Measurement of histamine metabolites in brain and cerebrospinal fluid provides insights into histaminergic activity

Measurements of the concentrations of histamine's metabolites,tele-methylhistamine (t-MH) andtele-methylimidazoleacetic acid (t-MIAA), in brain have been used to evaluate histamine turnover in brains of animals, ...

Stimulation of 5-HT₃ Receptors Inhibits Release of Endogenous Noradrenaline from Hypothalamus

Exposure to 20 mM KCl elicited a Ca⁺⁺-dependent release of endogenous NA (noradrenaline) from superfused rat hypothalamic slices. Two consecutive exposures, S₁ and S₂, respectively, produced NA release of similar...

Measurement of Histamine Metabolites

Affirming the usefulness of measuring the metabolites is not to deny the usefulness of measuring histamine itself. Its measurement alone has yielded a wealth of information on its role in, and contribution to, sy...

Rostral-caudal concentration gradients of histamine metabolites in human cerebrospinal fluid

The metabolites of histamine,tele-methylhistamine (t-MH) andtele-methylimidazoleacetic acid (t-MIAA), have a large concentration gradient between cisternal and lumbar CSF in the rhesus monkey. The possibility of ...

Diurnal fluctuation in levels of histamine metabolites in cerebrospinal fluid of rhesus monkey

In samples of ventricular cerebrospinal fluid (CSF) that were collected from a conscious, restrained rhesus monkey at intervals of 30–90 min, levels of the histamine metabolites,tele-methylhistamine (t-MH) andtel...

Aspects of histamine metabolism

Progress in learning the role of histamine in physiology and pathology has been impeded by difficulties in accurately measuring histamine and by the deficiencies of methods to measure its metabolites. The avai...

Measurement of tele-methylhistamine and histamine in human cerebrospinal fluid, urine, and plasma

A gas chromatographic-mass spectrometric method described by us to measure tele-methylhistamine (t-MH) in brain was used to measure t-MH in human cerebrospinal fluid (CSF), urine and plasma. The presence of t-...

Tricyclic antidepressant drugs block histamine H₂ receptor in brain

THE observation that cyproheptadine is a competitive antagonist of the histamine H₂ receptor linked to adenylate cyclase in brain¹ suggested that the chemically similar tricyclic antidepressant drugs may also hav...

Presence of Imidazoleacetic Acid Riboside and Ribotide in Rat Tissues

THE products of histamine metabolism in vivo have been catalogued in investigations of the urine^1,2, but relatively little work has been done on metabolites present in tissues. Since excreted metabolites reflect ...
