通气组织

Developed aerenchyma tissue could restrain significantly the As translocation from root to shoot in rice plant and the As accumulation in rice shoot.

发达的通气组织结构显著抑制了As由水稻地下部到地上部的转运以及地上部对As的吸收：扬稻6号地上部As含量为10.77mg·kg-1，显著低于农垦57（12.85mg·kg-1）；扬稻6号对As的转移系数为0.067，仅为农垦57的73.6%。

In nutrient solutions,deoxygenation caused a series of changes in root ana-tomy of some species,such as increased root diameter,root porosity and more developed aerenchyma,inducing a ROL barrier in root basal part and the consequent change of ROL profile.

溶液培养条件下，缺氧胁迫能使植物根的直径增粗，根孔隙度提高，通气组织更加发达，诱导根基部泌氧屏障的生成，使泌氧速率和泌氧方式发生变化。

Five days following hormone additions, we obtained transverse sections of mid-stems of A. anomala and S. variegata and analyzed aerenchyma formation using E80i Nikon microscope, ACT-2U and Simple PCI software.

处理5 d后，采用切片法制备其茎中部横切面切片，用E80i Nikon显微镜进行观察，并运用ACT-2U和Simple PCI软件分析野古草和秋华柳茎中通气组织的形成情况。

Changes of lung ultrastructures: The results of electron microscope showed that in group 1, there were swelling mitochondria was arranged in disorder, less matrix, and hyalomere appeared, thin double-deck membrane in 50% samples: Interalveolar septum stroma was with edema in 60% samples; Polymorphonuclear leukocyte gathered in vessel or emigrated out of vessel in 50% samples; In group 2, double-deck membranes of mitochondria were integral, densely matrix showed micro-granule shape in 90% samples; Pinocytosis in epithelial cells of type Ⅰ lung strengthened, being destroyed, and pinocytosis in endothelial cells strengthened in 10% samples; lnteralveolar septum stroma was with edema, no polymorphonuclear leukocyte gathered in vessel or emigrated out of vessel or corpuscule was empty in type Ⅱ alveolar epithelium in 20% samples.

肺组织超微结构改变观察：纯氧机械通气组50%标本线粒体肿胀、排列紊乱，基质变浅，出现透明区，双层膜变薄，60%标本肺泡隔间质水肿，50%标本多形核白细胞血管内聚集或游出血管外现象；34%氧浓度机械通气组90%线粒体双层膜较完整，基质致密呈细颗粒状；10%标本可观察到Ⅰ型肺上皮细胞有吞饮增强、破坏及内皮细胞吞饮增强；20%标本肺泡隔间质水肿；未见到多形核白细胞血管内聚集或游出血管外现象及Ⅱ型肺泡上皮板层小体排空。

Objective］ The purpose was to research the formation and change of aerenchymas in the stems of Arundinella anomala and Salix variegate seedlings treated by different continuous waterflooding times and depths.

［目的］研究在不同连续水淹时间和水淹深度处理下，野古草和秋华柳幼苗茎通气组织的形成和变化。

This paper made a systematic research on Lonicerafulvotomentosa Hsu et S.C. Cheng, which grows well inkarst areas, from its biological characteristics, such asmorphology, growth and physiology. The main conclusions asfollows:(1)From the viewpoint of morphological anatomy, it hastypical xerophyte structures such as well-developed epidermisand tissues that transport water effectively, small leaf area,dense floss under the leaf surface, high stoma density, thesmall opening degree, thick cuticle, well-developed xylem andpalisade tissues, etc. The pollen of L. fulvotomentosa isseems to be spherical, and has 3 grooves, much bulge on theepidermis evenly. The shape of pollen is an important featureon taxonomy. The ripe fruit has from 1 to 18 seeds, some fruitbranch has 135 berry, its diameter is up to 0.8 centimeter.(2)From the viewpoint of growth, L.

本文从形态解剖、生长发育的节律、光合生理特性以及种子萌发生理等生物学特性方面对喀斯特适生经济植物黄褐毛忍冬进行了较为系统的研究，得出以下结论：(1)在形态解剖上，黄褐毛忍冬根茎中含有发育良好的周皮和输导组织，导管密度大，横截面宽，周皮的形成具有节制蒸腾、通气作用和保护组织免受外界环境影响的作用，宽的导管对水分的输导效率高；叶片密被绒毛，面积较小，气孔密度大、开度小，厚的角质层和发育良好的木质部和栅栏组织等是典型的旱生结构；黄褐毛忍冬花粉近球形，具3 孔沟，表面具均匀分布的小刺，刺间具网状纹理。

Three hours OLV does not cause injury of the nondependent lung, yet six hours OLV leads to injury of the nondependent lung. Low-dose ALM would not deteriorate the injury of the nondependent lung.

OLV 3hr不会造成无通气肺组织的损伤，而OLV 6hr则引起无通气肺组织的损伤：小剂量ALM在提高HPV反应，改善OLV期间动脉氧合的同时，并不加重无通气肺组织的损伤。

Malondialdehyde production and total superoxide dismutase activity in samples of nondependent lung and dependent lung were detected and analysed in both groups on time of OLV 3hr and OLV 6hr to determine whether long-term OLV led to injury of the nondependent lung and whether the injury would be deteriorated by low-dose ALM.

通过对OLV 3hr及OLV 6hr时两组实验犬无通气肺与通气肺组织标本中丙二醛含量及总超氧化物歧化酶活力的测定，观察长时间OLV是否引起无通气肺组织损伤，并同时探讨小剂量ALM对无通气肺组织损伤的影响。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
