Effects of catecholamines and their inhibitors on the electrical activity of the smooth muscle of the guinea-pig stomach were studied by using pressure electrodes. The spontaneous electrical activity of antrum and corpus preparations consisted of slow waves with or without superimposed spikes. In quiescent fundus preparations, the spike activity and slow waves were generated by TEA. Catecholamines (noradrenaline, isoprenaline and adrenaline) suppressed or blocked the spike discharges and the… CONTINUE READING
