[Estimation of postmortem interval using myofibril fragmentation index].

OBJECTIVE: To study the relationship between postmortem interval and the myofibril fragmentation index of skeletal muscle. METHODS: Rabbit skeletal muscle were left in the room temperature for different postmortem intervals, and the protein concentration of each sample was detected by using biuret method. Furthermore, the myofibril fragmentation index of each sample was measured under the protein concentration level of 0.5 mg/mL. RESULTS: The myofibril fragmentation index increased obviously according to the postmortem interval prolongation. CONCLUSION: The myofibril fragmentation index may be used on the estimation of early postmortem interval.

[Study of CTnI immunohistochemistry on acute myocardial infarction in rabbits].

OBJECTIVE: To investigate the signification of CTnI in acute myocardial infarction. METHODS: The model of myocardial infarction was established by ligating the left ventricle branch. Immunohistochemistry and image analysis were used to detect the change of CTnI in the model, and The sensitivity of immunohistochemistry and HE coloration were also compared. RESULTS: The acute myocardial infarction tissue showed obvious depletion of CTnI, there was no characterization of myocardial infarction in HE coloration. CONCLUSION: CTnI is sensitive to diagnosis of acute myocardial infarction.
