1. Evaluation of relaxant responses properties of cinnamon essential oil and its major component, cinnamaldehyde on human and rat corpus cavernosum
ABSTRACT Cinnamomum cassia (Cinnamon) is a well-known traditional medicine with therapeutic benefits for centuries. We evaluated the effects of cinnamon essential oil (CEO) and its main component cinnamaldehyde (CA) on human corpus cavernosum (HCC) and rat CC. The essential oil of cinnamon was analyzed for the confirmation of the oil profile. HCC specimens f

2. Activation of locus coeruleus heme oxygenase-carbon monoxide pathway promoted an anxiolytic-like effect in rats
The heme oxygenase-carbon monoxide pathway has been shown to play an important role in many physiological processes and is capable of altering nociception modulation in the nervous system by stimulating soluble guanylate cyclase (sGC). In the central nervous system, the locus coeruleus (LC) is known to be a region that expresses the heme oxygenase enzyme (HO

3. BAY 41-2272 activates host defence against local and disseminated Candida albicans infections
In our previous study, we have found that 5-cyclopropyl-2-[1-(2-fluoro-benzyl)-1H-pyrazolo[3,4-b]pyridine-3-yl]-pyrimidin-4-ylamine (BAY 41-2272), a guanylate cyclase agonist, activates human monocytes and the THP-1 cell line to produce the superoxide anion, increasing in vitro microbicidal activity, suggesting that this drug can be used to modulate immune f

4. Acute stress-induced antinociception is cGMP-dependent but heme oxygenase-independent
Endogenous carbon monoxide (CO), which is produced by the enzyme heme oxygenase (HO), participates as a neuromodulator in physiological processes such as thermoregulation and nociception by stimulating the formation of 3′,5′-cyclic guanosine monophosphate (cGMP). In particular, the acute physical restraint-induced fever of rats can be blocked by inhibiti

5. Desenvolvimento de Novos Metalofármacos Ativadores/Estimuladores da Enzima Guanilato Ciclase Solúvel / Development of Novel Activators metallodrugs / stimulators of soluble guanylate cyclase enzyme
Este trabalho é um esforço no sentido do desenvolvimento autóctone decomplexos coordenados com metais [Fe (II) e RU (II)] modelados a partir de grupos farmacofóricos que estimulam ou ativam a enzima guanilato ciclase solúvel(GCs). Para tanto, utilizou-se modelos in vitro de reatividades vascular (anéis de aorta) e medidas de pressão arterial in vivo p

6. Estudo do efeito relaxante de um novo composto doador de óxido nítrico em preparações de traquéias isoladas de ratos / Study of the relaxing effect of a new nitric oxide donor compound in preparations of isolated rat tracheae
This study evaluated the mechanisms of relaxation of two nitric oxide (NO) donors, ruthenium complex [Ru(terpy)(bdq)NO+]3+ (Terpy) and sodium nitroprusside (SNP) in isolated trachea of rats. The isolated trachea was sectioned into rings and contracted with carbachol in an organ chamber. The relaxing effect of Terpy and SNP was evaluated at increasing concent

7. Estudo do efeito relaxante de um novo composto doador de óxido nítrico em preparações de traquéias isoladas de ratos / Study of the relaxing effect of a new nitric oxide donor compound in preparations of isolated rat tracheae
O presente trabalho avaliou os mecanismos de relaxamento de dois doadores de óxido nítrico (NO), o complexo de rutênio [Ru(terpy)(bdq)NO+]3+ (Terpy) e o nitroprussiato de sódio (NPS) em traquéias isoladas de ratos. A traquéia isolada foi montada em banho para órgãos isolados e contraída com carbacol para estudo do relaxamento. O efeito relaxante do

8. Blockade of the action of nitric oxide in human septic shock increases systemic vascular resistance and has detrimental effects on pulmonary function after a short infusion of methylene blue
To investigate the role of nitric oxide in human sepsis, ten patients with severe septic shock requiring vasoactive drug therapy and mechanical ventilation were enrolled in a prospective, open, non-randomized clinical trial to study the acute effects of methylene blue, an inhibitor of guanylate cyclase. Hemodynamic and metabolic variables were measured befor

9. Antinociception synergy between the peripheral and spinal sites of the heme oxygenase-carbon monoxide pathway
We have shown that the peripheral and spinal cord heme oxygenase (HO)-carbon monoxide (CO)-soluble guanylate cyclase-cGMP pathways play an important role in antinociception in the rat experimental formalin model. Our objective was to determine if there is synergism between peripheral (paw) and spinal HO-CO pathways in nociception. Rats were handled and adapt

10. Avaliação do efeito relaxante do BAY 41-2272 em detrusor isolado de coelhos / Evaluation of relaxant effect of BAY 41-2272 in rabbit isolated detrusor
Overactive bladder (OAB) is a highly prevalent condition that affects millions of people worldwide with a profound effect on quality of life. The bladder overactivity is related to spontaneous contractions of the detrusor smooth muscle causing an increase in the intravesical pressure and consequently stimulation of the micturirion reflex. Evidences suggest t

11. Participação do óxido nítrico na expressão de vasopressina e ocitocina durante sepse polimicrobiana experimental / Involvement of nitric oxide in vasopressin and oxytocin expression during experimental polymicrobial sepsis.
Sepsis induces massive production of inflammatory mediators, such as nitric oxide (NO), and causes cardiovascular, neuroendocrine and body temperature (Tb) alterations. In the late phase of sepsis there is a basal vasopressin (AVP) release despite the persisting hypotension. One reason could be the inhibition of AVP synthesis by the increase in NO production

12. Receptores de membrana para peptídeos natriuréticos em corpos cavernosos humanos: aspectos moleculares e funcionais. / Membrane receptors for natriuretic peptides in human corpus cavernosum: functional and molecular aspects.
Os receptores para peptídeos natriuréticos têm se mostrado alvos potenciais para o tratamento da disfunção erétil masculina, devido ao fato de os agonistas de GC de membrana elevarem os níveis intracelulares de GMPc, promovendo o relaxamento do músculo liso de corpos cavernosos humanos. Dessa forma, investigamos o efeito Peptídeo Natriurético Atria
