[Clinical testing of hygienic criteria for assessing working conditions].

Occupational morbidity in railway transport is discussed. The rates of occupational morbidity are compared with that due to temporary working incapacity. There were no direct correlations between the incidence of major nosological entities of occupational diseases, the magnitude and rate of influence of industrial factors, which provides evidence for their further testing and correction.

[Age-dependent thymus involution in experimental iodine deficiency].

The experiment on white Wistar rats provided morphometric and morphofunctional evidence on correlations between the thyroid and thymus in health and thyroid transformation in iodine deficiency. In chronic iodine deficiency the rate and volume of thymic physiological involution increase. Total shrinkage of the parenchyma of cortical and core substances of thymic lobules from juvenile animals reaches 25% in the experimental group vs 11% in the reference group. The absolute mass of the organ was stable due to increased volume of connective tissue of the interlobular septa and intralobular perivascular spaces. Iodine-dependent thyroid transformation brings about profound changes in correlations between tissue components and cellular subpopulations of the thymic lobule indicating disturbed mechanisms of immunological regulation in iodine deficiency.
