When Shigella flexneri 2a 2457T is cultured at 30℃, it's phenotypically avirulent; when grown at 37℃, its virulence improves greately. There is clear evidence that the temperature-dependent expression of the virulence genes is controlled by H-NS protein.

痢疾杆菌在30℃时不具有侵袭力，37℃时毒力明显增强，已有的研究表明这种依赖于温度的毒力基因的表达受H-NS蛋白的调控。H-NS是一种重要的类核相关蛋白，在革兰氏阴性菌中普遍存在，能够调控大量基因的表达。

Comparison from the Germany isolate, phocine distemper virus type Ⅱ(PDV-2) and vaccine strain, the major difference is the long signal peptide domain while the mature protein exhibit high identity, and all of the 13 serine residues, four potential asparagine glycosylation sites and two hydrophobic regions supposed to affect the fusion function are completely identical. These data supports the view that F protein is more conservative than H protein in CDV.

三、犬瘟热病毒中国分离株囊膜糖蛋白基因免疫小鼠诱发的抗体应答经一系列步骤将CDV-YZ0101株的两囊膜糖蛋白基因定向导入真核表达载体pcDNA3.1中，DNA测序和酶切分析筛选阳性重组质粒克隆pcDNA-H和pcDNA-F，以重组质粒DNA和脂质体共转染COS-7细胞，用间接免疫荧光试验证实转染的COS-7细胞的胞浆中分别表达了CDV的H和F蛋白。

To prove the H-OLE1 coding for △9-fatty acid desaturase, DNA electroporation system of H. polymorpha was established, and genetic complementation test was conducted.

为验证H-OLE1基因的功能，建立了多形汉逊氏酵母DNA电穿孔实验系统，进行了遗传互补测验。

Polymorpha cells in low level and produced a 1. 5kb transcript. Transcription of the gene was slightly repressed by exogenous △9 UFA. The FAR element in S. cerevisiae OLE1 promoter described by Choi et al. might not be crucial for positive transcriptional regulation of H-OLE1 gene.

Northern杂交发现，H-OLE1基因在细胞中以较低水平表达，产生1.5kb的转录子；基因表达略受不饱和脂肪酸的抑制；在多形汉逊氏酵母H-OLE1基因的转录调节中，Choi等在酿酒酵母OLE1基因中发现的脂肪酸调节元件FAR可能不是关键的。

Lactated Ringer's or 7.5% NaCl+6% dextran 70 was given for resuscitation 6h postburn.The volumes and rates of fluid infusion were controlled basically on the urinary output of 1.0ml*kg-1*h-1 and cardiac output of 70%～80% of preburn values.The volume load,+dp/dtmax,-dp/dtmax,CI,DO2 and VO2 were obtained to evaluate the effect of HSD resuscitation. Results The resuscitated volume of HSD was 30.56% less during first 24h postburn and 59.50% less at 4h after resuscitation than LR's.

采用犬35%TBSA Ⅲ度烧伤模型，伤后6 h分别用乳酸林格液及HSD进行复苏，并以每h尿量为1.0ml/kg及心输出量为伤前值的70%～80%来调整输液速度及输液量，观察HSD在复苏中容量负荷、左心室等容收缩期最大压力变化速率及左心室舒张期压力下降最大变化速率、心脏指数、氧供给(DO2)及氧消耗(VO2)等的变化。

The results showed that 7-day-precultured embryogenic calli had the best responses for bombardment among 2-7 day' preculture duration. Enhanced transformation efficiency was found in the explants treated with high osmotic medium 4h prior to till 24 h after bombardment. Particles of gold and tungsten were both found suitable for rice transformation and there was no adverse effect when tungsten particles were reduced to 1/3 standard amount for DNA precipitation on transient GUS gene expression. However, it was found that gold particle had higher GUS expression at 120 h post-bombardment. A preliminary microprojectile transformation system with an average of 15-20 blue spots/explant GUS expression was routinely obtained for 'Tainung 67' by using the particle gun with 1,100 psi rupture disk, 6 or 9 cm microcarrier flight distance and 4 mm of macrocarrier flight distance setting.

初步结果显示，以预培养2~7日之胚性癒合组织逐日测试转殖率，以预培养7日之培植体表现最佳；培植体於转殖前4小时至转殖后24小时以高渗透压培养基处理，有助於转殖效率之提高；比较金、钨粒子对转殖率在转殖后48h並无不同，但转殖后120 h取样，则金粒子组有较高之蓝点数；钨粒子用量可减少至1/3標准用量对转殖率並无影响；利用基因鎗在使用1， 100 psi裂碟片、大载片至挡片之距离为4 mm、微载髁至射击目標之飞行距离6或9 cm之设定，GUS基因表现之平均蓝点数均可达15~20个／培植体。

H. who proses it away from morning to night, and never gets beyond corporal and material verities. When I can't sleep o'nights, I imagine a dialogue with Mr. H, upon a given subject , and go prosing on in fancy with him, till I either laugh or fall asleep.

他从早到晚地闲扯，从没离开过肉体和物质这些事情……当我晚上睡不着时，我想象与H先生谈话，就一个话题一直闲聊，直到我大笑起来或是睡着为止。

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.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
