Figure 1 ESR spectra of mouse skin treated with DHA. (a) ESR spectrum of mouse skin treated in vivo with DHA, 48 h after application, five scans averaged: (b) ESR spectrum of untreated mouse skin, five scans averaged; (c) ESR spectrum of mouse skin treated ex vivo with DHA in phosphate buffer, after 8 h at 37°C; (d) ESR spectrum of mouse skin treated ex vivo with phosphate buffer alone, after 8 h at 37°C. ESR parameters: scan range 100 Gauss; scan time 2 min; modulation amplitude 2.0 Gauss; time constant 0.25 s; microwave power 20 mW; one scan except as noted.
