Here, we investigated the effects of nicotine on spatial memory in ApoE-knockout (ApoE-KO) and wild-type (WT) mice in a radial arm maze. Training occurred on three consecutive days and the test was performed on day 4, with one trial per day. Then on day 4, animals were administered nicotine (0.1, 0.25, 0.5, and 1.0 mg/kg) or the antagonist of nicotinic(More)
Aldehyde dehydrogenase 2 deficiency may directly contribute to excess acetaldehyde (AcH) accumulation after ethanol (EtOH) drinking and AcH mediates some of the behavioral effects of EtOH. Apolipoprotein E has been suggested to be involved in the alteration of attention and memory. We have chosen Aldh2-knockout (Aldh2-KO), ApoE-KO, and their wild-type (WT)(More)
