Impact of topic administration of nitric oxide donor gel in the clitoridian blood flow, assessed by Doppler ultra-sound.
Summary of "Impact of topic administration of nitric oxide donor gel in the clitoridian blood flow, assessed by Doppler ultra-sound."
This study aims to evaluate of the impact of NO molecules in Pluronic F-127 gel, applied topically in the clitoris, on the clitoridian blood flow of healthy volunteer women, using the Doppler ultra-sound.
A total of 20 healthy women over 18 years old and sexually active with no sexual hormones alteration were enrolled. The Doppler ultra-sound procedure was performed on the artery of the clitoris in patients without the NO donor gel, and then after fifteen minutes of its application the same procedure was done again, to compare the values.
The hemodynamic results showed, that this formulation was responsible for the increase of the systolic and diastolic speeds in about 2,5 times after 15min of the administration of the gel. The initial resistance index was increased in 1.2 due to the local venous congestion in only 15min after the administration of gel. Indicating that this product can be used to promote the dilatation of the artery of the clitoris to treat women with sexual dysfunction.
The use of topic hidrogel as a donor drug in the clitoris of women resulting in a local vasodilatation, without systemic effects. These findings suggest that this preparation may be useful in the management of selected cases of female sexual dysfunction.

Medical and Biotech [MESH] Definitions
A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.
Nitric Oxide Synthase
An NADPH-dependent enzyme that catalyzes the conversion of L-ARGININE and OXYGEN to produce CITRULLINE and NITRIC OXIDE.
Nitric Oxide Donors
A diverse group of agents, with unique chemical structures and biochemical requirements, which generate NITRIC OXIDE. These compounds have been used in the treatment of cardiovascular diseases and the management of acute myocardial infarction, acute and chronic congestive heart failure, and surgical control of blood pressure. (Adv Pharmacol 1995;34:361-81)
Nitric Oxide Synthase Type Iii
A CALCIUM-dependent, constitutively-expressed form of nitric oxide synthase found primarily in ENDOTHELIAL CELLS.
Nitric Oxide Synthase Type I

Nitric oxide (NO) is a modulator of left ventricular hypertrophy (LVH) and myocardial relaxation. The impact of NO availability on development of LVH has never been demonstrated in humans. We tested t...
Periadventitial delivery of the nitric oxide (NO) donor PROLI/NO following arterial injury effectively inhibits neointimal hyperplasia. Given the short half-life of NO release from PROLI/NO, our goal...
We have previously shown that remote ischemic preconditioning (rIPC) by transient limb ischemia leads to the release of a circulating factor(s) that induces potent myocardial protection. Intra-arteria...
Importance of a nitric oxide donor that can act as a spin trap might bring some new therapeutic possibilities regarding the treatment of ischemic diseases by reducing the intensity of free radical pro...
Ischemia-reperfusion leads to increased levels at the blood-brain barrier of the multidrug efflux transporter, P-glycoprotein that provides protection to the brain by limiting access of unwanted subst...
This blinded, placebo-controlled study will administer inhaled nitric oxide to patients undergoing liver transplantation. The purpose of the study is to test if inhaled nitric oxide preven...
The purpose of this pilot study is to evaluate whether administration of nitric oxide (NO)gas by oxygen hood at 20 ppm significantly increases PaO2, as compared to placebo gas (oxygen), wi...
A minimum of 100 patients will be enrolled in the study to demonstrate which diagnostic treatment (oxygen or nitric oxide) is most capable of identifying patients with a reactive pulmonary...
The purpose of this study is to determine whether inhaled nitric oxide is an effective treatment for microcirculatory dysfunction and acute organ system failure in the early stage of sepsi...
The purpose of this study is to look at the long term consequences of prematurity in infants treated with inhaled nitric oxide (iNO) while in the neonatal intensive care unit.
