Effect of amphetamine and cocaine on seizure in lead treated mice

TLDR: Lead administration from conception through testing increased the probability and duration of transcorneally induced electroconvulsive seizures of 21 day old mice within all three genotypes, and both cocaine and amphetamine injections 15 min prior to ECS reduced the number of animals exhibiting seizures as well as the duration of seizures in both lead treated and control mice.

Abstract: Mice, genetically selected for differences in brain weight were employed Lead administration (05% lead acetate) from conception increased the proportion of 21 day old mice exhibiting seizures; total duration of observed seizures was also increased Mice from the low brain weight line more frequently exhibited seizures than either mice from the high brain weight line or the Binghamton heterogenous stock Although genome and lead administration alter bodyweight, the inability of bodyweight to predict seizure occurence and/or total duration of seizure within conditions also ws noted Lead administration from conception through testing increased the probability and duration of transcorneally induced electroconvulsive seizures of 21 day old mice within all three genotypes, and both cocaine and amphetamine injections 15 min prior to ECS reduced the number of animals exhibiting seizures as well as the duration of seizures in both lead treated and control mice
