Periodontitis and rheumatoid arthritis (RA) are inflammatory diseases characterized by chronic inflammation and bone erosion. Electroacupuncture (EA) shows anti-inflammatory and anti-resorptive effects in experimental periodontitis (EP) and in RA. It is important to investigate whether EA shows these effects in periodontal tissues in the presence of these two inflammatory diseases or not. For this, Wistar rats were divided into six groups: control (C); experimental rheumatoid arthritis (RA; bovine type II collagen-induced (CII)); experimental periodontitis (EP); RA/EP (RA + EP); EP/EA (EP treated with EA); RA/EP/EA (RA + EP treated with EA). EP was induced 21 days after RA induction and EA was performed previously and during the EP induction period, every 3 days until the 36th experimental day. The rats were euthanized on day 39. RA was evaluated by edema and the withdrawal threshold of hind paws. The maxillae were removed, and alveolar bone loss (ABL) and bone radiographic density (BRD) were evaluated. Immunohistochemical analyses for interleukins (IL)-6 and -17 and nuclear factor (NF)-κB were performed. Our results showed that EA reduced only the pain intensity in arthritic rats. Histomorphometric, macroscopic, and radiographic analyses did not show differences between the control and EP/EA groups. EA caused a reduction in ABL and BRD only in the presence of EP. EA caused a reduction in IL-6 and -17 in all groups, but NF-κB was only reduced in the arthritic rats with EP. In conclusion, EA reduced the inflammation related to periodontitis in arthritic rats but did not prevent ABL.

电针可减少关节炎大鼠牙周炎的炎症,但不会减少骨质流失。

牙周炎和类风湿性关节炎 (RA) 是以慢性炎症和骨侵蚀为特征的炎症性疾病。电针 (EA) 在实验性牙周炎 (EP) 和 RA 中显示出抗炎和抗吸收作用。在存在这两种炎症性疾病的情况下,研究 EA 是否在牙周组织中显示出这些影响是很重要的。为此,Wistar 大鼠分为六组:对照组(C);实验性类风湿性关节炎(RA;牛II型胶原诱导(CII));实验性牙周炎 (EP); RA/EP (RA + EP);EP/EA(用EA处理的EP);RA/EP/EA(用 EA 处理的 RA + EP)。EP 在 RA 诱导后 21 天进行诱导,EA 在之前和 EP 诱导期间进行,每 3 天一次,直到第 36 个实验日。在第 39 天对大鼠实施安乐死。通过水肿和后爪的缩回阈值评估RA。去除上颌骨,评估牙槽骨丢失(ABL)和骨放射密度(BRD)。对白细胞介素 (IL)-6 和 -17 以及核因子 (NF)-κB 进行免疫组织化学分析。我们的结果表明,EA 仅降低了关节炎大鼠的疼痛强度。组织形态学、宏观和放射学分析未显示对照组和 EP/EA 组之间存在差异。仅在 EP 存在的情况下,EA 才导致 ABL 和 BRD 降低。EA 导致所有组中 IL-6 和 -17 的减少,但 NF-κB 仅在 EP 的关节炎大鼠中减少。总之,EA 减少了关节炎大鼠与牙周炎相关的炎症,但不能预防 ABL。评估牙槽骨丢失(ABL)和骨放射密度(BRD)。对白细胞介素 (IL)-6 和 -17 以及核因子 (NF)-κB 进行免疫组织化学分析。我们的结果表明,EA 仅降低了关节炎大鼠的疼痛强度。组织形态学、宏观和放射学分析未显示对照组和 EP/EA 组之间的差异。仅在 EP 存在的情况下,EA 才导致 ABL 和 BRD 降低。EA 导致所有组中 IL-6 和 -17 的减少,但 NF-κB 仅在 EP 的关节炎大鼠中减少。总之,EA 减少了关节炎大鼠与牙周炎相关的炎症,但不能预防 ABL。评估牙槽骨丢失(ABL)和骨放射密度(BRD)。对白细胞介素 (IL)-6 和 -17 以及核因子 (NF)-κB 进行免疫组织化学分析。我们的结果表明,EA 仅降低了关节炎大鼠的疼痛强度。组织形态学、宏观和放射学分析未显示对照组和 EP/EA 组之间的差异。仅在 EP 存在的情况下,EA 才导致 ABL 和 BRD 降低。EA 导致所有组中 IL-6 和 -17 的减少,但 NF-κB 仅在 EP 的关节炎大鼠中减少。总之,EA 减少了关节炎大鼠与牙周炎相关的炎症,但不能预防 ABL。我们的结果表明,EA 仅降低了关节炎大鼠的疼痛强度。组织形态学、宏观和放射学分析未显示对照组和 EP/EA 组之间的差异。仅在 EP 存在的情况下,EA 才导致 ABL 和 BRD 降低。EA 导致所有组中 IL-6 和 -17 的减少,但 NF-κB 仅在 EP 的关节炎大鼠中减少。总之,EA 减少了关节炎大鼠与牙周炎相关的炎症,但不能预防 ABL。我们的结果表明,EA 仅降低了关节炎大鼠的疼痛强度。组织形态学、宏观和放射学分析未显示对照组和 EP/EA 组之间存在差异。仅在 EP 存在的情况下,EA 才导致 ABL 和 BRD 降低。EA 导致所有组中 IL-6 和 -17 的减少,但 NF-κB 仅在 EP 的关节炎大鼠中减少。总之,EA 减少了关节炎大鼠与牙周炎相关的炎症,但不能预防 ABL。
