In this study, BADH, gene encoding the key enzyme in betaine biosynthesis, which was isolated from Atriplex hortensis, and SeNHX1, a vacuole Na+/H+ anitiporter in Salicornia europhaea L., were used to transform the tobacco to improve the salt tolerance.

本研究拟用耐盐性较强植物山菠菜中的甜菜碱合成关键基因BADH和盐生植物盐角草的液泡膜Na+/H+ anitiporter基因SeNHX1对模式植物烟草进行转化，以确定其各自在耐盐性方面所起的作用。

The results showed the autotetraploid and triploid cultivars had lower cold resistance than that of diploid under the condition of 12℃ temperature and 1000Lx. With the increase of stress time, the SOD and POD activities of three ploidy cultivars were gradually increased.

低温胁迫对不同倍性西瓜叶片膜脂过氧化及保护酶的影响：通过对蜜枚西瓜幼苗进行低温弱光处理（12℃，光强为10001x，光/暗处理时间为14h/10h）的试验结果表明，在没有冷诱导时M4x、M3x的耐冷性不如M2x。

HPCA was measured by using a one-stage plasma recalcification clotting time.Results The peripheral blood lymphocytes from rheumatic carditis patients can stimulate the procoagulant activity of human heart tissue cell in vitro.But the sera of rheumatic carditis patients and group A streptococcal cell membrane can not increase HPCA.

结果 患者的外周血淋巴细胞能使HPCA明显升高；静止期风心病、风湿性关节炎、其他疾病对照组及健康对照组患者的外周血淋巴细胞均无此特性，迁延活动型风湿性心脏炎患者的血清及A组乙型溶血链球菌膜抗原对HPCA也无直接影响。

Based on the sensitivity, the co-existence and the ergodicity of chaos system, two new methods of chaos control are presented.

本文利用混沌系统的敏感性、共存性及各态历经性，提出控制混沌的两个新方法，并应用控制方法控制油膜轴承-柔性转子系统的混沌运动。

Because the cell membrane is lipoid, lipid-soluble drugs diffuse more rapidly than relatively lipid-insoluble drugs.

由于细胞膜为类脂质，脂溶性药物的扩散比相对的非脂溶性药物更快些，小分子的透膜速度也要比大分子快。

Because the cell membrane is lipoid, lipid-soluble drugs diffuse more rapidly than relatively lipid-i oluble drugs.

由于细胞膜为类脂质，脂溶性药物的扩散比相对的非脂溶性药物更快些，小分子的透膜速度也要比大分子快。

Therefore, it is convincible that of the distribution of the graft-chains in the PEM is quite even.

达到了本课题预期要解决的接枝链分布均一性和膜的平整性问题的目标。

Wheel' pattern were shown around mixed fibrous filter membranes, number of vessel ramification was 112.5±11.31 and ratio of vessel area/CAM area was 6.19±1.29﹪, but there were not localized allantoic vessels developing in the control group, the number of vessel ramification and ratio of vessel area/CAM area in control group were 82.6±8.05 and 1.78±0.33 respectively, so there was significant difference between PMP and control groups. In above mentioned conditions, the number of vessel ramification and ratio of vessel area/CAM area in VEGF group were 128.4±10.02 and 7.44±1.36 respectively, so there was no difference between PMP and VEGF groups.

结果显示：当 PMP的浓度为80 μg/ml时，孵育72小时后混合纤维素滤膜周围可见到放射状密集生长的血管网，血管分支数为112.5±11.31 ，血管面积为（6.19±1.29）﹪，而在对照组无特异性密集血管生成，血管分支数为82.6±8.05，血管面积为1.78±0.33，二组比较有显著性差异（P＜0.05）；而与VEGF组比较，后者的血管分支数为128.4±10.02，血管面积为7.44±1.36，二组比较差异无显著性。

We have successfully attained the fulllength cDNA sequence of FRG4, bioinformatic analysis shows FRG4 gene has 99%homology with Homosapiens synapse associated protein 1 (SYAP1), consists of 9 exons and 8 introns and located in Xp22.2. None transmembrane domains but a BSD domain was discovered, and its encoding protein is probably a water-solubility protein.

结果表明cDNA文库基础上运用热启动PCR获得FRG4全长cDNA序列，生物信息学分析显示FRG4基因与人类的突触相关蛋白有99%同源性；定位在X染色体的短臂2区2带2亚带2次亚带；由9个外显子和8个内含子组成；无跨膜区段；有一结构域BSD；该基因编码蛋白可能为一水溶性蛋白。
