We got the result: Bufo Raddei Strauch Tadpole (1) Bufo Raddei Strauch Tadpole was capable of lens regeneration, which originated from the epithelial cells at iris dorsal margin by dipigmentation.(2) Dipigmentation of Bufo Raddei Strauch by two methods: one was licked up by amoebocyte, the other one was flowed from the pigment cells.(3) In the lens regeneration cells of Bufo Raddei Strauch profiles of the mitochondria became complicated ribosome manifold, and the endoplasmic reticulum was cisternal dilation. During the process of deferentiation of lens fiber the cell nucleolus became little and chromatin shrinked.(4)The crystalline electrophoresis of Bufo Raddei Strauch Tadpole lens regeneration showed that during lens regeneration P-crystalline was expressed earliest then was γ-crystalline and α-crystallin, this result is consistent with newt.

结果表明：花背蟾蜍蝌蚪(1)具有晶状体再生的能力，其晶状体的再生来源于虹膜背缘的上皮细胞；(2)虹膜背缘去色素是转分化的前提，主要有两种方式：一种也是最主要的方式是在晶状体被摘除后虹膜外侧产生巨噬细胞，巨噬细胞吞噬虹膜色素上皮细胞中的色素颗粒；另一种方式是虹膜色素上皮细胞自身释放色素颗粒；(3)电镜观察发现虹膜色素上皮细胞转分化过程中线粒体有明显变化，核糖体增多，粗面内质网增多，晶状体纤维分化过程中细胞核逐渐凝聚；(4)SDS-PAGE电泳发现，花背蟾蜍蝌蚪晶状体再生中相关蛋白表达顺序与有尾类蝾螈相似，蛋白表达顺序依次是β-晶状体蛋白、γ-晶状体蛋白和α-晶状体蛋白，并且后两种蛋白几乎同时表达。

If you wish to set up a 2.40 rig using an A-lens (I am weary of typing out the phrase "anamorphic lens" so henceforth it shall be A-lens, or simply lens if the context is clear), the HC6800 has the capability of switching back and forth between 2.40 format movies or 16:9 material without moving the A-lens.

如果你想建立一个2.40钻机使用A -镜头（我厌倦输入4个字"变形镜头"，因此今后应是A镜头，或只是镜头如果上下文是明确的），该HC6800拥有2.40之间的交换格式的电影或16：9的材料不来回移动的A镜头的能力。

In our experiments, when the opacity of lens exceed Ⅳ degrees, the treatment effect of medicine was not obviously. Analyzing the examined results of AR, SOD and GSH-px in rat lens cortex and nuclear shows that Zhangming drops can inhibit the activity of AR obviously and prevent the translation of galactose to galactose alcohol. So it can prevent the deposit of galactose in the fibrocyte of lens and the increase of lens's osmosis, then prevent the hydration of lens.

Each medicine used in the study totally has obivious effect on lens sodium-pump. Either on the molecular and cellular level or on the histological and organic level , they all have their distinctive demonstration. 1.Ouabain、Digoxine、DMSO decrease the expression of αsubunit of sodium pump on mRNA level , the cell morphology and ultramicroscopic structure demonstrated destructive effect,it indicates the cause of cataract of the medicines.2.D-thyroxine、Amphotericin B、Vitamin E increase the expression of αsubunit of sodium pump on mRNA level ,from the demonstration of the cell morphology and ultramicroscopic structure ,it indicates the medicines have protective or anti-distructive effect on lens.3.The medicines have isoform-specific action on lens sodium-pump,it indicates exploitting isoform-specific medicine has a promising clinical application.4. Lens sodium-pumps are inhibited probably lead to cataract, so in clinical medication, especially to the cardiovascular doctor, while he is using the sodium-pump inhibitors, he should pay more attention to adjust the dosage and duration of the drug therapy. 5. To creat the animal model of cataract through inhibiting lens sodium-pump, whether it can be a kind of classical method or not, it is worthy of further research.

本研究所选用的药物对晶状体钠泵均有明显的影响作用，在分子水平、细胞水平、组织器官水平均有特异的表现：1、哇巴因、地高辛、二甲基亚砜三种药物可降低晶状体钠泵α亚单位在 mRNA水平的表达，在细胞形态和超微结构上表现为损伤效应，提示了其潜在的导致白内障的可能。2、D甲状腺素、两性霉素B、维生素 E三种药物可升高晶状体钠泵α亚单位在 mRNA水平的表达，从细胞形态和超微结构上的表现，提示了其对晶状体有保护作用或抗损伤效应。3、药物作用于晶状体钠泵具有重整异构特异性，提示了开发出特异的具有重整异构作用的药物是极有临床应用前景的。4晶状体钠泵抑制后可能导致白内障的发生，故临床用药，尤其是心内科医生在使用这些钠泵抑制剂时应注意调整用药剂量及药物疗程。5 通过抑制晶状体钠泵来制作白内障动物模型能否成为一种经典的制作方法，还有待于进一步研究。
