[Effect of different storage times of blood sera on their hormonal activity]. / Vliianie razlichnykh srokov khraneniia syvorotok krovi na ikh gormonal'nuiu aktivnost'.

Hormonal activity of the sera was studied immediately after blood collection and 6 months, one year and 1.5 years following their storage at a temperature of -20 to 25 degrees C in 10 healthy males aged 18 to 20 years. It was found that differently directed changes in immunologic activity of blood serum hormones took place on long-term storage at low temperatures. The data obtained suggest that the adrenocorticotropic hormone, immunoreactive insulin, protein-bound iodine and follicle-stimulating hormone retain the immunologic activity not more than one year, while the hormone, stimulating interstitial cells, thyrotrophic hormone, somatotrophic hormone, 17-HOCS, testosterone and aldosterone up to 1-1.5 years. During this storage of frozen biosubstrates the recurrent freezing out that produces changes in the immunologic activity of some hormones should be excluded.

[Adenohypophyseal hormone and corticosteroid content in the blood and urine in light mechanical injury]. / Soderzhanie nekotorykh gormonov adenogipofiza i kortikosteroidov v krovi i mochi bol'nykh pri legkoi mekhanicheskoi travme.

A considerably increased content of adrenocorticotropic, somatotropic and thyreo-stimulating hormones of the hypophysis in the blood serum, as well as corticosteroids in the blood and especially in the day urine was noted in 27 male patients with the first 4--8 days after light mechanical traumas not resulting in pronounced disturbances of homeostasis and having favourable outcomes. It has been shown that a simultaneous assessment of cortisole and corticosterone in the day urine is most informative among the studied forms of adrenal hormones (17-OCS, cortisole, corticosterone) in the evaluation of the functional state of the adrenal cortex and corticosteroid balance in the organism of the patients.

[Effectiveness of 1 of the specialized devices for mass cardiological screening of the population]. / Ob éffektivnosti odnogo iz spetsializirovannykh ustroistv dlia massovogo kardiologicheskogo obsledovaniia naseleniia.

The efficacy of a specialized device for automatic ECG analysis was appraised on the grounds of examination of 1,499 healthy and sick persons. The method makes it possible to detect 74,2% of patients with diseases of the cardiovascular system. Patients with ischemic heart disease were detected with the greatest reliability (over 90%). A high reproduction of the results on homogeneous contingents of healthy and sick persons is shown, which is evidence that the use of specialized devices for automatic ECG analysis should be recommended for the cardiological screening of the population.

[Changes in the indicators of hormonal activity of the adrenal glands, sympathetic-adrenal system and hemodynamics in healthy persons at different times during the 24-hour period]. / Izmenenie pokazatelei gormonal'noi aktivnosti nadpochechnikov, simpatiko-adrenalovoi sistemy i gemodinamiki u zdorovykh liudei v raznoe vremia sutok.

The following were studied in 24 healthy men aged from 20 to 40 years: circadian rhythm of catecholamines and their precursors production, 17-ketosteroids, 17-oxycorticosteroids, variational pulsometry indices, arterial pressure parameters, resilient-viscous properties of large arterial vessels and arterioles, indices characterizing the mechanical activity of the myocardium. Comparison of the results obtained indicated that, although there existed no complete correlation between these indices, there proved to be a nocturnal tendency to reduction of noradrenaline and dopamine production, to reduction of 17-ketosteroids and 17-oxycorticosteroids, along with rarefaction of cardiac contractions, increased variation in the rhythm, and diminution of arterial pressure and cardiac output parameters. Reverse changes were noted during the day-time.
