The surviving myocardium of the cat was studied 7 days and 6 weeks following experimental infarction. Seven days after infarction, ultrastructural alterations of the mitochondria indicative of slight hypoxic injury--clearing of the matrix and loss of dense matrix granules--were found. Together with
The course of plasma catalytic activities of total creatine kinase, creatine kinase isoenzyme MB, total, cytoplasmatic and mitochondrial aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, alpha-hydroxybutyrate dehydrogenase, glutamate dehydrogenase and concentrations of
A complex of enzymatic tests, characterizing the liver function and cellular cytolysis in patients with acute myocardial infarction of various severities (without complications and with various types of complications and outcomes) was used in examinations over the first week of the disease.
Changes in some values of protein metabolism in the heart muscle (the activity of myosin ATPase, leucilaminopeptidase, glutamate dehydrogenase, as well as the content of SH-groups, urea, RNA and DNA) were studied by histochemical methods in the parts of the myocardium remote from the zone of the
Ischemia initiates a complicated biochemical cascade of events that triggers neuronal death. This study focuses on glutamate-mediated neuronal tolerance to ischemia-reperfusion. We employed an animal model of lifelong excess release of glutamate, the glutamate dehydrogenase 1 transgenic (Tg) mouse,
We studied serial changes in various myocardial enzymes and cardiac myosin light chain II (LCII) in plasma following coronary ligation in 14 conscious closed-chest dogs. Cytoplasmic enzymes [creatine phosphokinase (CPK) and supernatant glutamic oxaloacetic transaminase (sGOT)] reached maximum at
