Dose-dependent toxic effects in primary cultured astroglia could be induced by exposed to iAsⅢ or iAsⅤ within the concentrations of 25～100 μmol/L or 100～500 μmol/L, respectively.

接触最少25 μmol/L的3价无机砷或100 μmol/L的5价无机砷对星型胶质细胞可产生明显的毒性损伤作用。3价无机砷的毒性明显大于5价无机砷。

The plasmid DNA bands were detected clearly by agarose-EtBr gel electrophore sis.Two forms of plasmid DNA molecules,namely covalently closed circular DNA mol e-cules and open circular DNA molecules,were observed under electron microscope.

用琼脂糖-溴化乙锭凝胶电泳分析在两株菌的DNA中鉴别出明显的质粒带，用电镜方法在两株菌的DNA制剂中均观察到共价闭合超螺旋和开放型环状两种构型的DNA分子。

Mutant mice than in wild-type controls, and tetrodotoxin or bicuculline application abolished the difference between the genotypes. Studies on human oligodendroglioma cells revealed that GABA played a protective role on Ca〓 overload induced by OGD or glutamate and phaclofen, GABA〓 receptor antagonist, could significantly block the protection.

结果表明：①电凝大脑中动脉后Ca〓2.3-／-鼠脑梗死率和缺血后运动障碍明显重于Ca〓2.3+／+鼠；②Ca〓2.3-／-鼠海马脑片CA1区缺氧后钙超载明显高于Ca〓2.3+／+鼠；③Na〓通道阻滞剂TTX和GABA〓受体阻断剂bicuculline可显著缩小遗传表型之间的差异；④GABA对缺氧无糖及谷氨酸所致的人胶质细胞瘤细胞Ca〓超载有明显的保护作用，此作用可被GABA〓受体阻断剂phaclofen拮抗。

To elucidate the molecular mechanisms underlying the neural plasticity after CNS injury, the gene expression profile in the rat hippocampus following perforant path transections was explored by several methods including custom differential screening, custom cDNA array and cDNA microarray. Of 2300 cDNA clones from low-abundance rat brain cDNA bank, 6 were identified as differentially expressed genes/ESTs in the hippocampus 35 days after lesion, in which none was confirmed by Northern blot. Of 8000 cDNA elements, custom cDNA array identified 47 as differentially expressed genes/ESTs with above 3-fold changes in the hippocampus 35 days after lesion, in which 25 were up-regulated and 22 down-regulated.

The bone mineral density of the subchondral cancellous bone as well as levels of urinary N-telopeptide of type I collagen and serum osteocalcin were measured.

我们检测了软骨下松质骨的骨矿物质密度以及尿Ⅰ型胶原N末端肽和血清骨钙素的水平。

The bioactivity of bFGF released from PLGA microspheres are higher than from PELA.(2) the bFGF released from PLGA microspheres can stimulate mitosis, proliferation, and matrix synthesis of chondrocyte more effectively than free bFGF. 10 days later after the administration of PLGA microspheres, the effects of stimulus to synthesis of type Ⅱ collagen and proteoglycan can be compared with continue administration of free bFGF.

游离bFGF对软骨细胞的促有丝分裂的作用效应期短；bFGF缓释微球能通过持续释放活性bFGF，在较长时期内促进软骨细胞的分裂增殖；Ⅱ型胶原免疫荧光测定和蛋白多糖阿新兰染色测定显示，应用微球10天后，能有效的促进软骨基质成分的合成，其效果与持续应用游离bFGF的效果相当。

A new method and device were first introduced to measure the deformation rate and deformation degree of silastic membrance in the stretch induced cultured cell injury process.

对培养的新生大鼠大脑皮层星型胶质细胞应用本致伤装置采用不同的条件致伤，检测乳酸脱清酶活性和台盼蓝含量，并观察其形态学的改变。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
