Fig. 1 — HO^• generation from H₂O₂ by ultrasound irradiation. (A) and (B) ESR spin trapping measurement of HO^• generated from H₂O₂ by 10 W (A) and 20 W (B) ultrasound with CYPMPO as the spin trap. The asterisk (*) indicates the signal intensity used for the analysis of HO^• generation. (C) Signal intensities of the ESR spectrum of CYPMPO-OH by 10 and 20 W ultrasound. Results are expressed as the mean ± SD. Within experimental solutions, means sharing the same upper-case letter are not significantly different (p>0.05). Between experimental solutions at the same irradiation time, means sharing the same lower-case letter are not significantly different (p>0.05). (D) Influence of DMSO on ESR spectra of HO^• generated from H₂O₂ by 20 W ultrasound with CYPMPO as the spin trap.
