in the present studies we have examined the effects of in vitro addition of d-aldosterone to isolated tubules , as well as the effects of triamterene and spirolactone . d-aldosterone ( 0.2 mum added to the perfusate or 1 mum added to the bathing medium ) resulted in a marked stimulation of the transtubular potential difference ( lumen-negative ) after a short latent period . d-aldosterone had no effect on the potential difference of distal convoluted tubules of intact or adrenalectomized rabbits .
