[Functional morphology of the rat thyroid during the first months of the pubertal period]

Morphofunctional parameters of the rat thyroid gland, at the light optic and electron microscopic levels, during first months of the pubertal period are not stable. Quantitative values of these parameters fluctuate with a period of 32-36 days. Some morphofunctional parameters, such as diameter of the thyrocyte nucleus and content of albumine-binding iodine in blood, depend on the animal's body mass, other parameters do not depend on it.
