Late changes in the body

Formed by the decay dirty-bloody fluid penetrates tissues and organs of the body, derived from its natural holes. The brain becomes flabby, dirty-green colour, easily spread by touch. Light dirty-gray, in connection with putrid impericia become somewhat sealed, then softened. Heart flabby, grayish-red, as if "is spread on the table. The mucosa of the stomach and intestine becomes dirty-red color, okisnogo nature. Gradually decay exposed and other internal organs, and the longest remain non-pregnant uterus, prostate; ligaments, cartilage.
Depending on the conditions of burial (the nature of the soil, pollution, and so on) approximately to two years tissues and organs take the form of decaying homogeneous dirty-gray mass, exposing the bones of the skeleton that can last indefinitely.
For the identification of dead bodies in a state of putrefaction, apply various methods of restoration.
The corpses are in the earth, gradually changing hair color from dark brown they are reddish brown, sometimes reddish, that it is necessary to bear in mind when identifying exhuming corpses. To change the color of hair you need at least three years.
No degree of putrefaction of the corpse is not the basis for refusal from forensic studies. Even with a pronounced decomposition of the corpse can be identified various injuries, especially on the bones, traces shot on the skin, phenomena cardiosclerosis, etc. that has expert diagnostic value.
Dynamics of development of the rotting process can have an approximate value for determining the limitation of death.
In the study of dead bodies in a state of considerable putrefaction, you can avoid a number of errors in the evaluation found signs, which is the direct consequence of the rotting process.
Under the pressure of accumulated gases from the oral cavity is the tip of the tongue is a phenomenon can be taken as a sign of mechanical asphyxia during the hanging. Bubbles formed on the skin of a corpse due to detachment of the epidermis and the accumulated liquid, remind second degree burns; the nature of the liquid (a significantly lower nitrogen content) and the absence of reactive phenomena easily distinguish between these two different in origin education. Greenish color putrid venous network remotely resembles the shape of a lightning", which occurs on the skin with the defeat of atmospheric electricity. Coming in the process of rotting dilution of fabrics accompanied by the formation of bloody fluid that is released through natural openings. These captures mistake can be taken for uterine, gastric, lung hemorrhage. In rare cases, especially when the exhumation of corpses pregnant, between the legs can detect loose the corpse of the fetus. This so-called post-mortem "childbirth", which arise due to the pressure of gases accumulated in the abdominal cavity, on the uterus, containing fruit. As a rule, this phenomenon is accompanied by eversion of the uterus. In some cases in the lumen of the esophagus, mouth, throat and respiratory major bronchi found the food supply. This may cause suspicion vomiting allegedly lifetime of origin and subsequent aspiration of food content in the respiratory tract, which may mistakenly assume death in the result of mechanical asphyxia, zadaszenia vomit. Food masses passively flows into the windpipe, never penetrate further large and sometimes medium-sized bronchi. Penetration of gas into the lumen of the blood vessels and heart cavity leads to the frothy blood condition that it is a mistake can be taken for the gas or air embolism lifetime of origin. Sometimes on the fascia and serosa of the internal organs can be seen multiple grayish color, solid, irregular crystal-like deposits, which is a consequence of formation of salts oxiranylmethyl acid, resulting in hydrolytic cleavage of proteins. These overlays may be mistakenly perceived as falling crystals adopted during the life of the poison.
A thorough investigation of certain acts described putrefactive changes and analysis of their origin always allows the expert to differentiate postmortem changes and lifetime.
When excluding the impact of one of the environmental factors (air oxygen, humidity, positive temperature) the rot is suspended. Influence of low temperature leads to cooling of the corpse, interrupting the biochemical processes of decomposition. It forms a late change of the corpse, which are preserved, include mummification, the formation of fat-wax (saponificare), "peat tanning".
When these and other forms of corpses can completely maintain their appearance or change, preserving individual features that let you authenticate your identity, to identify the features previously obtained damage to define an environment in which there was a dead body, to judge the elapsed time from the moment of death, etc.,
Currently, the methods of artificial preservation apply for a short preserve dead bodies before burial, and also for manufacturing of Museum and educational products; special methods of preservation of tissues and organs are used for the needs of transplantation.
