HI, hypoxia-ischemia; HPLC, high-performance liquid chromatography; NMRS, nuclear magnetic resonance spectroscopy; P7, postnatal day 7; NAA, N-acetyl aspartate.
Brain extracts of ipsi- and contralateral hemispheres from P7 rats subjected to HI were analyzed using 1H-NMRS and HPLC. For more details, see Materials and methods. Results are presented as mean±s.e.m. P values are given in the four columns to the right: Si versus HIi=ipsilateral sham versus ipsilateral HI; Sc versus HIc=contralateral sham versus contralateral HI; Si versus Sc=ipsi- versus contralateral hemisphere in sham; HIi versus HIc=ipsi- versus contralateral hemisphere in HI. The near significant P values (<0.1) are given in numbers. *P<0.05, **P<0.01, ***P<0.001.
Indicates that the results are from 1H-NMRS.
