title: Differential activating effects of ethanol in C57BL/6Abg and DBA/2Abg mice.
abstract: A characteristic pattern of ETOH-induced locomotor activation in the DBA/2Abg strain (D2), small activation or sedation in the C57BL/6Abg (B6), and an intermediate position of the F1s was found using a between-group design and 1.5 g/kg ETOH. This pattern was consistent for a variety of behavioral indices not previously examined, including distance, rest time, movement speed and length, as well as the traditional horizontal counts. Using a within-subject, multiple day, repeated-testing procedure, the same three genotypes were also assessed after manipulating drug administration order, where ETOH exposure (1.5 g/kg) was on either the first or second test day. Another experiment examined the effect of lighting level on the response to 1.5 g/kg ETOH using a within-subjects approach. Neither the testing order nor lighting condition had any major influence on the magnitude of activation as measured by locomotor activity (distance). The pattern of additive genotypic influences exhibited by the B6, D2, and F1 mice is remarkably resistant to these contextual and procedural manipulations.
