The activity of aspartate aminotransferase (AST) in human serum has been widely determined as a diagnostic aid in liver disease. In this study, the effect of aluminium on AST isoenzymes in relation to aluminium intoxified patients has been investigated. Using gel filtration chromatography technique with Sephacryl S-300, mitochondrial aminotransferase (m-AST) and cytosolic aminotransferase (c-AS...

Elevated enzyme activities in plasma may at times be attributed to the presence of macro-enzymes. The macro-enzymes are often serum enzymes in complex with immunoglobulins, resulting in a greater molecular mass that cannot be filtered by renal glomeruli and are, hence, retained in the plasma. The aspartate aminotransferase (AST) can exist as a macro-enzyme, although it has been rarely reported....

Incubation of rat hepatocytes with epinephrine inhibited alanine aminotransferase (ALT) (80%) and aspartate aminotransferase (AST) (53%) activities with no effect on lactate dehydrogenase (LDH) activity. Injection of epinephrine caused a progressive increase with time in hepatic LDH activity, being 52% at 24 h. Preinjection with propranolol eliminated the hormone effect and caused further ...

A 60-days feeding trial was conducted to study the effect of higher temperature (32°C) in comparison to ambient temperature (24.5°C) on different metabolic enzyme namely, aspartate aminotransferase (AST), alanine aminotransferase (ALT), adenosine triphosphatase (ATPase), acid phosphatase (ACP) & alkaline phosphatase (ALP) activities in different tissues of Pangasianodon hypophthalmus. AST activ...

background: liver ischemic insults are important sources of liver injuries leading to production of reactive oxygen species (ros) and mediating liver cell injury. glutathione mediated mechanisms are among the most important defense mechanisms of the liver; n-acetylcysteine (nac) provides cysteine for glutathione defense mechanisms. patients undergoing cardiac surgery are at increased risk of li...
