The functional morphology of the hypothalamic neurohypophyseal system (HNHS) and juxtaglomerular apparatus (JGA) were studied in 50 male cats. A rising secretory activity in HNHS and JGA, accompanied by accumulation of hormone-containing granules, was seen in acute vascular insufficiency caused by the injection of a ganglion-blocking agent and by bloodletting. This factor is a specific sign of hypotonic stress, consisting in incomplete use of HNHS and JGA adaptive capacity in acute pressor hormone deficit.
