Cardiohemodynamics and variability of heart rhythm at rest and at local cold influence in individuals with different initial types of vegetative regulation are studied. The obtained results indicate that young men with a predominance of parasympathetic orientation in the heart rhythm regulation demonstrate high stability of autonomic regulation to the presented cold test, which was manifested by the absence of statistically significant shifts in all studied cardiorhythm indicators and may indicate the cold resistance of this contingent

The specific features of urgent adaptations of a number of functional systems of the body in response to a cycle-ergometric test were under study, and marker criteria for assessing the level of exercise tolerance were identified. Based on the study of heart rate variability, indirect calorimetry, capillary blood flow and a modified PWC170 test, a comparative study was carried out on young men aged 17-19 who were students from among Caucasians born in the North in the 1st and 2nd generations. The results of the study made it possible to establish that the most important and informative indices reflecting the degree of tolerance to the load are the heart rate, the concentration of carbon dioxide in the exhaled air, the oxygen utilization factor, and the rate of capillary blood flow. During the performance of the stress test, such criteria are heart rate, MxDMn in relation to heart rate, reflecting the degree of decrease in parasympathetic activation, as well as the level of oxygen consumption, whose values in individuals with normal load resistance continue to increase until the end of the test.

The study was conducted with aim to assess the effect of clinical and laboratory parameters and JAK2V617F mutation on the incidence of thrombotic complications in patients with classical Ph-negative chronic myeloproliferative diseases. JAK2V617F mutation was detected in patients with polycythemia vera, essential thrombocythemia and patients with primary myelofibrosis. Thrombotic complications were significantly more often observed in carriers of the JAK2V617F mutation and in patients with cardiovascular risk factors

The paper presents results of study of red blood cells (RBC) morphology of deceased from various causes (injury, hypothermia) by using scanning electron microscopy. The obtained data show that the appearance of certain forms of cadaveric erythrocytes depends on the causes of death. Therefore, when death is caused by stabbing and gunshots RBC take acanthocyte forms and in cases of fatal hypothermia - echinocyte forms. In vitro experiment at small negative temperatures the appearance of acanthocytes in blood samples is observed. Based on the obtained data and on the ability of echinocyte to return to normal form, it can be concluded that the probability of restoring the vital activity of the frozen organisms are possible.

In order to achieve high sports results, a comprehensive study of the athlete’s body is necessary.The morphofunctional study is the most informative and accessible. However, the somatotype-related functionalstate of the cardiovascular system of athletes remains insufficiently studied. The purpose of the research: Todetermine the indicators of the cardiovascular system of athletes in response to physical exertion, dependingon the somatotype according to Reese-Eysenck. An anthropometric and functional study of the cardiovascularsystem of 49 athletes of the highest sports skill engaged in freestyle wrestling at the Sakha Republic’s Center forTraditional Sports was conducted. The Reese-Eysenck index was used to determine the somatotype. Functionalexamination of the cardiovascular system included blood pressure measurement and pulse counting at rest, then 1and 2 minutes after exercise. The exercise consisted of a full squat with arms outstretched with a frequency of 20squats in 30 seconds. In order to determine the tolerance of physical activity, the Roufier index was calculated. Theadaptive potential of the cardiovascular system is determined using the index of functional changes. Somatotypingby the Reese-Eysenck index among the examined athletes revealed that a significantly large proportion of theexamined individuals had an athletic somatotype. In pyknics, significantly large indicators of body weight and thetransverse diameter of the chest were recorded. A functional examination of the cardiovascular system with theuse of physical activity revealed a significantly greater increase in systolic blood pressure after 1 and 2 minutesand heart rate 1 minute after physical activity in individuals with the pyknic somatotype compared with others.The analysis of the results of the index of functional changes of athletes depending on the somatotype revealedthe stress of the cardiovascular system function only in athletes of the pyknic somatotype. The obtained resultsindicate that the training process should be selected individually, taking into account the somatotype of an athlete,since among pyknics there are people with stress of the cardiovascular system with good results of physicalactivity tolerance according to the Roufier index.
