Fig. 6.

Histograms illustrating hemodynamic responses. A: repeated reflex BP responses were induced by application of bradykinin (BK) on gallbladder every 10 min. The responses were not altered by microinjection of NS into the rvlPAG or cvlPAG. B: inhibition of reflex BP response by bilateral injections of DLH in the ARC nucleus was blocked by bilateral injection of KA in the cvlPAG. C: inhibition of reflex BP response by injections of DLH in the ARC nucleus was not altered by bilateral injection of NS in the rvlPAG or cvlPAG. Numbers below the baseline indicate resting MBP, which were unchanged by the protocols. Δ, Change. *P < 0.05 compared with controls.
