The modulation of histamine release by histamine and muscarinic acetylcholine receptors was investigated by using the push-pull technique. The anterior hypothalamic area of the conscious, freely moving rat was superfused through the push-pull cannula with CSF or with CSF containing drugs and the release of endogenous histamine was determined in the(More)
To investigate the modulation of histamine release by autoreceptors and heteroreceptors, the rat anterior hypothalamus was superfused through a push-pull cannula with agonists or antagonists of histamine and acetylcholine muscarinic receptors. Superfusion with the H3 receptor agonist (R)-alpha-methylhistamine inhibited, while superfusion with thioperamide(More)
