Effect of Tongxinluo (TXL) on neointimal hyperplasia in rat carotid arteries at day 14 after injury. (a) Photomicrographs showing the effect of TXL on neointima formation in rat carotid arteries 14 days after balloon injury (Magnification × 200). Hematoxylin-eosin (HE) staining of cross section of the specimens treated without (control) or with low-dose Tongxinluo (TXL-L) or high-dose Tongxinluo (TXL-H). (b) The intimal to medial area ratio of the arteries were determined 14 days after injury. Data are expressed as mean ± SEM (n = 5). * P < 0.05 vs. control group; # P < 0.05 vs. sham group
