Expression of iNOS on brain tissue in rats model of asphyxia death / 重庆医科大学学报

ABSTRACT

Objective:To compare expression of iNOS on brain tissue in rats model of asphyxia death with other death groups and forensic significance.Methods:The production method of mechanical asphyxia death,hemorrhagic shock death,brain traumatic death and breaks the neck to execute group model;By means of immunohi stochemistry and image analysis technology to determinate the dead rats after each group at different times of iNOS in the brain tissue of expression.Results:iNOS in mechanical asphyxia death,hemorrhagic shock death and brain traumatic death have expressed,breaks the neck to execute was no expression and mechanical asphyxia death group was significantly higher levels than in all levels of other group,each group of 0h expression all slightly bottom to 6h,12h,24h,Also each group of 6h,12h,24h expression tends to the identical level.Conclusion:This discovery,in the 24 hours after the death of brain tissue iNOS expression can be inferred from the asphyxial death of a biological indicators.
