On day 28, no rupture-associated mortality was observed in any of the groups; however, the maximal diameter of the suprarenal aorta was significantly increased in the AAA group (1.42 ± 0.09 mm) compared with the sham group (0.58 ± 0.02 mm; p < 0.001; Figure 1a,b), and the diameter became significantly smaller in the AAA + BE group (0.82 ± 0.03 mm) than in the Ang II group (p < 0.001) while the baicalein group had a diameter of 0.59 ± 0.03 mm (p < 0.001), which is smaller than that of the Ang II group. Here, AGT is linked to triple-A syndrome.
