Experiments show that Ang Ⅱ activates JNK mediated by AT〓, and JNK increases transcription activity of c-Jun by phosphorylating c-Jun amido-terminal, and induces expression of c-Fos gene. c-Jun and c-Fos form transcriptional factor activated protein-1 complex. AP-1 may stimulates genes which correlate with cardiovascular remodeling expression, such as transforming growth factor, collagen type Ⅰ and Ⅲ, skeletal muscle α-actin,β-MHC, atrial natriuretic factor.

实验表明,在心肌和血管平滑肌细胞Ang Ⅱ通过AT〓介导激活JNK;JNK通过磷酸化c-Jun氨基末端增加c-Jun的转录活性并诱导c-Fos基因表达,c-Jun和c-Fos蛋白形成转录因子复合物激活蛋白-1(AP-1),并刺激各种心血管重塑相关基因如转化生长因子-β1(TGF-β1)、Ⅰ,Ⅲ型胶原、骨骼肌α-actin、β-MHC(β-myosin heavy chain,β-肌球蛋白重链)、心钠素的表达。

Based on the frequencies scaled by 0.96 and the principle of statistic thermodynamics, the thermodynamic properties were evaluated, which were linearly related with the number of nitro and amino groups as well as the temperature, obviously showing good group additivity.

对谐振频率以0.96进行标度后基于统计热力学原理求得它们的热力学性质,探讨了热力学性质随硝基数、氨基数和温度变化的规律,发现有很好的线性关系,体现了很好的基团加和性。

The percentage of through the platform position was calculated. The learning and memory behavior was observed mainly in rats of every group. After the experiment, sodium pentobarbital was injected by intraperitoneal injection of all the rats for anesthesia, and the blood was gained from heart.The plasmcortisol and adrenocorticotrophic hormone were detected by the radioimmunoassay.

取模型组大鼠8只,对照组大鼠5只,不经灌注固定,冰台上迅速分离大脑,将大脑沿矢状缝分左右半球,左半球用于糖皮质激素受体mRNA原位杂交,右半球采用薄层扫描法测定谷氨酸和γ-氨基丁酸含量,同时取大鼠左侧肾上腺进行苏木精-伊红染色,观察肾上腺组织形态变化。

Twenty-four hours after the last oral administration, the blood were obtained and used for testing adrenocorticotrophic hormone, cyclic adenosine monophosphate, cyclic guanosine monophosphate, glucose, cholesterol, alanine aminotransferase, urea nitrogen. Results Before taking medicine, model rats' cAMP/cGMP and ACTH were lower than normal rats', and they showed a trend of rise with adding dose. Before taking medicine, model rats' GLU was lower than normal rats'. With adding dose, model rats' GLU increased, however, normal rats' GLU reduced. When taken medium dose white prepared lateral root of aconite, model rats' CHO was higher than normal rats'. Taking medicine made both groups ALT rise, but normal rats' went up more quickly than model rats'. Model rats' BUN was higher than normal rats', and taking low dose or little dose medicine could lead to incline of reduction.

结果 给药前模型组环磷酸腺苷/环磷酸鸟苷和促肾上腺皮质激素低于正常组,随着给药剂量的增加,两者有升高的趋势;给药前模型组血糖低于正常组,随着给药剂量的增加,模型组GLU有升高的趋势,而正常组有下降的趋势;中剂量给药时模型组总胆固醇显著高于正常组;随着给药剂量的增加,2组丙氨酸氨基转移酶均有升高的趋势,且正常组ALT升高的幅度更大;给药前模型组尿素氮高于正常组,低、小剂量给药有降低模型组BUN的趋势。
