Part I: Characterization of the stability and biocompatibility of PLGA conduits.1 Artificial nerve conduits were successfully fabricated using two different copolymer ratios of PLGA(85:15 and 50:50)(lactide:glycolide).2 Degradation of PLGA(85:15) and PLGA(50:50) conduits were examined in vitro for 12 weeks in phosphate buffered saline at 37℃, pH 7.4 and in vivo for up to 8 weeks following implantation into the rat dorsal muscle.

结果显示：①体内外降解条件下，PLGA(50：50)管吸水率、失重率及生物降解率显著高于PLGA(85：15)管；②两种材料样品体内生物降解率显著高于体外降解率；③扫描电镜观察显示，随降解时间延长，材料样品表现为特征性的虫蚀样破坏并进行性加重，以PLGA（50：50）管尤为明显。

More detailed in vivo and in vitro herbicidal activity was determined for 01806, 01808. The results showed that they have excellent herbicidal activity, and they could find use in soybean and wheat field.

对初期发现的两个有一定苗头的化合物01806和01808进行详细的体外和体内除草活性测试，大幅改进了合成方法，发现二者都是超高效除草剂，首次提出其适用作物及用量，并已申请专利。

The heterogenic C57BL/6J splenocytes disappeared at 1 day after transfusion, but the syngeneic BALB/c splenocytes could survive for a long time in the peripheral blood of BALB/c mice. The fluorescence intensity was not decreased in two kinds of splenocytes. The results demonstrated that CFSE-labeling with difference concentration is reliable, stable and convenient for spleen lymphocytes tracing in vivo.

异基因的C57BL/6J脾细胞在输注1 d后就快速消失，而同基因BALB/c脾细胞能够在BALB/c小鼠外周血中长期存在，但是两种细胞荧光强度均未见降低，说明荧光染料CFSE差异浓度标记活细胞进行体内示踪是一种稳定的示踪方法。

Objective To observe the development of mouse kidney in vitro at embryonic day 12、14、16 and postnatal day 1, and compare with the development of homeochronous kidney in vivo. And to select eligible the embryonic age for kidney culture in vitro.

目的 观察胚龄12、14、16、以及生后1天的肾组织体外培养的发育情况，与同期在体发育进行比较，探讨肾组织体外培养的胚龄选择。

These results suggest that the Rho-kinase-mediated pathway plays a crucial role in the ROS production through NADPH oxidase in hepatocytes during the hyperacute phase of reperfusion in vivo.

这些结果表明，在体内再灌注的超急性期，Rho-激酶介导途径通过肝细胞NADPH氧化酶，在ROS生成中发挥着决定性的作用。

The H2S donor probably has a direct effect on the intramyocardial and cardiac fibroblast in vivo in addition to its effect in blood pressure reduction.

此外，本实验首次发现了H2S可能具有降糖作用，这也将为防治糖尿病新药的开发提供一个新的研究方向。

The purpose in the second part of the paper is investigating hANF gene expressions in rabbit myocardial tissue by intramyocardial injection of naked pCR3. hANF in vivo.

本课题第二部分在前期研究的基础上，将pCR3.hANF进行在体转染研究，通过心室肌内直接注射裸pCR3.hANF，观察兔心肌中hANF基因的表达。

We introduced improved primary mixed glial culture and different-attachment method to isolate and purify the OPCs, the cells were proliferated in serum-free medium, flow cytometry and immunohischemistry methods were employed to estimate the purity of cultured OPCs. Their abilities of differentiation and expression of trophic factors were identified by RT-PCR and immunostaining. Several methods including TUNEL and MTT were adopted to estimate the protective effects of conditioned culture medium from oligodendrocyte lineage cells on the primary cultured cerebellar granule neurons. Intravitreal transplant of OPCs, combined with retrograde fluorescent labeling the superior colliculus and intraorbital optic nerve transection, were used to investigate the protective effects of OPCs on the axotomized RGCs in vivo. Intravitreal transplantof OPCs or NSCs on the newborn rats, and retinal transplant of OPCs on the young rats were performed, to observe the myelin formation in the retina at different stages after cellular transplantation. Optic nerve transection was carried out on some rats with myelinated retinae, to study the influence of myelination on the injuried RGCs.

为此，本研究采用改良的胶质细胞混合培养与差速贴壁方法获得大鼠OPCs，使用无血清培养基进行扩增、培养，用免疫组织化学和流式细胞技术对培养细胞的纯度进行鉴定，对少突胶质系细胞表达部分营养因子的情况进行检测；采用TUNEL、MTT等方法对少突胶质系细胞条件培养基对原代培养小脑颗粒神经元的保护作用进行检测；将OPCs移植入成年SD大鼠玻璃体内，利用上丘逆行荧光标记技术，观察眼内移植的OPCs对眶内视神经切断时的视网膜神经节细胞的保护作用及其持续时间；将OPCs或NSCs移植入新生和幼年SD大鼠玻璃体或视网膜内，观察不同时期视网膜内髓鞘形成与分布特点，分析髓鞘的超微结构，并观察眼内髓鞘形成对损伤神经节细胞的保护作用。

To check the abilities of Zn uptake and accumulation of duckweed (Lemna minor Linn.), experiments of growth, Zn accumulation and SOD activitial response to Zn in plant duckweed were performed with fresh plant in vivo.
