Furthermore, abnormal morphology, shrinkage and reduced density of dendritic spines and defects in LTP were observed in brains of the patients suffering from mental retardation and neurodegenerative diseases; many mutant genes found from these patients encode component proteins of signal transduction for neuronal plasticity. These studies on synaptic plasticity would certainly promote making the effective prevention and treatment procedures for mental and neurodegenerative diseases.

此外，在精神迟滞性疾病和神经退行性疾病患者脑内记录到异常的LTP，并发现神经元的树突棘数量减少，形态上产生畸变或萎缩，同时发现，产生突变的基因大多编码调节突触可塑性的信号通路蛋白，故突触可塑性研究也将促进精神和神经疾病的预防和治疗。

In the collembolan community, Sinella, Onychiurus, Isotomurus are the dominance species, the frequencies are 37.26%, 31.6%,and 21.23%, respectively.2.In the agricultural ecology of Fuyang, the dominant species are Collembola and Acari. Their frequencies are 66.37% and 16.72%, respectively. Liposcelididae, Ceratopogonidae, Chironomidae, Staphylinidae, Nematoda, Enchytraeidae are common species.

弹尾目昆虫对重金属污染的反应，不同的种之间有很大的差别，其中，裸长角属对Cu污染反应不灵敏，陷等属、棘属对Cu污染反应敏感，随着污染程度的加剧，它们的数量明显减少；小等属和长属对Cu、Zn、Cd、Pb等重金属元素的复合污染反应很敏感，而裔符属、球圆属、土属、圆属和鳞长属对重金属复合污染反应很迟钝，在这些重金属复合污染严重的农田中仍能很好地生存繁衍。

All 1232 individuals collected could be classified into 3 phyla, 10 classes, and 16 orders. The dominant genera are Acari, Collembola and Hymenoptera, and the common genera is Heteroptera. Their frequencies are 41.07%, 17.21%, 35.23% and 2.11%, respectively. The rare genera included Corrodentia, Enchytraeidae, Isopoda, Diptera, Pauropoda, Symphyla, Araneae, Diplopoda, Lumbricidae, Nematoda, Coleoptera, Chilopda and Lepidoptera.

Under stimulation of glutamic acid, [Ca2+]i in soma increased from 100 nM to 1 μM, and [Ca2+]i in spines increased from 50 nM to 300 nM. These results prove that monitoring calcium concentration in spine with Cameleon is feasible.

吹加谷氨酸来研究了神经元的胞体和树突棘的钙动力学，在100 μM 的谷氨酸的刺激下胞体内钙离子浓度从100 nM 上升到1 μM 左右，而树突棘内钙离子浓度从50 nM 上升达到500 nM。

METHODS The pollu-tive status of Acanthamoeba of drinking water and cornea contact lens preservation box and preserved liquid of college students in Yanji were studied.103drinking water samples and93cornea contact lens preserved liquid and the cleaning liquid were inoculated on the surface of non-nutrient agar plates that contained heat-killed E.coli.

Prevalence of echinococcosis in dogs and sheep was recorded yearly.

实施控制措施后，每年在试验区检测犬的细粒棘球绦虫和绵羊的棘球蚴感染率，以评价驱虫效果。

It can be used in studying the calcium dynamics, in addition it\'s applicable for real-time, less damage and long-playing observation. It might be important to study calcium of spine with stimulations of neurotransmitter and action potential.

结果表明，利用Cameleon 的FRET 比值变化来定量监测树突棘钙动力学的方法是切实可行的，并可以进行实时、无损、长时间的监测，为研究神经递质、动作电位等刺激对树突棘内钙信号影响提供一种重要研究手段。
