Effects of sub-acute co-exposure to WIFI (2.45 GHz) and Pistacia lentiscus oil treatment on wound healing by primary intention in male rabbits

Background: The bioeffects of WIFI on cutaneous wound healing remains unexplored. In addition, several medicinal plant products including lentisk oil have been shown to interfere with wound healing process. Since the use of this oil is increasing, the co-exposure (WIFI-Lentisk oil) assessment is of paramount importance. Objectives: We aimed in the present study to investigate the effects of WIFI exposure as well as the application of Pistacia lentiscus oil on sutured wounds (SW). Methods: New Zealand male rabbits (n = 24) were used and randomly divided into four groups of six animals each: a control group (SW) and three experimental groups (i) a first group exposed to WIFI (2.45 GHz, 6 h/day) during 16 days (SWW); (ii) a second group exposed to WIFI (2.45 GHz, 6 h/day) during 16 days and treated with lentisk oil (SWWL) and (iii) a third group not exposed to WIFI but treated with lentisk oil (SWL). The wound healing was evaluated by monitoring clinical parameters (temperature, food intake, relative weight variation, and macroscopic aspect) and histology. Results: The mean food intake was higher in the SWWL group compared to the three other groups (p < 0.001) and higher in the SWL group compared to the SW group (p = 0.014). The exposition to WIFI (SWW group) or lentisk oil application (SWL group) can promote the collagen deposition and ameliorate the general aspect of wounds. By contrast, the co-exposure to WIFI and lentisk oil (SWWL) results in antagonist effects and extends the inflammatory phase of wound healing. Conclusions: Wounds treated topically with Pistacia lentiscus oil should not be exposed to WIFI.

Automated summary

The effects of WIFI exposure and the application of Pistacia lentiscus oil on wound healing were investigated in this study. It was found that WIFI exposure or lentisk oil application can promote collagen deposition and improve the overall condition of wounds. However, co-exposure to WIFI and lentisk oil extended the inflammatory phase of wound healing.
