title: [Utilization of magneto-biological effects in neurosurgery].
abstract: After referring to the application of magnetoes used until now for fixation of ferromagnetic substancies in aneurysms, the new results obtained with externally exployed magnetic fields are discussed. Target site is calculated according to stereotactic principles. In the magnetic field the circulating blood is influenced in such a manner, that in the anode region clotting will occure, wherease in the region of cathode the clotting will be inhibited. After developing the appropiate equipment, these conditions were studied  on the basis of experimentally produced aneurysms in thyroid arteries of animals as well as in 30 ptients. It is assumed, that magnetic fields increase the immunoresistance of the organism and also exert a direct influence on the growth of tumourcells.
