The purpose of the study was to comparatively analyze the parameters characterizing the donor activity of young donors. Anonymous questionnaire survey was made among 427 donors aged 18-24 years. A high proportion of the respondents take part in blood donation due to altruistic motives. Unfortunately, most respondents consider the donor's status is not prestigious due to the inadequate effective social publicity of donation. Donors' low awareness of a blood donating procedure and donation support measures result in no purpose popularization of donor movement. The performed study revealed that a large number of respondents noted the insufficiently convenient working day time schedule of hemotransfusion stations and that most donors expressed their wishes to reduce the time of stay in a donor center. To eliminate the negative influence of the above factors on donors' activity, it is necessary to create comfortable conditions in blood donation centers, by using the positive foreign experience.

To study the causes of dizziness in patients with arterial hypertension (AH), duplex scanning of vertebral arteries (VA) was made in 256 male and female patients aged 31-67 years with grades 1-2 AH and in 56 healthy individuals matched for age and sex. The investigators compared the indicators of 3 groups of patients: 1) those without complaints of dizziness; 2) those with complaints of dizziness episodes; and 3) those with dizziness during its exacerbations. The study established that more than half of the patients had substantial deviations in the readings of VA duplex scanning. In patients with dizziness, on their exacerbation in particular, there was an increase in the diameter of VAs with a significant reduction in the diameter of the right VA and a rise in that of the left one. There was a considerable decrease in right VA blood flow and an increase in left VA one. The authors conclude that among the AH patients with complaints of dizziness, their cause is vertebrogenic spasm of the right VA in more cases. In another, smaller part of patients with AH, the cause of dizziness seems to be dyscirculatory encephalopathy. It is concluded that VA duplex scanning in patients with AH, by using the criteria proposed by the authors is a simple and available tool for the differential diagnosis of these conditions.

The paper presents the experience in treating 1926 patients with acute varicose thrombophlebitis (AVTP) of the lower extremities (the results of the past 15 years of the clinic's work) during massive admission of patients with lower extremity AVTP to the general surgery hospital in the past 5 years. The patients with AVTP are characterized; their basic treatment modalities are given depending on the site, pattern, and duration of a thrombotic process. The unified clinicodiagnostic algorithm for treatment is proposed. The clinic has long given preference to active surgical tactics in the treatment of patients with this pathology. Most patients (n = 1390) underwent surgical intervention that differed in volume and duration. Examining the early and late results of treating patients with AVTP indicated the advantages and disadvantages of some treatment modalities and provided evidence to the benefits of radical treatment.

Blood pressure variations were studied in neonatal infants born to mothers with arterial hypertension by 24-hour monitoring. The trend and stability of blood pressure changes were established in babies, depending on their mothers' health status.

The impact of antiatherogenic diet fortified with phytosterols and amaranth oil on clinical and biochemical parameters was in patients with cardiovascular diseases. The study indicated that fortification of antiatherogenic diet with phytosterols and amaranth oil in patients with coronary heart disease and hypertensive disease contributed to clinical improvement and better anthropometric indicators and blood lipid spectrum. It was concluded that the use of these plant components is highly promising for therapeutic and prophylactic purposes.
