VARIATIONS BY EPINEPHRINE OF HEPATIC AND SERUM AMINOTRANSFERASES AND LACTATE DEHYDROGENASE IN THE RAT

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 ...

Synthesis and Degradation of Rat Liver Lactate Dehydrogenase M4 HYBRIDIZATION IN THE PURIFICATION OF LACTATE DEHYDROGENASE

For the measurement of lactate dehydrogenase (LDH) isoenzyme biosynthesis a new method is presented which is based on the quantitative hybridization of isoenzyme MI with isoenzyme Hq. After reversible dissociation the formation of active LDH M4 was more rapid and occurred to a greater extent than the formation of LDH Hq. The formation of hybrid isoenzymes from the two subunits resulted in an in...

Lactate dehydrogenase: An enzymatic biomarker in oral health and disease

Lactate dehydrogenase (LDH) is a ubiquitous enzyme, which has the pivotal role in the clinical diagnosis of many disease processes. LDH is known to catalyze the oxidative conversion of the substrate pyruvate to lactate and has been used as an infl ammatory marker. LDH is routinely present in the cytoplasm of the cell that gets released into the extracellular environment upon cellular lysis and ...
