title: Behavioural effects of piperonyl butoxide in male mice.
abstract: Piperonyl butoxide was administered to male mice from 5 to 12 weeks of age in the diet at levels of 0 (control), 0.15, 0.30, and 0.60%, and some behavioural parameters were measured. The animals performed three trials in multiple water T-maze at 10 weeks of age, and the number of errors was significantly decreased in treatment groups on the 3rd trial, while there was no biologically significant effect of piperonyl butoxide on maze learning. The motor activity of the exploratory behaviour was measured by ANIMATE AT-420 at 8 and 11 weeks of age. At 8 weeks of age, some parameters were increased in the 0.30% group, while there was no consistent compound- or dose-related effect. At 11 weeks of age, some parameters were different in treatment groups, and there were biologically consistent significant effects; i.e., number of movements, movement time, total distance, average speed, and number of turnings increased. From these results, piperonyl butoxide showed adverse effects on the motor activity of the exploratory behaviour in male mice.
