Our results indicated that (1) aortic rings with and without endothelium precontracted by NE to decreased pH induced a relaxation; aortic rings with and without endothelium to increased pH induced a contraction; there is no significant difference in presence and absence of endothelium .(2)NO levels had no significant change in isolated aortic rings presence and absence of endothelium to decreased pH and increased pH ;(3)sulfite levels in isolated aortic rings with endothelium reduced to decreased pH and increased pH. sulfite levels in aortic rings without endothelium had no remarkable change.

结果：①NE预收缩后，pH值降低对内皮完整和去除内皮胸主动脉血管环呈舒张作用；pH值升高对内皮完整和去除内皮胸主动脉血管环呈收缩作用；内皮完整组与去内皮组相比无显著性差异；②pH降低和升高对内皮完整和去除内皮血管环中NO含量无显著性影响；③pH降低和升高均可使内皮完整血管组织中亚硫酸盐含量减少，对去内皮血管中亚硫酸盐无显著性影响。

Our results indicated that (1)SO_2 derivatives could dose-dependently relax the isolated aorta rings with or without endothelium precontracted by NE, no difference was found for the rings with and without endothelium;(2)Levels of cAMP and 6-Keto(PGI_2) in isolated aortic rings were increased by SO_2 derivatives in a dose-dependent way, which were independent of endothelium;(3)SO_2 derivatives decreased cGMP levels in the rings, but not significantly; The decrease of cGMP levels was also independent of endothelium;(4)No changes of TXB_2 in rings with or without endothelium were observed;(5)Whether presence or absence of endothelium, cAMP/cGMP and 6-Keto/TXB_2 ratios were increased significantly.

结果：①SO_2衍生物对去甲肾上腺素预收缩的内皮完整和去除内皮的大鼠胸主动脉血管环均呈浓度依赖性舒张作用，且其张力变化在内皮完整与去内皮的血管环之间无显著性差异；②SO_2衍生物可引起血管组织中cAMP、6-Keto(即PGI_2)含量剂量依赖性增加，其增加程度与内皮无关；③SO_2衍生物对血管环cGMP含量呈降低趋势但在统计学上无显著意义，且对去除内皮血管无显著影响；④SO_2衍生物对去内皮或内皮完整血管环的TXB_2含量均无明显影响；⑤无论是否去除内皮，SO_2衍生物均可引起cAMP／cGMP和6-Keto／TXB_2比值显著升高。

After 5-7 days in the condition medium, the OPCs gradually differentiated into mature oligodendrocytes, which were characterized by the complex profile of"ramificated"or"cobweb-like"processes reticulating in their periphery.

在体外培养5-7天时OPCs逐渐定向分化为成熟的少突胶质细胞，镜下见其胞体呈圆形，胞体周围具有大量网状纤细突起，呈&分枝&状或&蜘蛛网&状分布于胞体四周。

The simulated results show that the AO exposures strongly affect the microstructures and properties of the two film materials. For instance, as the AO exposure increases, the mass loss increases, the surfaces of the two types of films roughens, the optical transmittance of Kapton and reflectivity of Kapton/Al mirror degrade, but the solar absorptance of kapton/Al films increases.

结果表明：两种材料的质量损失随原子氧暴露剂量的增加呈线性增大；原子氧暴露后，试样表面呈&地毯&状形貌，且随暴露剂量的增加粗糙度变大；Kapton薄膜的光谱透过率、Kapton/Al薄膜二次表面镜的光谱反射率随原子氧暴露剂量的增加而降低，Kapton/Al薄膜二次表面镜的太阳吸收比Δα随暴露剂量的增加而增大。

There was difference of malnutrition reduction among different minority g roups of Yunnan. However, the NPA aim for malnutrition reduction had not realize d up to 2000. Conclusion: Malnutrition is still a serious health problem in rura l children in Yunnan.

2 0余年来云南省儿童体格发育呈增长趋势，农村5岁以下儿童营养不良呈下降趋势，但下降幅度未达到国家NPA目标，5岁以下儿童营养不良仍是云南省农村儿童的主要健康问题。

The activity of CAT decreased after the appearance of silks on the cob and remained a relatively low level after the 5th day of silking.

吐丝后花丝的受精结实能力与POD活性呈显著的负相关，与CAT活性呈正相关关系。

In the many factors that influence the quality of CdS deposition, the surface roughness of substrata is the important one. Exactly, SnO〓/glass substrata are the best, the glass substrata are the better, and ITO/glass substrata are not good for deposition of CdS polycrystalline thin films.

值得一提的是，沉积在ITO玻片上的CdS膜多呈六方相，而沉积在玻片上的CdS膜多呈立方相：然而，采用真空蒸发法制备的CdS薄膜，无论衬底是玻片，还是ITO玻片，其沉淀相均为六方相。

Based on the practice of nectarine breeding,the systematical inheritance of peel tomenta, flesh color ,pollen fertility and flavor of parents and their hybridization offsprings was analysed.

结合油桃育种实践，对亲本、杂交后代的果皮茸毛、肉色、花粉育性、果实风味等性状进行了系统遗传分析，结果进一步证实了果皮茸毛、肉色、花粉育性3个性状各由1对等位基因控制，其中果皮有茸毛对无茸毛、白肉对黄肉、花粉可育对败育均呈完全显性，且这3对等位基因分别呈独立遗传，无互作效应；选择甜风味的品种作亲本，杂交后代出现甜油桃单株的比例较高。

The area and number of heavy tracheae for a SVB, mean area of a tracheae for a SVB, the area and number of tracheae for all SVB had a significantly positive correlation with PGG on CMS lines, while the area of a tracheae for a SVB which has tracheaes, the area for a SVB, volume, weight, water potential had a negative correlation with PGG on CMS lines.

不育系种子裂颖率与浆片单个小维管束的导管面积和数目、单个小维管束平均单个导管面积、整个小维管束的导管面积和数目呈极显著负相关，与浆片单个导管未退化小维管束单个导管面积、单个小维管束面积、体积、重量、水势呈显著正相关。

The phytic acid contents in brown rice and rice bran both had a significantly negative correlation with the protein content in rice, and a significantly positive correlation with the 1000-grain weight.

糙米和米糠中植酸含量与稻米蛋白质含量均呈显著的负相关，与千粒重均呈显著正相关。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
