Impact of single‐walled carbon nanotubes on the medullary neurons in spontaneously hypertensive rats

The effect of single-walled carbon nanotubes (SWCNTs) on the nervous cardiovascular control in normotensive (NTR) and spontaneously hypertensive rats (SHR) was studied. SWCNTs were injected into the medullary nuclei involved in the neural control of the cardiovascular system (nucleus of tractus solitarius (NTS); nucleus ambiguus (AMB), paramedian reticular nucleus (PMn), and lateral reticular nucleus (LRN)). It was found that SWCNT microinjections into all the studied medullary nuclei of both NTR and SHR resulted in a lowering of the arterial pressure more essential in SHR compared to those in NTR.
