The results showed that in undifferentiated P19 cells, Tra2β1 increased the Flop splicing of GluR-B and BEK splicing of FGF-2R. At the neuronal dominant stage of differentiated P19 (at 9d after RA induction), Tra2β1 increased the Flop splicing of GluR-B, but had no obvious effects on the splicing of FGF-2R. At the glial dominant stage (at 13d after RA induction), Tra2β1 increased the Flop splicing of GluR-B, but had obvious inhibitory effects on the splicing of FGF-2R.

结果表明，在未分化的P19细胞中，Tra2β1能增强GluR-B的Flop剪辑和FGF-2R的BEK剪辑；在P19分化至神经元为主的阶段（RA诱导后第9天），Tra2β1明显增强GluR-B的Flop剪辑，而对FGF-2R的BEK剪辑无明显影响。P19分化至胶质细胞为主的阶段（RA诱导后第13天），Tra2β1明显增强GluR-B的Flop剪辑，但对FGF-2R的剪辑有明显抑制。

The species of extracellular ATP can participate the effect of nerve system not only as the neurotransmitter and modulator but also has a trophic action to glial cell and neuron. It participates in many courses, e.g. cell differentiation and apoptosis, the morphologic change of chondriosome, to stimulate the synthesis and release of cytokine and nerve growth factor. It has a great influence to neurological growth and plasticity.

细胞外ATP类物质不仅可以作为神经递质及调质参与神经系统的功能，还可对胶质细胞及神经元产生营养作用，广泛参与细胞分化及凋亡、细胞线粒体形态变化、刺激细胞因子及神经生长因子的合成及释放等过程，对神经系统的发育及可塑性变化产生重要的影响。

Methods A recombinant antisense GFAP retrovirus was developed. After packing and concentrating, the suspension of this retrovirus was injected into the sites of injured brain stab by a microinjector. The effect of recombinant antisense GFAP retrovirus on formation of glial cicatrix in the injured sites was studied through immunohischemistry and morphological observation.

构建反义GFAP逆转录病毒表达载体，经过病毒包装后，将获得的病毒上清液浓缩并通过微量注射的方法，引入大鼠脑穿刺损伤灶内，采用免疫组化及形态学观察的方法，研究重组反义GFAP逆转录病毒对脑损伤后胶质瘢痕形成的影响。

Results The recombinant retrovirus resulted in the number reduction of GFAP positive cells around the injured sites. The typical characteristics of reactive gliosis disappeared. The formation of the glial cicatrix was inhibited.

结果 重组反义GFAP逆转录病毒使脑穿刺损伤灶周围GFAP阳性细胞数量明显减少，反应性胶质化的典型特征消失，胶质瘢痕形成明显减少。

The main component of ramie glial was pectin, hemicellulose and lignin; The single factor on degumming of ramie test was respectively analyzed with a high vigorous of pectinase KDN and TZ-888 compound enzyme （mainly xylanase and mannanase on the pH value, bath ratio, dosage of enzyme, metal ions, temperature and time.The orthogonal test of L9（34 were done by bath ratio, dosage of enzyme, temperature and time. The results showed that the best compages of KDN pectinase on degumming was 1∶12 of bath ratio,pH 8.6,1 mmol/L Mg2+,300 IU/g of KDN pectinase,35℃、6 h;the best compages of TZ-888 compound enzyme on degumming was 1∶18 of bath ratio,pH 4.0,1 mmol/L Ca2+, 500 IU/g of TZ-888 compound enzyme,45 ℃,6 h.

摘 要：本研究根据苎麻胶质的主要成分为果胶、半纤维素和木质素，用高活性的KDN果胶酶和TZ-888复合酶（主要是木聚糖酶和甘露聚糖酶）从pH值、浴比、酶用量、金属离子、温度、脱胶时间等方面进行单因素试验，然后选取影响显著的浴比、酶用量、温度，时间进行四因素三水平的脱胶试验，结果表明鲜麻采用KDN果胶酶脱胶最佳组合为浴比1：18，pH 8.6， 1 mmoL/L Mg2+，酶用量300 IU/g，温度35 ℃、时间6 h时处理，TZ-888复合酶脱胶最佳组为浴比1：12，pH 4.0， 1 mmoL/L Ca2+，酶用量500 IU/g，温度45 ℃，时间6 h进行脱胶为优化的试验条件。
