xanthine/inflammation

This work is to investigate the levels of human xanthine oxidoreductase (HXOR), its antibodies, and microorganisms in synovial fluid of patients with untreated rheumatoid joint diseases. Synovial fluids were collected from sixty-four patients with rheumatoid joint diseases. Sixty-four age-matched

Birds have a remarkable longevity for their body size despite an increased body temperature, higher metabolic rate, and increased blood glucose concentrations compared to most mammals. As the end-product of purine degradation, uric acid (UA) is generated in the xanthine/hypoxanthine reactions

As nucleotide catabolism increases during tissue injury the appearance of purine metabolites in inflamed synovial fluid might be of value in understanding the joint damage in inflammatory arthritides. In this study, therefore, synovial and plasma concentrations of hypoxanthine, xanthine, and urate

Dry eye syndrome is a common disease associated to eyes inflammation, irritation and tear film instability. The enzymatic complex of xanthine oxidoreductase (XOR) is involved in the generation of reactive oxygen species (ROS) and uric acid that, in the end, can cause reperfusion injuries, irritation

Cudrania tricuspidata is a plant used in folk medicine in Korea for treatment of diseases related to oxidative stress and inflammation. In this study the leaf and shoot extract was studied for its antioxidant, anti-inflammatory, and xanthine oxidase (XO) inhibitory activities. The extract with

OBJECTIVE To evaluate the effect of low molecular weight heparin on plasma xanthine oxidase concentrations and lung inflammatory response during acute pancreatitis. METHODS Randomized, controlled trial. METHODS Experimental laboratory. METHODS Male Wistar rats. METHODS Acute pancreatitis was induced

The pharmacological actions of the new xanthine, isbufylline, were evaluated in several models of airway hyperresponsiveness and airway inflammation in guinea pigs. At a dose (106 mumol kg-1 i.p.) providing complete protection against acetylcholine aerosol-induced dyspnea in the guinea pig,

It has been previously reported that enprofylline (3-propyl xanthine) prevents histamine-mediated edema formation in the guinea pig lung. To further assess the potential anti-inflammatory effects of enprofylline, we infused it intra-arterially into the canine forelimb before and during a local

We designed and prepared the new C60 fullerene hybrids bearing a xanthine moiety as potential double-action anti-inflammatory agents, capable of simultaneous inhibition of LPS-induced NO and TNF-alpha production. The 10 microM of fulleropyrrolidine-xanthine dyad 2a and b were effective in

Inhibition of xanthine oxidoreductase (XOR) has proven beneficial in a plethora of inflammatory disease processes due to a net reduction in pro-inflammatory oxidants and secondary nitrating species. Electrophilic nitrated fatty acid derivatives, such as nitro-oleic acid (OA-NO₂) are also

A gas chromatographic-mass spectrometric (GC-MS) screening procedure for 23 acidic drugs in equine urine is described. With the GC-MS method fifteen anti-inflammatory drugs, five barbiturates and three methyl xanthines can be detected with good sensitivity and selectivity. The method consists of

Adenosine induces bronchial hyperresponsiveness and inflammation in asthmatics through activation of A2B adenosine receptor (A2BAdoR). Selective antagonists have been shown to attenuate airway reactivity and improve inflammatory conditions in pre-clinical studies. Hence, the identification of novel,

Airway inflammation is suggested to play an important role in bronchial asthma. However, there is poor documentation about the effects of reactive oxygens on airway tissues in aspect of airway inflammation. Presently, we investigated whether aerosolized xanthine (X)/xanthine oxidase (XOD) induces

The nucleotide-binding oligomerization domain-like receptor family, pyrin domain-containing 3 (NLRP3) inflammasome mediates caspase-1 activation and IL-1β processing and is implicated in autoinflammatory as well as other chronic inflammatory diseases. Recent studies have demonstrated that xanthine

The inhibitory effect of various anti-inflammatory drugs on the xanthine oxidase derived depolymerization of hyaluronic acid was studied. The depolymerization was assayed by repeated viscosity measurements. By using a low xanthine oxidase activity, the decrease in viscosity with time followed first
