From: Nicorandil attenuates carotid intimal hyperplasia after balloon catheter injury in diabetic rats
Inflammatory cell infiltration in injured carotid arteries. a IHC staining of CD 68 in DM-sham group, DM-injury group, DM-injury + nicorandil group, and DM-injury + nicorandil + 5HD group. b Quantitative analysis of CD 68-posotive cells per 104 μm2. Nicorandil decreased CD 68-positive macrophages in balloon injured arteries. This decrease was reversed by 5-HD. Bars represent mean ± SE. **p < 0.01
