Abstract:
Objective Investigating activity variance of PKC.AchE and HSP70 in different tissues of rabbits caused by dying from suspension of anterior limbs.in order to study how factors above contribute in the mechanism of death.Methods Suspend rabbit by its anterior limbs until it dies.and coilect tissue from its diaphragmatic muscle,intercostal muscle,myocardium,gastrocnemius,cerebrum,brain stem,liver,kidney and lung.In the control groups,collect same tissues of rabbits dying from strangulation,craniocerebral injury and diseases as contrast.Detect activity of PKC,AchE and HSP70 in tissues of those groups mentioned above by SP stain of immunohistochemistry.and statistically analyze result of detection by rank SUm test of independent samples of multi-groups.Results Compared with data from other control groups,there are more obvious expressions in following tissues of group of suspension:PKC in disphragmatic muscle,intercostal muscles and cerebrum(P＜0.05);AchE in disphragmatic muscles,intercostal muscles,myocardium,cerebrum,liver and nerve tract ofmuscles(P＜0.05);HSP70 in cerebrum,myocardium and lung(P＜0.05).Conclusion Through different mechanisms,PKC,AchE and HSP70 could take some certain contributions in death pmcess of suspension by anterior limbs,and the results above could offer some experimental evidences for related studies and medicolegal investigations.
