Abstract
Energy metabolites in rat brain under the same level of hypoxia were m onitored by P-31 NMR in both horizontal and vertical magnets. The chan ges in PCr, P-i, and pHi in the vertical setting toward the end of hyp oxia were significantly larger and the recovery in the horizontally he ld animals was more complete. The results demonstrated quantitatively that the stress of the alignment is superimposed on the stress of hypo xia in the vertical magnet.
