- 摘要：
PROBLEM TO BE SOLVED: To provide a magnetic particle-containing raw medicine for medicines, which enables the production of the magnetic particle-containing diagnostic and therapeutic medicines capable of exhibiting homogeneous functions in good repeatability.
SOLUTION: This magnetic particle-containing raw medicine for the medicines is characterized by being a colloid aseptic aqueous solution in which magnetic ion oxide fine particles having an average particle diameter of 5 to 30 nm, saturation magnetization of 50 to 90 Am
2 /kg and a coercive force of 0 to 1.6 kA/m are mono-dispersed. The magnetic particle-containing raw medicine for the medicines can be obtained by producing fine magnetic iron oxide particles, washing off water-soluble by-produced salts by-produced in the reaction time from the reaction solution by a conventional method to purify the colloid aqueous solution of the superparamagnetic iron oxide particles, and then replacing the dispersion medium of the purified colloid aqueous solution by superpure water.COPYRIGHT: (C)2006,JPO&NCIPI
