The activity of the pituitary hormones (ACTH, STH, TTH, FSH, LH), the adrenal hormones (cortisol, aldosterone), the kidney hormone (renin), and the thyroid hormones (thyroxine tri-iodthyronine), the thyroxine binding capacity of blood proteins and the activity of the hormones of the pancreas (insulin) and the sex glands (testosterone, estradiol) were studied in 26 males suffering from ischemic heart disease verified by means of selective coronarography and in 20 healthy males with no atherosclerosis of the coronary arteries of the heart. Patients with ischemic heart disease were found to be marked by increased activity in the blood of ACTH, TTH, cortisol, aldosterone, insulin, and estradiol and reduced concentration of STH, thyroxine, and testosterone. These shifts in the activity of the hypothalamo-hypophyseal system and in its subordinate hormonal systems play an important role in the origin of the atherosclerotic process and assosiated ischemic heart disease.

Altogether 16 persons with STH-producing hypophyseal adenoma were investigated by tacho-oscillography, total rheography, blood taken from the ulnar vein, a radioimmunoassay to determine the levels of STH, ACTH, cortisol, deoxycorticosterone, aldosterone, T3, T4, vasopressin, prostaglandin E2, 6-keto-prostaglandin F1 alpha, and plasma renin activity. Acromegalic patients demonstrated an elevated level of STH, and prostaglandin E2 secretion was inhibited. Two groups of patients were singled out according to the hemodynamic state: the 1st group was characterized by a hyperkinetic type of circulation and normotension of borderline hypertension; the 2nd group was characterized by hypokinetic circulation, increased vascular resistance, labile or stable arterial hypertension. The interrelationship of hemodynamic and hormonal indices was unnoticed. It has been assumed that of pathogenetic importance in the development of arterial hypertension is depletion of E2 production, and at early stages--body liquid retention resulting from hypersomatotropinemia.

A complex of investigation was performed in 30 males with newly diagnosed prostatic cancer (stages T2NOMO-T3NO-1MO) before treatment with estrogens, 2-3 months and 1 year after its start. The complex included evaluation of blood lipid spectrum (HDL, LDL, VLDL, triglycerides), hemostasis (coagulation, platelet aggregation, fibrinolysis), hormonal profile (blood hydrocortisone, aldosterone, testosterone, estradiol, STH, FSH, LH, prolactin, plasma renin activity), central and intracardiac hemodynamics, ECG. 66 healthy men of advanced age served control. It was found that estrogen therapy affected blood lipid metabolism, leading to impairment of physiological correlation between HDL and triglycerides, increased blood levels of VLDL and triglycerides. Long-term estrogen treatment brought about enhancement of hemocoagulation and platelet aggregation. Hormonal shifts involved hyperprolactinemia, hypersomatotropism, hypercorticism, aldosterone hypersecretion, proportional androgens-estrogens alterations. Hormonal abnormalities produce side effects in estrogen-treated CHD and hypertonic patients: negative ECG readings indicative of deteriorated coronary circulation and hypertensive episodes, central hemodynamic disorders, respectively. In view of possible cardiovascular damage related to estrogen therapy, a differentiated approach is proposed which would allow a long-term estrogen treatment free of relevant complications.

Thirty-five stage I-II essential hypertension subjects aged 25-63 were examined after the 1st and 10th acupuncture to clarify the effect of a single procedure and a course of acupuncture treatment on blood ACTH, STH, TTH, beta-endorphine, neurotensin, thyroxine, aldosterone, hydrocortisone and plasma renin activity. The hormonal spectrum was determined by radioimmunoassay using special kits. The blood was obtained before acupuncture, 5 min after introduction of the needles, immediately and 30 min after their removal. It is shown that acupuncture-related decline of arterial pressure occurs in participation of pituitary and adrenal hormones as well as polypeptides beta-endorphine and neurotensin.

Data presented in this study suggest existence of hyperendorphinism in uraemic patients. This hyperendorphinism may be regarded both as a primary beneficial compensatory mechanism counteracting disturbances of the internal environment, while causing secondary harmful side effects, which contribute to the uraemic state. Erythropoietin treatment of uraemic, haemodialyzed patients is followed by marked endocrine alterations (suppression of plasma levels of STH, ACTH, prolactin, glucagon, aldosterone, cortisol and plasma renin activity, elevation of plasma insulin and atrial natriuretic levels, lack of influence on plasma PTH, CT and AVP). It remains to be clarified whether the erythropoietin induced endocrine alterations are due to correction of the existing anaemia or reflect a specific effect of this hormone.

Measurements of blood plasma ACTH, hydrocortisone, STH, somatostatin, insulin, glucagon levels and plasma renin activity in 70 patients with borderline hypertension (BAH) and in 20 normal male subjects have revealed increased ACTH, hydrocortisone, and somatostatin levels, elevated plasma renin activity, and reduced STH and insulin levels in the patients. A possible role of the pressor hormone system activation in the pathogenesis of borderline arterial hypertension and in BAH transformation into essential hypertension is discussed.

The results of investigation of the secretion of hypophyseal, adrenal and renal hormones resulting from parlodel administration in 44 patients with Itsenko-Cushing disease were discussed. Concentrations of corticotropin (ACTH), prolactin, somatotropin (STH), thyrotropin (TSH), cortisol, aldosterone, adrenalin, noradrenaline, dopamine and blood renin activity were determined by radioimmunoassays and radioenzymatic methods on an empty stomach and 30, 60 min., 2, 4 and 24 h after parlodel administration (2.5 mg) per os. Parlodel administration in Itsenko-Cushing disease was shown to cause a decrease in the secretion of hypophyseal hormones (ACTH, prolactin and STH). The level of cortisol raised before the start of the investigation was gradually decreased after the drug administration and reached its minimum in 2-4 h. Correlation of the basal level of aldosterone and blood renin activity, and a response of the renin-angiotensin-aldosterone system to parlodel administration was revealed. Changes in the secretion of catecholamines were of diverse nature: a decrease in the blood concentration of noradrenaline in the absence of adrenalin and dopamine shifts.

In the first experimental series, 10 healthy male test subjects with a high susceptibility to motion sickness showed a significant increase of ACTH, cortisol, STH, prolactin, ADH, aldosterone concentrations, and plasma renin activity after vestibular tests. The 10 subjects with a moderate susceptibility exhibited a still higher increase of the hormones, except plasma renin. The 8 test subjects with a low susceptibility displayed a considerable increase in ACTH, cortisol, and STH after vestibular stimulation. In the second experimental series, the increase of STH, cortisol, ADH, aldosterone and renin occurred immediately after rotation in the moderate susceptibility subjects and an hour after exposure in the high susceptibility subjects. This may be indicative of specific immediate adaptation mechanisms or excitation transfer in the CNS in high susceptibility persons. In the third experimental animal series, the permeability of the blood-brain barrier for 125I and IgG increased after rotation. Greater concentrations of potassium, chloride, and urea in CSF are suggestive of an inhibition process activation in the CNS and, probably, of an active urea transport by the vascular plexus epithelium which maintains constant osmotic pressure of cerebral extracellular fluid and prevents hyper-hydration of CNS neurons.

Cortisol, insulin, somatotropin, thyreotropin, thyroxine, triiodothyronine, testosterone, aldosterone, c-AMP, c-GMP, prostaglandins (PGF1-x, PGF2-x, PGA + E), and renin concentrations in serum or plasma of the venous blood of the third international crew of the scientific orbital complex of "Soyuz 29 - Salyut 6 - Soyuz 31" were determined following the 7-day space flight. The increased activity of the renin-angiotensin-aldosterone system before the flight as well as variations in the pressor/depressor prostaglandin ratios indicate an increased strain during the pre-flight period. During the first stage of the post-flight period some parameters were changed due to the landing process and the returning to earth gravity. The associated physical load and the onset of reactions for enhancement of the orthostatic tolerance resulted in an increase of cyclic nucleotid and thyroxine concentrations. The relatively higher levels of the pressor PGs of group F in comparison with the prostaglandins A + E could be evaluated as a compensatory reaction for enhancement of the orthostatic tolerance. The cortisol and STH concentrations increased with growing motor activity. The variations seen after the 7-day space flight were essentially within the reference areas. It may be assumed that the readaptation was not yet totally accomplished by the 8th day after landing.
