Previous studies by others and this laboratory on the allosteric effect of hem oglobins have suggested that the electrostatic replusive cavity at the center of tetrameric moiety plays a substantial role in regulating O2 transport prope rties, including chloride binding, and Bohr effect .

中文摘要过去对血红蛋白异位调节效应的研究指出，在血红蛋白四合体中央空腔的区域的静电排斥效应对分子机能的调节如氧合时氯离子的键结和波尔效应，扮演著一个很重要的角色。

In attempt to obtain a further insight into the contribution of charged residues to other allosteri c properties , in this study we designed and synthesized a site directed mutan t , b82 Lys-Asn , for examing influencs the tetrameric stability and enthalpit ic change in O2 binding of human adult hemoglobin.

本研究焦点放在血红蛋白中央空腔中，带有正电残基的其中一个位置，b82 Lysyl ，来研究其正电离子效应与人类血红蛋白氧合反应热及四合体安定性的相关。针对这个目标，我们利用电脑做胺基酸序列排列比对和分子结构的模拟，选择以Asparaginyl残基取代Lysyl残基。

By O2 equilibrium, gel permission chromatography, and autooxidation analyses, we have investigated that the pos itively charge of b82 Lysyl residue is indeed involved in the exhothermic O2 b inding characteristics and somewhat stabilize the tetrameric heme moiety of Hb A.

其纯度以可见光谱和血色素电泳鉴定，并以氧合平衡曲线的测定，胶质层析和氧化速率的分析检视重组血红蛋白之性能。实验结果显示β82Lysyl残基所带的正电性确实影响血红蛋白氧合时的放热反应与其四合体的安定性。

HbJ Tashikuergan was firstly reported in the world, and CD8and CDs8/9 were firstly discovered in China.Conclusion:The types and distribution of abnormal hemoglobin and thalassemia in Kashi district were? different from those in other areas of our country,and also unsimilar to our neighbour countries.

对喀什地区血红蛋白病的研究表明，异常血红蛋白和地中海贫血的类型特点既有别于我国其它地区，又与邻近的中亚等国不完全相同，形成了该地区独有的遗传特征。

Compared with the surface-dwelling rodents, the higher RBC, HGB and HCT as well as lower MCV, MCH and MCHC in Gansu Zokor have possible roles in their adaptation to hypoxia environment.

与地面生活的啮齿动物低氧适应后血象相比，甘肃鼢鼠红细胞数量多，红细胞压积大，血红蛋白浓度高，红细胞膜表面积大，血红蛋白的利用率较高，可能是对低氧环境适应的一种途径。

The most popular technique utilizes blood oxygenation level dependent contrast, which is based on the different magnetic properties of oxygenated and deoxygenated blood.

其中基于氧合血红蛋白和脱氧血红蛋白的磁化率差异的血氧水平依赖性对比度的fMRI 技术在脑功能的研究中已经成为一种最重要的工具。

NIRS has shown great potential in examining functional brain activity during cognitive tasks by enabling an independent measurement of changes in the concentration of the oxygenated hemoglobin (HbO2) and the deoxygenated hemoglobin in cortex tissue based on differential absorption at multiple wavelengths.

基于氧合血红蛋白(HbO_2)和脱氧血红蛋白对多个波长的近红外光的不同吸收，NIRS可以提供对脑组织中HbO_2和Hb浓度相对变化的独立测量，因而在大脑功能活动的检测领域表现出了巨大潜能。
