title: [Effect of adrenaline on the influx of Na+ and Cl- in trout (Salmo gairdneri) adapted to seawater].
abstract: The effects of adrenaline on the Na+ and Cl- influxes in the seawater adapted trout were studied with the perfused isolated head technique. With 10(-5) M adrenaline in the perfusion fluid, the lamellar influx of Na+ is increased by 60%, while the Cl- influx is inhibited by 90%. This catecholamine does not modify the extra-lamellar entry of NaCl which passes into the filamental sinus.
