采用水提醇沉法提取刺玫根粗多糖,以Seva.e法和TCa.脱蛋白,进一步分级醇沉法分离纯化得到较纯的60%醇沉物(RDRP)进行结构鉴定和活性评价。苯酚浓硫酸法测定出刺玫根多糖RDRP总糖含量为94.1%;高效凝胶渗透色谱法测定表明主要含有重均分子量为13.1 kDa.相对分散度为1.2的多糖;通过高效离子色谱法和红外光谱测定,鉴定刺玫根多糖为由葡萄糖、阿拉伯糖、半乳糖、甘露糖、木糖等5种单糖组成的含有α-构型的中性吡喃多糖。环磷酰胺诱导的免疫抑制小鼠模型实验结果表明,与模型组相比,刺玫根多糖各剂量组小鼠的脾脏和胸腺指数明显升高(Pisa法检测血清中免疫相关蛋白igG、igM、iga.及细胞因子TNF-α、iFN-γ、iL-6与iL-2的分泌水平,结果显示,与模型组比较,刺玫根多糖组显著上调小鼠血清中免疫球蛋白iga.igG、igM浓度水平(PiL-2、iFN-γ、TNF-α、iL-6的含量(Pa.-6和NF-κB p65蛋白的表达水平,发现刺玫根多糖各剂量组脾脏中TLR4、TRa.-6蛋白极显著上升(P<0.01),高剂量组的MyD88蛋白极显著上升(P<0.01),其他组呈现上升趋势;刺玫根多糖各剂量组NF-κB p65蛋白均有上升趋势,因此其免疫调节作用机制可能与TLR/NF-κB通道有关。本研究初步阐明刺玫根多糖的基本结构特征和其免疫调节作用及其机制,为刺玫根多糖的开发应用提供一定价值的实验依据。

本研究以呼伦贝尔市典型草原为研究对象,通过传统地面样方调查和无人机调查,系统研究了“种-面积”关系,确定了典型草原地面与无人机调查的最小调查面积.调查结果表明:1)典型草原的物种数量与调查面积呈非线性关系,“种-面积”关系呈现为S=a.n(ba.1).基于组合样方法,至少要包括8个1m^(2)小样方,才能达到涵盖80%物种的目标,基于巢式样法,需要的最小调查面积为8.63m^(2);2)针对典型草原,无人机调查的平均物种发现率为传统地面调查方法的81.7%,无人机可作为地面调查的辅助手段,提高调查的效率;3)在典型草原物种监测中,可选取1个或2个组合样方,并使用无人机进行4~5次随机拍摄作为补充,此时可发现典型草原物种总数的84.7%~88.3%.该方法相对传统的3~5次重复样方调查,代表性更高,调查效率更高.
