The effects of AII and BSO on neointimal regression in cuff-injured arteries.

(A) Representative light micrographs of femoral artery cross sections. 4 weeks after cuff injury, arteries were stained with hematoxylin and eosin: control artery without cuff (Cuff(−)), cuff injured control artery (Control), treated with BSO (BSO), AII (AII), and AII and BSO (AII+BSO). Scale bars indicate 50 µm. Graphs show ratio of intimal area to medial area (I/M ratio) (B) and ratio of wall (media) to lumen (C) of cuff injured artery. Bar graphs represent mean ± SD (*p<0.05 vs AII+BSO, n = 7 of each).
