The Release of Catecholamines from Adrenergic Neurons focuses on the processes involved in determining the release of catecholamines from neurons, noting the influence of alcohols, analgesics, and acids in the release. The selection first discusses biochemical and ultrastructural studies of the mechanism of release, as well as release of constituents of noradrenergic vesicles upon nerve stimulation; constituents of noradrenergic vesicles; and mechanism of release. The book then takes a look at the role of calcium in catecholamine release from adrenergic nerve terminals and presynaptic adrenoceptors and regulation of release. Topics include calcium-dependent versus calcium-independent noradrenaline release; differences between the presynaptic and postsynaptic alpha-adrenoceptors; and influence of neuronal uptake of noradrenaline on the negative feedback mechanism mediated by presynaptic alpha-adrenoceptors. The publication reviews presynaptic muscarine receptors and inhibition of release, including muscarinic inhibition of noradrenaline release evoked by electrical stimulation of sympathetic nerves; effect of muscarinic agonists on noradrenaline releasing procedures independent of calcium ions; and possible physiological and pharmacological significance of the muscarinic inhibitory mechanism. The text also ponders on the role of prostaglandins, cyclic adenosine monophate, analgesics, peptides, acids, anesthetics, and alcohols in the release. The selection is a dependable reference for readers interested in the study of the release of catecholamines from adrenergic neurons.

The Release of Catecholamines from Adrenergic Neurons covers the advances in understanding the mechanism of catecholamine release and other neurotransmitters from adrenergic neurons. This book is organized into four sections encompassing 18 chapters. The opening section surveys biochemical studies of the mechanism and regulation of nerve stimulation. This section examines the role of calcium, prostaglandins, and presynaptic adrenoceptors and muscarine receptors in catecholamine release. The next section describes the modification of catecholamine release by several drugs, including adrenergic neuron blocking agents, narcotic analgesics, opioid peptides, lysergic acid diethylamide, anesthetics, alcohols, and adenosine and adenine nucleotides. These topics are followed by discussions of catecholamine release induced by cations and other drugs, such as nicotinic agonists, calcium ionophores, veratridine, scorption venom, and phenethylamines. The final section deals with the biochemical assessment of peripheral adrenergic activity and the clinical pharmacology of adrenergic neuron blocking agents. This book is intended for pharmacologists, neurologists, researchers, and advanced students.
