Abstract: FIELD: medicine, otorhinolaryngology. 
     SUBSTANCE: the present innovation deals with treating diseases of the upper respiratory tract. One should detect disorders of mucociliary transport (MCT) due to measuring the motor parameters of ciliated epithelium cilia, at least, the rate of mucociliary transport that includes material sampling for further testing as ciliary epithelial cells and registration of cilia fluctuations in human respiratory tract due to TV microscopy performed in patient's lifetime. Material for testing should be sampled from mucosal surface of respiratory tract, and therapeutic tactics should be chosen depending upon motor velocity of cilium's tip obtained based upon mathematical modeling followed by calculations by the formula:  , where V c  - velocity of cilium's tip [mcm*sec 1 ]; C 1 , C 2 , α - calculated as average values being characteristic for every of human body states under investigation: healthy persons, patients with either acute or chronic forms of sinusitis by the developed model of cilia movement; C 1  - curvature of cilium's working length, constant being equal to 1/38 mcm -1 ; C 2  - cilium's curvature from its working length up to the tip [mcm -1 ]; α - cilium's inclination angle against vertical position [degrees]; π = 3.1417 - constant; L, T s  and T e  - parameters measured individually in every patient; L - cilium's length [mcm]; T s  - time from the onset of movement till maximal straightening of cilium's tip [sec]; T e  - time of efficient impact [sec]. Moreover, the value being V c  = 9.6 - 11.3 mm/min corresponds to normal MCT functioning. For patients with chronic purulent sinusitis beyond exacerbation accompanied with MCT disorder it is necessary to prescribe complex therapy: surgical or conservative therapy with preparations of secretolytic and secretomotory action. For patients with chronic purulent sinusitis beyond exacerbation without any MCT disorder one should prescribe surgical therapy. All patients with acute sinusitis with MCT disorder should be prescribed complex conservative therapy with preparations of secretolytic and secretomotory action. The method enables to specify optimal therapy based upon scientifically proved indications of investigations by taking into account individual peculiarities of every patient. 
     EFFECT: higher efficiency.

The method of a magnetic separation of the low-magnetic materials provides for: feeding of the separated material to the elongated ferromagnetic bodies inclined in respect to a vertical plane and mounted with a backlash and in parallel to each other; the further motion of the material along the elongated ferromagnetic bodies in the magnetic field, gradient of which acts in direction opposite to direction of gravity and depends on the geometric form and magnetic properties of the elongated ferromagnetic bodies; separation of the material in the magnetic field for magnetic and nonmagnetic fractions; drop under action of gravity of the nonmagnetic fraction of the material downwards through backlashes between the adjacent elongated ferromagnetic bodies; the further relocation of the magnetic fraction of the material along the elongated ferromagnetic bodies in a direction of its discharge at the outlet from the zone of action of the magnetic forces. Relocation of the separated material is conducted directly in the backlash between the elongated ferromagnetic bodies in the magnetic field, the magnetic displacement vector of which is directed at the right angle to the dilatational plane of symmetry of the adjacent elongated ferromagnetic bodies, which in whole or in part are the sources of the magnetic field for each pair of the adjacent elongated ferromagnetic bodies.

Each elongated ferromagnetic body or a part of it is made out of the permanent magnets being the sources of the magnetic field for each pair of adjacent elongated ferromagnetic bodies. The technical result: increased effectiveness of separation of the low-magnetic materials due to formation of a magnetic line barrier at most meeting the conditions of separation of the particular material. 
     EFFECT: the invention ensures increased effectiveness of separation of the low-magnetic materials due to formation of a magnetic line barrier at most meeting the conditions of separation of the particular material.
