Interaction between Ca²⁺ channel antagonists and carbamazepine on serotonin release. The interaction between 1 μM GVIA, IVA and CBZ on basal, Ca²⁺- and K⁺-evoked hippocampal serotonin releases are represented in a, b and c, respectively. The ordinates indicate the mean±s.d. (n=6) of serotonin release level (fmol sample⁻¹), under the condition of perfusion without or with 100 μM, 1000 μM CBZ. The data was analysed by two-way ANOVA with Tukey's multiple comparison (*: P<0.05; **: P<0.01).
