Previous findings from our laboratory have demonstrated that simulated microgravity may result in atrophic changes with depressed vasoconstrictor responsiveness in hindquarter vessels , and hypertrophic changes with enhanced vasoconstrictor responsiveness in cerebral arteries of rats 本实验室前期工作已发现，模拟失重可引起大鼠后身动脉血管发生萎缩性改变和收缩反应性降低，而脑部血管则发生肥厚和收缩反应性增强。
In another instant rostovs horse dashed up against the grey horses hindquarters , almost knocking it over , and at the same second rostov , not knowing why he did so , raised his sword , and aimed a blow at the frenchman . the instant he did this all rostovs eagerness suddenly vanished 顷刻之间，罗斯托夫的战马的前胸已碰着那个军官的马屁股，差点把它撞个四脚朝天，就在同一瞬间，罗斯托夫自己也不知为什么，就举起佩刀，照着那法国人劈去。

In this research we have selected 4 pigs which exhibiting obvious muscular hypertrophy in the hindquarters , and 4 pigs with normal phenotype . we extracted total rna from their longissum tissue . part of the clpg cdna have been obtained by rt - pcr , but we did n ' t find the a g substitution as indentified in sheep 在本实验中，我们选取了4头在臀部具有明显肌肉肥大表型的猪和4头正常猪，并从它们的背最长肌中提取了总rna ，通过rt - pcr的方法得到了部分clpg1的序列，但是我们并没有得到a g的单碱基突变。
