This research evaluated the protective role of a combined extract of and (DBZO) against respiratory dysfunction caused by particulate matter (PM) exposure in BALB/c mice. The bioactive compounds identified in the DBZO are catechin, astragalin, 6-gingerol, 8-gingerol, and 6-shogaol. DBZO ameliorated cell viability and reactive oxygen species (ROS) production in PM-stimulated A549 and RPMI 2650 cells. In addition, it significantly alleviated respiratory dysfunction in BALB/c mice exposed to PM. DBZO improved the antioxidant systems in lung tissues by modulating malondialdehyde (MDA) content, as well as levels of reduced glutathione (GSH) and superoxide dismutase (SOD). Likewise, DBZO restored mitochondrial dysfunction by improving ROS levels, mitochondrial membrane potential, and ATP production. Moreover, DBZO modulated the levels of neutrophils, eosinophils, monocytes, and lymphocytes (specifically CD4, CD8, and CD4IL-4 T cells) in blood and IgE levels in serum. DBZO was shown to regulate the c-Jun N-terminal kinase (JNK) pathway, nuclear factor kappa B (NF-κB) pathway, and transforming growth factor β (TGF-β)/suppressor of mothers against decapentaplegic (Smad) pathway. Histopathological observation indicated that DBZO mitigates the increase in alveolar septal thickness. These findings indicate that DBZO is a promising natural agent for improving respiratory health.
本研究评估了 和 (DBZO)的联合提取物对BALB/c小鼠暴露于颗粒物(PM)所引起的呼吸功能障碍的保护作用。在DBZO中鉴定出的生物活性化合物有儿茶素、黄芪苷、6-姜酚、8-姜酚和6-姜烯酚。DBZO改善了PM刺激的A549和RPMI 2650细胞的细胞活力和活性氧(ROS)生成。此外,它显著减轻了暴露于PM的BALB/c小鼠的呼吸功能障碍。DBZO通过调节丙二醛(MDA)含量以及还原型谷胱甘肽(GSH)和超氧化物歧化酶(SOD)水平,改善了肺组织中的抗氧化系统。同样,DBZO通过改善ROS水平、线粒体膜电位和ATP生成,恢复了线粒体功能障碍。此外,DBZO调节了血液中中性粒细胞、嗜酸性粒细胞、单核细胞和淋巴细胞(特别是CD4、CD8和CD4IL-4 T细胞)的水平以及血清中IgE水平。DBZO被证明可调节c-Jun氨基末端激酶(JNK)途径、核因子κB(NF-κB)途径和转化生长因子β(TGF-β)/抗五聚体母系抑制因子(Smad)途径。组织病理学观察表明,DBZO减轻了肺泡间隔厚度的增加。这些发现表明,DBZO是一种有望改善呼吸健康的天然药物。
