Abstract: FIELD: AIDS treatment. SUBSTANCE: method consists in liberating patient of various viruses, including, and first of all, AIDS producing retrovirus (HIV), cells contaminated by these viruses, and associated microorganisms by means of plasmasorption using individually prepared for each patient immunoadsorbents which are enhanced by covalently bound glucoprotein isolated from human placenta and manifesting elevated affinity to AIDS retrovirus. Blood purification procedure involves plasmophoresis directly after plasmosorption while simultaneously replenishing blood plasma with equal volume (1000-1200 ml) of plasma substitute in the form of rheopolyglucin and once more applying plasma sorption using fresh immunosorbent. Blood purification procedures alternate with applying specific immunostimulation using autovaccine prepared in each separate case on the basis of UV inactivated blood culture from given patient. In the late phases of AIDS development, blood purification and specific immunostimulation using autovaccine are performed via replenishment of macrophages and helper T cells damaged under AIDS conditions by way of intracostal transplantation of umbilical cord blood from umbilical cord cut off upon childbirth, in which all necessary stem cells-hemoleucopoesis precursors are present. EFFECT: facilitated blood purification procedure.

Abstract: Использование: сеялка предназначена для высева некоторых видов мелкосемянных овощных культур, в частности моркови, редиса, цикория. Область применения сеялки - фермерские, коллективные и мелкие крестьянские хозяйства, садово-огородные кооперативы. Сущность: преимущества предлагаемой конструкции в возможности производить посев как в шахматном, так и в рядном порядке. Для этого применен двухрядный дозатор, который, кроме шахматного посева, дает возможность значительно упростить конструкцию, т.к. не требуется ускоряющая передача с приводного колеса на вал дозатора. Для формирования бороздки применена лыжеобразная плита с фигурным гребнем. Приводное колесо дозатора расположено за плитой. Лыжеобразная плита предварительно заглаживает поверхность грунта, благодаря чему получается бороздка с ровным основанием и боковинами, а приводное колесо вращается равномерно и без проскальзывания. Для предотвращения раскатывания семян шаровидной формы после сброса применены П-образные хвостовики, а для уменьшения скорости сброса на концах сопл приемных кожухов имеются отсекатели, гасящие скорость падения семян. Применение сеялки предлагаемой конструкции позволит повысить производительность и качество посева, а при шахматном посеве дает возможность получить экономию посевной площади и повысить качество выращиваемых овощей. 5 ил.

Granted: 1998-04-27
Abstract: FIELD: mechanical engineering. SUBSTANCE: invention aims at improving quality of restoring tubular objects owing to reduced barrelness, formation of valleys on the surface of object, etc. When current passes through inducting wireway in the object clasped between end holders, currents are inducted. Inducting wireway consists of segments arranged at angle 90 deg. to each other, so inducted circular currents lye in two mutually perpendicular planes and direction of circular currents in one of them coincides with direction of generatrices of cylindrical surface of object. Such arrangement of circular currents results in more uniform heating of object and therefore in higher quality of restoration. EFFECT: improved restoration quality. 2 cl, 2 dwg
