Nitric oxide in rostral ventrolateral medulla regulates cardiac-sympathetic reflexes: role of synthase isoforms.
Our previous studies have shown that nitric oxide (NO) synthase (NOS)-containing neurons in the rostral ventrolateral medulla (rVLM) are activated during cardiac sympathoexcitatory reflexes (Refs. 12 and 13). However, the precise function of NO in the rVLM in regulation of these reflexes has not been defined. Three isoforms of NOS, including neuronal NOS (nNOS), inducible NOS (iNOS), and endoth...
متن کاملCerebrospinal Fluid Hypernatremia Elevates Sympathetic Nerve Activity and Blood Pressure via the Rostral Ventrolateral Medulla.
Elevated NaCl concentrations of the cerebrospinal fluid increase sympathetic nerve activity (SNA) in salt-sensitive hypertension. Neurons of the rostral ventrolateral medulla (RVLM) play a pivotal role in the regulation of SNA and receive mono- or polysynaptic inputs from several hypothalamic structures responsive to hypernatremia. Therefore, the present study investigated the contribution of R...
متن کاملChronic lesion of rostral ventrolateral medulla in spontaneously hypertensive rats.
We studied the effects of chronic selective neuronal lesion of rostral ventrolateral medulla on mean arterial pressure, heart rate, and neurogenic tone in conscious, unrestrained spontaneously hypertensive rats. The lesions were placed via bilateral microinjections of 30 nmol/200 nl N-methyl-D-aspartic acid. The restimulation of this area with N-methyl-D-aspartic acid 15 days postlesion failed ...
متن کاملThe vascular layers on the rostral ventrolateral medulla.
There has been a keen interest in assessing the neurovascular anatomy of the rostral ventrolateral medulla oblongata (RVLM). The present study was aimed at documenting the complete neurovascular anatomy of the RVLM, in order to offer a general picture of the possible offending vessels of this area, which seems to be involved in the pathogeny of the essential hypertension. Noteworthy, syndromes ...
متن کاملPulsatile compression of the rostral ventrolateral medulla in hypertension.
The rostral ventrolateral medulla (RVLM) has been known to be a major regulating center of sympathetic and cardiovascular activities. An association between essential hypertension and neurovascular compression of the RVLM has been reported in clinical observations, including magnetic resonance imaging (MRI) studies. To reconfirm this relationship, we performed MRI using a high-resolution 512 x ...
