Cholecystokinin selectively affects presympathetic vasomotor neurons and sympathetic vasomotor outflow.
Cholecystokinin (CCK) is a potential mediator of gastrointestinal vasodilatation during digestion. To determine whether CCK influences sympathetic vasomotor function, we examined the effect of systemic CCK administration on mean arterial blood pressure (MAP), heart rate (HR), lumbar sympathetic nerve discharge (LSND), splanchnic sympathetic nerve discharge (SSND), and the discharge of presympat...
متن کاملMecamylamine selectively blocks nicotinic receptors on vasomotor sympathetic C neurons.
Mecamylamine differentially blocked fast nicotinic transmission in two functional subsets of sympathetic neurons within lumbar paravertebral ganglia of the bullfrog. EC50s for inhibition of postsynaptic compound action potentials were 27.3+/-2.5 microM in the secretomotor B system and 5.7+/-0.7 microM in the vasomotor C system. This 5.2:1 selectivity is 2.6 times greater than observed previousl...
متن کاملsympathetic skin response and vasomotor symptoms in postmenopausal osteoporotic women
background: osteoporosis is a common disease characterized by reduction in bone mass, due to depletion of calcium and bone protein. a pivotal role of the sympathetic nervous system in bone remodeling has been considered. on the other hand, elevated central sympathetic activation in postmenopausal women is involved in the creation of vasomotor symptoms. also, sympathetic skin response (ssr) has ...

متن کاملDifferential Sympathetic Vasomotor Activation Induced by Liver Cirrhosis in Rats
We tested the hypothesis that there is a topographical sympathetic activation in rats submitted to experimental cirrhosis. Baseline renal (rSNA) and splanchnic (sSNA) sympathetic nerve activities were evaluated in anesthetized rats. In addition, we evaluated main arterial pressure (MAP), heart rate (HR), and baroreceptor reflex sensitivity (BRS). Cirrhotic Wistar rats were obtained by bile duct...
