METHODS The traditional rat two kidney one clip (2K1C) renal hypertension model was modified and the expression of AT 1a mRNA,AT 1b mRNA was examined by quantitative reverse transcription polymerase chain reaction (QRT PCR).

• 方法 改进传统的两肾一夹肾性高血压大鼠实验模型制作方法 ,采用定量反转录聚合酶链式反应 (QRT PCR)方法对AT1a mRNA、AT1b mRNA进行定量。
