For this purpose allele version of IL28B gene is identified and immunological assay is carried out. In case of presence of allele rs12979860CC/rs8099917TT immunoprediction coefficient 1 (IPC-1) is calculated by formula: IPC-1=2.774-0.833*[CD3+]-0.016*[CD4+]-0.063*[CD8+]-0.525*[CD19+], where [CD3+] is absolute content of CD3+ cells in 1 l of blood, [CD4+] is absolute content of CD3+/CD4+ cells in 1 l of blood, [CD8+] is absolute content of CD3+/CD8+ cells in 1 l of blood, [CD19+] is absolute content of CD19+ cells in 1 l of blood. If IPC-1 value is ≤1,5 development of fast virological response to standard therapy is predicted, in case of IPC-1>1.5 - its absence. If any other allele version is present IPC-2 is calculated by formula: IPC-2=3.994+0.014*[CD56+/ki-67+]-0.408*[CD25hi]-0.69*[CD25hi/FoxP3+], where [CD56+/ki-67+] is % of CD16+/CD56+/ki-67+ cells among blood lymphocytes, [CD25hi] is % of CD3+/CD25high cells among blood lymphocytes, [CD25hi/FoxP3+] is % of CD3+/CD25high/FoxP3+ cells among blood lymphocytes. If IPC-2 value is ≤3.0, fast development of fast virological response to standard therapy is predicted, in case of IPC-2 value >3.0 - its absence. |

Invention relates to veterinary and can be applied for reduction of toxic effect of enrofloxacin on opsonophagocytic activity of neutrophils with application of homeopathic preparations in vitro. For this purpose 0.15 ml of antibacterial preparation enrofloxacin 5% are added to leukocyte suspension in volume 0,5 ml. After that obtained solution is placed into thermostat for 3 hours at T=37±0.5°C, after incubation 0.5 ml of homeopathic preparation, diluted in physiological solution in selected dilution C6, C12, C30, C200. After that test-tubes are placed back into thermostat for 4 hours at T=37±0.5°C, after which suspension of microorganisms of reference strain Staphylococcus albus No 182 is introduced into each test-tube in dose 0.5 ml, containing 108 CFU in 1 ml of physiological solution, with the following placement into thermostat for 30 min at T=37±0.5°C, after incubation blood smears are fixed in alcohol-formalin 1:9, 40% solution of formalin and 96° alcohol, for 10 minutes and Romanowsky-Giemsa stained for 30 minutes. |

Invention relates to investigation of properties of a substance with optical means and a Raman scatter analyser. The analyser includes an optical beam splitter, an atomic vapour filter, a chopper and a photodetector. The beam splitter splits light emitted by a Raman scatter cell into two beams. The atomic vapour filter removes the Raman scatter line from the first beam. The chopper periodically interrupts the first and second beam directed towards the photodetector, which converts light from the first and second beams into an electrical signal. |

Measuring method of concentration of aerosol particles, and device for its implementation Proposed method allows measurement of distribution as to sizes and concentration of solid and liquid particles of aerosol at the interval of particle sizes: from 0.8 mcm to 2 mcm, from 2 mcm to 5 mcm, from 5 mcm to 10 mcm and more than 10 mcm by means of semiconductor conductometric sensors as per change of conductivity. At application of the proposed method for measuring concentration of aerosol particles in real time and the device for its implementation, which involves sampling from environment, distribution as to dispersion of the test flow of aerosol as to the corresponding chambers and measurement of aerosol concentration in each chamber, measurements are made by means of semiconductor conductometric sensors as per change of their conductivity after pre-heating, for that purpose, pre-calibration of sensors as per their conductivity on atmospheric air and on air containing aerosol with known concentration and dispersion, which is accepted as constant up to the end of measurements, with that, calibration is performed for each sensor, then, considering calibration, values of conductivities as per the specified algorithm are recalculated in concentration. |

Method for immunohistochemical colouring of whole amounts of biological tissue samples (versions) Group of inventions relates to experimental biology and medicine for preparing whole amounts of biological tissues for optical projection tomography, confocal, multi-photonic and plane optical microscopy and can be used for preclinical tests of pharmacological preparations and evaluation of physiological effects on the body, as well as for working with biopsy material for diagnostic and research purposes. A method for immunohistochemical colouring of whole amounts of biological tissue samples includes fixing tissue with paraformaldehyde solution. The method also includes postfixation, which is first carried out with 0.5-1% paraformaldehyde for 48 hours at 4°C, and then after washing three times with a phosphate buffer at room temperature, in a solution of 20% dimethylsulphoxide in 100% methanol for 1-2 hours at room temperature. The tissue sample is then bleached in a solution with the ratio 100% methanol:dimethylsulphoxide:30% H2O2=4:1:1, for 2-4 hours in bright light at room temperature until complete discolouration. The sample is then washed 3 times for 60 minutes each in 100% methanol at room temperature and frozen for at least 1 hour at -70…-80°C, and then rehydrated successively in 50, 25 and 12.5% methanol solutions in a phosphate buffer for 45-60 minutes each at room temperature. The samples are then washed three times from methanol with phosphate buffer, two times for 1-2 hours each at room temperature, and then the last time for one night at 4°C. Subsequent permeabilisation of the sample is carried out in phosphate buffer containing 2% Triton X-100, 5% normal serum, 5% dimethylsulphoxide, for 2 hours at room temperature. The sample is then washed three times in phosphate buffer containing 0.2% Triton X-100, twice for 30-60 minutes each at room temperature and the last time for one night at 4°C. The sample then undergoes incubation successively in primary and secondary antibody solutions prepared on a buffer which consists of 0.05 M Tris-HCl with pH 7.5; 0.15 M NaCl; 0.2% Triton X-100, 5% dimethylsulphoxide and 2.5-5.0% normal serum of the host of the secondary antibodies, at 4°C for 2-7 days, while washing after each incubation in a buffer consisting of 0.05 M Tris-HCl with pH 7.5; 0.15 M NaCl; 0.2% Triton X-100, first 3 times of 60 minutes each at room temperature, and then for one night at 4°C. The coloured samples are dehydrated successively in 50, 96% ethanol solutions in phosphate buffer for 45-60 minutes each at room temperature. The samples are then held first in 100% ethanol at room temperature 2-3 times for 45-60 minutes each, and then in 2-butoxyethanol at 4°C for 12-18 hours. The dehydrated samples are brightened at room temperature in a mixture of benzyl benzoate and benzyl alcohol, taken in ratio of 2:1, for 3-4 hours. The colouring method, starting from the postfixation procedure, is carried out while mixing at a rate of 650-800 rpm. A second version of the method includes carrying out incubation in a solution of fluorescent labelled primary antibodies, which are prepared on a buffer consisting of 0.05 M Tris-HCl with pH 7.5; 0.15 M NaCl; 0.2% Triton X-100, 5% dimethylsulphoxide and 2.5-5.0% normal serum, at 4°C for 2-7 days. |

Total native DNA is recovered from skin and hair samples; that is followed by carrying out a polymerase chain reaction and amplification of 5.8S rRNA gene fragment of Trichophyton mentagrophytes with using specific primers. If the electrophoresis procedure enables an amplification product of 182 base pairs in size being detected, the agent is considered to be found. |

Method of life-time diagnostics of tuberculosis Invention relates to an immunological diagnostics of diseases of cattle (cattle) in the common complex of antituberculous measures. The life-time diagnostics of tuberculosis is carried out, which comprises the determining of induced luminal-dependent chemiluminescence in serum from cattle reacting positively to PPD-tuberculin. The main inductor is used as inactivated BCG vaccine. Carrying out the diagnostics enables to eliminate non-specific reactions to PPD-tuberculin in cattle in tuberculosis-satisfactory estations. |
