J Periodontal Res:瑞舒伐他汀对高血压大鼠实验性牙周炎的保护作用

2017-07-29 MedSci MedSci原创

他汀类药物调节牙周病的潜在益处在体外和临床研究中得到支持,提出他汀类可以诱导促炎细胞因子和基质金属蛋白酶的低表达。本研究的目的是评估瑞舒伐他汀(ST)对自发性高血压大鼠(SHR)结扎诱导的牙周炎的影响。

他汀类药物调节牙周病的潜在益处在体外和临床研究中得到支持,提出他汀类可以诱导促炎细胞因子和基质金属蛋白酶的低表达。本研究的目的是评估瑞舒伐他汀(ST)对自发性高血压大鼠(SHR)结扎诱导的牙周炎的影响。材料与方法:将54只成年雄性大鼠分为SHR-C,SHR-L和SHR-L-ST(C,对照组; L,结扎组)三组。在SHR-L-ST组中,每日给2mg / kg ST。在L组中,在下颌第一磨牙周围保留结扎10天。每组在术后10或21 d处死。进行微观和组织学分析。,通过酒石酸耐性酸性磷酸酶评估破骨细胞的产生和通过聚合酶链反应评估84个促炎介质的基因表达。结果:术后10天和21天,SHR-L-ST组的骨吸收和附着丧失均少于SHR-L组(p <0.05)。术后 10天和21天,STR均使得酒石酸耐药性酸性磷酸酶阳性细胞数量减少(p <0.05)。 SHR-L-ST组与SHR-L组相比,有14个基因表达差异,第10 d后基因表达下调。结论:他汀类药物治疗可以通过炎症基因谱调控,促进对高血压大鼠实验性牙周炎的牙槽骨吸收和结缔组织附着丧失的保护作用。原始出处:M.
