Methods:IND01 was prepared from fenugreek seeds and standardized by high performance liquid chromatography to a marker compound,trigonelline.The effects of daily oral administration of IND01(50,100 and 200 mg/kg) were studied in rats after partial sciatic nerve ligation(PSNL) and sciatic nerve crush injury(SNCI) during 30-days period.The measurements on thermal hyperalgesia(TH),motor function test(MFT) score and motor nerve conduction velocity (MNCV) were recorded.Results:IND01 offered sustained protection against TH and deranged MFT scores in both models from 7-day onwards.Fifteen days of daily oral administration of IND01 restored MNCV reduction in rats with SNCI but not with PSNL.Conclusions:IND01 was found to be effective in rat models of painful peripheral neuropathy.展开更多

文摘为研究苜蓿属（Medicago L.）与胡卢巴属（Trigonella L.）间的亲缘关系,寻找两属间的分属依据,解决中间过渡类群的分类归属问题,对苜蓿属与胡卢巴属种类的种皮结构和花粉形态特征进行了观察和测量,并以苜蓿属和胡卢巴属植物的40个形态性状为依据、应用数量分类方法对供试的16个种类进行了聚类分析（UPGMA）和主成分分析（PCA）。此外,还根据具有重要分类学意义的形态性状,编写了供试的苜蓿属和胡卢巴属16个种类的分类检索表。观察结果表明,供试的两属植物（11种）的种皮结构基本相同,均由栅栏组织细胞、厚壁细胞和薄壁细胞组成,但胡卢巴属种皮的帽状结构和栅栏组织的厚度均小于苜蓿属。供试的两属植物（9种）花粉形态特征相似,均为椭球形或近球形,赤道面观为椭圆形,极面观为三裂圆形;极轴和赤道轴长分别为22.67~34.67μm和17.34~31.60μm;花粉表面纹饰较简单,呈小穴状。种皮结构和花粉特征显示两属的亲缘关系较近,仅种皮结构中的帽状结构差异具有一定的属间分类学意义。聚类分析结果表明,在欧氏距离10.85处,供试的苜蓿属（11种）和胡卢巴属（5种）的16个种类被划分为2组,A组均由胡卢巴属种类组成,B组均由苜蓿属种类组成;在欧氏距离9.32处,B组可被进一步划分为3个亚组,所包含的种类分别为苜蓿属的阔荚亚属（Subgen. Platycarpos D. F. Cui）、镰荚亚属（Subgen. Medicago Tutin）和天蓝苜蓿亚属（Subgen.Lupulina Gressh.）的种类。主成分分析结果表明,前3个主成分的累积贡献率较低,仅57.50%;在前3个主成分中,果实和小叶的长宽比、花萼长和被毛状况、茎和小叶的被毛状况、小叶尖形状、花序长等相关性状的绝对权重值均在0.6以上,具有重要的分类学意义;基于前2个主成分所做的二维散点图中供试的16个种类组成4个表征类群,与聚类分析结果一致。
