Abstract: FIELD: chemistry; pharmacology. 
     SUBSTANCE: invention relates to biochemistry and pharmacology, and can be used for quantitative measurement of antiproliferative activity of interferon-beta preparations. Method for quantitative determination of antiproliferative activity of interferon-beta with respect to tumour cells involves cultivation of tumour cells in the presence of interferon-beta with further determination of the content of living cells. Cultivation of tumour cells with interferon-beta is carried out in the presence of human effector cells, such as human peripheral blood mononuclear cells. Tumour cells are human adenocarcinoma cells HT-29. Human peripheral blood mononuclear cells are used in quantitative ratio within 5:1–10:1 in relation to tumour cells. Tumour cells are cultured in the presence of human peripheral blood mononuclear cells 4 to 8 days, preferably for 5 days. 
     EFFECT: technical result is quantitative evaluation of antiproliferative activity of interferon-beta in relation to tumour cells, including in insufficiently expressed direct action of interferon-beta on tumour or its complete absence.

Abstract: FIELD: physics. 
     SUBSTANCE: invention relates to navigation, including radio navigation, and can be used to determine spatial coordinates (SC) of stationary or mobile radio object (RO). Method is characterized by that r/s with individual features are generated and transmitted by a ground pontoon radio engineering system (PRES), comprising at least four ordered numbered points, coordinates of phase centres of antennae (PCA) of which are known on the RO. Besides, r/s is received and identified for each point on ground control station (CS) with moving antenna (MA), which is moved so that its phase centre (PC) moves along the specified circular trajectory with the specified angular speed. At fixed position of PC MA, spectrum frequency deviation (FSD) of received r/s from its specified position is measured for each point. When the antenna is moved, the projections of the movement speed of the PC MA are transmitted to the straight lines connecting the PC MA with the PCA of the points corresponding to the accelerations thereof, derivatives of these accelerations in time and from these projections and specified angular velocity determine time-varying passing times of r/s from PC MA to PCA of points in compliance with proposed equation of measurement. This information is transmitted to corresponding points, where information on FSD and time shifts are used, respectively, for frequency adjustment at each point and for general synchronization transmitted by all points of r/s. When receiving and identifying radio signals on the RO, relative ranges from the PCA RO to the PCA are determined, and from them and the well-known coordinates of the PCA of the PRES are unambiguously determined by the SC PCA RO. 
     EFFECT: technical result is absence, including requirements for availability of common time system for transmitting and receiving radio signals (r/s) objects.
