Abstract

The objective of this study was to investigate the degradation pattern of cardiac troponin I in rats in vivo, and to determine whether the pattern was dependent on the cause of death, for the purpose of estimating the postmortem interval. The rats were categorized into three distinct groups depending on the factors leading to their demise: the control group, the group experiencing acebutolol-induced cardiotoxicity, and the group affected by asphyxia. The analysis encompassed the isolation and segregation of the protein, subsequently employing Western blotting as a means of visualizing the results. The results revealed a distinct degradation pattern of cTnI into smaller fragments over time, indicating that cardiac troponin I can serve as a reliable marker for estimating the postmortem interval. Furthermore, noteworthy variations were noted in the degradation pattern of cardiac troponin I among the different causes of death, which suggests that this method can also be used to determine whether cardiac failure was the cause of death or not.

在因窒息和阿西布洛尔心脏毒性死亡的情况下,使用心肌肌钙蛋白I估计死亡后的时间。
本研究的目的是研究大鼠体内心肌肌钙蛋白I的降解模式,并确定这种模式是否取决于死亡原因,以估计死后间隔时间。根据导致大鼠死亡的因素,将其分为三组:对照组、经历阿西布洛尔诱导的心脏毒性的组和受窒息影响的组。分析包括蛋白质的分离和分离,随后采用蛋白质印迹作为可视化结果的手段。结果显示,随着时间的推移,cTnI有明显的降解模式,分解成更小的片段,这表明心肌肌钙蛋白I可以作为估计死后间隔的可靠标志物。此外,在不同的死亡原因中,心肌肌钙蛋白I的降解模式存在显著差异,这表明该方法也可用于确定心力衰竭是否是死亡原因。
