To study the changes of plasma endotoxin NO and hemorheology in experimental cirrhotic rats and their correlation,we have used hemorheology analysis system and the means of limulus amoebocyte lystata assay Griess assay to detect changes of plasma endotoxin NO and hemorheological parameter in rats at 3 6 9 weeks after CCl4 administration.

为探讨肝硬化中血浆内毒素、NO水平的变化及血液流变学特性的改变及其相互关系，我们通过用四氯化碳(carbon tetrachloride，CCl_4)来诱导大鼠肝硬化模型，采用鲎试剂动态浊度法、镉还原比色法、血液流变学分析仪，分别检测了大鼠肝硬化演变过程中早期(诱导第3周末)、中期(诱导第6周末)、晚期(诱导第9周末)的血浆内毒素、NO水平及血液流变学各参数。

The chromosome composition of Yuan Zhong 2, a common wheat-Ag.intermedium partial amphiploid (2n=54), was analyzed with the genomic in situ hybridization,in which the biotinylated total DNA of Ag.intermedium as the probe and the total DNA of common wheat cv.Chinese Spring as blocking DNA were used to hybridize with the chromosome DNA of Yuan Zhong 2 at mitotic metaphase in root tip cells.

为分析普通小麦-天兰冰草部分双二倍体-远中2号(2n=54)的染色体构成，用生物素(biotin-16-dUTP)标记天兰冰草染色体组DNA作为探针，以普通小麦品种中国春染色体组DNA为封闭DNA，与远中2号的有丝分裂中期染色体DNA进行了分子原位杂交。

This is the amphitheater of Herodes. It was made in the middle of the 2nd Century, after Christ.

By comparing the activity of theα-amylase and the soluble acid invertase in the kernel and the pedicel, the trend of theα-amylase activity in the kernel and the pedicel showed a peak, theα-amylase activity was high in the early stage, it could promoted amylolysis, supply the nutrition for the kernel development; theα-amylase activity was low in the rapid filling stage, it was in favorable to the starch accumulation.

通过比较籽粒和小穗柄中α-淀粉酶和可溶性酸性蔗糖转化酶的活性表明，籽粒和小穗柄中α-淀粉酶活性均呈单峰变化趋势，籽粒发育早期α-淀粉酶活性较高，可以促使淀粉转化，为籽粒的早期的发育提供营养物质；籽粒发育中期为快速灌浆期，淀粉酶活性较低，利于淀粉的积累。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
