Figure 1

The first derivative EPR spectrum of paramagnetic centers: the high-spin Fe³⁺ in methemoglobin (line I), high-spin Fe³⁺ in transferrin (line II), and Cu²⁺ in ceruloplasmin and free radicals (line III), in the blood for skin burned wounds treated with new generation biodegradable dressings containing poly(lactide-co-glycolide), at (a) 1 day, (b) 10 days, and (c) 21 days of therapy.
