Longitudinal root sections of the wild type and the gls mutant cultured in nutrient solution for 4 days showed that biosynthesis and distribution of amyloplast in the columella cells of gls were normal as compared with the wild type, suggesting that root gravitropism loss in gls mutant is not caused by the defect in amyloplast sedimentation, but possibly by the disturbance of auxin transport and distributation.

4天龄的根系纵切片结果显示：突变体gls根尖结构完整，根尖柱细胞内淀粉粒的生成和分布正常，表明gls突变体根系向地性的缺失不是由于淀粉体的原因，而可能通过影响生长素运输和分布造成。

In this experiment,garlic root of the material on the garlic apical cell mitosis specimen preparation methods.

The connection with other nucleis of the pallial thickening were studied by retrograde tracer horseradish peroxidase and fluorescent tracer dextran tetramethylrhodamine, Fluoro-ruby.

本研究采用Nissl染色法、golgi -cox法、神经元逆行追踪标记辣根过氧化物和逆行荧光染料葡聚糖四甲基罗丹明方法，分析了蛤蚧皮质加厚区的核团长度、核团体积、细胞大小、细胞形态、细胞密度、初步的亚区分区以及核团的纤维联系，为阐明爬行动物-蛤蚧的视觉通路核团的特征和纤维联系积累形态学和组织学资料。

Laboratory of Gellular and Molecular Biology, Shaaghai Medical College, Fudan University, Shanghai 200032, ChinaAbstract:Objective Using sodium N-lauroyl sarcosine as new decellularization reagent to prepare decellularized matrix for tissue engineering purpose.

吴春根 王松梅高红阳潘銮凤复旦大学上海医学院细胞与分子生物学实验室，200032摘要：目的尝试用十二烷基肌氨酸钠作为脱细胞试剂，制备脱细胞组织工程支架材料，并分析其生物学性能。

However in the preparation of ganglion-body wall, when the mechanical'toucher'was still on the body wall, the high frequence activity of AP eells could make the T and P cells discharge, but no synaptic potential could be found in the T and P cells at the same time. When the contralatcral root was cut, this kind of effects disappeared.

然而，在体壁-神经节标本上，当机械刺激物仍接触表皮时，AP细胞的高频发放使T和P细胞产生动作电位，但此时在T和P细胞上未见有突触后效应，切断神经根这种影响消失。

MTT assay was used to evaluate the cytotoxicity of β-TCP/col on the proliferation of PDLCs. PDLCs were cultured on β-TCP/col and observed by scanning electron microscope.β-TCP/col was implated into muscles of nude mice to observe tissue reactions by histologic methods.Ⅱ° furcation involvements models in beagle dogs were established, scaffold and and scaffold with cells and cytokines were implanted into defects. Histologic observation were conducted.

通过 MTT 法测定β-TCP/col 对犬 PDLCs 增殖的影响，在β-TCP/col 上复合培养犬 PDLCs 并进行电镜观察；将β-TCP/col 植入裸鼠肌袋内并进行组织学观察；建立比格犬Ⅱ°根分叉病变模型，分别植入材料、材料/细胞复合体或材料/细胞/细胞因子复合体，进行组织学观察。

The results showed that the plant had the character of damp-inhabiting, the cutical on the epidermis of stem and leaf is rather thin but without wax-layer, its stomata protrude clearly on the lower surface of leaf, the rate of palisade parenchyma and spongy parenchyma is rather low and the cortex is well developed in root.

结果表明蓝靛果具有明显的湿生特征：茎、叶表皮的角质层薄，无蜡被；叶片上表皮细胞甚大，无气孔，下表皮细胞小，气孔明显突起；叶脉导管直径小，壁薄；叶肉栅栏组织/海绵组织小；根的皮层发达，富细胞间隙。

The Plant tissue raise is the plant sterile culture technology, has the totipotency theory according to the vegetable cell, the use plant body exsomatize organ (for example root, stem, leaf, stem point, flower, fruit and so on), the organization (for example cambium, epidermis, cerebral cortex, marrow department cell, endosperm and so on) or the cell (for example big spore, small spore, somatic cell and so on) as well as the protoplast, in aseptic and suitable artificial culture medium and illumination, temperature and so on under artificial condition, can induce injuries the organization, not to decide the bud, the adventitious root, finally forms the complete adult plant the discipline.

植物组织培养即植物无菌培养技术，是根据植物细胞具有全能性的理论，利用植物体离体的器官(如根、茎、叶、茎尖、花、果实等)、组织（如形成层、表皮、皮层、髓部细胞、胚乳等）或细胞（如大孢子、小孢子、体细胞等）以及原生质体，在无菌和适宜的人工培养基及光照、温度等人工条件下，能诱导出愈伤组织、不定芽、不定根，最后形成完整的植株的学科。

In the process of hair follicle regeneration, GFP+ cells located in outer root sheath cells of the hair follicle could different to epidermal cell around hair follicle.

此外，本实验观察到，在毛囊再生过程中，位于新生毛囊外根鞘细胞的荧光细胞可向毛囊周边表皮细胞迁移分化和增殖。

During catagen of hair follicles, TGF-β2 protein could be found in outer root sheath cells, follicle bulge cells and fibroblasts of connective tissue sheath.

在毛囊的退行期，毛囊外根鞘细胞、毛隆突细胞和结缔组织鞘成纤维细胞中有阳性表达。

Fancy gold-plated dangling earrings with facetted White Opal crystals.

花式镀金悬垂耳环与facetted白欧泊水晶。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
