Late changes in the body

  • Mummification
  • Fat-wax
  • Peat "tanning"
  • The destruction of the corpse animals
  • Late changes in the corpse has been slower than earlier, and outwardly manifested later. In normal conditions the corpse is exposed to external factors, the main of which are the oxygen of air, humidity and ambient temperature. Change settings of even one of these factors drastically affect the biochemical degradation processes occurring in the body. Certain types late cadaveric changes finish its formation after months and even years. Depending on environmental conditions corpse may be destroyed or conservation.
    To late transformative, or destructive changes of the corpse include the processes of decay, leading ultimately to the complete disappearance of organic substances. Rot - complex microbiological process, which consists in decomposition of organic substances, especially proteins, tissues and organs under the influence of various microorganisms. Under favorable conditions (sufficient moisture, oxygen of air, positive temperature of the external environment) microorganisms start hard to reproduce, highlighting the large amount of proteolytic enzymesthat break down the organic compounds.
    As a rule, in the process of rotting participate as aerobes and anaerobes. The most intensively this process is developing under the influence of microorganisms belonging to the group aerobes. Under the influence of the anaerobic decay slower pace, with the release of substances having a very unpleasant smell. In the action of microorganisms is observed more or less pronounced pattern. Some break down the protein to Peptones, albums and amino acids, the other to the final decay products; these include Valerian, acetic acid, oxalic acid, cresol, phenol, methane, ammonia, nitrogen, oxygen, hydrogen, carbon dioxide , etc. Among them gases - hydrogen sulfide, methyl mercaptan and ethyl mercaptan, have specific rotting smell. Pathogenic microorganisms when putrid the collapse of the tissues of the corpse under the influence of "banal" flora subject to the General laws of decomposition and therefore infection infectious diseases in contact with a dead body is almost not there.
    The intensity of the process of decay depends on many reasons. The most optimal conditions for rotting corpse arise at an ambient temperature of 30, 40 degrees C. Rot quickly on the air, slower in water and even slower in the soil. Corpses in coffins, especially when they are sealed, rot even more slowly. At temperatures of 0 is 1, and 50, 60 degrees With the process of rotting abruptly slowed down, and at dry air may be stopped completely and the corpse is gradually transformed into the state of the natural mummification. If the death occurred from sepsis or in the presence of other purulent processes, rotting is considerably accelerated. At long atonal States of the barrier function of the large intestine are violated, favouring the spread of intestinal flora in the period of dying, this fact contributes to the simultaneous development of a rotting in all organs.
    Putrefactive processes in the body begin to appear soon after the time of death. Rotting usually begins in the colon and is expressed in education putrid gas emissions. Anatomically blind and sigmoid colon directly adjacent to the front wall of the abdomen. Hydrogen sulfide iscontained in putrid gas penetrates through the intestinal wall, connected with the iron in hemoglobin of the blood vessels of the abdominal wall and forming sulfhemoglobin, colors green anterior abdominal wall in the iliac regions. The first signs of decay in the ordinary room conditions (16, 18 C) appear on the 2-3rd day in the form of a greenish spots in the right, and then in the left iliac regions (cadaveric greens). Then on the 3-4th day due to the increasing pressure of putrid gas in the abdominal cavity microorganisms spread in the venous vessels, rotting blood that forms a putrid venous network of dirty-green colour, it is visible at external examination of the corpse.
    Putrid gases accumulate in the subcutaneous adipose tissue and stretch the skin, forming a cadaver emphysema. Especially hyped be the face, lips, Breasts, abdomen, scrotum, limb. In connection with the formation of cadaveric emphysema body of a corpse becomes unusually large size.
    Gases accumulated in the tissue of the neck and pharyngeal ring, push the language of the oral cavity, and he is due to the teeth. The gas pressure in the abdominal cavity can reach two atmospheres. Under the influence of gases stomach contents can move through the esophagus into the mouth - a so-called post-mortem "vomiting". By this time all the skin of a corpse gets dirty-green colour. The epidermis on separate sites exfoliate, forming bubbles with sero-bloody contents. When the bubble naked wet, brownish-red surface of the dermis.
