THYROID-FUNCTION IN BRAIN CONCUSSION

RIA was used to study the quantitative content in the blood serum of t hyrotropic (TTH), thyroid (total thyroxine (T4), free thyroxine, triio dothyronine (T3) hormones and thyroxine-binding capacity of blood plas ma proteins in 30 patients with brain concussion from the first to the 12th day of disease. The patients' hormonal profile was characterized by normal characteristics of TTH, depression of the transport organic phase of thyroid metabolism with a decrease of the T4 concentration, a reduction of the thyroxine-binding capacity of plasma protein, and s imultaneous activation of the peripheral stage of iodine metabolism wi th excess accumulation in the blood of active hormones - free thyroxin e and T3. The data obtained deepen our understanding of the pathogenes is of craniocerebral injury (CCI). The neuroendocrine syndrome identif ied is specific for mild CCI. It can be used as a differential diagnos tic criterion for expert medical evaluation purposes.
