Abstract: FIELD: explosive works. 
     SUBSTANCE: invention is related to the field of mining industry, to methods of blast-hole drilling works performance in flooded wells with non-waterproof explosives. Method includes application of explosive charge from one or several cartridges of the same diameter, which are arranged in polymer waterproof coating and which contain non-waterproof explosive that is sensitive to pulse of primary facility of initiation with density of less than 1,000 kg/m 3 , which is separated with layer of inertial substance with density of more than 1,000 kg/m 3 , the length of which is determined by formula, with ratio of charge and well diameters - 0.7-0.9. Transfer of detonation to explosive via layer of inertial material in cartridge is executed with detonating cord, which is installed on the cartridge surface on sections of explosive substance, which are adjacent to the layer of inertial material, in the form of two strapping units, which consist of at least 2 coils of detonating cords that are connected between each other by linear section of detonating cord and are tightly fixed on the cartridge surface, or non-electrical detonators that are tightly fixed on the surface of explosive substance sections, which are adjacent to layer of inertial material, which are connected between each other by section of shock wave tube. At that charge initiation is carried out instantaneously or with deceleration by stationary explosion facilities. 
     EFFECT: reduction of explosive works cost, increase of rock crushing efficiency, improvement of environmental situation in the area of mass explosions performance.

     SUBSTANCE: invention relates to a method for isolating pectin from vegetable raw used for production of products of prophylactic and curative designation. Invention describes a method for preparing pectin. Method involves treatment of preliminary milled vegetable raw, for example, dried sunflower heads with a mixture of chloroform and ethanol followed by extraction in water bath at 70-80°C for 30-40 min, filtration and separation of the first extract. Filtered off vegetable raw is poured with distilled water at temperature 60-70°C and extracted in water bath at temperature 90-95°C for 1 h followed by filtration and separation of the second extract. Filtered off vegetable raw is poured with 0.3-0.5% ammonium oxalate solution, extracted in water bath at temperature 75-80°C for 30-40 min, filtered and the third extract is separated. Filtered off vegetable raw is poured with a 0.4-0.5% hydrochloric acid solution, heated at temperature 75-80°C for 1 h followed by filtration and separation of the fourth extract that is mixed with prepared first, second and third extracts. Prepared solution is neutralized with ammonium hydroxide to pH 7 and precipitated with 96% ethyl alcohol, precipitate is squeezed our and dried at temperature 4-6°C. Proposed method provides increasing yield of pectin and its solubility. 
     EFFECT: improved preparing method.

     SUBSTANCE: method comprises determination of IgG-antibodies level in blood plasma before and after treatment. For this purpose content of specific IgG-antibodies to herpes simplex virus of I and II type in patient's blood is determined before treatment and on 7 th , 14 th , and 21 st  days after treatment at the remission stage; also the degree of IgG-antibodies' avidity and level of circulating immune complexes (CIC) is evaluated. If the content of specific IgG-antibodies increases no less than 27% in 7 days after treatment, in 14 days - no less than 33%, and in 21 days - no less than 60% compared to initial level; if degree of specific IgG-antibodies avidity compared to initial level increases no less than 25% in 7 days, in 14 days - no less than 38%, and degree of avidity subsequently increases, or remains constant, or reduces no more than 6% in 21 days compared to previous period (14 days); and if CIC content increases no less than 27% in 7 days compared to initial value, in 14 days - no less than 36%, and content of CIC reduces no more than 23% in 21 days compared to previous period (14 days) in cases with initial content of CIC $ 150 arbitrary units, or content of CIC reduces no more than 37% in 7 days compared to initial value, in 14 days - no more than 43%; in 21 days increases no less than 6% compared to previous period (14 days) in cases with initial content of CIC > 150 arbitrary units - then conclusions can be drawn that the treatment was effective and prognosis for clinical course is favourable.
