It is suggested that there are some Glu sensitive neurons in sublayer Ⅱaf of pigeon optic tectum,the most of which show excitation to exogeous Glu.These data observed in slices provide a strong evidence that Glu may act as a neurotransmitter involving in the activity of the sublayer Ⅱaf neurons in pigeon optic tectum.

以上结果提示，家鸽顶盖Ⅱaf亚层内存在Glu敏感神经元，外源性的Glu对这些神经元有兴奋作用，Glu可能作为神经递质参与了家鸽顶盖Ⅱaf亚层神经元的活动。

Dielectric, piezoelectric and electrmechanical coupling properties of PZT and PSZT systems at high Zr content region were studied. The feature of high Kt and low Kp of PZT-based materials near F-AF phase boundary was exploited and examined, and electromachanical coupling anisotropy Kt/Kp is higher than that at the morphotropic phase boundary , Kt≥0.40, Kt/Kp≥3. 0. This phenomenon can be realized by electric field -induced AF-F phase transition and explained by coupling effect of two-sublattice in antiferroelectric unit cell.

研究了PZT和PSZT两个系统在高锆区的介电、压电和机电耦合等性能，首次发现了PZT基材料在铁电-反铁电相界处具有高Kt和低Kp的性质，机电耦合各向异性Kt/Kp也比准同型相界要高，Kt≥0.40，Kt/Kp≥3.0，并把这一现象归因于电场诱导AF-F相变和反铁电双子晶格间的强耦合作用。

Atrial anatomical remodeling, consisting of proliferation of connective tissue and mitochondria, myolysis and glycogen accumulation, could be induced by chronic AF. These changes may contribute to relapse of AF and atrial stunning after conversion of AF to sinus rhythm.

慢性AF能使心房组织发生纤维结缔组织增生、肌纤维溶解、线粒体增生、糖元累积等解剖重构变化，这些改变可能在AF终止后心房顿抑的发生和AF的自身维持中起作用。

The adsorption behaviour of chemically different superplasticizers, such as melamine formaldehyde sulphite polycondensate,β-naphthalene sulfonate formaldehyde polycondensate and polycarboxylate, on early hydrating cement phases was studied. For this purpose, pure ettringite AF(subscript t, monosulfate AF(subscript m and syngenite were prepared. The adsorbed amount and zeta potential of early hydration products were measured.

制备了钙矾石AF(下标 t、单硫型硫铝酸钙AF(下标 m和钾长石类单矿物，并研究了三聚氰胺磺酸盐甲醛缩聚物、β-萘磺酸盐甲醛缩合物及聚发酸盐等几种化学成分不同的超塑化剂在其早期水化颗粒表面上的吸附行为。

The protection of AF－1 was observed with the measurement of transudatory rate of LDH ,the breaking rate of DNA and contents of LPO and SOD,Results:The intotoxincation of glutamate was decreased by AF－1 which reduced the transudatory rate of LDH,the breaking rate of DNA and the content of LPO,and increased the content of SOD in culture significantly.

通过测定乳酸脱氢酶漏出率、DNA断裂率、超氧化物歧化酶和脂质过氧化物，观察AF－1药物的保护作用。结果：高浓度的谷氨酸可增加培养神经细胞的LDH释放率和DNA断裂率，并诱导自由基产生。AF－1明显降低谷氨酸的神经细胞毒性，使LDH释放率及DNA断裂率明显降低，LPO含量明显下降，SOD含量明显升高。

The high BVP percentage reported in the AF group is even more astonishing considering the low use of chronotropic-negative drugs and the lack of use of a ventricular rate regularisation feature, extremely important to ensure biventricular capture in cases of fast irregular rhythm.

在Khadjooi的研究中，在包括阵发性房颤患者的AF的群体中引入了2个重要的偏倚：阵发性房颤患者两心室同步率要高于永久性房颤患者。（AF患者的BVP比例为87%）；阵发性房颤患者的&临床&行为如SR患者。在AF患者群中，接受CRT的正性效果与SR人群相比要差。

METHODS: We performed AF substrate ablation guided by complex fractionated atrial electrogram mapping in 674 high-risk AF patients.
