The neurotensin immunoreactive (NTIR) in plasma and some brain areas was measured when baroreceptor was excited by depressor nerve stimulation and carotid sinus perfusion.
Its functional mechanism is that Na-citrate has stimulated the carotid sinus through the vagus nerve to the respiratory centre.
其作用机理是枸橼酸钠刺激了颈动脉窦区感受器，通过迷走神经传入呼吸中枢引起的。
