[Reversible amytal-induced depolarization of perfused rat liver cell membranes].


Prompt, completely reversible and deep (to 75%) depolarisation was obtained in perfused rat liver, treated wih amobarbital sodium to 10 mM. Kinetically the main effect developed in a relatively narrow concentration interval 3-4 mM. Administration of amobarbital in 12-15 mM may produce a progressive reduction of membrane potentials to null and positive… (More)
