Ontogenesis of the kidney in the congenital hypothyroid rat. Biochemical and anatomical parameters of general development.
The effect of congenital thyroid deficiency upon the postnatal development of the rat kidney has been studied by measuring the nucleic acid, protein and lipid contents, and the area and thickness of the different regions in the organ, i.e. cortex, outer and inner medulla. Thyroid deficiency, induced by daily propylthiouracil treatment, strongly affects the development of the renal cortex. The medulla, and still more its inner part which develops early and partly before the onset of thyroid function, is relatively preserved. These effects are completely corrected by daily thyroxine therapy, excluding a possible toxic effect of the antithyroid drug. Moreover, they are partly reversible after cessation of propylthiouracil treatment.
