[The reaction of regenerating connective tissue to acetylcholine in the dynamics of the denervation-reinnervation process].

The granulation tissue of wounds on upper surface of feet on the 7th day under repeated acetylcholine (Ach) application (0.02 g/1) was studied. In the control group, Ach-induced intensification of inflammatory process and bad condition of regenerating tissue of skin. This pathological reaction increased (fastly appeared ulceration) at once after crushing of right sciatic nerve in the denervated wound. It was less pathological in the contralateral (innervated) wounds. The effect of ACh was positive on later term of neurodystrophic process in the denervated wound and in the contralateral one. Cholinoceptive of granulation tissue of bilateral wound became normal after reinnervation.
