Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medicine, specifically to ophthalmology. To form a filtration pad in fistulizing antiglaucoma intervention, local peritomy, conjunctival and tenon capsule separation are performed, formation of scleral flap, internal fistula, suturing on scleral flap and formation of filtration pad. Local peritomy is 4–5 mm long. Conjunctival and tenon capsules are separated in the direction of the arch by a blunt method. Filtration pad is formed by repositioning these tissues to the initial position, and applying submerged corneal-sclero-conjunctival sutures using an atraumatic bent needle with a cutting edge and nylon 10–0 unabsorbed by the filament, performing a needle sticking in cornea at 1/3 of its thickness at distance of 0.5 mm at the edge of the incision to the centre of the limb and withdrawing it through the sclera directly on the other side of the limb, simultaneously placing a conjunctiva and tenon capsule tissue on a needle, applying 2-3 helical loops and then changing the needle direction, puncturing it in the direction from the inside to the outside in sclera by 1/3 of its thickness and then into the cornea at distance of 0.5–1.0 mm from the limb, tightening and fixing the seam with three interrupted sutures. Three loops of the first assembly are tightened; the suture is finally fixed with two subsequent nodes. Threads are cut off and the node is immersed into the transparent corneal layers by the tweezers. At the second stage from the other edge of the incision, conjunctival and tenon capsule tissues are fixed in the same way, removing both cornea-sclero-conjunctival sutures two weeks after the operation using a pull-in forceps and a blade, crossing the filament lying on the cornea in the direction from the cornea and removing all through the cornea with the knot outwards. 
     EFFECT: method minimizes traumatic effect on tissues during tissue incision and separation, with application of fixing sutures, minimizes response inflammatory reaction, makes it possible to carry out in postoperative period, if necessary, such manipulations as laser suturolysis, needling in order to achieve maximum functional result.

Abstract: FIELD: enrichment of minerals. 
     SUBSTANCE: invention relates to a method and apparatus for extracting fine gold from clayey gold-bearing rocks. Device for vacuum disintegration of gold-bearing clay rocks includes working chamber and receiver, volume ratio of which is <1:200, vacuum pump performance ≥0.5 m 3 /s, connected to the receiver, fast acting pneumatic valves and pumping lapping atmosphere. Working chamber comprises a clay rock tray which is equipped with a heater with adjustable power of up to 200 W and three temperature sensors, made with possibility of installation at different depth of rock thickness. Pulse rate evacuation is carried out for not more than 1 s with pressure in working chamber of 0.4 kPa and subsequent reduction to 13 Pa for not more than 10 s at operating vacuum pump. Clay rock in the form of a flat layer with thickness of 1–5 cm is placed in a tray for clay rock and held at vacuum for 20 s, then during 20 s, the atmosphere is introduced, followed by holding at atmospheric pressure for 20 s. Pumping-admission cycle is repeated until rock freezes, which occurs during evacuation due to intensive evaporation of moisture from rock, after which for 10 minutes the heater is defrosted and temperature is raised to room temperature. Process of freezing-heating is repeated until the remaining amount of moisture becomes insufficient for freezing of the rock, at that, from 2 to 10 pumping-let-down cycles are performed. 
     EFFECT: invention enables to intensify the process and increase the efficiency of gold-containing clay rocks disintegration.

Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to obstetrics and pathological physiology, and can be used for prediction of risk of threatening interruption of early pregnancy accompanying exacerbation of cytomegalovirus infection. Women in blood serum are examined for VEGF-1 in ng/ml by enzyme immunoassay and docosahexaenoic acid (DHA) content in % by gas-liquid chromatography. That is followed by predicting the development of a risk of early termination of the risk of the exacerbation of cytomegaloviral infection by the prognostic index PI: PI = −62.735−0.809 × VEGF-1 + 9.845 × DHA, where PI is a discriminant function with boundary value of (−15.781). If the PI is equal to or greater than the boundary value, a risk of a threatening early miscarriage in the aggravated cytomegaloviral infection is predicted. If the PI is less than the limit value, the absence of a risk of threatening early miscarriage at the exacerbation of cytomegaloviral infection is predicted. 
     EFFECT: method enables higher accuracy of prediction of miscarriage in aggravated early cytomegaloviral infection by determining VEGF-1 values and docosahexaenoic acid in blood serum of pregnant women with the detected cytomegaloviral infection, prognostic index of PI, relative to which limit value of discriminant function is predicted threatening interruption of early pregnancy with exacerbation of cytomegalovirus infection.
