The present study investigated the effects of bilateral injections of the nonselective CCK receptor antagonist proglumide or CCK-8 into the lateral parabrachial nuclei (LPBN) on the ingestion of 0.3 M NaCl and water induced by intracerebroventricular injection of ANG II or by a combined treatment with subcutaneous furosemide (Furo) + captopril (Cap). Compared with the injection of saline (vehic...
Interleukin-1β (IL-1β) is involved in mood alterations associated with inflammatory illnesses and with stress. The synaptic basis of IL-1β-induced emotional disturbances is still unknown. To address the possible involvement of the endocannabinoid system in IL-1β-induced anxiety, we performed behavioral and neurophysiological studies in mice exposed to stress or to intracerebroventricular inject...
in the present study, the effect of gaba (γ-aminobutyric acid) receptor agonists and antagonists on morphine-induced antinociception was investigated in formalin test in rats. intraperitoneal (i.p.) injection of different doses of morphine (1, 3, 6 and 9 mg/kg) and intracerebroventricular (i.c.v.) injection of different doses of muscimol (0.5, 1 and 2 g/rat) or baclofen (0.25, 0.5 and 1 g/rat) ...
Steiner, Alexandre A., Eduardo Colombari and Luiz G. S. Branco. Carbon monoxide as a novel mediator of the febrile response in the central nervous system. Am. J. Physiol. 277 (Regulatory Integrative Comp. Physiol. 46): R499–R507, 1999.—Heme oxygenase catalyzes the metabolism of heme to biliverdin, free iron, and carbon monoxide (CO), which has been shown to be an important neuromodulatory agent...
We studied the role of brain kinins in the regulation of cardiovascular function. Intracerebroventricular injection of 380 pmol bradykinin increased mean blood pressure by 20 +/- 2 mm Hg (P < .01) in normotensive Wistar-Kyoto (WKY) rats. Complete inhibition of this effect was achieved with intracerebroventricular administration of the newly synthesized, long-acting B2 receptor antagonist D-Arg,...
Heme oxygenase catalyzes the metabolism of heme to biliverdin, free iron, and carbon monoxide (CO), which has been shown to be an important neuromodulatory agent. Recently, it has been demonstrated that lipopolysaccharide (LPS) can induce the enzyme heme oxygenase in glial cells. Therefore, the present study was designed to test the hypothesis that central CO plays a role in LPS-induced fever. ...
There are critical postnatal periods during which even subtle interventions can have long-lasting effects on adult physiology. We asked whether an immune challenge during early postnatal development can alter neuronal excitability and seizure susceptibility in adults. Postnatal day 14 (P14) male Sprague Dawley rats were injected with the bacterial endotoxin lipopolysaccharide (LPS), and control...
