[Hormonal disorders in borderline arterial hypertension].

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.

[Functional status of the endocrine system in patients with hypertrophic cardiomyopathy].

The study was undertaken to examine 27 patients aged 20 to 50 years who had hypertrophic cardiomyopathy (HC). Group 1 consisted of 12 patients with asymmetric cardiomyopathy. Group 2 comprised 15 with symmetric cardiomyopathy. Blood samples were taken from the cubital vein before and 30 and 60 minutes after administration of 0.2 mg thyroid-releasing hormone (TRH). Blood hormone concentrations were measured by radioimmunoassay. TRH test was found to provide an essential information on the function of the hypothalamo-hypophyseal-thyroid and hypothalamohypophyseal-adrenal systems in HC patients. The HC patients showed lower function of the hypothalamo-hypophyseal-adrenal system. There was a decrease in serum testosterone during all the periods of examination. At the same time the patients from Groups 1 and 2 had substantial features of the function of various links of the immune system, which may suggest a variance in the pathogenesis of the two types of the disease.

[Functional state of the hypothalamo-hypophyseal-gonadal system in patients with chronic alcoholic intoxication].

The function of the hypothalamo-pituitary-gonadal system has been studied in 118 males with different stages of alcoholism. Comparison with the control group has shown decreased levels of interstitial cell stimulating hormone (ICSH), follicle-stimulating hormone (FSH), and testosterone, and elevated concentrations of prolactin (Prl). Differences in the parameters of hormonal activity expressed in a varying degree of a decrease in FSH, ICSH, and testosterone, and a Prl elevation are related to change in mutual regulatory influences between the gonads and hypothalamo-pituitary complex. The most informative parameters were concentrations of Prl and testosterone (considering elevation in the former and reduction in the latter hormone) and the ratio of their concentrations. Difference of these parameters in each group (corresponding to the stages of alcoholism) may be used as an additional diagnostic criterion of chronic alcohol intoxication.
