Report on two cases, as the ceremony subcutaneous emphysema of the chest without pneumothorax or bony injury blunt chest impenetrable objects. In one case the statement was made by the accused entered the air syringe. To verify the application of air was introduced with 50 ml syringe in dead bodies subcutaneously in chest emphysema can be produced quickly. In the second case was extensive surgical emphysema without pneumothorax or bony injury of the chest. We can conclude that subcutaneous emphysema can occur without bone damage breast, and it can be obtained artificially, but it requires further validation experiments on living. Keywords: subcutaneous emphysema, trauma

39 years old, the injured man was seen by medical staff after in the government hospital with a suspected history of attacking a blunt object, the day of the incident. According to the report injury was diffuse tumor on the left side of the chest on the left forearm. X-ray report showed subcutaneous emphysema of the chest on the left side without bone damage and rib fracture ulna. The doctor received an opinion of the surgeon to know the causes of subcutaneous emphysema. The surgeon opined that subcutaneous emphysema was associated with injury and the doctor suggested that chest trauma life threatening, so serious in nature. The accused complained to the court that the honorable air injection syringe was artificially subcutaneous emphysema and requested the victim to be reviewed with the medical commission. On the order of the court Honorary Medical Board was established and a panel of three doctors examined the patient about the last 2 months. Group of doctors again advised X-ray chest, as in X-Ray reports, there was no bone injury. Medical Board advised bone scan, but no bone injury was found. Medical Board referred the case to the cardio-thoracic surgeon, who also opined that subcutaneous emphysema due to trauma. Looking for adoption ready emphysema was decided to introduce air into the syringe in dead bodies. It became possible to put forward air easily. Thus, emphysema can be done by entering the air but this should be confirmed by experiments in life. At the fifty-five sick man presented as a case of assault with a history of punch in the fall. He was placed in the surgical department. Injured was reviewed medical legitimate aim, as in the report of an injury he had abrasions on the left parietal region, left forearm below the front and back of the left shoulder from behind with subcutaneous emphysema on face neck, shoulders, upper chest. X-Ray chest is showing no bone damage, pneumothorax haemopneumothorax. Repeated X-Ray also advised, but no bone injury was seen. CT scan revealed extensive surgical emphysema from pnevmomediastinuma. However, pneumothorax or chest bone damage can be assessed in CT too. It was in referovanyh breast specialist who also opined that subcutaneous emphysema associated with trauma. Several reductions were made for the treatment of subcutaneous emphysema. Subcutaneous emphysema of the chest after blunt chest trauma in the absence of wounds or injuries bone, usually secondary to pnevmomediastinuma may occur after alveolar rupture. In this case air tracks along the implementation and maintenance of vascular tissue until it reaches the mediastinum. From the mediastinum it is in the subcutaneous tissue neck, chest and forearm. The air can be released directly into the mediastinum after tracheal, bronchial and esophageal rupture due to trauma-1 breast. In our case subcutaneous emphysema after blunt chest trauma in the absence of chest wound or bone injury shows that the subcutaneous emphysema was secondary to pnevmomediastinuma as seen on CT in case 2. If a CT scan was done, and sometimes pnevmomediastinuma can be seen on plain x-rays. In these cases there was no evidence of injury to the trachea, bronchi and esophagus. In both cases there was no pneumothorax and bone injuries. When subcutaneous emphysema hand and forearm due to the high pressure air 2 and the other part numbers because of existing puncture wound 3 hectares have been described in literature. Physical examination is sufficient to diagnose fractures of the ribs almost all conscious patients. In addition, because of difficulties in obtaining good radiographic views of all 30-50% rib fractures may be missed by radiological examination 4. Delayed films 3-6 weeks may show kallusoobrazovaniya place of fracture. Rib fractures occur in about 85% of impenetrable injury 5. Fractures cartilage is difficult to differentiate radiographically, although the films showing fractured sternum indicate the presence of associated cartilage injury, and if its not in the union or false joint developing of X-rays can be helpful. If the report does not. An X-ray examination was done again in about two and a half months, so the formation of bone callus should be obvious, or have missed destruction through poor vision in the previous radiographic films. Second, in this case, bone scans to exclude evidence of bone injury. Similarly in the second report of the CT of the chest was made also possible bone and cartilage injury. In this case, appears to be injury of the lungs, pleura, trachea, bronchi and subsequent subcutaneous emphysema of the edges of the cracks. Losses in bone or soft tissues of the chest may be mistakenly interpreted as representing thoracic disease and the most important diagnostic feature. Subcutaneous emphysema may be more apparent than primary pneumothorax. Two muscles are usually visualized. Anterior axillary fold is formed by the pectoral muscles seen curved medially and downwards from the armpit to the chest. In muscle men, big chest look like a continuation of the anterior axillary time, passing obliquely both lungs. This muscle is responsible for increased surveillance of the middle and upper lung. In the absence of this region will lead to increased transparency in the lungs and misleading impression of emphysema 7, but in both cases, the muscle was present. It seems that it is reasonable to conclude that subcutaneous emphysema can be obtained by introducing air through a syringe, but this requires confirmation by further experiments in life. Needle puncture marks can be detected by careful study, but difficult to detect, if examined after a long time, as seen on occasion 1. In all such cases, the CT / MRI should be encouraged, as is the case 2. Pseudomediastinum indicate injury can be assessed only after CT. A. Crofton and Douglas. Respiratory disease.

Next we consider the stimulation of division ...

likely scenario will be the first autoreaktivnyh cells escape negative selection, do not feel it yourself and the environment as antigens of immature cells. This cell maturation is naive in the population where it can be stimulated by self antigen or allergen. Antigenic stimulation causes the cells multiply in a little autoreaktivnyh memory cells. These autoreaktivnyh memory cell may still require survival factors survival or rapid reproduction. If so, increased competition for survival factors can suppress this cell clone, and thus prevent the disease. Suppression autoreaktivnyh cells thus accompanied by passive depletion of the memory population. Large values ​​of attrition, and leads to more rapid loss of immunological memory. On the other hand, long-term stable population of memory should be low value of attrition, and so people with greater ranger of values ​​

will grow. Inequality in the formula. 6 defines the boundary between the suppression and the spread, which is a function of rate of infection. shows the pedagogical example. The value

large enough to suppress them. Similarly it is possible that all >> << value below a certain threshold can be suppressed homeostatic sources of attrition, although this is not a common feature of all niches. Conversely, if we consider the external environment, which is well characterized by a specific value, the border in the figure defines the lower limit autoreactivities we are likely to find in this environment. Low cost >> << related BЂњfilthyBЂ Wednesday ". The following subsections we approach curve data for human and mouse CD

T-cell memory to make quantitative predictions for these borders. We can find the asymptotics of passive depletion autoreaktivnyh suppression in the limit of rare infections, i. e low. Balance the total number of memory cells for a given rate of infection is given. This is simply the value

, for which the right side of the equation. 1 is equal to zero, the homeostatic balance. If we consider the case when the level of contamination is small enough that the amendment K. In this limit equation. 7 is reduced to the form obtained by Anti et al. etc.

As seen from this equation, clones with

). is zero and there is no lower limit on the ability autoreaktivnyh cells to proliferate in sterile conditions. Asymptotics of the border that divides the field stop and be present around the curve. This asymptotic behavior can be seen an inch, and that it is a common feature of homeostatic regulation. For large values ​​>> << it may not be possible to satisfy the equation. 6. This is demonstrated and discussed in the following subsections, where we model cell homeostasis in IL-15 regulated niche (CD

T-cell memory) cells and IL-7 niche (CD

and naive T cells), respectively. There we also give quantitative predictions for the speed range of antigenic stimulation. pool of memory T cells. These cells differ from effector memory, the presence of a high level of CD122 on the cell surface. CD122 protein is part of the receptor for IL-15. In the absence of IL-15 CD

memory T cells can not survive. Other cell types usually has no effect on IL-15 knockout mouse

shows that the niche is not universal and that competition between cells that niche for IL-15 should have little impact on other cell types. We also know that sterile environment memory population in this niche is stable yield. In the homeostatic equilibrium total number of cells remains constant. Since there is no homeostatic influx of new cells in this pool (

) as homeostatic division rate

is a population, the first term on the right side represents the population growth by division, and the second is reduced by apoptosis. Number. Judge et al. Memory T cells in IL-15, a saturated solution. In saturated environments might be expected, if the equation. 11 were correct description we see the proliferation rate of the population level. Instead of the population was observed twice in less than three days, excluding the equation. 11, is really a model. From this we conclude that IL-15 not only inhibit apoptosis. Next we consider the stimulation of division by IL-15, described by the equation, and increasing growth. Another experiment Judge et al. Memory T cells in IL-15 in mice. In the absence of IL-15 and stimulating antigen, Equation 12 predicts the collapse of the number of cells with speed. Observed decline was approximately 2 weeks

according to the model. This means that in first approximation, IL-15 stimulates the division. We can compare the homeostasis is expressed in the formula. 12 of our general model to obtain the asymptotic limit of the suppression that separates from the suppression of proliferation described by the equation. 6. Our previous requirement that requires that

Physically, this corresponds to cells that can support the number of antigenic stimulation alone (characterized by large
