TITLE:

Thermographic and histopathological study of the effects of plasma jet therapy on the tissue
repair process in rats.

SUMMARY:

Biomodulatory therapies have been used to improve the healing pattern and assist in the tissue
repair process. Plasma jet is an electrotherapeutic resource that is currently being highly 

recommended for dermatological use and aesthetic purposes in order to treat wrinkles and
expression lines, stretch marks and acne scarring. Additionally, studies have proven its
bactericidal action, a fact that can expand its use for other therapeutic purposes. Objective: To
evaluate the effects of plasma jet in the repair of standardized surgical wounds in the skin of
rats through infrared thermographic imaging and histopathological analysis.
Methodology: A total of 20 animals were used, divided into two groups, the control group (GC)
and the group treated with the plasma jet (GJP). A standardized cutaneous surgical wound was
performed on the animals' back and thermographic recording was carried out at different times.
The control group did not undergo any type of therapy, whereas in the PJG, plasma jet therapy
was performed (conduction mode, direct current, intensity of 5/8 and time of 90 seconds),
immediately after surgery, and on the two days following. Half of the animals in each group
were sacrificed on the 5th day after the surgical procedure, and the remainder on the 10th day.
A tissue sample was removed from each animal for processing and histological analysis.
Statistical analysis was performed. Result: It was found that the highest Delta T occurred in the
group treated with plasma jet, especially on the 5th day (p>0.05). Conclusion: The present study
found that infrared thermography proved to be an efficient resource for capturing temperature
variations in the skin of rats during skin repair. The analysis of the thermograms showed that
the application of the plasma jet in the surgical wounds generated a significant thermal variation
in relation to the specimens of the control group, especially on the 5th day of the healing period.
