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...

t-2 toxin, a trichothecene mycotoxin, is considered to be one of the most toxic compounds that are produced by molds, particularly the fusarium species. fusarium species have been recognized as a great agricultural problem. they occur worldwide on a variety of plant hosts and cereal grains. the aim of this study was to investigate t-2 toxin-induced liver injury using in situ perfused rat liver....

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...

Administration of cortisol to rats enhanced brain tyrosine:2-oxoglutarate aminotransferase activity by a mechanism excluding stabilization, but possibly involving enhanced synthesis, of the enzyme.

By using an antiserum raised against rat liver tyrosine aminotransferase, it was shown that about 60% of tryptophan aminotransferase activity in rat liver extracts is catalysed by this enzyme. Induction of tryptophan aminotransferase activity by intraperitoneal injections of tryptophan or triamcinolone can be entirely attributed to the effects of these agents on tyrosine aminotransferase. The o...
