For this purpose, we used a multicentre diet, locally calledthe regional basic diet (DBR) and 60 male Wistar rats, treated from weaning with: (i) control diet, by theAmerican Institute of Nutrition (AIN); ii) DBR supplemented with low Na + content (0.06%), the DBRgroup; (iii) DBR supplemented with normal Na + content (0.3%), the DBRnorm group; iv) DBRsupplemented with high Na + content (3.12%), the DBRhiper group. The excretion capacity in relation tosodium intake was similar between these two groups (99.01 ¡À 0.12 vs 99.02 ¡À 0.17%).
