This work was conducted to evaluate the potential antitumor effect of an in vivo plasma treatment on a U87-luc glioma tumor. A pulsed DBD with mu s pulses at moderate power was used for treatment. Electrical analyses and spectroscopic measurements were realized to characterize plasma properties. We showed that the plasma treatment was safe for mice. However, the reiterated long time plasma treatment (20 mm, 3 consecutive days) produces a superficial burn. During plasma treatment, we observed an increase of subcutaneous temperature and a cutaneous skin pH reduction. After 5 d of plasma treatment, we observed a dramatical U87 bioluminescence decrease associated with a reduction of tumor volume in U87 glioma-bearing mice.
