[Behavior of some serum enzymes and proteins in experimental revascularization of acute myocardial infarct].
Effect of reoxygenation of the serum enzymatic activities and protein fractions in dog with acute myocardial infarction. The enzymatic activitites creatin phosphokinase (CPK; E.C. 2.7.3.2), glutamate oxalacetate transaminase (GOT; E.C. 2.6.1.1.), diamine oxidase (DAO; E.C. 1.4.3.6.), monoamine oxidase (MAO; E.C. 1.4.3.4.), catalase (E.C. 1.2.1.6.), peroxidase (E.C. 1.2.1.6.) and the protein fractions levels are measured in the dog serum during experimental myocardial infarction, followed by 2 hours of reoxygenation. The alpha, and alpha2 globuline serum proteins increase during anoxic period; after reperfusion alpha1 globuline content further increase again, while alpha2 globuline fraction decrease to control values. The enzymatic activities, particulary CPK, DAO and MAO, significantly enhance during coronary occlusion. After riperfusion the DAO, GOT and peroxidase activities decrease, while the CPK, atalase and MAO activities further increase, particulary at the early stage of the reperfusion. These results are discussed interms of cellular mechanism, induced by oxygen readmission.

Separation and characterization of histones and acidic proteins from heart muscle and calf thymus.
A method for the isolation of histones and acidic proteins extracted from rabbit heart and calf thymus chromatins has been studied. The histones present five major electrophoretic fractions in both tissues. Only lysine rich fraction in the heart splits into three peptides of different mobility. Amino acid composition of total histones shows values very similar in almost all components. The acidic proteins of rabbit heart and calf thymus have been characterized by sodium dodecyl sulphate polyacrylamide gel electrophoresis and by amino acid composition. The electrophoretic pattern reveals reproducible heterogeneous banding pattern from the two sources with different degree of phosphorylation. The amino acid composition of total acidic proteins is quite similar with the exception of serine content that in the heart is most elevated.
