a Effect of CAP on cellular activity of human dermis (Ø 15 mm, 1 mm thickness) placed on chicken meat. Distance between plasma and tissue was increased by adding layers of skin surrounding the dermal samples. Plasma was applied for the indicated times. Cellular activity was measured with MTT in 3 punch biopsies (Ø 4 mm) and is expressed as relative to the untreated controls (in %). Mean values and standard deviation are shown (n= 4–7 in duplicate). b Effect of repeated CAP treatment on cellular activity of human dermis measured with MTT. Plasma was applied on consecutive days for the indicated times in the x-axis. Dermal samples were incubated in FBM at 37°C, 5% CO2. Mean values and standard deviation are shown (n= 3–5 in triplicate). * Significant difference, p<0.05 (WMP)
