objective to study gastrodia elata blume to effect tau protein,sod,mda expression in gyrus hippocampi and cerebral cortex of experimental mice.methods to inject okadaic acid to mice ventriculus lateralis and to measure tau protein level,sod activity and lipid superoxide mda content of sod control group,oa injection group,oa and gastiodia elata injection solution group.results tau protein of experimental group(p＜0.05/p＞0.05),sod was lower than model group(p＜0.001) and was higher than control group(p＜0.05).conclusion gastrodia elata blume can increase sod activity and reduce tau protein expression and superoxide lipid forming in brain tissue of experimental dementia mice caused by oa.it can prevent and treat ad.

目的 观察天麻对痴呆模型大鼠海马、皮质神经元微管相关蛋白、超氧化物歧化酶和脂质过氧化物丙二醛表达的影响，探讨其治疗阿尔茨海默病(alzheimer disease，ad)的作用机制。方法用冈田酸(okadaic acid，oa)注射大鼠侧脑室造模，测定模型组、实验组、对照组海马和皮质tau蛋白、sod、mda的含量。结果实验组tau蛋白低于模型组(p＜0.001)，高于对照组(p＜0.05)；sod高于模型组(p＜0.001)和对照组(p＜0.05)；mda低于模型组(p＜0.001)，高于对照组(p＜0.05)。结论天麻可增强oa致实验性痴呆大鼠脑组织sod活性，降低mda蓄积和tau蛋白生成，具有防治阿尔茨海默病的作用。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
