A, time course of recovery for tadpoles following anesthetic equilibration and (left) sham treatment or (right) UVA exposure. 3 μm propofol (open symbols; left structure in right panel) or 4 μm AziPm (closed symbols; right structure in right panel) was used. Treatment times were 3 min (diamonds), 10 min (circles), or 20 min (triangles), and the water was changed at time 0. Data shown is the mean ± S.E. from 3–4 experiments per group. B, in vivo photolabeling for 10 min after equilibration with a sub-EC99 dose of 3 μm AziPm increased the immobile fraction of tadpoles. The water was changed at time 0, with photolabeling from −10 to 0 min. A one-way ANOVA found a significant difference between the three means (p < 0.01), and Bonferroni's post hoc test found a significant decrease in the percentage of mobile tadpoles after lamp exposure and water change (blue bar, p < 0.01). Data represent the mean ± S.E. from three experiments per treatment (± UVA). After equilibration, the tadpoles were randomly assigned to sham or UVA treatment, with the data at −10 min representing both groups and with sham-treated animals represented by the black bar. C, induction and recovery of tadpoles treated with (left) 2 μm propofol or (right) 0.8 μm propofol 20 h after the indicated treatments. Error bars represent S.E.
