title: [The effect of fatty acids in the feed on xanthine dehydrogenase activity in the Japanese quail].
abstract: The aim of the present study is to determine the effect of different fatty acids on the amino acid catabolism judged on the level of xanthine dehydrogenase (XDH). The model system of protein depletion with subsequent repletion was used in the trial consisted of Japanese quails 71 days old. In the period of protein repletion, the fatty acid (stearic, palmitic, oleic, linolenic, linoleic and lauric, respectively) was used instead of common fatty compound in the diet. Specific activities of XDH in liver, kidneys and pancreas of quails were tested dynamically from the first to the eighth day of feeding. It was demonstrated that neither lauric, palmitic nor oleic acid, respectively, had an effect on the development of the specific activity of XDH (Fig. 3). Stearic acid as a sole fatty compound in the diet however evoked reactibility of XDH in liver or in pancreas in different way as in kidneys (Fig. 4). The dynamics of the XDH development in kidneys was practically identical than that in the control. However, XDH in liver and pancreas raised statistically already from the first day of feeding. The effects of linoleic and linolenic acids on the development of specific activity of XDH were organ selective, too (Fig. 5). XDH in kidneys was shown in the same manner as in the control group. In liver and pancreas, however, the specific activity of XDH was diminished markedly just from the first day of feeding.
