This paper reports on an effective method for depolymerization of fucoidan in an aqueous medium using ultrasonic treatment. To assess the effect of this treatment, high-molecular-weight fucoidan was dispersed at a concentration of 10 mg/ml in deionized water and subjected to ultrasound at a frequency of 20 kHz with varying intensity. The effect of high-intensity low-frequency ultrasound on the particle size of sulfated polysaccharides isolated from brown algae, where the minimum value of the average hydrodynamic diameter was 85.92 ± 32.9 nm, was studied. The dependence of the particle size of the polysaccharide on the intensity of ultrasonic exposure was revealed. The influence of this effect on the degree of sulfation of fucoidan has been determined. Shown the cavitation activity in the processing environment and discussed the reasons for its change

The article presents results of a study on the effectiveness of using lowfrequency ultrasound and photochromotherapy in the complex treatment of patients with chronic bacterial and viral rhinosinusitis. The study involved 69 people aged 18 to 55 years: 39 (56.83 %) women and 30 (45.11 %) men with chronic rhinosinusitis during the period of clinical exacerbation and concomitant chronic tonsillitis without exacerbation. All patients included in the study underwent X-ray examination or computed tomography and magnetic resonance imaging of the paranasal sinuses. 100 % of the patients were examined for the presence of antibodies to Human gammaherpesvirus 4 (ELISA), had study of blood serum for IgM and IgG and test to determine the avidity of Ig G antibodies to γ-herpesviruses. The obtained data indicate the effectiveness of including low-frequency ultrasound and photochromotherapy in the complex treatment of patients with chronic rhinosinusitis and concomitant chronic tonsillitis of bacterial and viral nature without exacerbation.
