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。

Results The incidence of HFRS complicated by MOF was8.8%and the fatality rate was39.1%,the prime inducement was hemorrhage,the phase was in no uresis and the kidney was prone to lesion.

目的通过建立大鼠感觉神经束近端与运动神经束远端吻合的神经再生模型，观察在靶器官改变时感觉神经的结构与功能发生的可塑性变化。

It is well-known that for eucaryotic cells, DNA is located in the karyon and can not penetrate to the cytochylema and the tissue fluid because the cell membrane can act as barriers for DNA transportation. Therefore, the appearance of DNA in cell matrix and the serum can indicate that some diseases have taken place. A main reason for cancer occurrence is the mutation of DNA. It may cause the change of the sequence and expression of cancer suppressor genes.

真核细胞的DNA广泛的存在于细胞核内的染色体上，由于核膜的选择性通透作用，使DNA无法分散到其它细胞的亚器官，加之细胞膜的隔离效果，DNA更难扩散到细胞外基质中，因此细胞外基质中DNA含量的增加往往也会预示某些疾病的发生。

The investigation of the structures of reproductive organs,megasporogenesis,microsporogenesis and the development of male and female gametophyte in Dendrocalamus sinicus are made using normal paraffin method in this article.

Inductive interactions mediated by the Msx genes are essential for normal craniofacial, limb and ectodermal organ morphogenesis, and are also essential to survival in mice, as manifested by the phenotypic abnormalities shown in knockout mice and in humans.

基因敲除鼠和人类的畸形表现型的研究显示，Msx基因介导的诱导组织间的相互作用，对正常颅颌面、肢体和外胚层器官的形态发生至关重要。

Stress Ulcer indicates that the Superficial mucosal locates stomach、duodenum congests., debaucjeds and cankers acutely. SU usually occurs at the mucosal of gastric bottom and body. along with the development of pathological changes, SU can spread to gastric antrum 、 duodenum, e"en mucosal of oesophagus" s bottom, even presents emanatory focus. Su generally appears to the critical patient of central nerve system damnification severe wounds blood poisoning、 shock、 the functional debility of heart、 lung、 liver、 kidney etc or after the big operation. The occurrence rate of Su in intensive care unit reachs 60%, it is one of the hackneyed severe syndrome in ICU , and its death rate is relatively high.

应激性溃疡(Stress ulcer，SU)是指位于胃、十二指肠的急性表浅性粘膜充血、糜烂和溃疡，通常发生在胃底、胃体部粘膜，随着病变的发展，病变可扩展至胃窦、十二指肠，甚至食管下端粘膜，且呈现散发性病灶，该病多见于中枢神经系统损伤、严重创伤、败血症、休克、心肺肝肾等多器官功能衰竭及大手术后等危重病人，其在重症监护室的发生率达60%，是ICU中多见的严重并发症之一，并有较高的死亡率。
