Abstract
樟芝為中國傳統中藥材,其所含多醣體曾被廣泛研究具調控免疫機制等各種生物功能,但目前並未有樟芝多醣體對於敗血症及其伴隨出現的肺臟損傷相關的研究。因此,本研究將實驗分為動物及細胞實驗兩部分,分別探討樟芝多醣體對敗血症生物體及肺上皮細胞發炎反應之影響。動物實驗以盲腸結紮及穿刺手術誘發小鼠產生敗血症,於術後 0.5 及 1 小時,依不同組別分別從腹腔注射生理食鹽水、100 mg/kg BW 樟芝菌絲或子實多醣體各二次,並於術後 6 及 16 小時,收取血液、腹腔沖洗液、肺臟及脾臟做分析。與一般控制組 (NC)相較,敗血症小鼠不論是血漿或腹腔沖洗液中 IL-10、IL-6、TNF-α 及 MCP-1皆明顯上升。手術 6 小時後,會造成小鼠白血球數量急遽下降;給予樟芝子實多醣體即可明顯提升血液中白血球數量,並降低腹腔沖洗液中 IL-6 濃度。於術後 16 小時,不論是菌絲或子實多醣體均可有效提升白血球數量、降低肺臟 NF-κB 蛋白表現量和腹腔沖洗液及血漿中 IL-10、IL-6、TNF-α 等 Th2 細胞激素的濃度;但僅有樟芝子實多醣體可顯著增加腹腔沖洗液中 IFN-γ 的濃度。而於脾臟細胞激素基因表現方面,術後 16 小時,與生理食鹽水組比較,不論菌絲或子實多醣體均可有效降低 TNF-α、IL-10 及 IL-6 的 mRNA 表現。由肺臟組織切片染色結果,發現菌絲或子實多醣體皆可減輕肺泡損傷,其中以子實體效果較好。
細胞實驗以脂多醣 (LPS) 刺激人類呼吸道上皮細胞 (BEAS 2B) 造成發炎反應來探討樟芝多醣體介入的影響。研究結果發現,樟芝多醣體可減少多型核白血球 (PMNs) 遷移至 BEAS 2B 的數目,並降低 PMNs 和 BEAS 2B 促發炎激素及 IL-8、MCP-1 的產生量。本結果顯示樟芝多醣體可能藉由抑制細胞分泌 IL-8,進而減少 PMNs 遷移至 BEAS 2B 細胞層,達到保護肺臟的作用。本研究結果顯示,樟芝多醣體可經由調節免疫反應以減緩呼吸道上皮細胞及敗血症之發炎反應,並減輕肺臟組織損傷。
