This study evaluates the effects of gold nanoparticle in endotoxin-induced uveitis rats.Adult male Wistar rats were divided into five groups: saline + saline, lipopolysaccharide (LPS) LPS prednisolone, salt (GS) and (GNP). Two hours after administration, prednisolone acetate 1%, GS, GNP topically applied to both eyes repeated every 6 for 24 hours. After hours, anesthetized aqueous humor was sampled irides removed. Aqueous TNF-α, myeloperoxidase activity determined. Irides oxidative damage...
Abstract Background Nanogold has been investigated in a wide variety of biomedical applications because the anti-inflammatory properties. The purpose this study was to evaluate effects TPU (Therapeutic Pulsed Ultrasound) with gold nanoparticles (GNP) on oxidative stress parameters and expression pro-inflammatory molecules after traumatic muscle injury. Materials methods Animals were divided nine groups: sham (uninjured muscle); injury without treatment; + DMSO; GNP; DMSO TPU; GNP. ROS...
Abstract The bacterial lipopolysaccharide (LPS) is a highly toxic molecule derived from the outer membrane of gram‐negative bacteria. LPS endotoxin affects lungs and used as model acute pulmonary inflammation affecting cellular morphology organ. Previously, gold nanoparticles (GNPs) have been shown to demonstrate anti‐inflammatory antioxidative activity in muscle epithelial injury models. objective this study was investigate effect intraperitoneal treatment using GNPs on inflammatory...
Tendinitis affects a substantial number of people in several occupations involving repetitive work or direct trauma. Iontophoresis is therapeutic alternative used the treatment injury during inflammatory phase. In recent years, gold nanoparticles (GNP) have been studied due to their anti-inflammatory capacity and as an transport proteins.This study evaluates effects iontophoresis using GNPs diclofenac diethylammonium on parameters rats challenged with traumatic tendinitis.Wistar were divided...
This study evaluated the parameters of oxidative stress and energy metabolism after acute long-term administration gold nanoparticles (GNPs, 10 30 nm in diameter) different organs rats. Adult male Wistar rats received a single intraperitoneal injection or repeated injections (once daily for 28 days) saline solution, GNPs-10 GNPs-30. Twenty-four hours last administration, animals were killed, liver, kidney, heart isolated biochemical analysis. We demonstrated that GNPs-30 increased TBARS...
Malathion is an insecticide widely used in agriculture and public health programs that when indiscriminately large amounts can cause environmental pollution risk to human health. However, it possible during the metabolism of malathion, reactive oxygen species be generated, malathion may produce oxidative stress intoxicated rats responsible for alterations DNA molecules related some studies. As a result, present study aimed investigate damage cerebral tissue peripheral blood after acute...
We report the effect of gold nanoparticles (AuNP) in an acute inflammation model induced by carrageenan (CG) and compared this with those antioxidant N-acetylcysteine (NAC) alone synergistic NAC AuNP together. Male Wistar rats received saline or containing CG administered into pleural cavity, some also (20 mg/kg) subcutaneously and/or cavity immediately after surgery. Four hours later, were sacrificed exudates obtained for evaluation cytokine levels myeloperoxidase activities. Oxidative...
AbstractThis article describes the synthesis, liquid crystalline and photophysical properties of luminescent compounds, derived from gallic acid containing heterocyclic 1,3,4-oxadiazole. The mesophases these compounds were characterised using polarising optical microscopy (POM), differential scanning calorimetry (DSC) X-ray diffraction (XRD). All showed high thermal stability blue photoluminescence in solution, with emission maxima between 376 381 nm. For all behaviour was preserved on...
The aim of this study was to evaluate the effects therapeutic pulsed ultrasound with gold nanoparticles on oxidative stress parameters after traumatic muscle injury in Wistar rats. animals were randomly divided into nine groups (n = 6 each): sham (uninjured muscle); without treatment; and treatment dimethyl sulfoxide (15 mg/kg); (27 µg); + (Plus); ultrasound; sulfoxide; nanoparticles; Plus. Gastrocnemius induced by a single-impact blunt trauma. Therapeutic (6-min application, frequency 1.0...
