The objective of the present work was to study dynamics of the temperature of a corpse of an experimental animal (a pig) between the moment of death till complete skeletization, The porcine corpse weighing approximately 100 kg was placed in the bilberry spruce forest in the southern part of the Karelian Republic. Variations in the temperature of the corpse were measured with the use of the EClrerk-USB-2Pt logger (an autonomous register of temperature) along with those of the environmental (the air and the soil) temperature during 86 days in the period from June till September. It was shown that the temperature of the corpse first decreased but began to increase thereafter due to the enhancement of the biological activity of microorganisms. It is concluded that putrefactive decomposition of the corpse does not always suggest the necessity to discontinue the measurement of its temperature. The forensic medical examination of a corrupted corpse should take into consideration the possibility of an increase of its temperature in the course of time because it may be a source of a mistake when estimating prescription of death coming. The problem of postmortem rise in the temperature of a corpse undergoing putrefactive decomposition needs a thorough theoretical interpretation with a view to promoting the practical application of the proposed method with due regard for the difference in the environmental conditions in various climatographical regions of the Russian Federation.
本研究的目的是研究实验动物(猪)尸体从死亡时刻到完全骨骼化期间的温度动态。将一头重约100公斤的猪尸体放置在卡累利阿共和国南部的越桔云杉林中。在6月至9月的86天内,使用EClrerk - USB - 2Pt记录仪(温度自动记录仪)测量尸体温度以及环境(空气和土壤)温度的变化。结果表明,尸体温度最初下降,但随后由于微生物生物活性增强而开始上升。得出的结论是,尸体的腐败分解并不总是意味着必须停止测量其温度。对腐败尸体的法医检验应考虑到其温度随时间升高的可能性,因为这在估计死亡时间时可能是错误的来源。鉴于俄罗斯联邦不同气候区域环境条件的差异,为了促进所提出方法的实际应用,腐败分解尸体的死后温度升高问题需要进行深入的理论解释。
