神经干细胞的单层培养及分化过程中ＨＥＳ１和ＭＡＳＨ１的表达变化
Zhongshan Daxue xuebao. Yixue kexue ban, 2014 摘 要： 【目的】 建立神经干细胞（ＮＳＣ）体外培养方案，使ＮＳＣ的体外可以得到增殖和分化，并检测ＮＳＣ分化过程中ＨＥＳ１和ＭＡＳＨ１的表达变化。【方法】无菌条件下取ＳＤ大鼠胚胎端脑，无血清悬浮培养，形成Ｐ２代神经球后，将神经球消化成单细胞，分为神经球悬浮培养和单层贴壁培养，并对两种不同培养方式下的ＮＳＣ进行干性鉴定和分化能力鉴定。用不同浓度（２０、４０、８０ μｇ／Ｌ）的脑源性神经生长因子（ＢＤＮＦ）诱导ＮＳＣ分化，选出最合适的浓度。用ＢＤＮＦ最佳诱导浓度诱导ＮＳＣ分化，Ｑ ...

Shuitu Baochi Xuebao, 2000 根据合肥近郊旱地连续３年的实地观测和采样分析数据，对不同降雨强度下径流携带泥沙量和各种养分含量进行统计、分析和对比，揭示了各种养分流失与降雨强度的关系和流失行为，初步查明了旱地耕作层表土和养分的流失在不同降雨强度下的不同表现。表土和有机质的流失与雨强基本呈正相关，以径流冲刷作用为主；氮磷钾养分的流失则以径流溶蚀为主，但情况比较复杂，特别是通过“径流溶蚀”流失的养分与雨强并不是简单的正比关系 ...

Shuitu Baochi Xuebao, 2007 对1.5～4.5年生厚荚相思人工林5种营养元素(N、P、K、Ca和Mg)的含量、积累、分配和生物循环以及它们随林分年龄的变化趋势进行了研究.结果表明,厚荚相思人工林不同器官中营养元素含量排序大致为树叶＞于皮＞树枝＞树根＞干材,林木各器官中营养元素含量均以N最高,其次是Ca,然后是K和Mg,P最低;厚莫相思人工林营养元素贮存量依次为145.00～611.70 kg/hm2,随生长过程中生物量的增加而增大;不同器官微量元素贮存量的分配随林分年龄的增长发生变化,1.5年生时营养元素贮量主要集中在树叶和树枝,2.
