Topical and Systemic Effects of N-acetyl Cysteine on Wound Healing in a Diabetic Rat Model

0

Main idea: The results of this study show that both topical and systemic administration of NAC improved wound healing in a diabetic rat model. This effect of NAC may be related to its antioxidant properties since a reduction in oxidative stress parameters in both tissue and serum were shown in the present study.

Abstract

Objective: This study evaluates the effects of topical and systemic N-acetyl cysteine (NAC) treatment on wound healing in a diabetic rat model.

Results: On day 14, the wounded area in groups of patients with ulcers was found to be smaller than in the control group. Histopathologically, epithelialization and fibrosis scores were significantly lower, whereas the inflammation score was higher in the control group than in the other groups. Tissue oxidative stress parameters (malondialdehyde, fluorescent oxidation products, total oxidative stress) were higher in the control group than in the other groups. In patients which received systemic NAC, the oxidative stress parameters in serum samples were lower than those of the control group and group 2. Serum sulphydryl levels were the lowest in group 1.
