Ontogenic changes in fetal cortisol and catecholamines during chronic hypoxia and normoxia
| Normoxia | Hypoxia | |||
|---|---|---|---|---|
| Baseline | Day 13 | Baseline | Day 13 | |
| Cortisol (ng ml−1) | 11.9 ± 1.4 | 24.1 ± 1.8* | 13.8 ± 1.8 | 32.2 ± 5.2* |
| Noradrenaline (ng ml−1) | 1.1 ± 0.3 | 0.8 ± 0.1 | 0.7 ± 0.1 | 0.6 ± 0.1 |
| Adrenaline (ng ml−1) | 0.09 ± 0.02 | 0.07 ± 0.02 | 0.06 ± 0.01 | 0.07 ± 0.01 |
Values represent the mean ± SEM of plasma concentrations of fetal cortisol, noradrenaline and adrenaline at baseline (122 ± 1 days GA) and 2 days after the end of chronic hypoxia/normoxia (day 13, 136 ± 1 days GA). Significant differences (P < 0.05): *significant effect of gestational age (RM two‐way ANOVA with post hoc Tukey's test).
