[Changes in monoamine neurotransmitters in CSF during inhibition of defensive hypertensive reactions by inputs of deep peroneal nerve].
Our previous work has indicated that excitation of hypothalamic defence area (HDA) could lead to an increase in the release of central monoamine neurotransmitters, pressor and other defence responses. The present experiments showed that stimulation of deep peroneal nerve with a current of low frequency and low intensity could inhibit the pressor, abolish the increase of noradrenaline and its metabolite MHPG and attenuate that of 5-HIAA (a 5-HT metabolite), dopamine and its metabolites DOPAC and HVA in CSF. The data suggest that inputs of deep peroneal nerve may inhibit the increased release of central monoamine neurotransmitters, and then defence reactions; and inhibition of NA release in some nuclei of the brain is an important mechanism of inhibition of defence pressor by inputs of deep peroneal nerve.
