Laminal distribution of apoptotic cells
| Group | I–II | III–IV | V–VI |
|---|---|---|---|
| Saline bolus | 0.5 ± 0.3 | 0.2 ± 0.2 | 0.3 ± 0.3 |
| 10 μg MS bolus | 8.7 ± 0.6* | 0.3 ± 0.1 | 1.1 ± 0.31-160 |
| 20 μg MS bolus | 10.7 ± 1.31-165 | 0.5 ± 0.1 | 1.6 ± 0.41-160 |
| Saline infusion | 0.4 ± 0.2 | 0.2 ± 0.2 | 0.2 ± 0.4 |
| 10 nmol·μl−1·hr−1 MS | 8.1 ± 1.5* | 0.4 ± 0.3 | 0.6 ± 0.3 |
| 20 nmol·μl−1·hr−1 MS | 11.9 ± 0.71-165 | 0.6 ± 0.1 | 0.9 ± 0.41-160 |
The data represent the mean ± SE number of apoptotic cells in a given group averaged from five or six sections per rat.
*
p < 0.01;
F1-160: p < 0.05, compared with the saline group,
F1-165: p < 0.01 compared with both saline and 10 μg or 10 nmol·μl−1·hr−1 morphine (MS) groups.
