[Studies on distribution of magnetic-bearing microspheres in rabbits].
OBJECTIVE
To evaluate the distribution of magnetic-bearing microspheres (MPMs) in rabbits.


METHODS
The distribution of intravenously injected 99mTc-labelled MPMs in rabbits at different intervals of magnetic field applied and different magnetic field intensity was investigated by using an externally applied magnetic field and measuring the radio-activity at the rabbit head and other organs.


RESULTS
MPMs have the properties of targeted distribution, as positive correlation between targetic radio-activity and times and intensity of magnetic field.


CONCLUSIONS
MPMs may be better used in the therapy of cavernous hemangiomas.
