[Function of the hypothalamus-thyroid system long after radiation and neurotropin correction of the disorders...

In experiments on Wistar male rats exposed to single X-ray radiation 0.5 Gy and combination of X-ray 0.5 Gy and 131I 6.5 microCi/kg inhibition of activity of excitatory and inhibitory neurotransmitter processes in the mediobasal hypothalamus was observed 6 months after radiation. This was accompanied by a prolonged hypofunction of the thyroid gland related to disorders with glandular stromal follicles and secretion of hormones into the bloodstream. Application of neurotropin that normalizes to a certain extent the transmitter relationship in the hypothalamus does not act positively on the thyroid functional activity. All this indicates a necessity of combined correction of the disorders found not only with neurotropic drugs but also with directional therapy of the affected organs and systems.
