Tumor alkalization induced by single dose of BP detected by ³¹P MRS.

<p>Effects of BP administration on tumor extracellular pH measured by <i>in vivo</i> ³¹P MRS. Tumors had an average extracellular pH (pHe) of 6.68 ± 0.26 at 24 h before treatment and 7.1 ± 0.1 at 1 hour after treatment (8 g/l). Bars indicate SD. (*) indicate p < 0.05.
