| | Purpose:To investigate the effect of N-methyl-D-aspartate(NMDA) and Dexametha-sone on cultured rat retinal ganglion cells (RGCS). | | 目的:研究N-甲基-D-天门冬氨酸(N-methyl-D-aspartate NMDA)及地塞米松对体外培养视网膜神经节细胞(RGCs)的作用。方法:出生1~3天Sprague-Dawley(SD)乳鼠做体外RGCs培养。NMDA按20~500μmol/L加入两组混合培养的RGCs中,24小时后一组用Hochest33258检测凋亡细胞。另一组加0.4%台盼蓝,计数拒染细胞,并算出细胞存活率。地塞米松按1×10~(-4)、1×10~(-5)及1×10~(-6)mol/L分别加入混合培养及纯化培养的RGCs中,对照组不加,24小时后用Hochest33258检测凋亡细胞。结果:混合培养RGCs经不同浓度NMDA处理均可见明显的凋亡细胞形态学改变。对照组则不明显。而且其中细胞的存活率与NMDA浓度呈反相关。不同浓度地塞米松处理混合培养RGCs,经Hochest33258检测均未发现有凋亡形态学改变。而纯化培养RGCs实验组及对照组均有明显凋亡细胞形态学改变。结论:NMDA... | | 文摘来源 | | Objective To investigate the effects of N methyl D aspartate (NMDA), MK801 (non competitive blocking agent of NMDA receptor) and Ca 2+ on cultured retinal neurons and the interaction of these reagents. Methods NMDA, MK801 and Ca 2+ were singly and jointly added to the retinal neurons after primary culture for 7 days which obtained from 1 3 day old postnatal Sprague Dawley rat. The cells were identified wi... | | 目的 探讨N 甲基 D 天冬氨酸 (N methyl D aspartate,NMDA)及其非竞争性受体阻滞剂(MK80 1)和Ca2 + 对培养的鼠视网膜神经细胞的作用及其相互间的关系。方法 取生后 1~ 3d鼠龄的Sprague Dawley(SD)乳鼠视网膜作为原代视网膜神经细胞进行体外培养 ,对培养 7d的视网膜神经细胞经抗神经丝蛋白 (neurofilamentprotein ,NF)、Thy1 1及抗胶质纤维酸性蛋白 (glialfibrillaryacidicprotein ,GFAP)单克隆抗体进行鉴定 ,同时在培养 7d的神经细胞中单独及联合加入NMDA、MK80 1和Ca2 + ,锥虫蓝拒染 ,计算细胞活性。结果 2 0 0 μmol/L的NMDA及 10mmol/L的Ca2 + 所致视网膜神经细胞失活与对照组比较 ,差异有显著意义 (F =2 6 0 91;P =0 0 2 5 ,P <0 0 0 1... | | 文摘来源 | | Objective To investigate the expression and distribution of N methyl D aspartate receptor subunit 1 (NMDA R1) in neuronal ultrastructure in visual cortex of strabismic amblyopic cat during development. Methods Eleven kittens were used for this study. Esotropia in six kittens had been made monocularly by tenotomy at two weeks of age. Two pairs of normal and strabismic kittens were sacrificed in three weeks of age, one week after tenotomy. An... | | 目的 研究不同发育阶段斜视猫视皮层神经元N 甲基 D 天门冬氨酸受体亚基 1(N methyl D aspartatereceptorsubunit 1,NMDA R1)在超微结构水平的表达与变化。方法 幼猫 11只 ,其中 6只猫在 2周龄行 1只眼外直肌断腱术产生单眼内斜。依动物处死时的年龄分为 3组 :3周龄组(斜视手术后 1周 ) ,2只正常和 2只斜视幼猫 ;5周龄组 (斜视手术后 3周 ) ,2只正常和 2只斜视幼猫 ;成年组 (6月龄 ) ,1只正常和 2只斜视性弱视猫。 3组动物均取初级视皮层组织进行冰冻切片 ,NMDA R1单克隆抗体标记后 ,分Ⅱ~Ⅲ层、Ⅳ层及Ⅴ~Ⅵ层各为一个区块行常规电镜染色切片 ,透射电镜观察。结果 (1)电镜下分析 32 8个视皮层神经元 ,发现 3组正常猫的视皮层神经元NMDA R1标记阳性细胞数均高于斜视猫 (χ2 =4 2 8,4 4 1,4 89;P <0 0 5 )。 (2 )共计数 132 0个NMDA R1阳性突触 ,显示正常... | | 文摘来源 | |   | | << 更多相关文摘 |
