目的 采用免疫低下小鼠模型研究鬼鲉肝脏提取物对免疫功能的影响。方法 采用环磷酰胺诱导建立免疫低下动物模型,免疫器官重量法测定胸腺指数和脾脏指数,碳粒廓清法测定小鼠单核巨噬细胞的功能,绵羊红细胞免疫法测定小鼠体液免疫功能,采用血细胞计数仪检测小鼠外周血常规,采用ELISA方法测定小鼠血清中TNF-a、IL-1b、IL-2、IL-6的水平,采用流式细胞仪测定脾细胞周期。结果 鬼鲉肝脏提取物可以减缓免疫低下小鼠体重的下降趋势,减少免疫低下小鼠脾脏和胸腺的损伤,促进免疫低下小鼠脾细胞的分裂和增殖,可以增加免疫低下小鼠单核巨噬细胞吞噬功能和血清溶血素含量,并且可以增加免疫低下小鼠白细胞数、中性粒细胞数、淋巴细胞数和单核细胞数和血清中TNF-a、IL-1b、IL-2、IL-6的含量。结论 鬼鲉肝脏提取物可以增强免疫低下小鼠的免疫功能,为综合利用鬼鲉这一生物资源提供了指引。 |
English Summary: |
Objective Influence of Inimicus japonicas liver extract on the immune function was investigated on the basis of immunosuppressed mice. Methods Immunosuppression animal model was established by cyclophosphamide induction. The immunity organs were weighed to measure the thymus index and spleen index; the clearance of charcoal particles method was used to measure mice’s mononuclear macrophages functions, and sheep red blood cells immunizations was used to measure mice’s humoral immune functions; mice’s blood counts was measured by blood-counter system, and Enzyme-linked Immuno Sorbent Assay (ELISA) was used to measured the TNF-a, IL-1b, IL-2 and IL-6 level in blood serum; the spleen cell cycle was measured by flow cytometry. Results Inimicus japonicas liver extract significantly improved the thymus index and spleen index, promoted the division and proliferation of spleen cells, improved the mononuclear macrophages functions, increased the hemolysin level of blood serum and the levels of leukocytes, neutrophils, lymphocytes and monocytes, and also increased the levels of TNF-a, IL-1b, IL-2 and IL-6 in blood serum. Conclusion Inimicus japonicas liver extract enhanced immunosuppressed mice’s immune function, which provided a direction for comprehensively utilizing the marine living resource. |
