1. The action of catecholamines on the transport and the distribution of Na and K and the resting membrane potential (E(M)) has been investigated in soleus muscles isolated from fed rats.2. In a substrate-free Krebs-Ringer bicarbonate buffer adrenaline (ADR) (6 x 10(-6)M) increased (22)Na efflux by 83%, (42)K influx by 34%, and E(M) by 10%. Similar effects were exerted by noradrenaline (NA), phenylephrine, salbutamol and isoprenaline. The effects of ADR on Na-K transport and E(M) were… CONTINUE READING
