Baroreceptor dysfunction in acrylamide axonal neuropathy. 1990

Clinical studies suggest that baroreceptor dysfunction may occur in peripheral neuropathies but this abnormality has never been observed directly or characterized. Carotid sinus nerve and depressor nerve activity was recorded in rabbits with a mild axonal neuropathy produced by acrylamide. Arterial pressure was changed by altering intravascular volume. The pattern of baroreceptor discharge in the affected animals was always different, there being a marked reduction of diastolic phase nerve activity at normal arterial pressures. In addition, nerve activity in both baroreceptor nerves was significantly reduced. The thresholds of aortic arch baroreceptors were elevated and aortic arch baroreceptor activity was less than carotid sinus baroreceptor activity at lower arterial pressures. In acrylamide axonal neuropathy, even when mild, there is baroreceptor dysfunction.

D010525	Peripheral Nerves	The nerves outside of the brain and spinal cord, including the autonomic, cranial, and spinal nerves. Peripheral nerves contain non-neuronal cells and connective tissue as well as axons. The connective tissue layers include, from the outside to the inside, the epineurium, the perineurium, and the endoneurium.

D002346	Carotid Sinus	The dilated portion of the common carotid artery at its bifurcation into external and internal carotids. It contains baroreceptors which, when stimulated, cause slowing of the heart, vasodilatation, and a fall in blood pressure.	Sinus, Carotid
