Morphological Changes in the Thymus of Newborn Rats Exposed to Endocrine Disruptor Dichlorodiphenyltrichloroethane (DDT) during the Prenatal Period

The structure of the thymus in newborn rats exposedin utero to endocrine disruptor DDT was studied. We found that exposure to low doses of DDT during pregnancy does not disturb thymus formation in the offspring, but leads to changes in its structure than manifested as slower lobulation, wider epithelium-free areas in the cortex, and lower number of thymic corpuscles in the medulla. The results attest to sensitivity of the reticuloepithelial stroma of the thymus to the effects of endocrine disruptor.
