FIG. 9.

The GABA_A receptor antagonist diazepam ameliorates spasms but not body axis curvature induced by developmental deltamethrin exposure. Animals were exposed to 25 μg/l deltamethrin beginning at 3 hpf. Animals were dosed with diazepam at 72 hpf and reobserved 2 h after dosing. Significant differences (p < 0.001) are indicated by asterisks. Diazepam had no significant effect on the incidence of body axis curvature at any of the doses tested. Each experiment comprised 20–25 fish per treatment group, and each experiment was repeated at least three times.
