Lateral parabrachial nucleus and angiotensin II-induced hypertension.
The objective of this study was to determine if ablation of the lateral parabrachial nucleus (LPBN) would prevent angiotensin II-induced hypertension in rats. Thirteen male Sprague-Dawley rats were studied. Bilateral electrolytic lesions in the LPBN were produced in six rats; the remaining seven rats were subjected to sham lesion surgery only. All rats were instrumented with vascular catheters ...
متن کاملLateral parabrachial nucleus modulates baroreflex regulation of sympathetic nerve activity.
Previous studies have demonstrated that the lateral parabrachial nucleus (LPBN) is an important site for descending modulation of baroreflex control of heart rate. In the present study it was hypothesized that the LPBN neurons may also modulate baroreflex control of arterial pressure and sympathetic nerve activity. In urethan-anesthetized rats, electrical or chemical activation of the LPBN prod...
متن کاملSerotonergic mechanisms of the lateral parabrachial nucleus and cholinergic-induced sodium appetite.
Central cholinergic mechanisms are suggested to participate in osmoreceptor-induced water intake. Therefore, central injections of the cholinergic agonist carbachol usually produce water intake (i.e., thirst) and are ineffective in inducing the intake of hypertonic saline solutions (i.e., the operational definition of sodium appetite). Recent studies have indicated that bilateral injections of ...
متن کاملPeptides that Regulate Food Intake An orexigenic role for -opioid receptors in the lateral parabrachial nucleus
Wilson, John D., Danielle M. Nicklous, Vincent J. Aloyo, and Kenny J. Simansky. An orexigenic role for -opioid receptors in the lateral parabrachial nucleus. Am J Physiol Regul Integr Comp Physiol 285: R1055–R1065, 2003; 10.1152/ajpregu.00108.2003. The pontine parabrachial nucleus (PBN) has been implicated in regulating ingestion and contains opioids that promote feeding elsewhere in the brain....
متن کاملNatriorexigenic effect of baclofen is reduced by AT1 receptor blockade in the lateral parabrachial nucleus
GABA(A) and GABA(B) receptors activation with agonists muscimol and baclofen, respectively in the lateral parabrachial nucleus (LPBN), induces water and hypertonic NaCl intake in rats. The purpose of this study was to examine the effects of previous injections of losartan (AT(1) angiotensin receptor antagonist) into the LPBN on 0.3M NaCl and water intake induced by baclofen injected bilaterally...
