The Effect of Nucleus Tractus Solitarius Nitric Oxidergic Neurons on Blood Pressure in Diabetic Rats
It has been shown that nitric oxide is synthesized in the central nervous system as well as in vascular endothelial cells. Recently, it was reported that nitric oxide was involved in central cardiovascular regulation, baroreflex modulation, and involved in a reciprocal release with excitatory amino acids in the nucleus tractus solitarii of rats. The purpose of the present study was to investiga...
متن کاملCharacterization of the sympatho-facilitative area postrema pathway.
1. The mechanism by which the area postrema augments central sympathetic drive during electrical stimulation is presently unknown. This pathway may involve either direct facilitation of brain-stem vasomotor neurons or inhibition of the sympatho-inhibitory baroreceptor relay in the nucleus tractus solitarii. 2. The present study employed selective lesions within the solitary tract nucleus to ass...
متن کاملQuantitative distribution of angiotensin II binding sites in rat brain by autoradiography.
Angiotensin II binding sites were localized and quantified in individual brain nuclei from single rats by incubation of tissue sections with 1 nM 125I-[Sar1]-angiotensin II, [3H]-Ultrofilm autoradiography, computerized microdensitometry and comparison with 125I-standards. High angiotensin II binding was present in the circumventricular organs (organon vasculosum laminae terminalis, organon subf...
متن کاملتحریک الکتریکی هسته دسته منزوی ، حساسیت بارورفلکس را در رت های معتاد به مورفین افزایش می دهد
The previous studies have shown that the endogenous opiate system depress the baroreflex sensitivity in morphine dependent persons. Nucleus Tractus Soloitarii(NTS) is the main termination site of baroreceptor afferent neurons. The aim of this study was to determine the role of electrical stimulation of Nucleus Tractus Soloitarii on baroreflex sensitivity in morphine...
متن کاملPurinergic receptors in the brainstem mediate hypotension and bradycardia.
Adenosine acts at many sites to modulate neuronal activity. The purpose of this study was to investigate a possible role for adenosine as a neuromodulator of brainstem cardiovascular control. Microinjections of adenosine (0-2.3 nmol) were made stereotaxically into various brainstem sites. Injection of adenosine into the nucleus tractus solitarii (NTS) produced dose-related decreases in heart ra...
