in this study 110 samples of amniotic fluid of sheep at different stage of pregnancy were assessed for creatinine (cr), alkaline phosphatase (alp), aspartate aminotransferase (ast), creatin kinase (ck), lactate dehydrogenase (ldh) and arginase. significant increase (p

SUMMARY Three pa ticnts admitted because of slightly increased serum amino trans fcrases were found to have Addison's disease. A review of 16 other patients with addison 's disease who had serum aminotransferase activity (aspartate aminotrans­ferase (ASAT) and alanine aminotransferase (ALAT) J determined prior to treatment revealed one more patient with slightly increased aminotransferase acti...

Molecular dynamics simulations of myoglobin and aspartate aminotransferase, with explicit solvent, are shown to accurately reproduce the experimentally measured molar volumes. Single aminoacid substitution at VAL39 of aspartate aminotransferase is known to produce large volumetric changes in the enzyme, and this effect is demonstrated in simulation as well. This molecular dynamics approach, whi...

Elevated enzyme activities in plasma may sometimes be due to the presence of macroenzymes.1,2 Macroenzymes are high molecular mass complexes of plasma enzymes with immunoglobulins (IgG, IgA or IgM) or other plasma components with reduced plasma clearance and prolonged half life, resulting in elevated serum activities due to the “trapping” of the enzymes in serum.3 These results may thus be erro...

Heart tissue injury may release cardiac enzymes into the circulation and elevate serum enzyme levels (LaDue, Wroblewski, and Karmen, 1954). Many enzymes become raised, but three enzymesaspartate aminotransferase (EC 2.6.1.1), creatine kinase (EC 2.7.3.2), and lactate dehydrogenase (EC 1.1.1.27)-have proved of particular diagnostic value. In addition, determination of lactate dehydrogenase isoen...

1. Alanine Aminotransferase (ALT) Alanine aminotransferase measurements are used in the diagnosis and treatment of certain liver diseases (e.g., viral hepatitis and cirrhosis) and heart diseases. Elevated levels of the transaminases can indicate myocardial infarction, hepatic disease, muscular dystrophy, or organ damage. Serum elevations of ALT activity are rarely observed except in parenchymal...
