MRS measured cerebral intracellular pH and ratios of metabolites including ATP\/inorganic phosphate (Pi), phosphocreatine (PCr)\/Pi, N-acetyl aspartate (NAA)\/creatine (Cr), and lactate\/Cr before and during DKA treatment. We determined the effects of treatment with insulin and intravenous saline with or without bumetanide, an inhibitor of Na-K-2Cl cotransport, using ANCOVA with a 2 \u00d7 2 factorial study design.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>Cerebral intracellular pH was decreased during DKA compared with control (mean \u00b1 SE difference \u22120.13 \u00b1 0.03; P &amp;lt; 0.001), and lactate\/Cr was elevated (0.09 \u00b1 0.02; P &amp;lt; 0.001). DKA rats had lower ATP\/Pi and NAA\/Cr (\u22120.32 \u00b1 0.10, P = 0.003, and \u22120.14 \u00b1 0.04, P &amp;lt; 0.001, respectively) compared with controls, but PCr\/Pi was not significantly decreased. During 2-h treatment with insulin\/saline, ATP\/Pi, PCr\/Pi, and NAA\/Cr declined significantly despite an increase in intracellular pH. Bumetanide treatment increased ATP\/Pi and PCr\/Pi and ameliorated the declines in these values with insulin\/saline treatment.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>These data demonstrate that cerebral metabolism is significantly compromised during DKA and that further deterioration occurs during early DKA treatment\u2014consistent with possible effects of cerebral hypoperfusion and reperfusion injury.
