[Effect of prodigiozan on the surface structures of peritoneal macrophages under the scanning electron microscope].

The surface structures of peritoneal macrophages of mice were investigated with a scanning electron microscope RZEM-500. The study revealed 3 types of the macrophages. Macrophages of type 1 predominated in intact mice. These macrophages are cells rounded or oval in shape with a great number of compact finger-like excresences differing in size and form. In the animals treated with prodigiozan in a single dose of 150 mg/kg, the majority of the macrophages were larger in size and had a changed surface: spread, with many branches, "train", undulated membranes. Formation of a great number of macrophagal and macrophagal-lymphocytic clusters evident of the increased cell cooperation under the effect of prodigiozan was shown. The morphological changes in the surface structures of the macrophages under the effect of prodigiozan in vivo indicate an increase in their functional activity.
