Lietuvos šėmųjų karvių kepenų fermentų kitimo dinamika / Lithuanian bovine dynamic changes of hepatic enzymes

Čiučelytė, Ilma 05 March 2014 (has links)
Norint diagnozuoti kepenų funkcijos pažeidimus yra atliekami biocheminiai kraujo tyrimai. Net mažiausius paktimus kepenyse parodo kepenų fermentų padidėjimas, arba sumažėjimas kraujo serume. Mūsų tikslas buvo įvertinti 3 fermentų kitimo dinamiką (laktatdehydrogenazę (LDH), šarminę fosfatazę (ALPL) , aspartatamino transferazę (AST)) ganykliniu ir tvartiniu laikotarpiais. Rezultatai parodė, kad šarminės fosfatazės rodikliai buvo didžiausi tvartiniu laikotarpiu, o ganykliniame laikotarpyje ženkliai krito. Tačiau aspartatamino transferazės ir laktatdehydrogenazės aktyvumas svyravo nepriklausomai nuo laikotarpio. / In order to diagnose a hepatic disorder a biochemical blood test was carried out. Even slight changes in hepatic function show a decrease or an increase in the concentration of hepatic enzymes. Our aim was to monitor 3 enzymes: alkaline phosphatase (ALP), lactate dehydrogenase (LDH) and aminotransferase (AST). From the results of the blood test we deduced hepatic enzyme funcionality of local Lithuanian cow breed („ Lietuvos šėmųjų“). The experiment was carried out during indoor and pasture periods. The greatest activity of alkaline phosphatase was observed during the pasture period and during the indoor period its activity was greatly reduced. The activity of aminotransferase and lactate dehydrogenase was independent on the season.
