Consequences of neonatal combined hormone (oxytocin + TSH) exposure for the adult rat.

Neonatal exposure of rats to oxytocin + TSH damaged the receptor in the same manner as neonatal treatment with high dose of TSH alone. Exposure to oxytocin af adult rats given oxytocin + TSH when newborn depressed hormone reception of a similar degree to TSH, suggesting the possibility of an association between the two receptor sites.
