Origin of so-called “Foam cell” of mammarygland are studied cytologically: Papanicolaou staining, May-Giemsa staining, Peroxydase reaction, Berline blue reaction, Test of phagocitic activity bycarbon particle method.
Results are as follows:
(1) 57.1% of foam cells are positive for Peroxydase reaction.
(2) 56.8% of foam cells include leucocytes asdegenerated shape in their cytoplasma.
(3) Almost all foam cells are positive for Berlinblue reaction.
(4) 79.0% of foam cells have distinct phagocitic activity by means of carbon particle method.
Peroxydase granule in cytoplasma of foam cellare recognized accompanied with degenerated leucocytes nuclei.
If, Peroxydase granules are only recognized incytoplasma without leucocytes nucleus, degeneratednuclei of leucocytes are found attached to the cyto-plasmic borders.
Carbon particles are found scattered by belongto the reticular structure of cytoplasma.
It may be said that the almost foam cells are origina ted by histiocytes.
