ABSTRACT
OBJECTIVE@#To estimate the significance of myocardial collagen I in the early acute myocardial ischemia of human.@*METHODS@#The myocardial paraffin block had normal group, early myocardial ischemia group and myocardial infarction group. The myocardial collagen I was observed with immunohistochemical staining and analyzed by half-quantity.@*RESULTS@#The similar expression of collagen I was observed in the cytoplasm and nucleolus in two groups.@*CONCLUSION@#The collagen I appeared in the myocardium of early acute myocardial ischemia of human. It may be an important index for postmortem diagnosis of the early acute myocardial ischemia.

OBJECTIVE@#To explore a method of measuring intracranial hemorrhage to be applied in clinical forensic science.@*METHODS@#The accurace of the methods of Tada formula, Stereology and Software boundary to measure intracranial hemorrhage and their practicability were compared.@*RESULTS@#The measured results of Stereology and Software boundary are precise, but the irregularity haematoma volume measured by the method of Tada formula has a high error value.@*CONCLUSION@#The method of stereolgy is the best in measuring intracranial hemorrhage for clinical forensic science.
