[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.
