1.Methods Fifteen eyes of 14 patients with macular holes underwent scanning of their affected macular area using the Heidelberg retina tomograph (HRT). The significance of topographic changes postoperatively were determined in eleven eyes which received vitrectomy surgery.
方法 采用德国海德堡公司的视网膜断层扫描仪 (Heidelberg retina tomograph,HRT) ,检测14例黄斑裂孔患者 15只患眼黄斑部视网膜地形图参数 ,并对其中 11只眼行玻璃体视网膜手术前后视网膜地形图差异进行分析。
2.The cell density was 4 500 cells/mm 2 on average. However, two high density areas corresponding to the central retina (CA, 5 800 cells/mm 2) and dorsal retina (DA, 3 200 cells/mm 2) were detected, and a center peripheral graduation (2 200 cells/mm 2 in temporal periphery) was observed. The distribution and number of dACs in the chick retina were discussed in comparison with those of other vertebrates.
平均细胞密度为 4 50 0个 /mm2 ,但在视网膜中央和背侧部分别有中央高密度区 ( CA,580 0个 /mm2 )和背侧高密度区 ( DA,32 0 0个 /mm2 ) ,而视网膜周边部的 d ACs密度低 ,约为 2 2 0 0个 /mm2 (颞侧视网膜 ,TP)
3.[WT5”HZ]Methods [WT5”BZ]To compare the activity of lactate dehydrogenase (LDH), succinate dehydrogenase (SDH) and ATPase in cryopreserved retina with those in fresh retina and to observe the histological and ultrastructural changes of cryopreserved retina.
方法 以酶组织化学染色法测定深低温保存不同时期 (2 75、70 4d)及对照组视网膜琥珀酸脱氢酶 (succinicdehydrogenase ,SDH)、乳酸脱氢酶 (lacticdehydrogenase ,LDH)、腺苷三磷酸酶 (ATPase)活性 ,并观察视网膜组织结构及超微结构改变。
4.The immunlhistochemisttry staining was measured through automatic image analysis technology. Result The expression of iNOS was not edtected in retina of normal and sham－ injury groups,but iNOS positive cells were found in GCL and INL of retina after the optec nerve injury,the espression of iNOS in 7d and 14d were obviosly higher than that in 1d(P< 0.05) .
结果对照组大鼠视网膜 iNOS表达阴性，视神经横断伤后 1～ 14d视网膜 GCL及 INL出现 iNOS阳性表达，且 iNOS表达在损伤后 7d及 14d明显高于 1d(P< 0.05)。
5.Factors affecting the test-retest variability of Heidelberg retina tomograph and Heidelberg retina tomograph II measurements
影响海德堡眼底照相机和海德堡眼底照相机Ⅱ测试-再测试结果变异性的因素
6.After crush 4 weeks recorded F-VEP of both eye again. After anaesthetize the rats , take out their eye balls and a portion of optic nerve, and observe it’s retina and optic nerve with microscope. Depict the appearance of retina and optic nerve, count retinal ganglion cells(RGCs).
伤后4周再次记录大鼠左、右眼的F-VEP,以自身左右眼差值(用Δ表示)为统计量,麻醉后取出眼球及部分视神经,做视网膜及视神经光镜检查,记录视网膜及视神经形态学改变,计数视网膜神经节细胞(retinal ganglion cells, RGCs)。
7.Effects of Physical Factors on Retina Muller Cell (RMC)Retinal Muller cells (RMC) are the major glia cells in retina, they haveproperties of both astrocytes and oligodendrocytes, and are very important inmaintaining normal retinal function and structure such as to support neurons,form retinal -blood barrier, store and buffer K~+ and participate in neuronsynapse transduction.
视网膜Müller细胞是视网膜中最主要的神经胶质细胞，它兼有少突和星形两种胶质细胞的特性，具有维护视网膜的正常结构、营养神经元、构成血-视网膜屏障、储存和缓冲K~+以及参与神经突触传递等多种生理功能。
8.(1) The retina and the choroid were eminenced obviously under the fundus examination 1 hour postoperatively, which areas ranged from 8 to 10 disc diameter (DD) with a clear and smooth border at the surrounding retina and choroid.
(1)经直接、间接眼底镜检查发现术后1小时视网膜及脉络膜呈明显红色隆起，边界清晰、光滑，与周围的视网膜及脉络膜分界明显，出血范围为8～10个视盘直径(disc diameter，DD)；
9.This paper reviews the distribution of DA neurons in retina,the loc alization of DA receptors,the physiologi c roles of DA in the retina and new progress in this study field.
叙述了DA神经元在视网膜的分布、DA受体的定位、DA在视网膜的生理功能以及该领域研究的新进展。
10.Method: Seventy rats were randomly divided into control group, 2% and 4% taurine group(Tau Ⅰ&Ⅱ). After 15 d dietary supplementation, all groups were exposed to 3 000±200 lx cool white light for 24 h. Levels of taurine in retina([Tau]r) and serum ([Tau]s)were measured, and retina morphology and function were observed through light and electron microscopy and scotopic electroretinography (Scot- ERG) respectively.
方法:70只SD大鼠随机分为对照组,2%牛磺酸组(TauI),4%牛磺酸组(TauⅡ),饲料干预15d后光照(3000±200lx),持续24h,光照前后测定视网膜牛磺酸含量([Tau]r)和血清牛磺酸含量([Tau]s),并通过视网膜电图(scotopicelectroretinograph,Scot-ERG)、视网膜组织病理和超微结构变化判定牛磺酸的防护效应。
