smooth muscle cells of the guinea-pig vas deferens after cl- depletion actively reaccumulate ions to a level many times higher than that predicted by a passive distribution , even when anion exchange ( largely responsible for cl- movements in this preparation ) is inhibited by dids ( 4,4'-diisothiocyanostilbene-2,2'-disulphonic acid ) .
