[2] Filatov is also credited for restoring Vasily Zaytsev's sight when he suffered an injury to his eyes from a mortar attack during Battle of Stalingrad.

He asked for an Orthodox funeral conducted by a bishop, and he wanted to be buried, with the tomb stone proclaiming "I look for the resurrection of the dead."

[6] As it seemed to Filatov in the time of engaging in that practice, the method also cured a number of diseases not connected to corneal opacity.

He suggested that a piece of tissue placed in unfavorable conditions (cold and darkness) which still do not kill it, changes its metabolism for producing some yet unknown compounds, that serve saving it alive as long as possible.

[7] Then he applied the same method to treating skin diseases, and (by 1933) he formulated main postulates of his doctrine of biogenic stimulators and tissue therapy.

These extracts are used subcutaneously as pharmaceutical and veterinary remedies in post-Soviet countries[9] against inflammation, degeneration, atrophy, and other slow pathological processes.
