since antinatriuretic responses and the decrease in bicarbonate excretion response to rns were significantly decreased by blockade of bicarbonate reabsorption ( with acetazolamide and intrarenal sodium bicarbonate infusion ) , antinatriuresis during rns is partly mediated by a mechanism dependent on intact bicarbonate reabsorption .
