[Sulfanilamide binding and distribution in the liver cells of rats].

Experiments on white noninbred rats were made to study the binding by isolated organoids and distribution in liver cells of etazole, norsulfazole, sulfamonomethoxine and sulfalene. The latter drug was found to be absorbed by organoids to the greatest degree. Drug complexes with organoids were discovered to be capable of dissociating with a partial release of unbound drug. Intracellular distribution of sulfanilamides is marked by their accumulation primarily by the nuclei and to a lesser degree by the mitochondria and microsomes.
