TABLE 2.
Effect of CVS on unstressed plasma hormone levels (novel environment challenge)
| Plasma ACTH (pg/ml) |
Plasma corticosterone (ng/ml) |
|
|---|---|---|
| 16 h Control (n = 6) | 55 ± 12 | 28 ± 10 |
| 16 h CVS (n = 6) | 52 ± 5 | 109 ± 31a |
| 7 d CVS (n = 6) | 39 ± 5 | 17 ± 7 |
Plasma hormone levels in the unstressed control or CVS treated rats not exposed to the novel environment were measured at 16 h or 7 d after cessation of CVS. Values represent the mean ± SEM of each group.
a
Significant difference from 16 h control group (P < 0.05).
