Journal ArticleDOI
Low dopamine‐β‐hydroxylase activity in Down's syndrome
TL;DR: It is reported that patients with Down’s syndrome have a decreased activity of plasma dopamine-0-hydroxylase (DBH), the enzyme that is responsible for forming noradrenaline from dopamine.
Journal ArticleDOI
Catechol-O-methyltransferase activity in erythrocytes in Down's syndrome.
Journal ArticleDOI
Increased N‐Acetylserotonin and Melatonin Formation Induced by d‐Amphetamine in Rat Pineal Gland Organ Culture via a β‐Adrenergic Receptor Mechanism
TL;DR: In cervical ganglionectomized rats the addition of d-amphetamine to the culture medium did not produce an increase in N-acetylserotonin production, and noradrenaline added to the medium gave a high formation of N- acetylser serotonin, which indicates that the major effects ofd-amphetamine on pineal N- Acetyl-transferase activity are mediated by norADrenaline.
Journal ArticleDOI
N-Acetyltransferase and Hydroxyindole-O-Methyltransferase Activity in Intraocular Pineal Transplants: Diurnal Rhythm as Evidence for a Functional Sympathetic Adrenergic Innervation
TL;DR: Immature rat pineal grafts were transplanted bilaterally to the anterior eye chamber of adult male rats and became sympathetically innervated from the host iris and synthesized 5-hydroxytryptamine as revealed by fluorescence histochemistry.
Journal ArticleDOI
Influence of psoralen on melatonin formation in rat pineal gland in organ culture.
TL;DR: The effect of 8-methoxypsoralen is mediated through a postsynaptic event and not by release of noradrenaline or blocked re-uptake of amines to nerve terminals in the pineal gland.
