Abstract
台灣面臨高齡化社會的挑戰,將需要照顧越來越多的高齡失能患者。由於長期臥床,這些患者的口腔衛生和義齒清潔經常被忽視,導致齲齒、牙周病和口腔念珠菌感染等問題。而乾口症缺乏唾液潤滑和抑菌作用,容易導致潰瘍、灼燒感、吞嚥困難和細菌滋生。尤其是高齡者和療養機構居民,誤嚥和吞嚥困難的情況十分常見,這可能引起呼吸道感染和吸入性肺炎等嚴重併發症,並導致高死亡率。因此,本研究旨在利用無患子純露 (Sapindus mukorossi hydrosol, SMH)來對抗口腔致病菌和抗發炎,以改善口腔健康,預防相關疾病,並降低肺炎的發生率和死亡率,特別是吸入性肺炎。
為研究無患子種仁應用在口腔中的可行性,利用無患子種仁萃取成純露後,以人體肺臟腫瘤細胞 (Human lung cancer cell, Calu-3)作為實驗模型,細胞經SMH處理,經MTT Assay檢測細胞活性最高增加28.6%。經暴露LPS (0.1ug/ml)致細胞發炎後,ELISA檢測IL-6分泌量減少45.8%,IL-8分泌量減少8.4%。
致口腔與呼吸道相關疾病之致病菌的抗菌率:肺炎鏈球菌99.76%、伴放線聚集桿菌99.98%、牙齦卟啉單胞菌99.99%與變異鏈球菌99.89%。
小鼠飲用SMH後,在小鼠腹腔注射LPS後致使肺臟發炎,並製作肺臟組織切片,在SMH的介入下,肺泡壁的腫脹程度有顯著改善,肺泡空間佔比提高15.16%。
經上述實驗結果證實SMH確實具有抗菌及抗炎之效果,且並無生物毒性,可預防齲齒、牙周炎與口臭等疾病,確立SMH在口腔中應用的基礎,而動物實驗證實肺臟發炎反應被成功抑制,未來或許可作為日常肺部或口腔保健保養及抑制發炎反應之藥物,水性質地可作為藥物溶劑,改善人工唾液之抗菌性能有潛力在未來作為口腔保健/殺菌劑與肺部炎症治療吸入劑。
