[The hormonal regulation of thymus activity in threatened abortion].

It is stated that in women with the abortion threat at any term of gestation (I, II, III trimesters) the endocrine function of the thymus essentially increases. The role of hormones in the thymic activity disorder is studied. It is shown that insufficiency of the functional activity of the trophoblast ranks first in the mechanism of hormonal regulation of thymic endocrine function in nonbearing of pregnancy. The other significant reason of an essential increase in the titer of thymic serum factor (TFS) is a disorder in interconnections inside the hypophyseal-adrenal system. Determination of TFS and the above hormonal indices can be used as the prognostic test of the pregnancy course.
