title: Lung parenchyma response of rats stimulated with living pneumococci by respiratory way. A histologic, histochemical and electron microscopic study.
abstract: The pulmonary intralobular connective tissue of albino rats stimulated by a pulverized suspension of living pneumococci is the site of an abundant cell proliferation and pyronine-plasma cell reaction, having as molecular substratum enhanced activity of Alk-Ph-ase, ATP-ase, SDH-ase and LDH-ase. Cells in varying degree of plasmacytic differentiation were evidenced electron microscopically at alveolar wall level.
