Figure 5.

Plasma glucocorticoid (GC) level and glucocorticoid receptor (GR) expression in the submandibular glands (SMGs) of control (CN) and heat-exposed (HE) rats. (A) Plasma GC level in the CN and HE groups. Heat exposure significantly increased the plasma GC level in the rats. (B) GR protein expression in the SMGs. Heat exposure did not change GR protein expression level in the SMGs. Left 3 lanes show CN rats, and right 3 lanes show HE rats. *p < 0.05, significant difference between the CN and HE groups. Values are presented as the mean ± SEM (n = 8 in each group).
