Methods This study consisted of 36 male Wistar rats. A rat model of intestinal adhesions was done as follows: serous membrane of the caecum was scuffed, its raw surface was dropped with absolute alcohol, the mesentric artery of the caecum was then clamped. The rats were divided into three groups. PSS, sodium hyaluronate or normal saline was applied to the scraped cecum before closing the abdomen.

It has been proved that it was an amorphous plastics with high glass temperature,soluble in some solvents at room temperature and the polymer was also an intermediate product of cross-linked copolymer and grafted copolymer.

结果表明，这系列聚合物是具有较高的玻璃化温度的可溶性无规共聚物。聚合物含有不饱和双键结构，可作为交联聚合物、接枝聚合物及其它特种高分子材料的中间体。

Calcium carbonate and soluble glass and so on were confected as alkaline antifouling agent. The Infrared Spectrometry results showed that 2275-2250 cm~(-1) diagnostic absorb wave crest in part A and 3390-3200 cm~(-1) in part B and 1730 cm~(-1) in coating film strongly proved polymers reacted just as the reacting mechanism, that means polysiloxane which offer low-surface-energy property linked Polyurethane system by —OH groups reacting with —NCO groups. Relative molar mass of part A and part B was determined by Gel Permeation Chromatography and the results were appropriate. Surface-energy was determined and results were between 33.6-47.17 mN/m and it increased when alkaline antifouling agent was put into the coating. Alkaline antifouling agent was releasing steadily when the coating film was dipped in seawater. As time gone, the pH value of seawater was increasing. Solubility parameter and results showed that there was no corrasive phenomenon between the polyethylene strand and the coating.

红外光谱分析结果表明，出现在A组分中的2275～2250cm~(-1)处的异氰酸酯特征吸收峰、B组分中的3390～3200cm~(-1)处硅羟基的特征吸收峰及出现在固化后涂膜中的1730cm~(-1)处氨基甲酸酯基团的特征吸收峰证明了涂料成膜物质交联固化符合本文的设计要求，即赋予涂膜低表面能特性的有机硅组分通过—OH基团与—NCO基团的反应已经链接到聚氨酯体系中；凝胶渗透色谱结果表明，成膜物质的A、B组分均为低分子量，符合预聚物的要求；涂膜表面能的测算结果表明，涂膜的表面能在33.6～47.17mN／m之间；加入碱式防污剂后涂膜的表面能略有升高；碱式防污剂的释放平稳，随着涂膜在海水中浸泡时间的增长，pH值有增加的趋势；用溶解度参数原则来评价涂料与网绳的涂装，结果表明，本试验研制的防污涂料对聚乙烯网绳无溶蚀作用。

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。

The product was characterized by means of X-ray diffraction, transmission electron microscope and Fourier transform infrared spectroscope.

采用硅烷和氨气在立式双温区流态床中化学气相沉积，制备了形状规则的球状无定形氮化硅纳米粉体，并利用X射线衍射、透射电镜和傅立叶红外研究了该纳米粉体的形貌、成分和物相。

The spermatozoa are embeded in a extracellalar matrix composed of high dense fibrils matrix and flocculent and concentric vesicles similar to that in the primary spermatophore layer, but the later lack of spermotozoa. The flocculent and concentric vesicles are often seen to release their contents around the main body of spermatozoa. The spermatozoa may absorb the contents to form vesicular zone and membrane zone in sperm nucleu. The secondary spermatophore layer is distinctly subdivided into inner region and outer region. The loose outer region consists of canaliculated reticulum and large flocculent vesicles.

输精管内的精荚为管状，由精子群、精荚基质及初级精荚壁和次级精荚壁组成，初级精荚壁与精荚基质是相连续的，它们之间无明显界限，两者均由电子密度较高的纤丝状基质和絮状泡和同心圆泡组成，但后者不含精子，后者中的絮状泡和同心圆泡常在精子主体部周围释放内含物，可能与形成精子细胞核中的泡状带和膜状带有关，在交配后的雌虾，其头胸部腹面上粘着的精荚中，其基质内已不见絮状和同心圆泡，仅见稀疏的纤丝。
