摘要: 本试验旨在比较3种植物多糖对鸡外周血T淋巴细胞和脾脏B淋巴细胞体外增强免疫活性的研究.通过酶学检测法测定3种植物多糖对鸡胚成纤维细胞的安全浓度,MTT法比较3种植物多糖单独刺激和PHA协同刺激对鸡外周血T淋巴细胞增殖指数的影响,同时比较3种植物多糖单独刺激及与LPS协同刺激对鸡脾脏B淋巴细胞增殖率的影响.结果显示,黄芪多糖和桑叶多糖具有较高的细胞安全浓度,在64~512 μg/mL时,3种植物多糖对鸡外周血T淋巴细胞和脾脏B淋巴细胞的增殖作用较强.结果表明,3种植物多糖对鸡外周血和脾脏淋巴细胞都有不同程度的体外增殖作用,其中黄芪多糖的增殖作用最强,桑叶多糖其次,山药多糖最差.

Abstract: This experiment was aimed to compare immune enhancement activities of Astragalus polysaccharide (APS), Morus polysaccharide (MPS) and Chinese yam polysaccharide (CYPS) to chicken peripheral lymphocyte-T and spleen lymphocyte-B. The safe concentrations of the 3 polysaccharides to chicken embryo fibroblast were tested by enzymes detection method; the influence on proliferation of chicken peripheral lymphocyte-T by the 3 polysaccharides separate stimulating and coordinate stimulating with PHA were compared, the influence on proliferation of chicken spleen lymphocyte-B by the 3 polysaccharides separate stimulating and coordinate stimulating with LPS were studied. The results revealed that APS and MPS had higher safe concentrations. At 64 to 512 μg/mL, 3 polysaccharides showed excellent activity of promoting proliferation of peripheral lymphocyte-T and spleen lymphocyte-B. The results showed that the 3 polysaccharides had different influence on proliferation of chicken peripheral lymphocyte and spleen lymphocyte, and among them, the effect of APS was best, that of MPS was less, and CYPS was least.

Key words: polysaccharides; lymphocyte proliferation; phytohaemagglutinin (PHA); lipopolysaccharide (LPS)
