[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.
