    • n dialysis In anatomy, separation of parts in general; dissolution of continuity of parts previously united.
    • n dialysis In medicine, loss of strength; weakness of the limbs.
    • n dialysis In chem., the act or process of separating the soluble crystalloid substances in a mixture from the colloid, depending on the principle that soluble crystalloid bodies will diffuse readily through a moist membrane, while colloids diffuse very slowly, if at all. This is done by pouring a mixed solution of crystalloid and colloid on a sheet of parchment-paper stretched over a wooden or gutta-percha hoop, having its edges well drawn up and confined by an outer rim. The parchment is allowed to float in a basin of water. Diffusion immediately commences, the crystalloid passing through and dissolving in the water beneath, while the colloid remains behind. Thus, gruel or broth containing a very little arsenic dissolved in it gives up the whole of its arsenic to the water, while scarcely a trace of the organic substance passes through. As almost all the poisons in common use —arsenic, corrosive sublimate, oxalic acid, lead acetate, morphia, and salts of strychnine, etc.—are crystalloids, the toxicologist is by this process furnished with an easy mode of detecting their presence, if they are in a form readily soluble in water.
    • n dialysis [capitalized] [NL.] A genus of dipterous insects.
    • n dialysis In botany, the separation of parts normally united, especially the parts of a whorl.
