Abstract：
Mn²⁺-enhanced magnetic resonance imaging is very useful for mapping the olfactory bulb,but has poor positional resolution(～100μm)and difficulty with the quantitative analysis of Mn.Synchrotron Radiation X-ray Fluorescence(beam size ～20μm,detect on limit of Mn ～10^－11g) and Energy Disperse X-ray Fluorescence combined with multi-variable statistics were employed to investigate the positional distribution of manganese and other elements in slices of the olfactory bulk of SD rats.The naris of rats were pipetted with MnCl₂ (Mn group n=4) compared with the control group (n=3).Our results show that the manganese distributions in the slices of both groups were non-homogeneous.The difference in the contents of Mn of rats treated with MnCl₂ is as high as 50 times.Rats treated with MnCl₂ exhibited a strong correlation (0.985,p=0.000) between the positional distribution of Mn and Ca,and the contents of Mn,Ca,Zn and Br of the Mn group were 55%,82%,42% and 72% higher than the control group.
