Background: Healing ability of nonhealing chronic ulcers can be assessed by estimating hydroxyproline, total protein and enzymatic antioxidants such as glutathione peroxidase (GPx), glutathione S-transferase (GST) in the granulation tissue.
Materials And Method: A total of 34 patients were analysed from two groups: Limited access dressing (LAD) group (n = 17) and conventional dressing group (n = 17).
Results: Patients treated with LAD that exerts combination of intermittent negative pressure and moist wound-healing had shown a significant increase in the hydroxyproline (P = 0.026), total protein (P = 0.004), GPx level (P = 0.030) and GST level (P = 0.045).
Conclusion: Patients treated with LAD indicated significantly better anabolic effect on wound-healing compared to that of patients treated with conventional dressing.
