Figure 7. Influence of Ang II in NTS on baroreflex of SHR pretreated with either the vehicle or GF109203.

Figure 7

A and B: Examples of recordings of integrated SNA (μV), HR (bpm) and PP (mm Hg) for (A) vehicle- or (B) GF109203-treated SHR. Baroreceptors were stimulated by pressor ramps (~2–5 sec) before and after bilateral microinjections of Ang II (10 μM; 50–60nl/side). C and D: Grouped values for the cardiac baroreflex gain (C) and sympathetic baroreflex gain (D) following Ang II injection in the NTS of the SHR pre-treated with either the vehicle (black bars) or GF109203 (white bars) presented as percentage of control baroreflex gain (i.e. the gain measured prior to any of the injections). *P<0.05 vs. control baroreflex gain; #P<0.05 and ##P<0.01 vs. Vehicle. bpm = beats/min
