Effects of bradykinin on the survival of multiterritory perforator flaps in rats

a Photographs of the postoperative flaps from the bradykinin and control groups on day 7. b The flap survival rate (%) in the bradykinin group (85.83？±？0.98%) and control group (71.83？±？2.52%). c The perfusion images of a flap on POD 7. Red denotes high perfusion, and blue denotes low perfusion with the scale bar. d The perfusion value on POD 7 (control group, 428.38？±？23.39; bradykinin group, 505.85？±？25.52). n？=？5 per group. *P？<？0.05, **P？<？0.0
