摘要
目的 :观察氨基胍 (AG)对牙周炎的作用。方法 :采用丝线结扎法建立大鼠牙周炎模型 ;利用分光光度仪测定大鼠牙龈组织中亚硝酸盐 (NO- 2 )含量 ,以间接确定一氧化氮 (NO)含量 ;应用Tiger细胞图象仪分析牙周附着丧失 ;采用组织切片法观察牙周组织的病理学改变。结果 :AG能明显降低大鼠牙周炎牙龈NO含量 ,抑制牙周组织附着丧失和减轻炎症程度。结论 :AG通过选择性抑制诱导型一氧化氮合酶 (iNOS) ,降低牙周组织NO含量 ,达到减轻牙周组织炎症程度的作用 。
AIM: To study the inhibitory effect of aminoguanidine(AG) on periodontitis. METHODS: Experimental periodontitis was produced in rats by a ligature of braided silk, the NO concentration was assayed by spectrophototometry, the attachment loss of periodontium was measured by using technology for image and graphics engineering research and the histopathologic changes of periodontium were also examined under a light microscope. RESULTS: The NO concentration significantly decreased after AG treatment for 4 weeks, and the inflammation and the damages of periodontium was also reduced significantly. CONCLUSION: The inhibition of iNOS by AG may be a potential therapeutic strategy for the treatment of periodontitis.
