透膜性的

The wheat coleoptile is a good material to study plant elonggation growth because it is structurally simple and easy to get unifomal materials.

通过测定叶片的电导率发现，随Cu2+浓度的升高，膜透性大大增加，也证明了这一点。

Standard patch clamp methods were used to measure whole cell capacitance,zero current potential,reversal potential and potassium ion currents of Deiters′ cells in normal external solution.Equations were used to compute the relative membrane permeability ratio of Deiters′ cell to K+ and Na+ and the potassium equilibrium potential.

采用酶孵育加机械分离法分离Deiters细胞；利用膜电钳技术在全细胞模式下检测全细胞电容，记录在正常外液中的钾电流，零电流电位，反转电位，并根据相应公式计算离子通道K+与Na+的相对通透性比率及K+平衡电位。

The acid rain cause the cytoplasm, MDA content and praline content increase, the lower the pH values of simulated acid.

酸雨引起板蓝根种子的细胞质膜透性、丙二醛和脯氨酸含量上升，模拟酸雨的pH越小，这种生理反应就越明显。

By field experiments, seed yield, leaf proline,MDA and cell membrane permeability were studied in 8 different genotype corn varieties.

对 8个基因型不同的玉米杂交种，在不同供磷水平下的籽粒产量、叶片脯氨酸、丙二醛和质膜透性进行了研究。

According to analysis of salt tolerance indexes, it was obtained that salt inhibited seed germination and seedling growth along with the increase of salt concentration, the relative germination rate, germination index and relative simple activity index, seedling root length and plant height reduced gradually, membrane permeability of leaves increased.

结果表明，盐胁迫对燕麦种子萌发和幼苗的生长有抑制效应，而且随着盐浓度的增加，相对发芽率、发芽指数、简易活力指数、幼苗根长和株高逐渐降低，叶片质膜透性逐渐增加。

OBJECTIVE:To study the effect of ferulic acid sodium on the increase of the pial microvascular permeability induced by histamine.

目的：观察阿魏酸钠对组胺引起的脑软膜微血管通透性增加的抑制作用。

MDA content, cell division , he activities of NR, CAT, POD and SOD of Pistia sagittifolia and Myriophyllum Spicatum with heavy metal,s ion concentration to appear a trend of ascending firstly and desending secondly . This trend explains that Pistia sagittifolia and Myriophyllum Spicatum on the Toxic Effects have similarities under handing the single Pb2+ and Hg2+. As the range of the concentration which each index is arriving at the maximum is different, this also indicates that there are some differences of the Toxic Effects between Pistia sagittifolia and Myriophyllum Spicatum under handing the single Pb2+ and Hg2

丙二醛含量、脂膜透性、硝酸还原酶活性、过氧化物酶活性、超氧化物歧化酶活性、过氧化氢酶活性随重金属离子浓度的增加呈先升后降趋势，说明在单一Pb2+和Hg2+处理下大薸和穗状狐尾藻毒害效应具有相似性；但各指标到达最大值的浓度范围不同，又说明单一Pb2+和Hg2+处理下大薸和穗状狐尾藻毒害效应具有差异性。

Objective: To study the effect of satragaloside Ⅳ on the microvascular permeability induced by histamine in pial microvessels.

中文摘要：目的：观察黄芪皂苷甲对组胺引起的脑软膜微血管通透性增加的抑制作用。

The results showed that memberane permeability increased,POD and SOD activity and soluble protein content decreased in the Raphanus L.seedlings under 300 mg/L lead stress.

结果表明：在300 mg/L铅胁迫浓度下萝卜芽苗菜的膜透性明显增大，过氧化物酶活性、超氧化物歧化酶活性、可溶性蛋白含量明显下降。

The results showed that spring wheat with plastic film mulches was able to improve the content of chlorophyll and protein of leaves in the earlier growing period and the average increase per day of the content of chlorophyll and protein of the mulched wheat increased by 31.49% and 7.94% than that of unmulched wheat respectively; but it could accelerate the decomposition of chlorophyll and protein in the later period.

结果表明，采用地膜覆盖栽培方法，在春小麦生长前期能明显提高叶片叶绿素和蛋白质的含量（日均增加量分别比露地春小麦高31.49%和7.94%），但后期又会加速其降解速率；MDA含量和细胞质膜相对透性均表现为覆膜处理高于露地处理（日均增加量分别比露地春小麦高71.96%~11.78%和2.42%~9.57%）。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
