The results obtained are as follows: (1 ) intrarenal artery injectionof capsaiein (20, 40, and 60 nmol/kg) increased the renal afferent nerve activity (ARNA) in a dose-dependent manner withunchanged arterial pressure; (2) pretreatment with ruthenium red (40 mmol/kg), a capsaicin receptor antagonist, complete-ly abolished the effec.

The purpose of this study was to determine the effect of intrarenal artery injection of L-arginine on multi- and single-unit spontaneous discharges of renal afferent nerve fibers in anesthetized rabbits.

Location of efferent neurons of caecum in fowl;

Objective: Topography oberservation of Hsiakuan point and the location of the afferent neurons and the efferent neurons to provide the morphological foundation for Hsiakuan point acupuncture research.

he present investigation was carried out in anesthetized rat to observe the effects of intrarenal arterial injection of endothelin-1 (ET-1) on mean arterial pressure (MAP), heart rate (HR) and afferent renal nerve activity (ARNA), and to examine the antagonistic effects of a selective (ETA) receptor antagonist.

The effect of stimulation of the renal afferent nerve (RAN) on plasma cortisolconcentrations before and after lesions of paraventricular muceli of hypothalamus(PVN) in chloralose-anethetized cats was investigated.
