为了能够有效地分析生物大分子在该细胞中的功能作用位点，本研究根据该生物染色体结构的特征，构建了含有红色荧光蛋白的大核人工染色体EoMAC_R，并与之前构建的含绿色荧光的大核染色体EoMAC_G一起，对蛋白质合成终止有关的3个重要因子核糖体大亚基蛋白L11、多肽链释放因子eRF1和eRF3在八肋游仆虫细胞中进行了荧光共定位分析。

In the third chapter, deaggregating ability and inclusion ability of β-cyclodextrin to long-chain alcohol esters of β-naphthoic acids was carried out.

第二章，我们用稳态荧光光谱法研究了双头基两亲型化合物对长链烷基β--萘甲酸酯的解簇集作用；结果发现，解簇集作用不仅依赖于簇集体的起始浓度而且还依赖于溶剂的促簇能力。

Four groups were respectively conducted in Morris water labyrinth test, which was used to dect the learning and memory of rats. Population spike in CA3 region was recorded in vivo following stimulation of lateral perforant path ,For the induction of LTP , 4 trains (50 shocks/ t rain , 500 Hz) high-frequency tetanic stimulations were applied to lateral perforant path.

MK-801组除按依赖组剂量注射海洛因外在每次注射海洛因前30分钟注射MK-801(0.3mg/kg)，四组各自进行水迷宫实验测试大鼠学习记忆；在体记录由刺激海马外侧穿通纤维(lateral perforant path，LPP)，所诱发的CA3区群体峰电位电位，并观察高频刺激引起的LTP效应；用逆转录聚合酶链反应技术半定量检测海马NMDA受体NR1、NR2A亚基mRNA的表达。

Andres, and its mechanism against rot-causing fungi, the antifungal activity and period of pyrolin against Physalospora piricola and Alternaria alternate was evaluated by using agar dilution method, and ultrastructure changes was observed used by scanning electron microscope.
