摘要： 目的观察尸僵再形成中肌节长度的变化。方法应用扫描电镜测定不同条件下取材的40只大鼠股四头肌肌节长度,判断再僵直的强度。结果死后未破坏的尸僵肌节的长度明显小于尸僵再形成时的长度。结论肌节长度与尸僵强度呈负相关,说明肌节长度可确定尸僵强度,从而为推断死亡时间提供依据。

Abstract: Objective To observe changes of the length of sarcomere of rat when restiffening. Methods We measured the length of sarcomere of quadriceps in 40 rats in different condition by scanning electron microscope. Results The length of sarcomere of rigor mortis without destory is obviously shorter than that of restiffening. Conclusion The length of sarcomere is negatively correlative to the intensity of rigor mortis. Measuring the length of sarcomere can determine the intensity of rigor mortis and provide evidence for estimation of time since death.
