摘要:
SUMMARY Alterations in the dynamics of brain serotonin biosynthesis can lead to changes in cardiovascular function. It appears that the activation of cerebral serotonin receptors produces a pressor effect in normotensive rats but produces a depressor effect in nonnotensive cats or dogs. On the other hand, reductions in the levels of serotonin can prevent the onset of hypertension in some experimental hypertensive models and lower the blood pressure of organisms with established hypertension. The ability of brain serotonin to modulate arterial blood pressure may be mediated by the influences of the serotonergic neuronal systems on efferent sympathetic activity. Finally, the reduction in sympathetic outflow produced by increasing brain serotonin levels in dogs protects the heart against ventricular fibrillation and may, therefore, constitute a reasonable adjunct in the management of high-risk, cardiac-arrest patients.
