The initiation temperature chemical reaction in the wave filtration combustion gases in the presence of heat sink
We consider a single-temperature model of filtration combustion of gases in an inert porous medium in a non-adiabatic formulation. The condition of the initiation of the chemical reaction is obtained by solving the problem of incomplete expending of insufficient component of the gas mixture at zero temperature gradient.

Variations of ground-level ozone in different region of Tajikistan
The change in the surface concentration of ozone in the desert Ayvadj in Dushanbe and in the village Ziddi was studied. It was found that for the same background ozone concentration of about 100 mg/m in Ayvadj observed emissions to 400 mg/m , and in the village Ziddi - dips to near zero. The diurnal variation of ozone in Dushanbe has a lower level, with a maximum in the middle of the day.

Key words: концентрация; озон; парниковые газы; суточный ход; concentration; carbon dioxide; greenhouse gases; diurnal variation.

The effect of paraffin gathering inhibitors on rheology properties of oil fields of Tajikistan
The paper presents the results of study of the effect of complex compositions based on amine salts of tar oils on paraffin gathering from oil and rheology properties of oil fields in Tajikistan. It is found that the entry of paraffin gathering inhibitors to an oil system can reduce the flow resistance, it facilitates and improves transportable properties of oil.

Myocardial cytoprotective therapy for acute myocardial infarction complicated by cardiogenic shock
The article presents data on efficacious use of the cytoprotectant Mexicor in the complex treatment of patients with acute myocardial infarction complicated by cardiogenic shock. It is proved that the use of Mexicor leads to accelerated recovery of the left ventricular contractile and systolic and diastolic function, thereby reducing an ischaemic zone, the duration of ST-segment displacement periods and so minimizing the process of mortality risk of these patients.

Key words: острый инфаркт миокарда; кардиогенный шок; Мексикор; acute myocardial infarction; cardiogenic shock; Mexicor.

Improved health outcomes calculous cholecystitis is combined with urolithiasis
The experience of treatment of calculous cholecystitis (СC) are combined with urinestone disease (USD) in patients is analyzed. Patients with CC combined with USD were divided into a control group (34), in which traditional methods of the treatment was used, and basic group (40) in the diagnosis and treatment of which have been used modern technology. In treatment of CC, combined with the USD, were used a laparoscope, remote lithotripter and contact lithotripter. This article proves advantage of their using in the treatment of patients with CC combined with USD, in comparison to traditional methods.

Key words: калькулёзный холецистит, сочетающийся с мочекаменной болезнью; лапароскопическая холецистэктомия; дистанционная литотрипсия; контактная уретеролитотрипсия; эндоскопическая папиллосфинктеротомия; calculous cholecystitis combined with stone disease; laparoscopic cholecystectomy; extracorporeal lithotripsy; contact ureterolithotripsy; papilosfinkterotomiya endoscopy.
