Summary

5 months after stenosis of the right renal artery renal cortex catecholamines of hypertensive rats were studied by a fluorescence-histochemical method. Noradrenaline-specific fluorescence of postganglionic adrenergic nerve fibres in the Aa. interlobulares, Arteriolae afferentes and efferentes of the kidney with renal artery stenosis is brighter when compared with normal controls; in the contralateral side the specific fluorescence is strikingly diminished. These findings are interpreted as an expression of the autonomous nerve system reaction to hemodynamic change. Possible relations to the renin-angiotensin-system are discussed.

Zusammenfassung

Mit fluorescenzhistochemischer Methodik wurde das Verhalten der Catecholamine in der Nierenrinde beim experimentellen renalen Hypertonus der Ratte 5 Monate nach Stenosierung der rechten A. renalis untersucht. Auf der Stenoseseite ist die noradrenalinspezifische Fluorescenz in den postganglionären adrenergen Fasern der Aa. interlobulares, Arteriolae afferentes und efferentes gegenüber normalen Kontrollen verstärkt, auf der Kontralateralseite auffallend vermindert. Die Befunde werden als Ausdruck der Reaktion des autonomen Nervensystems auf die veränderte hämodynamische Situation gedeutet. Auf mögliche Verbindungen zum Renin-Angiotensin-System wird hingewiesen.
