From: Estimation of restraint stress in rats using salivary amylase activity
Fractions of weights of the adrenal glands (a) and thymus (b) relative to body weight of control and stress rats (14 weeks of age). Data show percent values. The fraction of the weight of the adrenal glands of the stress rats was greater than that of the control rats († P < 0.01). There was no significant difference in the fraction of the weight of the thymus between the stress and control rats. White and black columns indicate the percent values of the control and stress rats, respectively. Error bars SD (n = 12)
