The protoxylem vessels initiated lignification in the early stage of vascular bundle differentiation, whereas metaxylem vessels and fiber walls started lignification from the middle lamella and cell comers after completion of vascular bundle differentiation. The walls of most parenchyma cells lignified after the stem reached its full height, while a few parenchyma cells remained non-lignified even the culm is 7 years old.

研究结果表明：毛竹茎的原生木质部导管在维管束发育早期就已木质化；后生木质部导管和纤维细胞在维管束分化完成后，自胞间层和细胞角隅处开始木质化；基本薄壁组织细胞木质化的发生较晚，通常在茎的节间完成伸长生长后才开始，但也有少数薄壁组织细胞始终保持非木质化的薄壁状态。

The numbers of labeled neurons in the left were more than those in the right,and that in the spinal were more than those in the jugular and nodose ganglia.

标记细胞数分布不均，在体左侧多于体右侧，在脊神经节多于颈静脉神经节和结状神经节。

After treatment of CCl4 through oral route for four weeks, we have observed an interesting phenomenon in the animal model. That is the significantly decreased condition of nitric oxide synthase. The locations are sympathetic T7-T10 dorsal root ganglion, T7-T10 intermediolateral cell column, celiac ganglion, parasympathetic nodose ganglion, solitary tract nucleus, and dorsal motor vagal nucleus.

结果显示：在餵食四氯化碳四周起，其交感神经回路上的T7-T10背根神经节、T7-T10脊髓侧角中间外侧细胞柱之交感节前神经元以及位於腹腔神经节的交感节后神经元所含之一氧化氮合成下降；而副交感神经回路上的小结神经节、孤立径核以及迷走神经背侧运动核所含之一氧化氮合成亦下降。

ESEM showed on one highly mineralized construct that partial displacement of oneosteoclast exposed specialized structures of the cellular membrane facing the bonesurface, namely, the ruffled border and podosomes of the sealing zone, as well as theresorption pit under the ruffled border, unequivocally indicating that osteoclast-likecells formed have the ability to resorb bone-like matrix produced by osteoblasts invitro.

细胞在大矿化结节周围分布的差异反映了在大小类似的情况下，结节矿化程度越高，对周围的TRAP阳性细胞的趋化能力越强。F-actin荧光染色显示了在大矿化节结上F-actin环的出现，这是破骨细胞具有吸收活性的特征标志，直接证明了所形成的类破骨细胞具有骨吸收活性。

PPARγ expression in PAN-treated rats at 12 weeks was present in podocytes and in mesangial cells in segmentally sclerotic glomeruli, with occasional parietal epithelial cell staining.

给予PAN后，PPARγ可以在节段硬化小球的足细胞和系膜细胞上表达，部分在壁层上皮细胞表达。6周后给予吡咯列酮治疗，可以减少系膜区的PPARγ染色，但足细胞上的染色明显增强，伴有小球硬化明显减轻。

MethodsNeural tubes isolated from the region between midotic placode and third somite of mouse embryo at ED 8.5d were cultured in DMEM/F12 serum-free medium containing basic fibroblast growth factor and epidermal growth factor. The cell cycle of CNCCs was analyzed with flow cytometry, the proliferation capability was determined by MTT method, AP-2α expression was detected by immunocytochemistry as a biological marker of cardiac neural crest cells. The features of migration, multi-directional differentiation were observed as well.

材料与方法成年2月龄C57／BL6小鼠交配，取ED8.5d小鼠胚胎枕中部至第3体节神经管，应用包含碱性纤维生长因子和表皮细胞生长因子的无血清培养基培养，利用MTT法检测细胞增殖能力，利用流式细胞仪检测细胞周期，采用转录激活因子2α(AP-2α，Activator protein-2α)作为其生物学标记物，观察其增殖状况、细胞周期、迁移、分化等生物学特性。

And the leaf succulence of Salsola implicata and Suaeda linifolia changes drastically, strong drought resistance is indicated, but that of Halocnemum strobilaceum and Kalidium foliatum is not

后期：亚麻叶碱蓬和密枝猪毛菜叶表面腺毛、密枝猪毛菜盐腺、盐节木乳突状突起明显；密枝猪毛菜盐囊泡有或缺；密枝猪毛菜和亚麻叶碱蓬粘液细胞出现；盐节木和盐爪爪贮水组织和异常维管束发达；除盐节木外，其他三种植物叶肉质化加强；这四种植物气孔下陷，栅栏组织变薄，但排列更紧密。

In Wistar rats, latent period of a-wave in scotopic rod response after 1-week transplantation was shorten (P.05); and latent period of a-wave in scotopic rod response after 2-week transplantation was prolonged (P.05); while latent period of b-wave in scotopic maximum response after 1-week transplantation was shorten (P.05). In RCS rats, amplitude of a-wave in scotopic rod response and photopic response after 4-week transplantation was increased (PO.05); while latent period of a-wave in scotopic rod response after 4-week transplantation was shorten (PO.05).Conclusion 1. At the age of 3 months, photoreceptors of the RCS rat degenerated completely, which leaded to the reduction of amplitudes of a-wave and b-wave.

Meanwhile,many researches have indicated that ischemia,oxygen deficiengcy and excessive sound stimulus all induce inner hair cell and supporting cell to release excess glutamate which poison the hair cell, afferent neurofibers,ganglion spirale.

同时，许多研究表明，耳蜗缺血、缺氧或过度声刺激均可使耳蜗内毛细胞、支持细胞释放大量Glu，对耳蜗内毛细胞、外毛细胞、传入神经纤维和螺旋神经节产生毒害作用。

Positive nerve fibers are in pedal nerve cords and visceral nerve cords. There are no neuronal nitric oxide synthase or inducible nitric oxide synthase positive cells or fibers in the nervous system. A few of endothelial nitric oxide synthase strongly positive nerve cells are identified in pedal ganglia and visceral ganglia. Weakly positive cells and nerve fibers of eNOS can be seen in all of the ganglia and nerve cords.

免疫组化定位表明，神经型一氧化氮合酶和诱导型一氧化氮合酶在整个神经系统内均呈阴性；足神经节和脏神经节内有少量神经细胞呈内皮型一氧化氮合酶强阳性；各神经节和神经索内的部分小细胞和神经纤维呈eNOS弱阳性。
