Abstract
根據調查全世界罹患過敏性疾病之盛行率有逐年增加的趨勢。過敏反應也被稱為第一型過敏反應,它主要特徵為體內有大量之IgE之產生,其發生主要和第二型輔助性T細胞、肥大細胞等活化有關。文獻曾指出山竹具有改善過敏症狀之功效,主要機制為抑制組織胺、血清素之產生。因此本研究主要目的為採用卵白蛋白所建立Balb/c小鼠之過敏模式並評估山竹粉末對於減緩過敏反應之能力。動物經三次致敏後,隨機分成四組,分別以管灌餵食方式給予過敏小鼠三種劑量山竹粉末介入(L, M, H組)。餵食28天後,將小鼠犧牲並取其血液及脾臟來進行分析。在建立過敏小鼠之結果顯示與注射OVA前血漿比較,注射OVA後血漿中總IgE, 總IgG, OVA-IgE, IgG1皆顯著高於注射前,表示此過敏模式已成功建立。山竹餵食結束之結果顯示,血漿中總IgE, 總IgG, OVA-IgE皆顯著低於控制組,而OVA-IgG1於L組則顯著低於控制組;OVA-IgG2a於L組顯著高於控制組。另外,在脾臟細胞增殖能力部分,給予裂殖素或過敏原刺激後,B細胞增殖能力顯著低於控制組。經ConA刺激後,IFN-γ之分泌於M、H組顯著高於控制組;IL-5之分泌皆顯著低於控制組。另外,經由OVA刺激後,IL-4之分泌於H組顯著低於控制組。整體而言,山竹可能透過調節Th2細胞激素以及B細胞增殖作用,降低過敏相關抗體之產生,進而達到改善過敏反應之能力。
