Cold plasma on full-thickness cutaneous wound accelerates healing through promoting inflammation, re-epithelialization and wound contraction
Available online 28 January 2014
We investigated cold plasma effects on acute wounds of mice. The mice were classified into experimental and control groups. In the former, wounds were treated using cold plasma once daily for 1 min, and then covered with hydrocolloid dressing; wounds in the control were left to heal under hydrocolloid dressing. Daily evaluation was conducted for 15 days. General and specific staining was applied to evaluate re-epithelialization, neutrophil, macrophage, myofibroblast and transforming growth factor beta. It was found that cold plasma accelerated wound healing by 1 day. Plasma may promote the late phase of inflammation, accelerate re-epithelialization and increase wound contraction. More detail:
