Table 1. Pain threshold: stimulation intensity of the escape reaction in the von Frey method (mean ± SD).

Evaluation time	Pain threshold (g)
Normal state	23.0 ± 4.1
3 hours	16.6 ± 4.5 *
1 day	12.8 ± 3.3 *
2 days	14.6 ± 2.2 *
3 days	15.5 ± 3.0 *
4 days	17.1 ± 2.9 *
5 days	19.5 ± 3.0
6 days	18.5 ± 2.2
7 days	21.5 ± 2.1

Evaluation time is the time elapsed after ischemia-reperfusion.
