MYOCARDIAL INFARCTION

HISTOPATHOLOGIC STUDY OF EARLY EXPERIMENTAL MYOCARDIAL INFARCTION IN DOGS (1)

Abstract

Various staining methods of experimentally produced myocardial infarction were examined and compared about their specificity, reliability and practical use. Results obtained are as follows: ischemic areas showed positive staining as early as 1 hour after coronary ligation by HBFP staining and later, PTAH and Azan staining methods revealed pathologic changes of myocardium. Ischemic myocardium was homogenous purpule in colour and Azan staining is purpulish-red. To detect the effect of early myocardial infarction, HBFP, PTAH and Azan staining methods are useful.
