Age- and Gender-Related Differences in Renal Vascular Responses to Angiotensin II in Rats: The Role of the Mas Receptor

Figure 6

The effect of the vehicle or A779 infusion on the percentage (%) changes of renal blood flow (RBF) and renal vascular resistance (RVR) in response to the infusion of angiotensin II (Ang II) graded doses in 8–12-week (a, b) and 24–28-week (c, d) animals in both genders. Data were expressed as the mean ± standard error of the mean. The symbols ^∗∗ indicate a significant difference in comparison to the 8–12-week male group receiving vehicle (P group ≤ 0.01); the symbols ^## indicate a significant difference in comparison to the 8–12-week male group receiving A779 (P group ≤ 0.01).
