[Secretion of neurohypophyseal hormones following partial exclusion of peripheral reflex connections].

Influence of complete transversal section of spinal cord on secretion of hormones by hypothalamo-hypophyseal system under adaptive restoration of hyrosecretory function of kidneys was studied in chronic experiments on 28 dogs. In separate terms after the operation the level of antidiuretic hormones and oxytocin in blood plasma did not correspond to degree of organism's hydration--in contrast to intact animals. The mechanism of reciprocal secretion of hormones into the blood and CSF after the spinal section became disordered. The blood--brain barrier remained impenetrable for hormones of neurohypophysis in conditions of the spinal trauma.
