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...

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 calcium buffer inhibited the activation of the current. Diltiazem and ryanodine blocked it too. These data suggest that the current is activated by intracellular calcium released from sarcoplasmic reticulumn. When the internal chloride concentration was increased, the inward tail...

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 ,5 -cyclic monophosphate(dBcAMP) were applied after all known current systems...

Although the existence of nerve cells which determine the activity of sympathetic nervous system in ventrolateral medulla is advocated recently, there are wide varieties on the location and function of them according to authors. Present study aimed to identify and characterize the medullospinal tract cells in rostral and caudal medulla of cats .which branch to the lateral horn of the upper thoracic spinal cord. Cats were anesthetized with α-chloralose. The upper thoracic spinal cord and floor...

In order to elucidate systematically the effects of serotonin on gastric motility of guinea-pig, the contractile and electrical responses to serotonin were recorded using four kinds of muscle strips prepared from antral circular, antral longitudinal, fundic circular, and fundic longitudinal muscles. Experiments were performed using various methods including isometric contraction recording, transmural electrical field stimulation, junction potential recording, intracellular microelectrode...

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...

The change of the acridine orange absorbance was used to monitor the formation and/or dissipation of a pH gradient in microvillous membrane vesicles (MVV) isolated from human term placenta. Under Na+ efflux conditions, an acidification of the intravesicular space occured and it was completely inhibited by 0.1 mM amiloride. Under K+ efflux conditions, an acidification of the intravesicular space occured and it was potentiated by valinomycin or FCCP. An inwardly directed chloride gradient also...
