ACEI治疗肾性高血压和对肾机能的保护作用

The protection of renal function in the ACEI treatment of renal hypertension]

OBJECTIVE: To explore the influence of angiotensin-converting enzyme inhibitors (ACEI) on plasma endothelin (ET-1), nitric oxide (NO) and renal function in renal-hypertension patients. METHODS: Sixty renal-hypertension patients (Group II) were treated with ACEI (lotensin) for 10 weeks then we measure their blood pressure (BP), plasma ET-1, NO and renal functions (BUN, Scr and proteinuria) before and after the treatment. Thirty healthy persons (Group I) acted as control. RESULTS: The level of plasma ET-1 was higher and plasma NO was lower in Group II than those in Group I. After the treatment of ACEI plasma ET-1 and proteinuria were decreased (P < 0.01), and NO increased in Group II significantly (P < 0.01), while BUN and Scr decreased in abnormal-renal function patients (Group II2) (P < 0.05, P < 0.01). CONCLUSION: The Study indicates that: ACEI is effective to renal hypertension; it decreases plasma ET-1 and increases NO in the renal hypertension patients; ACEI may play an important role in protection of renal functions and prolonging the chronic renal failure.
