    Journal: J Urol; 1996 Oct; 156(4):1480-4. PubMed ID: 8808912.
    Abstract:
    PURPOSE: This study tried to assess the possible contribution of the sympathetic nervous system to the onset of two-kidney, one-clip (2K-1C) Goldblatt hypertension. MATERIALS AND METHODS: The effect of chlorisondamine administration with or without subsequent splanchnicotomy on the development of hypertension was examined in 2K-1C rats with special reference to norepinephrine synthesis. RESULTS: The 2K-1C rats were treated either with chlorisondamine or chlorisondamine plus subsequent splanchnicotomy, so that the development of hypertension was effectively arrested for 4 weeks. An apparently high rate of release of norepinephrine in 2K-1C rats was reduced by treatment with chlorisondamine plus splanchnicotomy. A similar trend was also seen in plasma norepinephrine concentration and norepinephrine clearance, to a lesser extent. There were significant positive relationships between percent change of systolic blood pressure and apparent rate of release of norepinephrine, plasma norepinephrine concentration and norepinephrine clearance in 2K-1C rats and 2K-1C + chlorisondamine + splanchnicotomy rats. There were no significant relationships in these parameters in sham-treated rats. CONCLUSION: Increased sympathetic innervation appears to participate in the development of 2K-1C Goldblatt hypertension.
