Quantification of trace elements in the brain of SIDS victims.

摘要

In this report, the quantification and analysis of trace elements in the frontal lobes of the brains of sudden infant death syndrome (SIDS) cases were carried out. In all materials, V, Cr, Sn and Sb were not observed and Mg, Na, K, Fe, Zn and Br were observed. As for all of these trace elements, there was no significant difference between SIDS and non-SIDS. Only Ca was not observed in SIDS and observed only in non-SIDS. It is well known that Ca moves from outside of cells to inside of cells and induces cell damage by membrane disturbance in a hypoxic situation. The result in this report suggests that the deaths in SIDS cases are so sudden and are not sufficient for the kinetics of Ca into brain cells in the hypoxic situation.
