查询词典 KA

Days after a convulsant dose of KA, the seizure susceptibility were found in KA+NS group and enhanced in KA+PL017 group, whereas significantly decreased in KA+β-FNA group (p.01).β-FNA prolonged the latency and reduced the stage of seizures in dose-dependent manner.

结果显示，一次给予惊厥剂量KA后7天，KA+NS组的癫癎发作敏感性形成；MORs激动剂组（KA+PL017）动物出现癫癎发作敏感性增强；与上述两组比较，MORs拮抗剂组动物癫癎发作敏感性明显降低（p.01），β-FNA以剂量依赖方式延长癫癎发作的潜伏期、降低发作级别。

The seizure sensitive rats were made by subcutaneous injection of a convulsant dose (10mg/kg) of KA. Normal saline , PL017 or β-FNA were infused constantly into ventral hippocampus of awakened and freely moving animals for 7 days by mini-osmotic pumps. 7 days later, all rats were given subcutaneously with subconvulsant dose of KA.

皮下注射惊厥剂量（10mg/kg）的KA制备颞叶癫癎模型的癫癎发作敏感大鼠，采用微渗透泵技术分别将生理盐水、PL017和β-FNA连续7天恒速注入清醒自由活动的上述动物的腹侧海马内。7天后皮下注射阈下剂量（5mg/kg）KA检测癫癎发作敏感性形成情况。

The epilepsy model induced by kainic acid is a dynamical model condition. 5-7 days after acute seizure episodes induced by a single systemic injection of a convulsant dose (10mg/kg) of KA the rats developed a long-lasting increase in seizure susceptibility and the characteristic histopathological features in the hippocampus similar to human TLE. So the KA model has been a well-known model to study TLE or intractable epilepsy.

颞叶癫癎红藻氨酸（kainic acid，KA）模型具有明确的动态变化过程，一次全身性给予惊厥剂量（10mg/kg）KA诱发SD大鼠急性癫癎发作后5-7天，动物开始出现癫癎发作敏感性长期增强，脑内亦发生与人类颞叶癫癎相似的神经病理、神经生化及神经分子生物学方面的改变，因此被认为是研究颞叶癫癎和难治性癫癎的理想模型之一。

Compare with the curvation forms of synaptic interfac e of control animals and 3days after KA administration animals,the amount of smi le synapses is significantly decresed and the amount of frown synapses is signif icantly increased in the moleculous layer of d entate gyrus 7 days after KA injection.

与对照组及KA注射后3d组相比，KA注射后7d大鼠DG分子层内的突触中，笑型突触所占突触总数的比例显著减少，愁型突触所占突触总数的比例显著增加。

The most impressive climatic shock over the past 60 ka was a great thermal and wet event that happened roughly from 37 ka BP to 32 ka BP and was evidently manifested within both the Beihais and the Napahais sedimentary sequences. Discordantly, that event cannot be recognized in the marine records.

大约发生于37~32 ka BP的强大的暖湿型气候事件在北海与纳帕海盆地的沉积序列之中反映突出，成为过去60 ka间最引人瞩目的现象，但是却缺乏海域记录的有力呼应。

The relative acidities of acids and bases are commonly expressed in terms of pKa =- log10 Ka, where Ka is the dissociation constant for the reaction

酸和碱的相对酸度通常可以用pKa =- log10 Ka来表述，那里Ka是反应的解离常数

PROGRAMME: Development of Ka-27/32 began 1969; first flight of common prototype 1973; first Ka-32 (SSSR-04173) flew 8 October 1980; prototype of utility version shown at Paris Air Show June 1985; new military versions first exhibited at Moscow Air Show '95; Ka-32S and Ka-32T versions in production by KAPP; other conversions by Kamov at Lyubertsy.

方案：1969年开始的Ka-27/32发展；共同原型1973年首次试飞，第一家32（SSSR - 04173）飞1980年10月8日；实用版原型在巴黎航空展上展示1985年6月，新的军事版本首次展出在莫斯科航空展'95；家32S号和生产嘉- 32t电磁版本由卡普；由卡莫夫其他转换在柳别尔齐。

According to the idea of uplift early, it can be calculated that the old moraine was formed in 459.42 ka BP, the glacial rock surface was formed in 122.5 ka BP and the roche moutonnee was formed in 18.3 ka BP.

根据80万年来的阶段性的隆升速率介于0.133 cm/a – 0.4 cm/a之间，计算出老终碛垄的形成年代为564.96 ka－656.27 ka，取值为610±50 ka；冰蚀基岩面的形成年代为130.85 ka－149.37 ka，取值为140±9 ka；羊背石的形成年代为18.494 ka－18.790 ka，取值为18.6±0.2 ka。

Four rapid depositional periods such as 12.3~12.1 ka BP, 7.5~7.3 ka BP, 5.9~5.2 ka BP, and 1.5~1.3 ka BP disclosed by Core EC2005 well correspond to the worldwide Younger Dryas, 7.3 ka cold event, Neoglaciation or 5.5 ka cold event, and 1.4 ka ice rafted debris event, respectively. The worldwide 8.2 ka event is also well recorded in the core.

东海内陆架浙-闽沿岸泥质带EC2005孔存在的4个百年时间尺度上快速沉积事件：12.3~12.1 ka BP、7.5~7.3 ka BP、5.9~5.2 ka BP和1.5~1.3 ka BP，与新仙女木事件、7.3 ka BP冷事件、第二新冰期(5.5 ka BP强降温事件)以及北大西洋1.4 ka BP浮冰事件均有良好的对应，世界范围内广泛存在的8.2 ka冷事件对本钻孔沉积也形成了一定影响。

During this period, variance contribution rate of quasi 100 ka cycle is up to 37.44%, and quasi 100 ka cycle has a leading role.

P。也发现地球轨道三要素中的偏心率准100 ka周期2、1 ka岁差周期及55 ka、8.3 ka、3.5 ka非轨道准周期，偏心率准100 ka周期具有主导地位（方差贡献率达37.44%）；3尽管黄土记录的东亚夏季风100 ka周期的产生机制已有多种假说，古气候学界还是普遍认为它产生于某些尚不清楚的过程，有待进一步研究。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
