TL;DR
It is suggested that these endocrine changes may be mediated by Mo acting at a hypothalamic level to enhance TSH synthesis under certain experimental conditions.
Abstract
The administration of morphine (Mo) to adult male rats resulted in a decrease in body weight, thyroid weight and pituitary-thyroid-stimulating hormone (TSH) content and in increase in pituitary and adrenal weight. Serum TSH and goiter growth on propylthiouracil (PTU) challenge was normal. Stalk-median eminence (SME) TSH content was increased and net TSH synthesis as measured over 24 hr was augmented in Mo-treated rats. It is suggested that these endocrine changes may be mediated by Mo acting at a hypothalamic level to enhance TSH synthesis under certain experimental conditions.
