Renal Expression and Urinary Excretion of Na-K-2Cl Cotransporter in Obstructive Nephropathy

Table 2

Changes in the fractional excretion of H₂O (EF% H₂O), K (EF% K), Osm (EF% Osm), and Na (EF% Na) in Sham, BUO-1, BUO-2, and BUO-7 rats.

Values are presented as means ± SE. BUO: bilateral ureteral obstruction; BUO-1: 1 day after releasing of BUO; BUO-2: 2 days after releasing of BUO; BUO-7: 7 days after releasing of BUO; Sham: sham-operated rats. Statistical comparison between experimental groups was made by a standard unpaired t-test versus Sham; or one-way ANOVA plus Newman-Keuls versus Sham, versus BUO-1, versus BUO-2, and versus BUO-7.
