Comparison between the ¹²⁵ I-TNC-Ab uptake ratios in rats with and without postconditioning. ¹²⁵I-TNC-Ab uptake ratio was calculated by dividing the ¹²⁵I-TNC-Ab count density in the area at risk by that of non-ischemic area. ¹²⁵I-TNC-Ab uptake ratio in rats without postconditioning at 1 day after reperfusion was 3.73 ± 0.71 and increased at 3 days (4.65 ± 0.87), followed by a significant reduction at 7 days after reperfusion (2.91 ± 0.55, P < 0.005 vs 3 days) and a further reduction at 14 days (2.01 ± 0.17, P < 0.005 vs 1 and 3 days). Postconditioning attenuated the ¹²⁵I-TNC-Ab uptake ratio throughout the reperfusion time from 1 to 14 days; 2.59 ± 0.59 at 1 day, P < 0.05: 3.10 ± 0.42 at 3 days, P < 0.005: 1.93 ± 0.37 at 7 days, P < 0.05, 1.40 ± 0.07 at 14 days, P < 0.001.
