[Thoracotomy and thoracoscopy in the treatment of patent arterial duct in infants weighing less than 2500 g].

[Iodine metabolism in uranium poisoning according to whole-body radiometry and activation analysis].

Experiments on rats showed that in chronic uranium poisoning the value of the intrathyroid iodine pool changed and time-dependent radioiodine recirculation relationship between the thyroid and the organism was upset. The process of the thyroid adaptation is a complex one, viz. the hormonal capacity of the organism being kept up through an increase in the mass of the thyroid as well as by a higher rate of iodine exchange.
