The method of determination of acrylamide in various food (milk powder, potato chips, instant coffee) by gas-liquid chromatography after pre-bromination was developed. Studies have shown the possibility of using bromination of acrylamide to give it the necessary properties for better extraction, purification and detection. Also revealed the possibility of qualitative and quantitative determine a acrylamide in food by gas-liquid chromatography with detection by electron capture detector.

The extraction of mycotoxins was carried out by small volumes of solvents (water/aceton/hexane) without additional sample clean up and concentration. The extracts were analysed by HPLC using mixture of methanol/ethylacetate/phosphoric acid, pH 2.

A study of 425 patients demonstrated that a pyodestructive process, located anywhere, affects platelet functional properties, resulting in the first place, in disorders of spontaneous cell disaggregation. Impaired platelet functional properties are conducive to the development of postoperative purulent and thromboembolic complications.

As was shown by analysing the results for a sample from 100 cells, the property varied within a wide range which exceeded several times the error of a single measurement.

The influence of interlok, biotop and remantadine on the functional activity of monocytes was determined with the use of the NBT test permitting the quantitative evaluation of this characteristic. In this study interlok was found to give promising results in the treatment of acute viral hepatitis, due both to its antiviral action and to the stimulation of the functional activity of monocytes. biotop proved to render a sharply pronounced stimulating effect on the functional activity of monocytes, thus enhancing antiviral resistance.
