Abstract

Cigarette smoking is one of the main predisposing factors for atherosclerosis, which can lead to vascular inflammation. Emerging research has demonstrated that the rate of restenosis is increased following angioplasty in smokers. Sophocarpine, one of the Sophora alkaloids, can play the antiinflammatory role in cells. This study aimed to assess whether sophocarpine can alleviate the restenosis induced by cigarette smoke in rats post-angioplasty. Fifteen male Sprague-Dawley rats were randomized into three groups (control group, smoking group, smoking and injected with sophocarpine group). An established balloon-induced carotid artery injury was performed to all the groups. For the balloon-injured carotid arteries, Verhoeff-Van Gieson stain was used to detect the area of neointima and media. Then the ratio of neointima to media (I/M ratio) was calculated. For the contralateral carotid arteries, the level of MAP kinase kinase 3 (MKK3), MAP kinase kinase 6 (MKK6), Phospho-MKK3/6, p38, Phospho-p38, interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) were measured. The I/M ratio of smoking group is larger than that of control group. However, sophocarpine could dramatically reduce the I/M ratio compared to smoking group. Cigaret...Continue Reading
