Changes in the mean average number of pyramidal neurons of the ischemic hippocampal CA1 region in the adult and young gerbils
| Time after I-R | NeuN-immunoreactive neurons | F-J B-positive cells | ||
|---|---|---|---|---|
| Adult | Young | Adult | Young | |
| Sham | 90 ± 4.32 | 85 ± 3.65 | 0 | 0 |
| 4 days | 9 ± 1.71* | 86 ± 2.01+ | 50 ± 3.79* | 0 |
| 7 days | 10 ± 3.65* | 40 ± 1.76*#+ | 54 ± 1.24* | 16 ± 1.11*#+ |
| 15 days | 13 ± 1.56* | 42 ± 3.42*+ | 57 ± 3.41* | 21 ± 3.03*+ |
The mean number of NeuN-immunoreactive neurons and F-J B-positive cells was counted in a 250 X 250 μm square of the stratum pyramidale of the CA1 region after ischemia-reperfusion (I-R) (n=7 per group;
*
P<0.05, significantly different from the corresponding sham-group;
#
P<0.05, significantly different from the respective pre-time point group;
+
P<0.05, significantly different from the corresponding adult-group)
