[Determination of polioksin B in the air environment and in washouts from skin of operators by HPLC].

Polyoxin B being an effective inhibitor of synthesis of chitin of the cell wall of many phytopathogenic fungi, is recommended as a fungicide for control of phytopathogenic organisms that cause damage to crop. For the determination of the exposure of employees working with pesticides there was developed the method of the measurement of concentrations of polyoxin B in air of working area, atmospheric air of populated areas and washouts from the operators ’ integuments, based on high performance liquid chromatography with ultraviolet detector (detection wavelength of270 nm), including sampling air environment in the sorption tube ORBO-44, filled with sorbent XAD-2, extraction of the sorbent with polyoxin by a mixture of carbinol-water (in a ratio of 95:5,on volume), washout from the surface of the skin with ethyl alcohol by way of washing, concentrating, quantitative chromatographic analysis. Lower limits of the quantification ofpolyoxin B in the air ofworking area - 0.

[The method of multicomponent determination of herbicides of various chemical classes in water].

In the work there are considered results of the development of the multicomponent method of measurement of concentration of herbicides of various chemical nature under their joint presence in the water. There was justified the optimality of application of HPLC-DAD (the working wavelength of 240 nm) for the determination of levels of 10 active ingredients of herbicides of class of sulfonylurea (metsulfuron-methyl, nikosulfuron, sulfometuron-methyl, thifensulfuron-methyl, triflusulfuron-methyl), imidazolinone (imazapyr, imazethapyr), 2,6-Bis[(4,6-dimethoxy-2- pyrimidinyl)oxy]benzoic acid (bispyribac acid), triazol-pyrimidines (Penoxsulam), a benzoylpyrazole compound (Topramenzone). For the concentrating and cleaning of samples of water there were used cartridges for solid-phase extraction of Oasis HLB - the macro porous copolymer made on the basis of the balanced ratio of 2 monomers - lipophilic divinylbenzene and hydrophilic N-vinylpirrolidone.

[The efficacy of the ultrashort-term action insulin-lispro preparation "humalog" and the antioxidant mexidol in the complex treatment of type I diabetes in infants and adolescents].

Monitoring of a group of 96 children with type I diabetes mellitus showed the positive effect of fast-acting insulin analog humalog on the long-term glycemic control and correction of metabolic disturbances in the vegetative nervous system and on the elimination of psychological problems. Additional prescription of the antioxidant drug mexidol promoted restoration of the cardiac rhythm variability, normalization of a daily structure of the heart rate, improvement of memory and attention and decreased the level of anxiety. The observations showed a decrease in the rate of formation of the diabetic cardiac neuropathy and a reduction of expressiveness of cerebroasthenic syndrome.

[The morphofunctional status of the hypothalamo-hypophyseal neurosecretory system and the energy processes in the gastric tissues following electromagnetic irradiation in the millimeter wave range].

A single and double 15 and 30 min exposure to electromagnetic waves of millimetric range (60 GGz, 3 mW/cm2) of a biological active point (acupuncture point) EIII36 of intact male rats and those subjected to stress inhibits the functional activity of hypothalamo-hypophysis neurosecretory system, thyroid gland and cell elements of gastric glands the inhibition being mostly pronounced in animals under stress.
