Group | Emax | IA | PD2 |
---|---|---|---|
Young controls | 33.70±11.12 | 0.50±0.17 | 6.28±0.66 |
Model group (aging rats) | 25.19±7.81a | 0.39±0.12a | 5.71±0.56a |
Data are expressed as mean ± standard deviation, n=12.
P<0.05 vs. young control. Emax, effect of maximum relaxation; IA, intrinsic activity; PD2, log (50% effective concentration).
