종주근에서 세포막 소포를 분리하여 Na+의 농도 경사에 의존하여 일어나는 Ca2+ 이동의 특성에 대하여 연구하였다. 막소포 내부에서 외부로 향하는 Na+의 농도 경사 존재시 Ca2+의 축적이 현저히 증가하여 Na+ 의존성 Ca2+ 축적을 보였으며, 이는 외부용액에 Na+ ionophore인 monensin을 처리시 소실되었다. 한편 이러한 Ca2+ 축적의 증가 작용은 Na+에 특이적이었으며 K+, Li+, Rb+, Cs+ 및 choline이온은 Na+의 작용을 대치하지 못하였다. Ba2+, Sr2+, Mn2+ 및 Cd2+ 등의 2가 양이온들은 0.5 mM의 농도에서 Na+ 의존성 Ca2+...
