[The morphofunctional characteristics of the macrophages during reparative myogenesis under the action of immunomodulators].

The electron transmission microscopy was used for studying the ultrastructure of macrophages involved in the reparative regeneration of skeletal muscles of Wistar rats after a mechanical injury. Two morphofunctional types were established with special reference to ultrastructural features of the macrophages and morphometrical characteristics of organelles of these cells. The first type includes macrophages with a strong lysosomal apparatus and great amount of phagosomes containing a muscular dendritis.

[Cell-differon organization of the tissues and the problem of wound healing].

Problems on correlation of processes of normal histogenesis and those of physiological and reparative regeneration are discussed. A special attention is paid to the cellular-differon organization of tissue and its significance for understanding cellular mechanisms and ultrastructural bases in tissue regeneration after lesions and use of biostimulators of various origin. Certain peculiarities have been revealed in changes of intra- and interdifferon interrelations of cells in various tissues at regenerative histogenesis.
