摘要:
背景: patchouli hollic(pa),一种与Pogostemon cablin Cablin cablin Cablin隔离的自然化合物,已据报道具有抗议活动。但是,尚未研究PA对脂多糖(LPS)诱导的急性肺损伤(ALI)的影响。在本研究中,我们在体内研究了PA对LPS诱导的ALI的影响。
方法: 小鼠在胸腔内用LPS施用LPS来诱导肺损伤。 PA被管理lly 1 h before or after the LPS challenge.
RESULTS: The results showed that PA significantly decreased the wet-to-dry weight ratio of lungs and the number of total cells, neutrophils, and macrophages in bronchoalveolar lavage fluid at 7 h after the LPS challenge.此外,PA还抑制了炎性细胞因子的产生,例如肿瘤坏死因子-α,白介素1β和白介素-6在支气管肺泡灌洗液中。 Furthermore, Western blot analysis showed that PA inhibited the phosphorylation of IκB-α andp65 nuclear factor κB (NF-κB) induced by LPS.
CONCLUSIONS: Our results suggest that the anti-inflammatory effects of PA against LPS-induced ALI may be due to its ability to抑制NF-κB信号传导途径。
