Figure 6.
Adrenal gland and thymus weights from Experiment 2. Data are shown as actual weights (left side of each figure) and relative weights expressed as mg/100 g body weight (right side of each figure). Three weeks after the second cat exposure, the psychosocial stress group demonstrated a smaller thymus (top) and larger adrenal glands (bottom) than the no psychosocial stress group. *p < 0.05; **p < 0.01 versus the no psychosocial stress group. Data are group means ± SEM.
