The number of rearings (Fig. 2C) was lower in rats administered ethanol at 0.0 g/kg during the fifth 5-min period relative to the first.
Animals receiving the 0.5 g/kg dose reared less during the last 5-min period. Compared to the respective first 5 min, animals administered ethanol at 1.0 g/kg and 1.5 g/kg, respectively, performed significantly fewer rearings from the second 5-min period and onward. Significant between-group differences were found from the first time period (Fig. 2C). Animals administered the 1.5 g/kg dose performed significantly fewer rearings compared to the 0.0 g/kg and 0.5 g/kg doses at all time periods and during the first to fourth time periods compared to the 1.0 g/kg dose.
Animals administered ethanol at 1.0 g/kg had a lower number of rearings compared to the 0.0 g/kg dose from the second time period and onward, and at the second, third, and fifth time period compared to
the 0.5 g/kg dose.
