Fig. 4From: Safety and bactericidal efficacy of cold atmospheric plasma generated by a flexible surface Dielectric Barrier Discharge device against Pseudomonas aeruginosa in vitro and in vivoSusceptibility of V79 fibroblasts to H2O2. V79 fibroblasts in Matriderm® were exposed to varying concentrations of H2O2 (0–0.15%; v/v) for 4 min. Subsequently, the metabolic activity per V79 fibroblast was determined. Results are expressed relative to the unexposed control. Data represent the means of five independent experiments performed in duplicate. Statistical differences compared to control samples are indicated: *p < 0.05; **p < 0.01; ***p < 0.001 (MWU)Back to article page
