RESUMO
As evidenced by animal experiments (Wistar rats), the iodophore iodine of the commercial product Jodonal-M is bound by the thyroid gland, if administered with the drinking water. When drinking water containing 2 mg/l iodophore iodine was given, the thyroid glands of the experimental animals bound 1.19%; and those of the control animals, 4.68% 131I. When drinking water containing 1 mg/l iodophore iodine was administered, the thyroid glands of the experimental animals bound 1.90%; and those of the control animals, 6.77% 131I. It is concluded that the iodophore iodine which passes over to the milk during teat disinfection is bound by the thyroid glands in a similar manner and takes part in the formation of the thyroid hormones just as the "native" iodine of the milk.
