To
investigate the essential intrarenal electrolyte gradients in early diabetic
kidneys, hyperpolarized 13C urea was applied to measure urea and sodium
gradients. No differences in either intrarenal urea or sodium gradients were
observed in early diabetes compared to healthy controls. These results indicate
that the early metabolic and hypertrophic changes occurring in the diabetic
kidney prelude the later functional alterations in diabetic kidney function,
thus driving the increased metabolic demand commonly occurring in the diabetic
kidney.
