The pineal hormone melatonin in panic disorder. 1987

I M McIntyre, and T R Norman, and P F Marriott, and G D Burrows

The nocturnal synthesis of the pineal hormone melatonin was examined from 8 p.m. to midnight in 11 patients with panic disorder and eight control subjects. Patient concentrations of melatonin were significantly lower than controls at 10 p.m. (P less than 0.05; Kruskal-Wallis one-way ANOVA) and midnight (P less than 0.01). At 9 p.m. and 11 p.m., patient concentrations were also lower than controls, but were not statistically significantly different (P = 0.09). From these data, it is postulated that some patients with panic disorder exhibit a generalised defect in sensitivity of beta-adrenergic receptors or of sympathetic transmission.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D008550	Melatonin	A biogenic amine that is found in animals and plants. In mammals, melatonin is produced by the PINEAL GLAND. Its secretion increases in darkness and decreases during exposure to light. Melatonin is implicated in the regulation of SLEEP, mood, and REPRODUCTION. Melatonin is also an effective antioxidant.
D009435	Synaptic Transmission	The communication from a NEURON to a target (neuron, muscle, or secretory cell) across a SYNAPSE. In chemical synaptic transmission, the presynaptic neuron releases a NEUROTRANSMITTER that diffuses across the synaptic cleft and binds to specific synaptic receptors, activating them. The activated receptors modulate specific ion channels and/or second-messenger systems in the postsynaptic cell. In electrical synaptic transmission, electrical signals are communicated as an ionic current flow across ELECTRICAL SYNAPSES.
