查询词典 ka

This study demonstrated that KA administration in a convulsant dose could result in spontaneous recurrent seizures and permanent disturbances of behavior and cognition in old rats (P25、P60) which brains were in mature. However temporal and reversible effects occurred in rat pups (P5、P15) in immature brain.

一次给予惊厥剂量的KA可诱发脑发育成熟大鼠（P25、P60）出现自发癫痫发作，但在脑发育未成熟大鼠（P5、P15）中未见有自发癫痫发作；KA致痫对脑发育成熟大鼠造成的认知行为异常持久而不可逆，但对脑发育未成熟幼鼠认知行为的影响则持续时间短而可逆。

ABP. Sedimentation rate is very low on the whole core and shows three apparent variations at three phases:① A comparatively high SR during marine isotope stage 3 (MIS3) and LGM, about 7.3 and 14cm/ka respectively;② A very low SR of 1.5cm/ka during the last deglaciation, which is different from the deeper Okinawa Trough with higher SR during the last deglaciation than the last glaciation;③ A negligible sediment accumulation since 6.4 cal.

DOC-42孔沉积速率整体较低，呈明显的阶段性变化：在氧同位素3期和LGM期间沉积速率相对较大，分别为7.3和14cm/ka；末次冰消期以来的沉积速率则显著降低，与冲绳海槽冰后期沉积速率高于末次冰期明显不同；自约6.4 cal。

Methods: Experimental rats were injected with KA (10mg/kg, 5mg/ml) subcutaneously to make status epilepticus model. SE latter 10 day, Use subliminal dosages KA to check falling sickness paroxysm sensibility model; SE latter 10 day , Morris water maze was to evaluate cognitive function in the animals. Changing NPY adopt immunocyte chemistry method to check the rat brain inner is expressed.

本研究给Sprague-Dawley大鼠颈部皮下注射惊厥剂量的红藻氨酸(KA，10mg/kg，5mg/ml)，诱发癫痫持续状态(status epilepticus，SE)， 10天后，用阈下剂量的KA检测癫痫发作敏感性模型；10天后用Morris水迷宫实验检测动物学习记忆功能变化；用免疫组化技术检测动物海马CA1区CA3区NPY表达的变化。

To our interest, the pairwise comparison of species in Hominoid suggested a higher Ka / Ks ratio than that in the Old World M onkey or between the Old World m onkey and marmoset, which showed existent of different pattern of evolution.

有趣的是，人猿超科两物种比较呈现较高的Ka/Ks比值，但在旧大陆猴中及旧大陆猴与狨猴间的Ka/Ks比值显著低于人猿超科的，呈现很不同的格局。

Methods All rats were divided into KA group, vagus nerve stimulation+KA group and the control group.

Of these, Colletotrichum (25.54%) was the most prevalent genus, followed by Alternaria (11.56%) and Xylaria (7.80%). The most dominant fungi appeared in the stems from ka (19.89%), ck (19.62%) and ma (18.82%), while the least appeared in the fruits from ka (5.11%) and ku (6.18%).

各组织获得菌株数量比例最大的分别为ka种源茎部(19.89%)、ck种源茎部(19.62%)和ma种源茎部(18.82%)；最小的为ka种源果实部(5.11%)和ku种源果实部(6.18%)。

In GABA group,the degeneration and necroses of hippocampus neurons were relatively alleviated.The positive expression of CX43 mRNA was few in control group and surgery group.And in KA group it increased with time.In GABA group,the positive expression of CX43 mRNA was fewer than that of KA group at every period.

CX43表达阳性细胞数定量分析显示，正常及手术对照组CX43表达阳性细胞数较少，KA对照组随时间延长CX43阳性表达细胞数逐渐增多， GABA受体基因转染组大鼠CX43阳性表达细胞数在各个时程均比KA对照组减少。
