ABSTRACT
BACKGROUND AND OBJECTIVES:
A typical side effect of super high magnetic field is dizziness and it is expected that 7 Tesla (T) super high magnetic field will have temporary influence on vestibular nucleus. Prevalence rate of dizziness generally increases with advancing years, so this study discusses whether the influence of 7 T super high magnetic field differs depending on the age. MATERIALS ANDMETHODS:
C57BL/6 mice weighting from 10-40 g were categorized into 4-week-old and 16-week-old groups. They were exposed to 7 T magnetic field and immunohistochemical staining was done to observe expression of c-fos protein in vestibular nucleus of mice.RESULTS:
Control group with normal vestibular system did not show c-fos protein. However, mice exposed to 7 T magnetic field showed c-fos expression selectively on medial and lateral parts of vestibular nucleus and there was no significant difference of c-fos expression between both sides (p<0.05). There was statistically significant difference between the different age group 16-week-old mice group showed higher number of cells expressing c-fos protein than 4-week-old mice group did (p<0.05).CONCLUSION:
It is statistically significant that 7 T super high magnetic field is more influential to older age group.
