Description

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.<BR>Results are as follows:<BR>(1) 57.1% of foam cells are positive for Peroxydase reaction.<BR>(2) 56.8% of foam cells include leucocytes asdegenerated shape in their cytoplasma.<BR>(3) Almost all foam cells are positive for Berlinblue reaction.<BR>(4) 79.0% of foam cells have distinct phagocitic activity by means of carbon particle method.<BR>Peroxydase granule in cytoplasma of foam cellare recognized accompanied with degenerated leucocytes nuclei.<BR>If, Peroxydase granules are only recognized incytoplasma without leucocytes nucleus, degeneratednuclei of leucocytes are found attached to the cyto-plasmic borders.<BR>Carbon particles are found scattered by belongto the reticular structure of cytoplasma.<BR>It may be said that the almost foam cells are origina ted by histiocytes.
