| 3. | In the past ten years , many studies have suggested that nitric oxide ( no ) may work as a nanc neurotransmitter , inhibiting motility of the gi tract 近十年来许多研究提示,一氧化氮( nitricoxide , no )很可能是作为nanc能神经的候选递质抑制胃肠道运动。 |
| 4. | Objectie . the aim of the present study was to inestigate the concentration of nitric oxide ( no ) in the perifacetal region in patients with chronic low back pain and healthy controls 目的:这项研究的目的是调查慢性腰背痛病人和正常人小平面关节中no的浓度。 |
| 5. | P450nor is a nitric oxide ( no ) reductase ( nor ) found in eukaryotic microorganisms , which reduces no to nitrous oxide ( n2 o ) by directly accepting electrons from nadh or nadph 细胞色素p450nor起着一氧化氮还原酶的作用,能以nad ( p ) h为直接电子供体将no还原成n _ 2o 。 |
| 6. | In 1980s that the free radical nitric oxide ( no ) might play a role in the brain of mammals , more and more people have paid close attention to the biological functions of no 20世纪80年代末一氧化氮( no )生物学作用的发现告诉我们一个全新的事实:一个细胞产生的气体信号可透过细胞膜调节另一个细胞的功能。此后, no的生物学作用受到人们越来越多的关注。 |
| 7. | Methods : in cultured lung explants without serum , the lipid component synthesis of pulmonary surfactant was evaluated in [ 3h ] - choline incorporation ; mrna content of phosphocholine cytidylyltransferase ( cct ) in lung explants was investigated in rt - pcr ; the changes of the ultrastructure of the at ii cells were observed with electron microscope ; the expression of nmdar1 subtype was observed in immunohistochemistry staining ; nitric oxide synthase ( nos ) activity , nitric oxide ( no ) content , superoxide dismutase ( sod ) level , malondialdehyde ( mda ) content and lactae dehydroase ( ldh ) level were determined by biochemistry methods . results : 1 . influence of glutamate on synthesis of the lipid component of pulmonary surfactant ? with l - arginine , glu inhibited [ 3h ] - choline incorporation with good dose - dependence and time - dependence ; ( 2 ) mrna content of cct of the glu treatment groups was decreased ; ( 3 ) glu increases the release of ldh in cultured lung explants ; ( dwith electron microscope histochemistry , glu induced the changes of the ultrastruture of at ii iv cells 方法:采用成年大鼠肺组织无血清培养,运用[ ~ 3h ] -胆碱掺入法测定ps主要脂质磷脂酰胆碱( pc )合成量; rt - pcr扩增检测肺组织中pc合成限速酶磷酸胆碱二胞苷酰基转移酶( cct ) mrna含量;透射电子显微镜法观察肺泡型上皮细胞和ps系统超微结构的变化;免疫组织化学染色检测glu的受体nmdar1亚单位的表达;生化测定肺组织乳酸脱氢酶( ldh )释放量和肺组织匀浆中一氧化氮合酶( nos )活性、一氧化氮( no )生成量、超氧化物歧化酶( sod )水平以及丙二醛( mda )含量。 |
| 8. | Objective to study acute myocardial ischemia , 70 rats had been used to produce myocardial ischemia . nitric oxide ( no ) had been measured in plasma . endothelin ( et ) and nitric oxide synthase ( nos ) had been studied with immuno - histochemical technique and an image analyzer , we wish to find sensitive methods for forensic identification of acute myocardial ischemia 目的观察大鼠急性心肌缺血模型早期正常区、交界区和缺血区心肌的病理改变, et和nos的表达和血浆no浓度的变化,试图为急性心肌缺血猝死的法医病理学鉴定提供客观的形态学依据。 |
| 9. | It has been well known that vascular endothelial cells ( vec ) are not only a mechanical and biological barrier of blood vessels , but also an endocrine organ , which maintain vascular normal tension and reactivities througth synthesis and release vasoactive substances such as nitric oxide ( no ) 研究发现,血管内皮细胞( vascularendothelialcells , vec )能合成多种血管活性物质,是维持血管正常张力状态和血管反应性的关键因素。其中vec释放的一氧化氮( nitricoxide , no )是人们发现的机体第一种气体信使分子,具有明显的血管活性、介导了血管内皮依赖性舒张反应。 |
