[Thyroid gland activity and motor activity during dog ontogenesis].
The locomotor activity (LA) and the level of the protein-bound iodine (PBI) in the blood serum were investigated in 62 puppies at the age of 1--12 months. A parallel elevation of PBI and the LA was observed the first 4 months after birth. The second peak of the LA at the age of 7--9 months was not accompanied by any PBI rise. Inhibition of the thyroid function with mercasolyl increased the LA at the age of 1--3 months and decreased it at the age of 7 months. An increase of the LA one month after thyroidectomy was found at the age of 1 and 3.5 months. The activity of puppies operated on at the age of one month showed a sharp fall after 2--4 months. The data on various effect of thyroid hormones on puppies of different age pointed to the complex relation between the LA and the thyroid gland function.
