Levothyroxine replacement therapy with vitamin E supplementation prevents the oxidative stress and apoptosis in hippocampus of hypothyroid rats.
OBJECTIVE: To examine the effect of levothyroxine (L-T4), vitamin E or both on oxidative stress status and hippocampal apoptosis in a propylthiouracil (PTU)-induced hypothyroid rat model.
METHODS: Sprague-Dawley rats were randomly divided into five groups: Control, PTU+PTU+L-T4+PTU+Vit E, PTU+Vit E+L-T4. In each .....
