*, P<0.05 when comparing untreated chronic hypoxia vs. normoxia;

#, P<0.05 when comparing the various treatments vs. untreated chronic hypoxia;

$, P<0.05 when comparing the two treatments between them. All post-tests performed with the Bonferroni method.

Data are mean±SEM.

ANOVA P<0.0001 for all measurements.
