Background & Aim:Cadmium is an important industrial and environmental pollutant. Cadmium is one of the most toxic and carcinogenic heavy metals to organisms. This heavy metal mainly distributes to the liver and kidney in humans and animal and, causing acute hepatic injury. Experimental: The ethanol extract of Satureja hortensis L. (Lamiaceae family), was evaluated for its activity aga...

BACKGROUND A new reference material for the liver enzyme aspartate transaminase (AST) (L-aspartate: 2-oxoglutarate-aminotransferase, EC 2.6.1.1), also called aspartate aminotransferase (ASAT), has been developed under the code ERM-AD457/IFCC. This certified reference material (CRM) for AST has been produced from a human type recombinant AST expressed in Escherichia coli and a buffer containing ...
Relationship between alanine and aspartate transaminases (ALT and AST) and fatty liver on ultrasound
Background: Non-alcoholic Fatty liver disease, also known as NAFLD is said to result from a number of disorders such insulin resistance, Obesity & diabetes mellitus possibly an unhealthy and sedentary life style. The prevalence stated be 25.23%, but it ranges between 115 45% in Asian countries globally. Plasma aminotransferases (aspartate1aminotransferase [AST] alanine aminotransferase [ALT...
In previous studies, the relationship between aspartate aminotransferase to alanine aminotransferase ratio(AST/ALT ratio) and liver disease has been evaluated. In viral hepatitis, alcoholic liver disease and primary biliary cirrhosis, AST/ALT ratio has been proven to be an indicator of liver cirrhosis.1-3 AST/ALT ratio was a potential value in differentiating nonalcoholic steatohepatitis from a...
We examined the kinetics of the catalytic activities of aspartate aminotransferase (AST, EC 2.6.1.1) isoenzymes in serum of 28 patients with myocardial infarction who were to receive either intracoronary urokinase--reperfusion angiographically proved--or conventional therapy (control group). Cytosolic (soluble) AST (s-AST) activity in serum increased rapidly immediately after recanalization, re...
AIMS To assess the place of AST/ALT ratio (the ratio of serum aspartate aminotransferase to serum alanine aminotransferase) as a diagnostic marker in medical populations. METHODS Laboratory tests were viewed retrospectively in three groups of patients: 313 patients with alcohol dependence, consecutively admitted to an alcohol and drug treatment unit for treatment of withdrawal (W) symptoms, 7...
Untrained healthy male volunteers were subjected to the study of the effects of physical exercise (bicycle ergometer, 150 W for 30 min) upon the activities of aspartate aminotransferase (AST [GOT]) isoenzymes, soluble and mitochondrial (AST-s and AST-m) with and without reactivation by the co-enzyme pyridoxal 5'phosphate (PALP) in plasma. Blood samples were drawn at the beginning and end of the...
The diagnostic value of CSF lactate dehydrogenase and aspartate transaminase in cases of brain tumours (except for CSF AST in the benign tumours), congenital hydrocephalus, and brain abscess is established. Tumour cyst fluids show a higher enzymatic activity than does the CSF. The two enzyme estimations do not help in differentiating the supratentorial from the infratentorial tumours. CSF AST i...
