The therapeutic effects of the olibanum, the resin of Boswellia serrata on inflammatory diseases have been reported. There are more than 200 active ingredients in this resin including acetyl-11-keto-β-boswellic acid (AKBA). We proposed that AKBA can improve memory impairment induced by cerebral inflammation following the administration of lipopolysaccharide (LPS). Forty male rats were grouped and received the following treatments: Control (diluted DMSO + saline), LPS (diluted DMSO + 1 mg/kg LPS), LPS- AKBA 5 and LPS- AKBA 10 (5 or 10 mg/ kg AKBA before LPS). Morris water maze (MWM), passive avoidance (PA) and biochemical tests were carried out. Pre-treatment with both doses of AKBA improved memory performance in MWM and PA tests (P < 0.05 to P < 0.001). Pre-treatment by AKBA improved the levels of hippocampal IL-10 (P < 0.001), BDNF (P < 0.001), CAT (P < 0.05 and P < 0.001), SOD P < 0.001 and thiols (P < 0.01 and P < 0.001) while reduced IL-6 (P < 0.001), TNF-α (P < 0.001), NO (P < 0.05 and P < 0.001), GFAP (P < 0.001) and MDA (P < 0.001) levels. AKBA effectively ameliorated LPS-induced learning and memory impairments and improved BDNF in a neuroinflammation animal model. The effects seem to be due to setting a positive balance between pro-inflammatory to inflammatory cytokines and reinvigorate the antioxidant system.

乙酰-11-酮-β-乳香酸对脂多糖致大鼠脑细胞因子及记忆障碍的影响

乳香树脂、乳香树脂对炎症性疾病的治疗作用已有报道。这种树脂中含有 200 多种活性成分,包括乙酰-11-酮-β-乳香酸 (AKBA)。我们提出AKBA可以改善脂多糖(LPS)给药后脑炎症引起的记忆障碍。四十只雄性大鼠被分组并接受以下治疗:对照(稀释的 DMSO + 盐水)、LPS(稀释的 DMSO + 1 mg/kg LPS)、LPS-AKBA 5 和 LPS-AKBA 10(LPS 前 5 或 10 mg/kg AKBA )。进行了莫里斯水迷宫(MWM)、被动回避(PA)和生化测试。在 MWM 和 PA 测试中,用两种剂量的 AKBA 进行预处理都改善了记忆性能(P < 0.05 至 P < 0.001)。AKBA 预处理提高了海马 IL-10 的水平(P < 0.001),BDNF (P < 0.001)、CAT (P < 0.05 和 P < 0.001)、SOD P < 0.001 和硫醇 (P < 0.01 和 P < 0.001) 同时减少 IL-6 (P < 0.001)、TNF-α (P < 0.001) 0.001)、NO (P < 0.05 和 P < 0.001)、GFAP (P < 0.001) 和 MDA (P < 0.001) 水平。AKBA 在神经炎症动物模型中有效改善 LPS 诱导的学习和记忆障碍并改善 BDNF。这些效果似乎是由于在促炎细胞因子和炎症细胞因子之间建立了正平衡,并重振了抗氧化系统。AKBA 在神经炎症动物模型中有效改善 LPS 诱导的学习和记忆障碍并改善 BDNF。这些效果似乎是由于在促炎细胞因子和炎症细胞因子之间建立了正平衡,并重振了抗氧化系统。AKBA 在神经炎症动物模型中有效改善 LPS 诱导的学习和记忆障碍并改善 BDNF。这些效果似乎是由于在促炎细胞因子和炎症细胞因子之间建立了正平衡,并重振了抗氧化系统。
