Effect of elevated NaCl intake on albuminuria in sham, remote/contralateral acute kidney injury (AKI), and direct/ipsilateral AKI groups. Albumin excretion rates were derived from 24-h urine collections at the indicated times. Data for day 63 time points were not obtained due to the need to collect blood pressure measurements. Data are means ± SE. *P < 0.05 vs. sham-operated control by ANOVA and Student-Newman-Keuls post hoc test. (a, b)Significant increases in sham-operated and remote injury groups following exposure to elevated NaCl relative to the final collection under standard salt conditions (i.e., day 33).
