Figure 4: GTs alleviated the initial oxidative stress in the endothelium after ligation.(a) LCA and RCA from mice receiving Con (DMSO) or GT (300 mg/kg/day; s.c.) treatment were excised 3 days after ligation before any structural change occurred. Arterial tissue sections were processed for DHE staining. An arrow indicates a DHE+ (red)/CD31+ (green) EC. Yellow dashed lines delineate the internal elastic lamellae. Bar: 25 μm. (b) The percentages of DHE+ ECs are means ± SEM from 8 serial sections from each artery ( for each group). Statistical significance was calculated using two-way ANOVA and post hoc Tukey’s tests, .
