[Morphological features of milky spots of the rat omentum in inflammation].
The omental milky sports of the rat have been examined with the light and electron microscope after intraperitoneal stimulation by particulate coal and zymosan. No positive correlation between cell level proliferation in milky spots and alteration of their size has been found. The increase in size of milky spots is due to the inflow of cells from the blood and bone marrow. The development in milky spots of a great number of macrophages "tubercles" and multinucleated giant cells in the experimental conditions may respond to inflammation. The administration of zymosan result in the influx of lymphocytes forming lymphatic follicle-like structure. Despite the absence of germinative centres, the appearance of a great number of lymphoblasts and plasma cells in the milky spots provides the evidence of the active antibody production aimed at immunological protection of abdominal cavity.
