Abstract In order to demonstrate the localization of an anti-allergic agent, Tranilast, in the mast cells, light microscopic radioautography was performed. The mast cells collected from rat peritoneal cavity were incubated for 0 to 60 min in a medium containing 3H-Tranilast. After the incubation, they were fixed, embedded and processed for light microscopic radioautography. The radioautographic silver grains were frequently localized around and over the cytoplasmic granules and their number increased according to the prolongation of incubation time. From the results obtained at present it was demonstrated that Tranilast was rapidly taken into the cytoplasm of mast cells. This phenomenon may suggest an important role of this agent in the inhibition of allergic reactions of mast cells.
