N-acetyl cysteine promotes angiogenesis and clearance of free oxygen radicals, thus improving wound healing in an alloxan-induced diabetic mouse model of incisional wound

Abstract

A mouse model of incisional wound treated with NAC resulted in lower levels of tissue oxidative stress, higher levels of tissue glutathione, and downregulation of iNOS expression coupled with upregulation of VEGF expression, producing an overall favourable clinical outcome of higher WBS and a shorter wound-healing period both in diabetic and nondiabetic mice. Both antioxidant and anti-inflammatory properties of NAC may be involved in this improved healing process for incisional wounds.
