Abstract
Osteoarthritis is a progressive joint disease characterized by the activation of different molecular mediators, including proinflammatory cytokines, reactive oxygen species, metalloproteinases and nociceptive mediators. Anacardium occidentale L. is a medicinal plant with anti-oxidative and anti-inflammatory properties. In this study we evaluate the effects of cashew nuts (from Anacardium occidentale L.) oral administration on an experimental model of painful degenerative joint disease. Monosodium iodoacetate (MIA) was intraarticularly injected, and cashew nuts were orally administered three times per week for 21 days, starting the third day after MIA injection. Nociception was evaluated by a Von Frey filament test, and motor function by walking track analysis at 3, 7, 14 and 21 days after osteoarthritis. Histological and biochemical alteration were examined at the end of the experiment. Cashew nuts administration reduced pain-like behavior and showed antioxidant activities, restoring biochemical serum parameters: glutathione (GSH), catalase (CAT) levels, glutathione peroxidase (GPx) activity and lipid peroxidation. Moreover, cashew nuts ameliorated radiographic and histological alteration, resulting in decreased cartilage degradation, pro-inflammatory cytokines and metalloproteinases levels and mast cells recruitment. Our results demonstrated that the oral assumption of cashew nuts counteracts the inflammatory and oxidative process involved in osteoarthritis.

[name] => Electronic Von Frey 5 with embedded camera
[description_short] => As an electronic version of the classical Von Frey Filaments esthesiometer (or aesthesiometer), the latest evolution of Bioseb's Electronic Von Frey instrument for determining the mechanical sensitivity threshold in rodents (rats and mice) is a must-have instrument for your reseach on hyperalgesia and allodynia. By measuring and recording the force at which the animal exhibits a paw withdrawal reflex, pathologies related to sensory response and hyper- or hypo-aesthesia can be studied.
The EVF5 includes an embedded camera inside the stimulator handle and a new, dedicated software revolutionizing the experimental process.
