Stachyose (STA) is extracted from sugar beet and is used as a functional food. In this study, the effects of STA on immunosuppressed mice with intestinal mucosal damage induced by cyclophosphamide (CTX) are investigated. STA treatment can improve the amount of the leukocyte in the blood, the bone marrow cell density, and natural killer (NK) cell activity in the immunosuppressed mice. Furthermore, in immunosuppressed mice, the balance of intestinal bacteria is broken and intestinal mucosal integrity is disrupted. After treatment with STA, the amount of Enterococcus (6.504 ± 0.70) decreases and Bifidobacterium (7.207 ± 0.14) in cecum increases significantly (< 0.05). Compared with CTX group, the ratio of villous height and crypt depth (V/C) in ileum increases from 2.525 ± 0.10 to 4.891 ± 0.16 (< 0.001), and in jejunum increases from 2.719 ± 0.03 to 5.827 ± 0.19 (< 0.001). The expression level of IL‐2 and IL‐1β gene in the spleen, and IL‐1β and tumor necrosis factor alpha gene in the ileum in STA group significantly increases (< 0.001) compared with the CTX group. In conclusion, STA is a potential prebiotic which exerts indirect and direct effects on the immune system and can counteract the side effects of CTX in the immunosuppressed mice.

水苏糖可预防免疫抑制小鼠的肠粘膜损伤

水苏糖(STA)从甜菜中提取,用作功能食品。在这项研究中,研究了STA对由环磷酰胺(CTX)诱导的肠粘膜损害的免疫抑制小鼠的影响。STA治疗可以改善免疫抑制小鼠的血液中白细胞数量,骨髓细胞密度和自然杀伤(NK)细胞活性。此外,在免疫抑制的小鼠中,肠细菌的平衡被破坏并且肠粘膜完整性被破坏。用STA治疗后,盲肠中肠球菌(6.504±0.70)的量减少,盲肠中的双歧杆菌(7.207±0.14)显着增加( <0.05)。与CTX组相比,绒毛高度与隐窝深度之比(V/ C)在回肠中从2.525±0.10增加到4.891±0.16( <0.001),而在空肠中从2.719±0.03增加到5.827±0.19( <0.001)。与CTX组相比,STA组脾脏中IL-2和IL-1β基因的表达水平以及回肠中IL-1β和肿瘤坏死因子α基因的表达水平显着增加( <0.001)。总之,STA是一种潜在的益生元,对免疫系统具有间接和直接的作用,并且可以抵消免疫抑制小鼠中CTX的副作用。
