At 8 weeks postoperatively, the grafts were mostly substituted by new cells, and the artificial ligament was completely parceled by the synovial membrane, but there were still some gaps; The combined tendon exhibited no loose or disfiguration, the infiltrative inflammatory cells disappeared. The cells in grafts were close to normal cells in anterior cruciate ligament, but fibrocytes arranged in disorder and fibers showed a verticality.

移植后第8周，移植物大部分组织被新长入的细胞替代，人工韧带被滑膜完全包裹，浸润的炎症细胞基本消失，部分接触面已融合，但部分面仍有间隙；联合肌腱无变形和松弛，移植物内细胞形态，数量接近正常前交叉韧带，但纤维细胞排列杂乱，纤维有了一定的纵向性。

Its main features are: algae body as a single cell or even into a variety of groups; cell walls composed of silica and pectin, but also by the structure of the shell and the shell under the combined set of the Cheng, vertical section view was "soap-box"-shaped; in the upper and lower shell surface of the shell are patterns arranged in patterns on both sides of the main mode of symmetry and radial symmetry is divided into two categories, for the classification of the most important basis; be able to campaign Type in the shell has a shell side seam, can not be changed no shell seam types; pigment body sheet or ribbon, 1 or 2, or for multiple small discoid, yellow green or brown, containing chlorophyll a, c, also contains fucoxanthin and silicon A flavin and other photosynthetic pigments; storage material mainly for oil droplets; reproduction mainly for cell division and cell division in diatoms obvious features are: each cell division, resulting from two sub-cells,, only one and the mother cell and so big, the other one is smaller.

其主要特征是：藻体为单细胞或连成各式群体；细胞壁由硅质和果胶质组成，而且在结构上都是由上壳和下壳套合而成，纵断面观呈"肥皂盒"形；在上下壳的壳面上有花纹，花纹排列的方式主要分为两侧对称和辐射对称两大类，为分类上的最重要依据；能运动的种类在壳面都有壳缝，不能动的种类均无壳缝；色素体片状或带状，1个或2个，或为多个小盘状，黄绿色或黄褐色，含叶绿素a、c，还含有墨角藻黄素和硅甲黄素等光合色素；贮藏物质主要为油滴；繁殖方式主要为细胞分裂，硅藻的细胞分裂的明显特点是：每次细胞分裂所产生的2个子细胞中，仅有1个和母细胞等大，另1个则稍小。

Further studies are underway to investigate the exact intracellular mechanisms underlying the effects of the two substances. In Chapter 4, we observed the effects of metabolites of mangrove fungus Xylaria sp. from the South China Sea Coast, Xyloketal A～D, on the activity of acetylcholinesterase in vitro, and the present data indicated that AChE activity was remarkably inhibited by Xyloketal A～D in a dose-dependent manner.

另一方面，在论文第3章离体豚鼠回肠收缩实验中，发现323-A和323-B可剂量依赖性地抑制组胺、乙酰胆碱以及氯化钾所引起的GPI收缩，pD2'依次为5.13、4.97、5.36和5.51、5.56、5.62，并且，通过机制分析发现，323-A和323-B可以显著降低在外界无钙离子存在时由细胞内钙储库释放钙所产生的收缩反应，而对由细胞外钙离子内流所引起的收缩无明显影响。

Results: in contrast with model group, SSM can (1) increase the survival rate of ARF in rats, cut down Scr and BUN at 24hr, improve renal function, slightly surpass Vp in its therapeutic effect;(2) mitigate the extent of renal pathologicchanges, decrease the numbers of renal tubule necroses and casts;(3) protect renal ultrastructure such as microvilli, mitochondria, endoplasmic reticulum of TEC, podocytic process of glomerulus epithelial cell,endothelial cell etc, better than Vp;(4) enhance SOD activity, lower MDA contents in renal cortex;(5) enhance NO contents in serum, reduce ET levels in plasma;(6) evidently cut down TNF- a contents in serum, superior to Vp;(7) antagonize calcium overload in TEC;(8) alleviate renal pathological changes in ARF metaphase (at 3d), advance regeneration and recovery of TEC, restore renal structure in ARF convalescence (at 5d), and better than Vp;(9) increase the expression of TEC PCNA and prepro EGFmRNA in ARF metaphase.

结果：与模型组相比，SSM能(1)提高ARF大鼠的存活率，降低24hr时Scr及BUN，改善肾功能，其疗效略优于维拉帕米；(2)减轻ARF肾脏病变程度，减少24hr肾小管坏死数及管腔内管型数；(3)对肾脏的超微结构如肾小管上皮细胞微绒毛、线粒体、内质网、肾小球上皮细胞足突、内皮细胞等形态结构均有一定的保护作用，其疗效略优于维拉帕米；(4)提高肾皮质SOD活性，降低MDA含量；(5)提高血清NO水平，同时降低血浆ET含量；(6)显著降低血清TNF-α的水平，疗效明显优于维拉帕米；(7)拮抗小管上皮细胞[Ca~(2+)]_i的升高；(8)使ARF中期(第3d时)肾组织病变较同期其它两组明显减轻，并使肾小管细胞再生修复提前，至ARF恢复期(第5d时)肾组织结构恢复重建良好；作用明显优于维拉帕米；(9)促进ARF中期肾小管上皮细胞PCNA的表达及EGF前体mRNA的合成，从而增加EGF的合成释放，而维拉帕米无此作用。

METHODS: Umbilical cord blood samples were sterilely isolated using Percoll density gradient centrifugation to harvest intermediate layer cells. DMEM medium containing fetal bovine serum, penicillin, streptomycin and L-glutamine was added. Following several adherences and purification, the floating cells were discarded. Thus, many adherent cells with a confluence were collected. When cells were 60%-80% confluent, cells were digested by trypsin for subculture.

Methods After Candida albicans were inoculated into the specific pathogen free mice, the total amount of Candidas in cecum and the amount of which attached to the mucosal membrane were counted at different interent intervals. The lymphocyte proliferation in Peyer's patch and in lamina proper was shown by BrdU incorporation, meanwhile B cells isotype switch in PP was investigated. IgA plasma cells were shown by immunohistochemical staining. Specific IgA antibodies to Candida albicans were measured with ELISA.

Histologically, the seminiferous tubules contained numerous Sertoli cells and more Sertoli-spermatozoa complexes, accompanied by the depletion of Leydig cells with deeply stained nuclei. Mature spermatozoa were stored up in the epididymis, but only a few in the efferent ducts. In the second place was testicular atrophy（32/120; 26.7%）. The seminiferous tubules showed moderate to severe inactivity of spermiogenesis with evidence of only spermatogonia, spermatocytes and Sertoli cells. The Leydig cells were obviously decreased in numbers associated with decrease of lipid droplets in their cytoplasms. Testicular hypoplasia was the third disorders（22/120; 18.3%）. Only a few spermatogonia and Sertoli cells appeared without any spermiogenesis. The associated changes was decreased in Leydig cells and fibrous hyperplasia in the interstitium.Epididymal stones were sometimes found（12/120; 10%）. Grossly, yellowish-white nodules with various sizes and firm in consistency were observed in the epididymis and the front efferent ducts. Microscopically, the epididymal ducts were dilated with voluminous spermatozoa storage, even showed calcification in severe cases. The deposited calcium salts were stained positively by Von Kossa and Alizarin red methods.Amyloidosis was also detected in 10 roosters（8.3%）. Eosinophilic, homogeneous, amyloid-like substances were deposited mainly in the testicular interstitium and the periphery of blood vessels. These substances showed positive reaction by Congo red staining. Five roosters（4.2%）had Marek's lesions in the testis, epididymis and peripheral nerves with infiltration of pleomorphic lymphocytes. Only one case showed epithelial necrosis of seminiferous tubules accompanied by fibrous proliferation in the interstitium.

结果发现，在总共搜集的120个病例中，其中因年老所导致的产精力不佳为最多，占38例（31.7%），於镜下可见大量精虫黏附於Sertoli cell的表面，并可见Sertoli cell数量明显增多而Leydig cell明显减少，且其细胞核呈现浓染的现象，而在其副睪中仍可见到成熟精虫蓄留於管腔中，但在其输精管内却只有少量精虫存在；其次为睪丸萎缩，占32例（26.7%），镜下可见中度至重度无造精作用，其生精小管中只见到精母细胞、精原细胞及Sertoli cell存在，但Leydig cell数量明显减少且其细胞质内的脂质也明显减少；睪丸发育不全，占22例（18.3%），於生精小管内只见到精母细胞及少量Sertoli cell存在，不见造精细胞分化，於生精小管间质可见Leydig cell减少并伴随结缔组织增生；副睪结石，占12例（10%），肉眼下可在副睪及输精管前段见到黄白色大小不一的结节，触感坚硬，於镜下可见副睪管扩张并有大量成熟精虫蓄积，严重时可见钙化现象，以Von Kossa及茜素红染色均呈阳性反应；类淀粉沉著症，占10例（8.3%），镜下在睪丸间质及血管周围可见粉红均质样的物质沉积，以刚果红染色成阳性反应；马立克病，占5例（4.2%），镜下可在睪丸、副睪实质及周边神经内均可见到嗜碱性大小不一的淋巴样细胞浸润；睪丸坏死，占1例（0.8%），镜下可见生精小管上皮细胞坏死脱落及间质结缔组织增生。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.
