Effect of Hormones on Lymphatic Tissue

Abstract
"The material reviewed will be confined to the influence of hormones on the involution and growth of lymphatic tissue and on the structure and number of circulating lymphocytes. The functional significance of hormonally induced acute involution which involves such problems as the role of lymphatic tissue in the synthesis and release of certain serum proteins and also its role in the bodily economy have been recently reviewed elsewhere." The involution of lymphatic tissue is induced by age, gonadal, adrenocortical, and other, hormones, alterations in the external environment, inanition, pregnancy and lactation, and other stresses; and certain chemical agents. The complicated interplay of gonadal, adrenocortical, purified steroid, growth, and thyroid hormones upon the growth of lymphatic tissue are reviewed; also the factors related to decrease and increase of blood lymphocytes, particularly stress and adrenocortical insufficiency.
