[Assessment of therapeutic efficacy in thromboses of the inferior vena cava by means of colour duplex scanning].

A total of two hundred and twenty-eight 18-to-83-year-old patients diagnosed with thrombotic occlusion of the lower-limb deep veins were examined in order to evaluate the possibilities of colour duplex angioscanning as a method aimed at monitoring both the course of and efficacy of treatment for acute venous thrombosis, as well as at preventing thromboembolic complications. Studied were the localization, incidence rate, and complications of the course of various types of venous thrombosis. It was demonstrated that an uncomplicated course the disease was observed in more than 80% of cases.

[Hygienic assessment of the intake of fish products and their quality].

The impact of provision of the population with fish products and the level of their intake on public health was studied. Analysis of statistical data and the results of the authors' own data has provided strong evidence that the reduction in the volume of catch of water biological resources, the production, and intake of their foodstuffs, as well as the low actual quality of fish products on the consumer market significantly deteriorate the indices of the population's health state.

Ultrasound criteria for embologenicity of venous thrombosis.

Altogether 136 patients aged 17 to 79 years with a diagnosis of acute and subacute thrombosis of lower limb deep veins were examined by duplex scanning in order to derive the ultrasound criteria for embologenicity of inferior vena cava thrombosis. The authors evaluated thrombosis standing (from the emergence of the first clinical signs to its diagnosis), the length and site of the floating portion, the area of the transverse section of the thrombus, the character of the external contour, and the degree of thrombotic mass mobility. It has been established that: along with the generally accepted criteria for floating thrombi there is a number of the echographic characteristics which exert a significant effect on the probability of embolic complications; the degree of thrombotic mass mobility has a material effect on the incidence of thromboembolic complications and may be classified as insignificant, moderate and pronounced while embolic complications are largely present when the mobility of thrombotic masses is moderate or pronounced; the incidence of thromboembolic complications is significantly higher in the presence of a floating thrombus having uneven hypo- and isoechogenic contour and heterogeneous structure.

[Inhibitory effect of antimicrobial preparation from lipids of marine fishes on tissue and microbial enzymes].

We obtained a new food preservative from marine fish lipids possessing pronounced activity in relation to bacteria and microscopic fungi. The effects of this preparation on enzymes of microorganisms and muscle tissue of marine hydrobionts were studied. In vitro the preparation irreversibly inhibited acid and alkaline proteases and proteolytic and lipolytic enzymes of microorganisms and reduced enzyme activity in fish muscle tissue.

[Factors, determining the activity of a new antimicrobial substance from fish oils from various species].

The induction of antimicrobial activity of a new preparation, an aqueous fraction of water-oil emulsion oxidized by air oxygen, was studied. The effect of various factors (the degree of unsaturation of the initial oil and the content of oil oxidation products in obtained preparation) on the antimicrobial activity was determined. The antimicrobial activity of the preparation was induced by oil oxidation.
