| Abstract: | It is shown that the activity of enzymes participating in renin-angiotensin and brain kinin systems' metabolism depends on functional state of hypothalamo-pituitary-adrenocortical system. Under experimental hypocorticism the activity of angiotensin-converting enzyme and kininase I in the hypothalamus, hippocamp, corpus striatum and rat pituitary decreases; the renin-like enzyme activity decreases in the corpus striatum but increases in the hypothalamus and hippocamp. After hydrocortisone administration to adrenalectomized rats the angiotensin-converting enzyme activity of the hippocamp and pituitary is shown to be normalized as well as renin-like enzyme and kininase I of the hippocamp and corpus striatum. The activity of the studied enzymes in the hypothalamus decreases in this case. |
