[Thyroid regeneration in dogs following its resection]

Experiments were conducted on 40 dogs; one lobe of teh thyroid gland or one lobe and 2/3 of the other lobe were removed. There was no gain in weight of the remaining lobe, or of the residue of the gland's lobe. Recovery of the thyroid gland function by hypertrophy of the thyroid epithelium in its remaining portion was achieved by hyperplasia of the intracellular structures.
