Allergic reactions to beta-lactam antibiotics have been reported frequently and may occur because of sensitization to unique haptens or to determinants shared with other drugs. A woman who received 1 tablet of amoxicillin-clavulanic acid developed wheals and flares although she had previously tolerated the same preparation well. Levels of specific ...

There is little published experience with the extracorporeal treatment of boric acid overdose, although the pharmacokinetic properties of boric acid suggest a potential role for hemodialysis. We report a rare case of potentially toxic boric acid overdose that was treated successfully with hemodialysis. Based on our experience in this patient ...

Pathogen infection leads to defence induction as well as to changes in carbohydrate metabolism of plants. Salicylic acid and oxylipins are involved in the induction of defence, but it is not known if these signalling molecules also mediate changes in carbohydrate metabolism. In this study, the effect of application of ...

The species of the genus Palicourea (Rubiaceae family) is well-known for its toxicity towards animals, particularly livestock. This work reports the occurrence of skin irritation during the manipulation of Palicourea longiflora, considering the prevalence of the monofluoracetic acid (MFAA) and another toxic compound: methyl salicylate. The MFAA was identified by ...

The generation of OH* radicals inside hydrodynamic cavitation bubbles was monitored using a salicylic acid dosimeter. The reaction of this scavenger with OH* produces 2,5-dihydroxybenzoic acid (2,5-DHB) and, to a lesser degree, 2,3-DHB. The former, is a specific reaction product that can be determined with a very high sensitivity using ...

Recreational abuse or overdose of gamma-hydroxybutyric acid (GHB) results in dose-dependent central nervous system (CNS) effects including death. As GHB undergoes monocarboxylic acid transporter (MCT)-mediated transport across the blood-brain barrier (BBB), one possible strategy for the management of GHB toxicity/overdose involves inhibition of GHB BBB transport. To test this strategy, ...

BACKGROUND: Familial cylindromatosis is a rare genetic disorder, giving rise to neoplasms of the skin appendages. We have recently shown that loss of the cylindromatosis tumour suppressor gene leads to activation of NF-kappaB, a transcription factor having antiapoptotic activity. This provides a possible explanation for the deregulated growth of cylindromas. ...

Paraoxonase 1 (PON 1) is an enzyme that is promiscuous in its ability to hydrolyze various types of substrates. It hydrolyzes aryl esters, phosphate esters, lactones, and reduces lipid peroxides to hydroxides. Aspirin is an aryl ester with a short plasma half life. We hypothesized that aspirin would be effectively ...

Aspirin(acetyl salicylate) has long been used as an analgesic. Salicylic acid has been reported to have anti-inflammatory properties. These activities include inhibiting activity of cox-1, cox-2, and NF-kb. In addition, salicylic acid has also been shown in some systems to induce Hsp70. We have demonstrated that salicylic acid inhibits UVB-induced ...

BACKGROUND: Studies show that pulsed dye laser (PDL) has some clinical benefits on psoriasis with a low clearance rate. In addition, it has been suggested that applying keratolytics before treatment might be helpful in PDL therapy. Topical corticosteroids remain the most commonly prescribed agents for psoriasis. OBJECTIVE: This study was ...

Sudden exposure of plants to high light (HL) leads to metabolic and physiological disruption of the photosynthetic cells. Changes in ROS content, adjustment of photosynthetic processes and the antioxidant pools and, ultimately, gene induction are essential components for a successful acclimation to the new light conditions. The influence of salicylic ...

Tomato plants infected with the citrus exocortis viroid exhibited strongly elevated levels of a compound identified as 2,5-dihydroxybenzoic acid (gentisic acid, GA) 5-O-beta-D-xylopyranoside. The compound accumulated early in leaves expressing mild symptoms from both citrus exocortis viroid-infected tomato, and prunus necrotic ringspot virus-infected cucumber plants, and progressively accumulated concomitant with ...

Arabidopsis leaves treated with simulated acid rain (SiAR) showed phenotypes similar to necrotic lesions caused by biotic stresses like Pseudomonad infiltration. Exposure of Arabidopsis to SiAR resulted in the up-regulation of genes known to be induced by the salicylic acid (SA)-mediated pathogen resistance response. The expression of enhanced disease susceptibility ...

Concentrated sulfuric acid causes severe skin injury. To prevent skin destruction, efficient early treatment is of utmost importance. However, regimens suggested in the literature are not always supported by experimental data. Further studies are needed. To improve early management of sulfuric acid burns, future experiments need careful extrapolation between animal ...

In our previous reports, aspirin, an antipyretic analgesic, suppressed the genotoxicity of mitomycin C (MMC) in a somatic mutation and recombination test (SMART) in Drosophila melanogaster. In order to reveal the mechanism of the anti-genotoxicity of aspirin, we evaluated the suppressing ability of each aspirin metabolite, such as salicylic acid ...
