The purpose of this study was to quantitatively
determine the influence of the time-dependent effects of
hypoxic-ischemic-encephalopathy (HIE) on cerebral
metabolite changes in a neonatal rat model of severe HIE.
Our results exhibited that a total of 16 metabolite
signals in HIE rats were significantly altered with
increased periods of development (at PD7, PD14, and
PD28), compared to the CNTL. The present study is unique
in that we discovered not only the usefulness of
traditional markers (NAA, Cr, and choline-containing-compounds)
but also several new results (Ala, Asp, Glu, Gln, and
GSH, etc.) from a neonatal rat model of severe HIE.
