[The effect of food products with an elevated radionuclide level on the blood and urine indices in rats]. / Vplyv produktiv kharchuvannia z pidvyshchenym rivnem radionuklidiv na deiaki pokaznyky krovi ta sechi shchuriv.

Food influence, including raw meat with radionuclides (6.66 x 10(3) - 20.72 x 10(3) Bq/kg) during 30 days, on some homeostasis values was studied in white not pedigree rats. Erythrocyte number decrease, leukocyte total number increase by twice, young cell-metamyelocyte appearance, the decrease of total protein quantity and of blood serum gamma-globulin fraction level, liver enzyme activity decrease, and liver function disturbance have been ascertained. The obtained data can be the grounds for the future studies in the field of prognostic criterion development for the evaluation of ionizing irradiation small dose effect on the organism.

[The morphological aspects in a biomedical assessment of hydrobionts]. / Morfologicheskie aspekty v mediko-biologicheskoi otsenke gidrobiontov.

The morphological data are presented on the condition of internal organs in experimental animals during hygienic examination of a number of traditional fish species, as well as the results of the morphological study of the nature of pigment spots on the skin of perch. The problem has been considered on the importance of morphological investigations in the study of harmlessness of hydrobionts. A conclusion has been made on the necessity of conducting thorough morphological investigations of hydrobionts and those structural changes that can be induced by their usage.

[Characteristics of lipids of various species of small fish]. / Kharakteristika lipidov nekotorykh vidov malomernykh ryb.

Fractional and fatty-acid lipid composition studied in some new species of small industrial fish was shown to be specific and typical for hydrodionts: comparatively high nonsaturation of fatty acids, essential amount of polyenic acids with 20 and 22 carbon atoms. The main lipid fractions were presented by triglycerides and phospholipids. The new small fish species studied can serve as an additional source of biologically valuable fatty components in the nutrition of the population.

[Effect of the meat of farm animals fed new nitrogen-containing food additives on the morphologic features of the internal organs in the rat]. / Vliianie miasa sel'skokhoziaistvennykh zhivotnykh, poluchavshikh novye azotsoderzhashchie kormovye dobavki, na morfologicheskie osobennosti vnutrennikh organov krys.

A study was made of the internal organs of rats fed the meat of agricultural animals whose diet included non-protein nitrogen-containing compounds--urea, isobutylidene diurea and a polymer, carbamide with polyacrylamide. Morphological studies have demonstrated that inclusion into the diet of experimental rats of the meat of young bulls given isobutylidene diurea and urea leads to structural alterations in the internal organs of rats, the most pronounced alterations being detected in experiments with the use of the meat of young bulls given isobutylidene diurea. The feeding of experimental rats with the meat of animals grown with the use of the polymer did not affect the morphofunctional status of their organs.

[New type of commercial fish, the triggerfish (Balistes capriscus), in human nutrition]. / Novyi vid promyslvoi ryby kurok v pitanii naseleniia.

Balistes capriscus is characterized by high level of protein (20.0 + 0.12%). The total amount of amino acids reaches 18.52 g per 100 g product, with leucin and lysine being predominant among indispensable amino acids and with limiting amino acids being absent. As regards the content of biologically active fatty acids, Balistes capriscus does not differ from the traditional fish cod. High biological value of Balistes capriscus is confirmed by high rates and degree of peptide bonds splitting by proteinases. The magnitudes of net utilization of cock and cod proteins by the body are identical. Analysis of the data obtained in chronic experiments on animals indicates beneficial effect of Balistes capriscus on the body of albino rats.

[Effect of different kinds of Ocean paste on rat liver biochemical indices in sodium fluoride poisoning]. / Vliianie razlichnzkh vidov pasty "Okean" na biokhimicheskie pokazateli pecheni krys pri intoksikatsii, vyzvannoi ftoridom natriia.

The paper is concerned with the effect of diets including three chemically different types of the "Ocean" paste on biochemical characteristics (glycolysis, the content of phosphofructokinase, dehydrogenase, glucoso-6- phosphate, demethylase, dimethylalaniline hydroxylase, ascorbic acid) of the liver of rats exposed to sodium fluoride overdosage. The test diets were compared with those containing conventional sources of protein (casein, beef). Acute exposure to sodium fluoride caused changes in the biochemical characteristics. The most appreciable changes were seen in the group of rats fed beef. As compared with control, the shifts in the biochemical characteristics were negligible provided the rats exposed to acute and chronic poisoning received the diet supplemented with the paste. No morphological changes were found in the internal organs. The data obtained indicate that the type C "Ocean" paste has a protective action in sodium fluoride poisoning.
