查询词典 NA

The distribution of Na(superscript +) in intracellular and extracellular spaces in leaves of arrowleaf saltbush subjected to salt stresses was investigated by using a scanning electron microscope facilitated with an Auger electron spectrometer. The role of salt bladders in salt resistance of A. triangularis was analysed in terms of salt accumulation and secretion.

玉米根、根颈、种皮的Na积累能力、叶的拒Na能力和幼苗选择吸收Ca(上标 2+)的能力可能与品种耐盐性有关。

The activity of muscle Na+/K+-ATPase was first time combined with that of the gill Na+/K+-ATPase to evaluate the salinity adaptability of the subadult Macrobrachium nipponense acclimated for 1d, 2d, 4d and 8d in different combinations of temperature (15℃, 20℃, 25℃ and 30℃) and salinity (0‰, 7‰, 14‰ and 21‰). Oxygen Consumption Rate and Tissue Water Content were also used for this evaluation.

本文以日本沼虾亚成虾为对象，首次采用将鳃和肌肉中两套Na~+／K~+-ATPase系统结合起来，并辅以耗氧率和组织水测定的方法来研究其在不同温度(15℃，20℃，25℃和30℃)和盐度(0‰，7‰，14‰和21‰)条件组合水体中经过1d，2d，4d和8d适应之后的适应情况。

Male.When the preganglionic nervetrunk was avulsed on one side,the NA content of the gland in both sexes fell to about80% of their unoperated sides,but NA content of th...

切断颈上神经节的节前神经，雌雄腺体的 NA 含量都下降至对照侧的80%左右。

Both IS and NA increased heart rate, while propranolol (Pro, 25#mu#g per min) produced a decrease. Phentolamine (Phen, 25#mu#gper min) had no effect. All these effects were similar in vagotomized as well as in unoperated rats. It was shown that the reversal of the effect of sympathetic nervous system on gastric acid secretion is not due to changes in circulation.

IS和NA增加大鼠心率，心得安(25μg/min)显著地减少它，而酚妥拉明(25ug/min)没有明显的作用；IS， NA、心得安或酚妥拉明对迷走神经完整、VT即刻和三月后的大鼠心率的影响均无差异，表明VT后交感神经系统调节胃酸分泌的作用吃变化并非循环改变的结果。
