The establishment of limitation of death

Forensic importance is the study of the contents of the gastrointestinal tract. From the stomach into the duodenum nutritional content of vegetable origin moves 2-4 h, fatty foods - through 6-10 PM At the small intestine food are moved an hour 180 - 200 see Through the small intestine food content is 3-4 hours There is content in the ascending part of the colon is found after 6 h after eating, in the transverse colon - by 12 hours, in descending part of the colon, after 18 o'clock These data are conditional, but in the General complex of attributes have a certain value.
Definition of limitation of death in cases where the corpse develop a late change in the form of decay or conservation, is in forensic practice even more difficult.
Definition of limitation of death according to the degree of putrefactive changes corpse is very relative importance, as the process of decay is associated with the destruction of the tissues, the intensity of which depends on the variety of effects of endogenous and exogenous factors. However, on some averaged data can be done alleged detention. So, cadaveric greens in iliac regions appears approximately 24-36 hours, the initial signs of putrefaction emphysema you notice after 3 days, expressed emphysema and dying in a greenish color of the skin of the abdomen are determined to 5 days, the emergence of putrefactive bubbles and dirty-green colour of the whole corpse with rejection of the epidermis are observed in 1.5-2 weeks, expressed putrid softening the tissues of the corpse is determined to 3-4 months. Natural skeletization corpse (without the use of animals) with preserved connections bone ligament apparatus can be seen not earlier than upon expiry of one year for full skeletization with the collapse of bone skeleton on the components of the fragments of time is required not less than 5 years, which depends on conditions, in which there were a corpse.
When setting the dates of death of some importance entomological research- based knowledge of the mechanisms of the appearance of the corpse of various insects, some species are consistently involved in the destruction of the tissues of the body. The highest value of the old definition of death has been found on the corpse of the various stages of development of house flies. Normal biological cycle of development of the flies at a temperature of 18-20 OC is 3-4 weeks. When called cycle of the development of the prescription of death can be roughly determined by the following criteria: the presence of the corpse only eggs is an indication that the death occurred about two days ago, detection of eggs and larvae - more than two days, with a large number of larvae is possible to assume, that the death has come about a week, the emergence of pupae shows that from the moment of death passed over a week. All these signs are very tentative, because the cycles of development of the flies can be shortened and lengthened depending on the ambient temperature, and to feel each other and in this case it is impossible to make any concrete conclusions.
Some data for the conclusion of limitation of death can be obtained in the study of the corpse, which is in the state of mummification or fat-wax. Partial mummification of the corpse of an adult, depending on the conditions in which he was, occurs within 2-3 months, full mummification usually can be formed not earlier than in 6 to 12 months. Full mummification of the corpse of the newborn may be over in 3 months.
Fat-wax depending on environmental conditions partially begins to form in 2-3 months. Under favorable conditions (water temperature about 30 degrees C) initial signs of development of fat-wax microscopically are registered already in 2 weeks. Full transformation of the corpse adult fat-wax usually ends after one year. Tissue body of a newborn can switch into a state of fat-wax 4-5 months after the death, and visible initial signs of transition to this state can be detected already in 3-4 weeks.
Most of the above symptoms only approximately indicates the prescription of death, in relatively large ranges of time, it is necessary to note that the expert estimation of some of the early and the later changes corpse can buy subjective.

1. What is for forensic medical examination has the establishing entity of death?
2. Describe the ways and methods of establishment-old offensive the death.
3. Describe the limits of accuracy of the establishment of limitation of death on the basis of the analysis:
a) neuromuscular reactions;
b) the dynamics of temperature of a body of a corpse;
C) the type of muscle rigor;
g) cadaveric spots;
d) entomological and Botanical data.
