The aim of the present study was to investigate the effect of the pharmacological blockade of histamine H1 and H2 receptors located within the ventromedial hypothalamus (VMH) on overnight food and water intake and on water intake elicited by two physiological stimuli: hyperosmolarity induced by an acute intragastric salt load and water deprivation. During(More)
The aim of the present study was to evaluate the participation of brain H1 and H2 histaminergic receptors on water and salt intake induced by water deprivation (24 h), furosemide-induced sodium depletion and central angiotensinergic pharmacological stimulation in rats. Third ventricle injections of the H1 and H2 receptor antagonists, mepyramine (50, 100,(More)
In the present study we investigated the participation of central H1 and H2 histaminergic receptors in water intake induced by hyperosmolarity (evoked by intragastric salt load), by hypovolemia (promoted by the subcutaneous administration of polyethyleneglycol) and by the pharmacological stimulation of central cholinergic pathways by the muscarinic agonist(More)
The aim of the present study was to investigate the effect of third ventricle injections of zinc on salt intake in rats in the three different experimental models where sodium appetite is increased: fluid deprivation, central angiotensinergic stimulation and sodium depletion. Adult Wistar male rats received third ventricle injections of Zn(Ac)2 in three(More)
In the present study we investigated, the effect of third ventricle injections of IL-1beta on water and salt intake in fluid-deprived and sodium-depleted rats. Central administration of IL-1beta significantly reduced water and salt intake in fluid-deprived animals and decreased salt intake in sodium-depleted rats. The antidipsogenic and antinatriorexic(More)
