To resolve the problem that the concentration of CO2 was hard to control in fields,KHCO3 was sprayed on soybean leaves and NaHSO3 was used to restrain photorespiration at the same time,so as to find the best application amount of KHCO3 and NaHSO3 to increase photosynthetic rate of soybean seedlings.

针对目前还难以控制田间CO2浓度的问题，采用在大豆幼苗叶片上喷施碳酸氢钾(KHCO3)的方法，同时用亚硫酸氢钠( NaHSO3)适当的抑制大豆的光呼吸，来提高CO2浓度进而提高光合速率。

Methods The rabbit model with hyperhomocysteinemia was established by L-methionine subcutaneouse injection. The changes of white microthrombus and microvascular diameter in pia mater microvessel were observed by using cranial window method and closed microcirculation detection system, The concentration of Hcy was detected by high performance liquid, The level of von Willebrand factor, endothelin-1 (ET-1) were assayed by ELISA. The content of NO was measured by nitrate reduction method. Meanwhile, the relationship between the changes of microvascular diameter and blood concentration ET-1, NO was analyzed.

采用L-蛋氨酸皮下注射法建立HHcy家兔模型，应用"颅骨窗口法"和微循环闭路检测系统观察其软脑膜微血管中白微栓数量及微血管口径变化；采用柱前衍生反相高效液相色谱－荧光法检测同型半胱氨酸浓度；平行观测血管内皮功能指标血管性血友病因子抗原（vWF，用酶联免疫吸附法）、血浆内皮素－1ET-1，用ELISA）、血清一氧化氮水平；并对HHcy所致ET-1、NO血液浓度变化和微血管口径变化进行相关分析。

Propofol induced Cl- currents at concentrations of 10-5 and10-4 M, which were sensitive to picrotoxin and, to a lesserextent, to strychnine. Propofol (10-6 M) enhanced -aminobutyricacidA (GABAA; 10-6 M)-induced current synergistically. Moreover,propofol (10-5 and 10-4 M) significantly increased the decaytime of evoked-inhibitory postsynaptic currents, which suggestsa postsynaptic modulation of GABAA receptors.

异丙酚在浓度10-5~10-4M 时，産生 Cl-电流，对印防己毒素敏感，在更小浓度范围内，对番木鼈碱敏感。10-6M 的异丙酚加强 GABAA 産生的电流，另外，异丙酚（10-5、10-4M ）显著地增加了突触后诱发-抑制电流的衰退时间，提示了 GABAA 受体的突触后调节作用。

The concentration of electrolytes in the serum of pika does not be affected by environmental conditions that pika lives.

高原鼠兔血清电解质浓度不受生活环境和食物条件的影响，其机体能自身调节血清离子浓度，以维持电解质在血液中的相对衡定；2。
