摘要: 目的 观察Irbesartan对血管损伤后内膜增殖的作用。方法 24只髂总动脉球囊内膜剥脱的Wistar大鼠随机等分为三组,分别于术前上天至术后14天食管内喂饲Irbesartan 30mg/kg,d或蒸馏水。术后14天对损伤血管进行形态学检查。结果 Irbesartan 显著抑制损伤血管壁中细胞计数增加和内膜增厚以及血管平滑肌细胞增殖,并且有量效关系。对新生内膜中细胞密度影响不大。结论 Irbesartan能够抑制大鼠髂总动脉球曩损伤后内膜增殖,Irbesartan 可能是防治血管成形术后再狭窄的有效药物。

Abstract: Aim To study the effect of Irbesartan on neointimal proliferation in vivo after vascular injury.Methods Iliac arteries of Wistar rats were injured with a 2 French balloon catheter.Irbesartan (30mg/kg.d or 10mg/kg.d)or vehicle was given by gavage from 1 day before to 14 days after balloon injury.Morphometrical changes in the injury iliac artery were analyzed.Results Irbesartan significantly inhibited the increase of cell count in injured vessel wall, intimal thickening and vascular smooth muscle cells proliferation in a dosage-dependent relationship.The cellular density of the neointima was not affected by Irbesartan.Conclusion The results indicate that Irbesartan may reduce neointima formation after blloon injury and therefore it may be capable of preventing testenotic lesions after angioplasty in humans.
