[Comparative evaluation of the action of serum proteins on tissue regeneration].

Processes of skin and long tubular bones' reparative regeneration under the action of serum albumin and alpha-fetoprotein on the body were studied with the use of EPR and histological methods. Relations of spin probe rotatory mobility in cell suspensions and morphological change of examined tissues are shown. It is established that the biological activity of alpha-fetoprotein is more pronounced than that of serum albumin in the effect on the young connective tissue. The stimulating effect of the embryonic protein is demonstrated only in the first week of reparative process while that of serum albumin appeared much more late.
