Abstract: FIELD: medicine.  
     SUBSTANCE: invention relates to medicine, namely biotechnology, immunology, implantology, and can be used to assess the suitability of synthetic polymers for medical purposes. A sample of peripheral venous blood is obtained from a volunteer, then it is centrifuged to obtain a population of mononuclear leukocytes. The resulting cell suspension is introduced into the wells of a round-bottom plate with samples of synthetic polymers placed in them in the form of a cylinder with a length of 3 mm and a diameter of 1 mm in the amount of 1 piece per well. The plate is incubated at 5% CO 2  for 72 hours at a temperature of 37°C. The number of mononuclear leukocytes and the concentration of anti-inflammatory cytokines IL-4 and IL-10 are determined, expressing the obtained indicators in the form of a stimulation index (SI), which is calculated by the formula: SI =SPP/SPG, having previously determined the specific production of each of the cytokines in the presence of a synthetic polymer (SPP, pg/k) and the specific production of each of the cytokines in the presence of glass (SPG, pg/kl) according to the formulas:  
     SPP = P/NL s ; SPG = G/NL g , where 
     P is the cytokine concentration in a sample with a synthetic polymer, pg/ml; 
     NL s  the number of mononuclear leukocytes in a sample with a synthetic polymer, in 1 ml; 
     G is the concentration of cytokine in a sample with a glass sample, pg/ml; 
     NL g  is the number of mononuclear leukocytes in a sample with glass, in 1 ml. The suitability of the use of synthetic polymers for medical purposes is evaluated. An SI value equal to or greater than 1 indicates the suitability of their use for medical purposes.  
     EFFECT: method provides increased efficiency, reduced time and labor costs, the possibility of simultaneous verification of a significant number of samples, a comprehensive assessment of the proliferative and cytokine-producing activity of mononuclear cells in direct contact with the samples, making it possible to determine the direction of the immune response, justifying the choice of a promising material for medicine, by implementing a contact method for exposure of cells of the immune system, mononuclear leukocytes contained in human peripheral venous blood to synthetic polymer samples, with an assessment of their production of anti-inflammatory cytokines  in vitro  according to the index of stimulation, which in a comparative analysis of the test results makes it possible to select the most promising samples.

Abstract: Die Erfindung betrifft eine Beschickungsanlage fuer Faesser mit radioaktivem Inhalt, wobei dieser in paketierter Form im Fass vorliegt und/oder einbetoniert werden kann, bestehend aus einer, mindestens teilweise in einer alphadichten Box arbeitenden Paketierpresse. Der besondere Vorteil der erfindungsgemaessen Beschickungsanlage besteht darin, dass die Abfaelle besonders innig mit dem Betonmantel verbunden werden und dass der Betonmantel praktisch gleichzeitig mit dem Paketiervorgang erzeugt wird. Durch ein Einbringen des Bodenblechs wird eine Verstaerkung des Fasses erzielt. Der Massezylinder bleibt weitgehend frei von Anbackungen durch Ueberziehen mit der Fettschicht. Das An- und Abkuppeln der Faesser mit radioaktiven Abfaellen kann somit weitgehendst kontaminationsfrei erfolgen. Die radioaktiven Abfaelle koennen genau in der Mittelachse des Fasses fixiert werden, so dass der sie umgebende Betonmantel einen gleichmaessig dicken und wirksamen Schutz  darstellt. Letztlich ist bei der Kompaktierung von Filtern oder sperrigem Material keine Handarbeit innerhalb der Box notwendig, da dieselben von ausserhalb der Box in das Fass einbringbar sind.                                                                                                                                                                                                                                                                                                                                         ...U.S.W

Abstract: Eine Ferroresonanz-Stromversorgungsschaltung, die eine relativ stabile Ausgangsspannung liefert, enthält ein Sättigungsmagnetelement mit einem magnetisierbaren Kern (20) und einer darauf befindlichen Wicklung (22). In der Wicklung wird ein Magnetisierungsstrom durch eine Quelle (23) hochfrequenter Eingangsspannung zur Erzeugung eines magnetischen Wechselflusses in dem magnetisierbaren Kern (20), welcher mit der Wicklung verkettet ist, hervorgerufen, so daß eine Ausgangsspannung wechselnder Polarität entsteht. Ein Kondensator (26) läßt einen zirkulierenden Strom entstehen, der einen magnetischen Fluß in einem Kernabschnitt hervorruft, welcher der Wicklung zugeordnet ist und zur magnetischen Sättigung des Kernabschnittes beiträgt, so daß die Ausgangswechselspannung infolge einer Ferroresonanzwirkung geregelt wird. Zur Temperaturstabilisierung der Ausgangsspannung wird der magnetische Sättigungskernabschnitt des magnetischen Elementes aus einem Ferrospinell gebildet, das ein Lithiumferrit oder ein substituiertes Lithiumferrit enthält.
