The results of a study on the composition and rheological properties of solutions after separation of glaserite, as well as the influence of technological parameters on the process of evaporation of mother liquors in the production of potassium sulfate by conversion of flotation potassium chloride with mirabilite of the Tumryuk deposit, are presented. The most intensive process of evaporation of the mother liquor, after separation of the glaserite, proceeds at a temperature of 100°C. In this case, after 60 minutes, the volume of the solution decreases by more than 50%, while at 80 and 60°C these figures are 20 and 5%, respectively. With an increase in the volume of the evaporated liquid from 5% to 40%, the amount of precipitated sodium chloride increases from 3.1% to 22.9% of the mass of the initial mother liquor containing (wt.%): K2O-6.86; Na2O-11.67; SO4-2-3.46, CI--16.02; H2O-66.26 at 20°C. The density of the mother liquors with an increase in the volume of the evaporated solution increases from 1.250 g/cm3 to 1.358 g/cm3 at a temperature of 20°C and from 1.210 g/cm3 to 1.330 g/cm3 at 80°C, the viscosity decreases from 2.126 mPa s to 2.007 mPa s upon evaporation of 40% moisture and up to 0.914 mPa s when the temperature rises from 20°C to 80°C.

Topicality and demand of the subject of dissertation. In the world lat days chanchcd structures of trauma, increase the number of heavy combined traumas, which resulting in more heavy nature of simultaneous injuries of three , four or more anatomical regions, which creates difficulties in determining of the order of care and surgical tactics in patients with combined traumas of the facial skeleton bones (CTFSB). The syndrome of mutual burdening injuries of various anatomical regions, variety, hcavity and speed of the development of pathological process did difficulty of diagnosis of the CTFSB. Complexity of the clinical picture, features of the progress of post-traumatic shock, the development of traumatic disease cause difficulties which arise in the course of examination of patients and put tasks to the experts to find new ways of developing diagnostic algorithms and early surgical treatment of the CTFSB.
Frequency of CTFSB ranges from 34,8 to 63,3%. Fractures of orbit has been observed with an extremely high frequency (98%) in CTFSB, injury of the orbit is accompanied by damage of the eyeball and its subsidiary bodies has been observed in 66 % of eases. Consequences of eye injuries arc becoming the leading cause of disability and in 50% of eases could cause permanent loss of vision. By reason of death combined trauma take the third part after coronary heart diseases. Frequency of disfiguring defects and deformities of face occurs in 12 and 57%, disability in CTFSB reaches up to 23%. CTFSB, combined with TBI, causes up to 60% of deaths.
The causes of unsufficient results is non-availability of a diagnostic algorithm, which includes the most informative research methods, determining the order of interaction and priority of work of doctors of various specialties in CTFSB.
In some eases, requires specified an indications, character, scope, sequence and timing of surgical interventions, depending of the objective assessment of heaviness of injuries to various anatomical regions, prognosis criteria, the nature and heaviness of life-threatening consequences of combined trauma. The research work earned out within the framework of the achievement of the set by the Decree of the President of Republic of Uzbekistan “About measures on the further deepening reform the health care system” November 28, 2011, № PD-1652, maintenance of high-quality medical aid to the population under modem requirements and standards.In this regard the need for the development of algorithms of diagnosis and early methods of surgical treatment of patients with CTFSB constitute one of the important criteria demand the theme of dissertation.
Purpose of research is improvement of the diagnostic tactics and therapeutic interventions in patients with acute combined injuries of the facial bones according to the severity and location of the injury.
Scientific novelty of disscrtational research consists in the following: revealed the structure and features provide consistent care to patients with combined injuries in Republic of Uzbekistan;
The sequence of diagnostic and therapeutic measures, depending on the patient's general condition with CTFSB first determined by using created CT program "ADIL
developed innovative methods for early reduction and fixation of bone fragments in CTFSB;
identified endogenous factors, affecting on the wound process, disclosed the mechanisms of post-traumatic complications in CTFSB;
proved, that at 2 - 3rd days after the injury occurs the depression of cell and humoral immunity in the blood. Increases the level of proinflammatory cytokines, reduced the level of anti-inflammatory cytokine (in 2,8 at patients with heavy commonl condition. Increased levels of pro - and reducing anti - inflammatory cytokines is a poor prognostic factor in the development of inflammatory complications (bone wound suppuration, osteomyelitis of the jaw bones, soft tissue abscess);
patients with CTFSB at 2 - 3rd days after the injury occurs the depression of the content of protein and micronutrients (calcium, potassium and phosphorus) in the blood, which is a prognostic factor of the development of complications;
a scheme was developed for integrated medical correction of endogenous factors affecting on the development of posttraumatic complications;
1. CTFSB in 100% of cases combined with TBI, in 27.7 % with injuries of skeleton and internal injuries. In the diagnosis and treatment of patients with CTFSB should participate resuscitator, maxillofacial surgeon, neurosurgeon, ophthalmologist, and otolaryngologist. Primary debridement of wounds, reduction and fixation of bone fragments in patients in compensated state should be done within 3 hours after injury, while at subcompensated state - during the first day, and at the decompensated state - within 3 days.
2. With the CT program "ADIL" can determine the overall condition of patients in a short time. The most informative diagnostic criteria arc the general condition of patients, level of consciousness, hemodynamic stability, shock index and temperature gradient. The severity of the general condition of patients is directly dependent on the localization of the fracture of the facial bones. Multiple fractures of the upper and middle areas of the face arc the most serious injury in patients.
3. Patients with CTFSB in compensated and subcompensated state emergency surgical aid and diagnostic procedures should be performed in full volume (maxillofacial surgery, traumatology, neurosurgery, surgery, ophthalmology and otorhinolaryngologist), including the reduction and fixation of bone fragments in the first day. To patients with CTFSB in state decompensated should be performed at least diagnostic procedures, limiting the amount of emergency surgery. Reduction and fixation of bone fragments should be done after the restoration of function of vital organs and systems.
4. The method of choice for the treatment of depressed large bone fragments of facial bones is a titanium distractor, the use of which gives a good clinical and functional outcome.
5. When depressed fracture of the zygomatic arch application of the developed device will allow us to produce reduction and fixation of bone fragments in the early stages (within one day) with a good cosmetic result.
6. At patients with CTFSB in posttraumatic period (7- 14th day.) there arc a deep depression of CD3, CD4 cell composition, humoral factors and secretory immune system, increased necrosis factor CD95, increasing the levels of proin-flammatory (IL-6 ) and a decrease - anti- inflammatory (IL -10) cytokines. On 9-10th day reduced total protein, calcium, potassium and phosphorus in the blood .
7. Reduction of cellular and humoral immunity, increased proinflammatory cytokine and tumor necrosis factor, reducing the anti-inflammatory cytokine , the protein concentration in the blood, calcium, potassium and phosphorus arc predictors of complications.
8. Application of complex drug therapy within the 1-3 days after the injury with the inclusion of immune ( immunomoduline, ribomunil ), enzyme ( Voben-zym ) drugs osteoplastic materials allows to correct the violation of homeostasis, also used to prevent complications.

In many aspects, the processes of regulation of the effects of opioid peptides remain unclear, but it has been shown that, due to the activation of opiate receptors, regulatory cellular reactions are involved, as well as the inhibition of adenylate cyclase and the formation of adenosine monophosphate. As a result, an increase in the supply of potassium ions and some other processes are observed. Interacting primarily with delta and mu receptors, dalargin controls the processes of pain relief and eating behavior. Dalargin mediates its effects both in the gastric mucosa and in the myocardium. The drug stabilizes blood flow and lymph flow in the area of the defect, stimulates increased production of mucus and a number of prostaglandins, these factors contribute to the regeneration of the mucosa. Interacting with receptors in the myocardium, the level of cyclic adenosine monophosphate and specific proteases decreases in cardiomyocytes, the process of glycogenesis increases, the concentration of catecholamines in the general blood flow normalizes, which improves hemodynamics and heart rate. Thus, these factors lead to accelerated scar healing.
