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 the methods for sex determination on head CT film. METHODS: To establish the sex determination equations by binary regression analysis of cranial skeletal indices obtained on head CT film. RESULTS: A single element equation by applying the index of the width of ansa capitis and a multi-element equation by applying multitude indices were established. CONCLUSION: The equations for sex determination on head CT film were established.

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.
