[Cellular contacts and "cytoplasmic bridges" in the inflammation focus (scanning and transmission electron microscopic study)].

Contacts between cells in an inflammation focus were studied by the methods of scanning (raster) and transmission electron microscopy on a model of aseptic inflammation in the subcutaneous connective tissue in rats. It is shown that contacts among the cells of the connective tissue and the blood in the form of "cytoplasmatic bridges", observed in the scanning electron microscope, were not confirmed by the studies in the transmission microscope. The investigation of the "cytoplasmatic bridges" in the transmission electron microscope revealed a close adjacence of the cytolemma of the contacting cells, or a harrow space between them as wide as 10-30 micron.
