[Comparative analysis of quinolinic acid and L-kynurenine action on the electrically controlled membrane ion channels of mollusk neurons].

Extrasynaptic effects of kynurenines (chynoline acid and L-kynurenin) on the membrane electrosensitive ionic channels were studied in experiments using isolated somata from the c. n. s. of mollusc Lymnaea stagnalis. The kynurenines either blocked or induced biphasic dose-dependent effect on amplitudes of the membrane ionic currents.
