title: [The effect of leu-enkephalin and its synthetic analog on the behavior of rats with different sensitivities to ethanol].
abstract: Leu-enkephalin and its analogue N 171 increased the pain thresholds and reduced the affective aggression in unrestrained male rats. The N 171 manifested a greater analgesic and antiaggresiogenic effect, particularly in i.p. administration. Preliminary administration of peptides manifested a more obvious effect in alcohol-preferring rats under painful stress.
