In previous study, various stainings of experimentally produced myocardial infarction were examined and considered about their specificity, reliability and practical use. HBFP and PTAH staining methods were useful to detect the early myocardial infarction.In this report, these two staining methods were examined about the usefulness for human autopsy cases. In nine fresh myocardial infarction, six of them showed the regional similarity in PTAH and HBFP positive areas, the similarity in remainders were partially. In the earlier lesion, HBFP method stained stronger than PTAH. As lesion becomes older, PTAH positive area become to be stronger. In operation materials positive findings were variable. In control, false positive areas were found at intermediate zone. These findings were mostly due to unskillfull decolorization technique.From the results of our study, it was thought that the early myocardial infarction could be successfully diagnosed by the combination of HBFP and PTAH staining methods.
