Research Abstract |
The neurotoxic effects of tributyltin(TBT) on the F1 rats were examined. The pregnant rats were exposed to TBT via their food, therefore, the F1 rats were exposed to TBT via the placenta and their dam's milk. After weaning, the half of F1 rats were exposed to TBT via their food. The inhibitory effects of behaviors in the F1 rats exposed to TBT via the placenta and their dam's milk were observed as well as the decrease in their body weight compared to the control. The F1 rats exposed to TBT via their food after weaning(at 3 weeks of age) also showed lower activities and body weight compared to the control. The exposure to TBT just after the weaning is toxic as the exposure via the placenta and their dam's milk. The inhibitory effects on the behaviors by TBT may be related to dopamine metabolism, since tyrosine hydorxylase, dopamine transporter and dopamine receptor D2 in the midbrain were down-regulated.
