J Periodontal Res: :龈沟局部应用甘草次酸对脂多糖诱导的实验性牙周炎附着丧失的抑制作用

2018-07-26 MedSci MedSci原创

结合上皮的附着丧失和牙槽骨破坏是牙周炎的征兆,主要由牙菌斑引起的炎症反应导致。 Glycyrrhetinic acid(GA)是甘草的一种成分,已被证明具有重要的抗炎活性;然而,之前没有关于其抑制牙周病的能力的报道。因此,本研究中使用实验性牙周炎模型评估GA是否对附着丧失和牙槽骨吸收有预防作用。

结合上皮的附着丧失和牙槽骨破坏是牙周炎的征兆,主要由牙菌斑引起的炎症反应导致。 Glycyrrhetinic acid(GA)是甘草的一种成分,已被证明具有重要的抗炎活性;然而,之前没有关于其抑制牙周病的能力的报道。因此,本研究中使用实验性牙周炎模型评估GA是否对附着丧失和牙槽骨吸收有预防作用。

用大肠杆菌脂多糖(LPS)腹腔内免疫大鼠。 LPS组(n = 5)接受3次50μg/μL LPS局部应用,然后将一次载体(丙二醇:乙醇:磷酸盐缓冲盐水[PBS] = 8:1:1)施用到龈沟中。该方案每天重复两次,持续10天。低(n = 5)和高(n = 5)组分别局部施用LPS和0.03%或0.3%GA。对照组接受PBS和载体的局部应用。第10天处死大鼠。通过组织学研究附着丧失,牙槽骨水平和炎性细胞浸润。免疫组织学评估免疫复合物的形成和LPS的浸润。

结果:与对照组相比,LPS组的附着丧失,免疫复合物的形成和炎性细胞的浸润增加,并且与LPS组相比,在低和高组中完全抑制。与对照组和GA治疗组相比,LPS组显示出更多的牙槽骨吸收。此外,在LPS组中检测到LPS的侵袭,而对照组中没有,并且在GA处理组中比在LPS组中更弱。

在本研究发现GA抑制大鼠实验性牙周炎模型中的牙周破坏。

J Periodontal Res: :牙周膜细胞在牙龈卟啉单胞菌脂多糖刺激下内毒素耐受性的变化

内毒素耐受性即低浓度的脂质多糖(LPS)对抗内毒素后的低反应性状态。本实验旨在研究牙龈卟啉单胞菌预处理是否导致内毒素耐受诱导和人牙周膜细胞(hPDLCs)中Toll样受体(TLR)-2和-4诱导反应的改变。

脂多糖(LPS)是引起深龋和牙髓炎时革兰阴性菌外膜的主要组成部分。当细菌侵入牙本质小管和牙本质持续受到损伤时,预先存在的成牙本质细胞会形成修复性牙本质。然而,LPS与修复性牙本质的关系还未可知。这篇研究的目的是为了评估LPS刺激是否会诱导人牙髓细胞(hDPCs)的硬组织形成。
