Electric and chemical excitability of muscles present a supravital reaction which is of major importance in achieving a more precise estimating of the time since death in the early post-mortem period. The purpose of this paper is to examine the electric and chemical excitability of the muscles in cases with a known time of death, in order to determine their importance in the estimation of time since death. Electric excitability and chemical stimulation have been analysed in 50 cases with a known time of death, taken for autopsy at the Institute of Forensic Medicine and Criminology in Skopje in the course of the year 2005. Testing of electric excitability of the muscles was done with a device for electric stimulation, providing a direct current of 50 mA intensity and 50 Hz frequency. Testing of chemical excitability of the eye pupils was done by injecting miotic Carbahol into the front eye chamber of the right eye and mydriatic Adrenalin HCl into the front eye chamber of the left eye. By analysis and processing of the obtained results, it was determined that the electric excitability of the muscles is of a major importance in determining the time since death within a post-mortem period of up to 10 hours and chemical excitability for a post-mortem period of up to 12 hours.
肌肉的电兴奋性和化学兴奋性呈现出一种超活反应，这对于在死后早期更精确地估计死亡时间至关重要。本文的目的是研究已知死亡时间案例中肌肉的电兴奋性和化学兴奋性，以确定它们在估计死亡时间方面的重要性。对2005年期间在斯科普里法医学与犯罪学研究所进行尸检的50例已知死亡时间的案例进行了电兴奋性和化学刺激分析。使用电刺激装置对肌肉的电兴奋性进行测试，该装置提供强度为50 mA、频率为50 Hz的直流电。通过将缩瞳剂卡巴胆碱注入右眼眼前房，将散瞳剂盐酸肾上腺素注入左眼眼前房来测试眼瞳孔的化学兴奋性。通过对所得结果的分析和处理，确定肌肉的电兴奋性在确定死后长达10小时的死亡时间方面至关重要，而化学兴奋性在死后长达12小时的时间段内至关重要。
