[Ultrastructural changes in neutrophils and anaerobic microorganisms during their interactions in experimental acute intestinal obstruction].

The authors established that 12 h after development of acute obstructive ileus in inactive neutrophil granulocytes (NG), the anaerobic microorganisms were intact, or at the process of division; in the active NG, they were destroyed, or when forming "halo", might preserve and migrate in the matrix of NG. In interaction of NG with microorganisms, the numerous oval and roundish bacterial bodies with a diameter of 0.2-0.5 micron capable to penetrate into the non-phagocytic cells are formed. A function of the formations revealed is not studied.
