血浆内皮素和一氧化氮与肾性高血压及肾机能的关系

采用放射免疫及生 化方法淀测６０例肾脏病患者血浆ＥＴ和ＮＯ浓度，并进行相关分析。结果示：①肾肘病组血奖ＥＴ－１浓度高于正常对照组（Ｐ〈０．０１）；血祺氏于正常对照组（Ｐ〈０．０１）。②高血压组患者血浆ＥＴ高于非高血压组（Ｐ〈０．０１）。③肾机能不全组血浆Ｅ稿于肾机能正常组（Ｐ〈０．０１），血浆ＮＯ低于肾机能正常组（Ｐ〈０．０５）。④ＥＴ分别与血压、ＢＵＮ及Ｓｃｒ呈正相关，ＮＯ分别与血压、ＢＵＮ及Ｓ

Study on the relationship between plasma endothelin nitric oxide concentration and renal hypertension and renal function]

OBJECTIVE: To investigate the relationship between plasma endothelin(ET), nitric oxide(NO) levels and, renal hypertension and renal function. METHODS: The plasma concentration of ET-1 was detected by immunofluorescence assay. The plasma concentration of NO was detected by biochemistry assay. RESULTS: 1. In renal disease patients, plasma concentration ET-1 was markedly elevated, and plasma concentration of NO was decreased, compared with the healthy subjects(P < 0.01). 2. Plasma concentration of ET-1 was markedly increased and plasma concentration of NO was decreased in the patients with renal hypertension. 3. Plasma level of ET-1 was higher, and plasma level of NO was lower in the patients with renal function damage than that of those without renal function damage. 4. BP, BUN and Scr were positively correlated with plasma ET-1, but they were negatively correlated with plasma concentration of NO. CONCLUSION: Plasma ET-1 and NO may play an important role in pathogenesis of renal hypertension; the change of their levels may be related to the progress of these renal diseases.
