Parameters of relative peak areas and intracellular pH were accurately distinguished among the different causes of graft dysfunction. Ureteral obstruction was clearly identified by elevations in the phosphodiester\/urine phosphate peak. Ischemia and rejection were. both associated with increases in inorganic phosphates and phosphomonesters and decreases in the \u03b2\u2010phosphate peak of adenosine triphosphate but were distinguishable from each other by differences in intracellular pH which was normal in rejected allografts (7.33 \u00b1 0.07, <jats:italic>n<\/jats:italic> = 3) but low in ischemic allografts (7.00 \u00b1 0.05, <jats:italic>n<\/jats:italic> = 3, <jats:italic>P<\/jats:italic> &lt; 0.05). Grafts insulted with cyclosporine toxicity were not distinguishable from normal allografts by any of the parameters studied. These data suggest that <jats:sup>31<\/jats:sup>P NMR spectroscopy may have potential clinical application in differentiating among the causes of graft failure of human rend allografts. \u00a9 1987 Academic Press, Inc.<\/jats:p>","DOI":"10.1002\/mrm.1910050405","type":"journal-article","created":{"date-parts":[[2007,3,5]],"date-time":"2007-03-05T07:06:41Z","timestamp":1173078401000},"page":"346-352","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["<sup>31<\/sup>P nuclear magnetic resonance study of acute renal dysfunction in rat kidney transplants"],"prefix":"10.1002","volume":"5","author":[{"given":"J.
