[A new peptide activator of reparative tissue regeneration].

Synthetic analog of leucine enkephalin--hexapeptide dalargin was shown to stimulate healing of skin wounds in rats, dogs and mini-pigs at local and parenteral administration in doses of 0.1-100 micrograms/kg. Acceleration of proliferation with an increase of fibroblast mitoses, earlier and active growth of vascular elements, rapid maturation of granulation tissue and accelerated epithelialization were observed.
