There are four kind of isoforms of endothelin in human and other mammals named ET-1, ET-2, ET-3 and ET-β, which are slightly different in construction and pharmacological effect. In human beings, ET-1 is the dominative subtypes. ET-1 remains in blood at a low level about 5ng per liter on physical state. It is synthesized, stored, released and metabolized locally. The half-life of ET-1 is about 1 hour. ET-1 is the most potent vasoconstrictive factor till now, and it is more functional in vein than in artery. In vascular bed, there are two kind of ET receptors. Type A mainly located in smooth muscle cells, whereas type B in endothelial cells. The latter can stimulate intimal hyperplasia via a parasecretion way and activate some oncogenes such as c-fos and c-myc and then enhance their expression. These alterations result in constriction of blood vessels, thus the SMC steps into proliferate state from silent state.

人及哺乳动物体内有四种结构及药理学性质略有差异的异物体，分别为ET-1、ET-2、ET-3、ET-β，而在人主要是ET-1，在生理条件下，ET-1在血浆中含量较低，约为5ng〓，故ET-1不是一个循环激素，而是局部合成释放，局部起作用的活性物质，半衰期约1小时，ET-1是目前已知的最强的血管收缩剂，对静脉的作用比动脉强，在血管床，ET受体有A、B两型，A型主要分布在平滑肌细胞，B型主要分布在内皮细胞，它可以通过旁分泌途径刺激内膜增生，具有有丝分裂原效应，可以激活某些癌基因如C-fos、C-myc使其表达增强引起血管收缩，使静止期SMC进入增殖期，还可以通过信号传导途径，与bFGF、GTF-β、PDGF等生长因子协同作用，起共有丝分裂原作用。

It is found that there is a co-relationship between the boron isotope and chemical composition of magmatic tourmaline: the δ〓B value increases with increasing Al and Li in Y-site of tourmalines. The low δ〓B values (-41. 1～-39. 01‰) in Altay No. 3 pegmatite, which is one of the lowest values found by now, imply that non-marine evaporites might exist in magma source, or the pegmatitic magma had been assimilated by them during its intrusion and emplacement.

阿尔泰3号伟晶岩最初形成的结构带中电气石的B同位素组成是目前所发现的最低值之一(-41.11～-39.01‰)，指示形成伟晶岩脉的初始岩浆可能由含非海相蒸发岩的泥质岩经变质深熔作用形成，或是伟晶岩岩浆在上侵定位过程中同化了含非海相蒸发岩地层的结果。

There are many high risk factors of recurrence and death after resection of stage B large intestinal cancer patients.The main factors influencing the long-term survival of stage B large intestinal cancer patients are bowel obstruction,tumor necrosis,and perineurial invasion.

B期大肠癌切除术后复发和死亡的高危因素较多，影响其长期生存的因素主要是肠梗阻、肿瘤坏死和神经囊膜侵润，而与其它因素关系不大。

Levels of expression significantly increased after day 4 posttransplantation and persisted through the whole course of rejection, but levels of expression were obviously lower in the peripherial blood than those in portal vein blood. In contrast, the control group showed no expression of mRNA for perforin and granzyme B in portal vein and peripherial blood.

结果 急性排斥肝移植组术后3天门静脉和外周血中均有穿孔素和颗粒酶B基因mRNA表达，4天后表达明显增强，并贯穿整个排斥反应的全过程，但外周血表达的强度明显较门静脉血为弱，同基因对照组术后14天内无穿孔素和颗粒酶B基因表达。

Methods Ampicillin inhibitionof E. coli Top10 pcs+ was tested at first, and then b-lactamase activity in periplasm was examined.

然后再使用抗生素抗性分析、b-内酰胺酶的酶活测定以及Western blot杂交技术，分析质粒编码的b-内酰胺酶从细胞质到细胞间质的分泌情况。

Western blotting confirmed that the low activity of b-lactamase in E. coli Top10 pcs+ resulted from a lower amount of b-lactamase in its periplasm.

由此可见，周质内低含量的b-内酰胺酶是导致E.coli Top10 pcs+细菌氨苄青霉素抗性降低的原因。

Vibrio cholerae adherence to and colonization in the small intestine are essential step in the pathogenesis of cholera. At least one type of pili, known as TcpA, is required for the colonization process. This paper reports the electron microscopic evidence showing that V. cholerae 01 and 0139 serogroups can express at least 4 types of pili when incubated at 28℃ on AKI agar or CFA (pH6.8). Among the four types, three can be expressed by classical and El Tor strains of Vibrio cholerae 01: TcpA pili are peritrichous,being 7-8nm in diameter, 5-10μm in length, and form bundles of parallel undulating filaments of 0.5-0.8 μm wide and 10-15μm long; Type B are 3-4nm in diameter, up to 2μm long, and of wavy morphology; Type C are 7-8nm wide and 0.5-0.8μm long.
