Cholinergic stimulation of the hypothalamus and natriuresis in rats: role of the renal nerves

American Journal of Physiology-Renal Physiology, 1986
The role of the renal nerves in the natriuresis seen after cholinergic stimulation of the hypothalamus was studied in anesthetized rats treated with injection into the lateral hypothalamus (LH) of 1 microgram of carbamylcholine chloride (carbachol) in 1 microliter of 0.15 M NaCl or NaCl alone.

Time dependence of mechanisms in the renin response to renal nerve stimulation

Journal of the Autonomic Nervous System, 1983
The renin release responses to 1 and 5 min of renal nerve stimulation were determined. The left kidneys of alpha-chlorolose-anesthetized cats were pump perfused with blood while stimulating the decentralized renal nerves at different frequencies (0.5 ms, 10 V).

Mechanism of renin release during renal nerve stimulation in dogs

Scandinavian Journal of Clinical and Laboratory Investigation, 1981
During renal nerve stimulation, a predominant vasoconstrictory effect on small arteries would lower blood pressure in the afferent arterioles and induce arteriolar dilation and renin release by the autoregulation mechanism. This hypothesis was examined in anaesthetized dogs by stimulating renal nerves at 4 Hz which permitted continuous reduction of ...

Renal nerve responses to cardiac receptor stimulation with bradykinin in monkeys

American Journal of Physiology-Renal Physiology, 1983
Previous data from our laboratory demonstrated a species difference between the cat and dog in the arterial blood pressure (ABP) and renal nerve activity (RNA) responses to epicardial bradykinin (BK) applications. The present study was carried out to determine the ABP and renal nerve responses to chemical activation of cardiac afferents by BK in the ...

Nesfatin-1 stimulates renal sympathetic nerve activity in rats

NeuroReport, 2011
Earlier examination reported that central injection of nesfatin-1 elevated blood pressure and suppressed food intake in conscious rats. In this study, we analyzed the effects of the intracerebroventricular injection of nesfatin-1 on the sympathetic nerve outflow to the kidney in urethane-anesthetized rats.

Afferent renal nerve stimulation excites supraoptic vasopressin neurons

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1985
Single-unit recording experiments were performed in pentobarbital-anesthetized rats to investigate the effects of afferent renal nerve (ARN) stimulation on the activity of neurosecretory vasopressin cells of the supraoptic nucleus (SON). Neurosecretory SON cells were identified by antidromic invasion from the neurohypophysis and classified either as ...

Hypothalamic stimulation and baroceptor reflex interaction on renal nerve activity

American Journal of Physiology-Legacy Content, 1971
The basal level of mean renal nerve activity (MRNA-0) measured in anesthetized cats was found to be modified by the additive interaction of hypothalamic and baroceptor reflex influences. Data were collected with the four major baroceptor nerves either intact or cut, and with mean aortic pressure (MAP) either clamped with a reservoir or raised with l ...

Differential responses in adrenal and renal nerves to CNS osmotic stimulation

Brain Research Bulletin, 1996
Hypertonic solutions act in the central nervous system (CNS) to increase mean arterial blood pressure (MAP) by activation of the sympathoadrenal axis. However, adrenal nerve activity (pre- and postganglionic nerve fibers) has not been determined during central osmotic stimulation.

Effect of stimulation of afferent renal nerves on plasma levels of vasopressin

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1987
Experiments were done in alpha-chloralose-anesthetized, paralyzed and artificially ventilated cats with vagus, cervical sympathetic, aortic depressor, and carotid sinus nerves cut bilaterally to investigate the effect of afferent renal nerve (ARN) stimulation on circulating levels of vasopressin (AVP).

Renal nerve and cardiovascular responses to cardiac receptor stimulation in rabbits

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1988
It has been shown that a species difference exists among cats, dogs, and monkeys in the reflex response to cardiac sympathetic afferent stimulation with bradykinin (BK). This study was performed to determine the arterial blood pressure (ABP), heart rate (HR), and renal nerve activity (RNA) responses to epicardial BK applications in the intact and ...
