Table I.
Changes in the mean number of pyramidal neurons of the hippocampal CA1 region of gerbils in the ischemia and IPC + ischemia groups.
| Time post-I-R (days) | Ischemia-operated group

IPC + ischemia-operated group

|---|---|---|---|---|
| NeuN+ | F-J B+ | NeuN+ | F-J B+ | |
| Sham (no I-R) | 346±13.54 | 0 | 352±16.28 | 0 |
| 1 | 352±11.12 | 0 | 349±18.36 | 0 |
| 2 | 349±12.98 | 4±4.36a | 355±17.34 | 0 |
| 5 | 41±8.35a,b | 134±17.69a,b | 324±15.85a,b | 24±5.54a,b |
Numbers of NeuN+ and F-J B+ cells were counted in a 200×200 µm square of the stratum pyramidale of the CA1 region following I-R (n=7 per group;
a
P<0.05, compared with the sham group;
b
P<0.05, compared with the 2 days). I-R, ischemia-reperfusion; IPC, ischemic preconditioning.
