[Thyroid development and morphofunctional state in the postnatal ontogeny of rats with cervical sympathetic ganglia removed].
It has been demonstrated that bilateral extirpation of the cervical sympathetic ganglia in newborn rats results in the enlargement of perivascular connective tissue of the thyroid, as well as in degenerative changes in thyrocytes, desquamation of the latter in the follicular cavity and the increase in the number of large "light" cells. Unilateral extirpation of the cervical sympathetic ganglia usually is not accompanied by changes in the follicular structure of the gland. The enlargement of the connective tissue and changes in the blood vessels are more significant at the side of the operation, whereas the decreased in the height of the thyrocytes is similar in both lobes of the thyroid. Retardation in the development of the thyroid ant the decrease in its functional activity result, evidently, not only from direct denervation of the thyroid, but from changes in the level of regulation of the latter by higher autonomic centres of the brain as well.
