["Fenaf"--a new histochemical stain]

The authors have synthesized a new dye which by its histochemical properties is analogous to the imported aldehyde-fuchsin but much cheaper. The production of this dye under the trade name "Fenaf" is organized at Shostka's factory of chemicals. The dye reveals neurosecretion, thyrothrophocytes of the adenohypophysis, tissue mast cells and other structures that are stained with aldehyde-fuchsin.
