متن کاملIntracarotid hypertonic sodium chloride differentially modulates sympathetic nerve activity to the heart and kidney.
Hypertonic NaCl infused into the carotid arteries increases mean arterial pressure (MAP) and changes sympathetic nerve activity (SNA) via cerebral mechanisms. We hypothesized that elevated sodium levels in the blood supply to the brain would induce differential responses in renal and cardiac SNA via sensors located outside the blood-brain barrier. To investigate this hypothesis, we measured ren...

Physiol. 224(Z) : 256-264. 1973.-The effects of baroceptor reflex on the sympathetic nerve activity (SNA) to the skin and kidney were compared in anesthetized cats. Grouped SNA synchronous with cardiac cycle and respiration was not the major pattern in the skin nerve. Wit...
متن کاملDietary sodium modulates the interaction between efferent renal sympathetic nerve activity and afferent renal nerve activity: role of endothelin.
Increasing efferent renal sympathetic nerve activity (ERSNA) increases afferent renal nerve activity (ARNA), which in turn decreases ERSNA via activation of the renorenal reflexes in the overall goal of maintaining low ERSNA. We now examined whether the ERSNA-induced increases in ARNA are modulated by dietary sodium and the role of endothelin (ET). The ARNA response to reflex increases in ERSNA...
