201000108 六、發明說明: 【發明所屬之技術領域】 、本U係關於寡醣’特別為不可消化的寡醣組成物用於發 人特别為腸道發炎之預防或治療之用途。該組成物包含半 乳寡糖混合物。半乳寡料於不可消化的碳水化合物,可對 抗翁礼動物月腸道的消化酶,但可被特定大腸細菌所發酵。 【先前技術】 ❹人類之腸菌叢包合致病性、良性及有益性微生物種屬。大 部分的致病性微生物皆可能導致腸道病症,包括急性病症 (例如腸胃炎)及慢性病症(例如發炎性腸病及若干腸道癌 症)。曾經試圖藉添加一種或多種此等微生物菌株之適當食 物載媒劑來㈣腸g蟲的平衡而有利於有益的微生物,諸如 雙叉才干菌(bifidobacteria)。此種活的微生物食物補充物稱作 為1生菌但難以保證活ϋ於食物中以及於消化後存活。 〇 3 -種藉勝食操控腸道微菌叢的辦法係使用益生物質 (prebiotic) ’其係定義為不可消化的食物成分,其經由選擇 性刺激大腸中-種細菌或有限數目細菌的生長及/或活性, 藉此導致宿主健康的改善,因而對宿主造成有益的影響。 於多種發炎病症諸如發炎性腸病(IBD),益生物質顯示有 間接保護效果。發現於若干IBD病人適應性免疫系統對共 棲共生的腸卤叢有南度反應性(參考Guarner F,Malagelada JR,Best Pract. Res. Clin. GatroeTiternl.. (2003) ; Π_ ; 098117646 3 201000108 793-804)。結果,已經使用益生物質來增強有益的腸道微菌 叢,協助預防疾病的復發(參考Sartor RD.,Gastroenterology, (2004), 126, 1620-1633)。 有一類被歸類為益生物質的化合物為半乳寡醣。其為Glc 卢l-4[Gal/31-6]nB式其中n=2-5之含半乳糖之寡醣,係使用 酵素失半乳糖苷酶之轉半乳糖基酶活性而由半乳糖糖漿製 造(Crittenden, (1999)Probiotics : A Critical Review,Tannock, G. (ed)Horizon Scientific Press,Wymondham 141-156 頁)。 EP 1 644 482揭示一種新穎雙叉乳酸桿菌(Bifidobacterium bidifum)菌株,其產生半乳糖苷酶活性而將乳糖轉化成半乳 寡醣。此種半乳寡醣混合物顯示具有益生物質的性質,可增 加益菌雙叉桿菌及乳桿菌(lact〇bacilli)之族群。 今曰出乎意外地發現EP 1 644 482揭示之包含半乳寡醣 混合物之組成物可直接調節哺乳動物腸黏膜之發炎反應。特 別,可於發炎劑存在下減輕發炎前期化學激素反應。 【發明内容】 根據本發明’提供一種用於發炎之預防或治療較佳係用於 腸發炎病症之預防或治療之益生物質組成物。 ϋ生物質組成物為半乳寡醣混合物。此種混合物包含雙餹
