Floating discharge plasma for healing of tendon injury

In this paper the effect of irradiation of cold plasma on the skin for healing of injured tissue, which is located inside a body (such as tendon), is evaluated. Cold plasma was applied to the rabbits skin after suturing and continued for $21$ days. After $21$ days the tendon tissue was considered histological. The results show that cold plasma treatment led to reduction of the inflammatory cells and acceleration of the recovery phase by increase neovascularization and collagen production. At the non-touching cold plasma production of ultraviolet, neutral radicals, and electric fields led to some effect on cells. To find the effect of electric fields, ultra violet, and reactive oxygen species, the indirect plasma treatment compared to direct treatment. To produce indirect plasma, a grounded mesh was put as a second electrode. The results of this study confirm that the cold plasma treatment of skin has positive effect on healing of tissue inside a body. The electric fields has no effect on the healing process. Results of this study show that reactive oxygen species is the parameters that causes healing.
