摘要
为转换酶抑制剂(ACEI)治疗高血压提供理论依据。方法25例高血压患者按内生肌酐清除率分为肾功能正常10例,代偿8例和氮质血症7例3组。观察ACEIenalapril(10~30mg/d)4周对血管活性物质,包括血浆肾素活性(PRA),血管紧张素Ⅱ(ATⅡ),转换酶(ACE),心钠素(ANF),尿醛固酮(Aldo),缓激肽(BK)和前列腺素E2(PGE2)的作用。结果1.服药前3组患者与正常人比,ATⅡ升高,PRA,Aldo无差异;氮质血症组患者BK降低,ANF增高;2.服药后3组患者ATⅡ,Aldo和ANF下降,BK(除氮质血症组),PGE2和PRA升高;3.治疗后ATⅡ与Aldo、ATⅡ与ANF以及BK与PGE2分别呈正相关。结论1.肾素-血管紧张素系统(RAS)与BK-PGS两系统相互调节在不同肾功能高血压患者的发病中起着作用,并有着治疗意义;2.
