A: Relaxation to acetylcholine in vessels of young and aged AL fed and aged CR F344 rats. Administration of PEG-SOD (200 U/mL; Panel B) improves endothelial function in vessels of aged AL rats and abolished the differences between the groups. Data are mean ± S. E. M. (n=5–7). *P<0. 05 vs aged AL. C: Superoxide production in aortic segments of young and aged AL fed and aged CR fed F344 rats, as measured by the lucigenin chemiluminescence (CL) method. *P<0. 05 vs. young AL, #P<0. 05 vs. aged AL. D: Superoxide production in aortic segments of young and aged AL fed and aged CR fed F344 rats, as measured by the DHE fluorescence method. *P<0. 05 vs. young AL, #P<0. 05 vs. aged AL.
