Research Abstract

A new synthetic nonadecapeptide corresponding to Glu22-Leu40 of staphylokinase
molecule bound to plasminogen (Plg) and enhanced the activation of Plg by Plg activator (PA). When new synthetic peptide and bFGF were administrated in mouse skin wound healing model, acceleration of skin healing was observed than in mice with vehicle administration. Thus, new synthetic peptide enhanced Plg
activation and induced effective tissue repair.
