Western blotting of GPR30, PKA, and GABAA α4, β1, and δ subunits in periaqueductal gray neurons of different groups (n = 6/each group). β-actin was used as a loading control. The expressions of GPR30 and PKA in Group G1 and Group S + I were significantly higher than in other groups (a-f). Further, Group S + I showed higher intensity of the GPR30 and PKA than Group G1. *P < 0.05, **P < 0.01 compared with Group C; #P < 0.05 compared with Group G1; &P < 0.05, &&P < 0.01 compared with Group S + I
