Purpose: The objective of our study is to observe the changes in serum of rats so as to evaluate the effect of four kinds of guided bone regeneration(GBR)membranes used in the skull defects of rats.Methods: 45 adult male SD rats were randomly divided into five groups,9 rats in each group.Then two 5mm trephined defects were produced in the skull of each rat.In the four experimental groups,one defect was covered by four different kinds of GBR membranes with the other side as blank control.The fifth group was used as control group while the defects filled with autogenous blood only.After 1,4,8 weeks,the blood samples of rats were taken.The serum were separated and tested,the results showed us the different changes in the alkaline phosphatase(ALP)and calcium concentrations.

我国国产大豆生产成本高、价格高、而劳动效率低、单产低,且最主要的是部分大豆品质下降,品质特性不突出,导致我国国产大豆市场竞争力弱,我国由原来自给自足的大豆生产大国变为大豆对外进口大国。因此,提升大豆的品质成为国产大豆的新出路。有研究表明,外施适宜浓度的稀土元素有利于植株矿质营养的转化和利用、提升大豆品质、增加大豆产量。本试验以东北特有的不同品质型的高蛋白大豆东农42、高脂肪大豆东农47和中间型大豆
摘要：本文根据乔治娅·奥基弗和朱迪·芝加哥为例，分析了女性主义艺术独有的共性之处。在艺术史书中，构成艺术体系的几乎全部是男性，对于女性艺术家的记载少之又少，作品记载更是寥寥无几，在仅有记载得女性艺术家中，她们不仅生存在男性的眼光趣味中，也没有跟从自己的内心，按照自己的意愿去创作。20世纪中后期女权主义运动逐渐引起关注，女性主义意识逐步形成，女性艺术家开始在作品中释放自己的情绪，大胆的表现主观感受，
