Serum corticosterone concentration in control (C), restrained (R) and hindlimb unloaded (HU) mice.

<p>Trunk blood was collected immediately after the sacrifice. Corticosterone concentration was measured using an ELISA kit with a detection threshold of 16.9/ml. Each experimental group was compared to the others. <i>n</i> = 4, 6 and 4 mice for C, R and HU groups, respectively. No significant difference was found using an ANOVA and Tukey <i>post-hoc</i> test.
