METHODS: Left renal artery stenosis in SD rats was established by inserting silver clip with the inner diameter of 0.2 mm or 0.25 mm, while the right renal artery was not received, so as to establish two-kidney one-clip (2K-1C) renal hypertensive models. 方法:SD大鼠左侧肾动脉用0.

Fifteen rats were killed at the end of the 4th and 12th week? respectively after anesthesia. 假手术组(n=30):手术操作除左肾动脉不安置银夹外,余同模型组,于术后4周末及12周末各麻醉处死15只。
