There was a considerable reduction in the body content of organic iodine, suggesting tissue thyroid hormone deficiencies in both the active phases of leprosy and the regression stage. The observed substantial T3 and TSH elevations in the same contingent of patients are likely to be a compensatory and homeostatic response. The anti-leprosy drug dapsone that significantly diminishes permeability of the thyroid tissue-blood barrier to thymidine (an experiment on 20 sexually mature albino rats) is one of the factors aggravating the above deficiency.leprosythyroid hormonesiodine exchangedapsoneлепратиреоидные гормоныйодный обмендапсон[Алешина Б.
