利用人骨骼肌在死亡早期阶段能对电刺激产生兴奋和收缩的特点,以加大刺激强度为手段,对18例死亡早期阶段(1小时25分至6小时40分)具有超生反应能力的尸检骨骼肌和17例稍晚阶段(10~60小时)不具有超生反应能力的尸检骨骼肌,进行了电刺激损伤的系列形态学对比研究。结果表明,死亡早期阶段的肢体骨骼肌,经电刺激后,能产生整个肌肉或局部肌肉的收缩;在电极周围以及电路中的肌纤维形成大片的极具特点的收缩带、条带状嗜酸性变、高度变形的节段状和盘片状崩解等改变;稍晚期阶段受刺激的肌纤维则未见上述改变。探讨形态学改变的形成机理及意义,为研究死亡早期阶段的电损伤提供形态学基础。
Using the characteristics that human skeletal muscle can excite and contract electrical stimulation in the early stage of death, 18 patients with early stage of death (1 hour 25 minutes to 6 hours 40 minutes) have autopsy ability autopsy by increasing stimulation intensity Skeletal muscle and 17 autopsy skeletal muscle with no hyperactivity at a later stage (10-60h). A series of morphological comparative studies of electrical stimulation injury were performed. The results showed that the limb skeletal muscle in the early stage of death could produce the contraction of the whole muscle or the local muscle after electrical stimulation. The muscle fibers in the circuit and around the electrode formed large and characteristic contractile bands, , Highly deforming segmental and disk-like disintegration; the above-mentioned changes were not observed in the muscle fibers stimulated in the later stage. To discuss the formation mechanism and significance of morphological changes and provide morphological basis for the study of electrical injury in the early stage of death.
