The efficacy of apitoxin (bee venom; BV) in ameliorating propionic acid (PPA) -induced neurobehavioral impacts was studied. Sixty rat pups were enrolled in a split litter design to six groups: a control group, a PPA-treated group, a BV-treated group, a BV/PPA protective group, a PPA/BV therapeutic group, and a BV/PPA/BV protective and therapeutic group. Exploratory, social, locomotor, and repetitive/stereotype-like activities were assessed and prosocial, empathy, and acquired behavior were evaluated. Levels of neurotransmitter including serotonin, dopamine, and gamma-aminobutyric acid (GABA) were determined and a quantitative analysis of Reelin gene expression was performed. PPA treatment induced several behavioral alterations, as reduced exploratory activity and social behaviors, increased repetitive/stereotypic behaviors, and hyperactivity. In addition, a marked decline of neurotransmitters and down-regulation of Reelin mRNA expression were observed. BV exhibited high efficiency in ameliorating the PPA-induced neurobehavioral alterations, particularly when applied both before and after PPA administration. Overall, the results implied that BV has merit as a candidate therapeutic treatment to alleviate PPA-induced neurobehavioral disorders.
