L'exposé s'attachera à définir les principaux problèmes liés au phénomène de corrosion dans les métaux. On abordera les différents types de corrosion (corrosion aqueuse, corrosion atmosphérique, corrosion sèche et corrosion bactérienne). L'accent sera mis sur les phénomènes électrochimiques de base liés à la corrosion aqueuse. On abordera les réactions d'électrodes et de piles du point de vue thermodynamique (diagramme de Pourbaix) et cinétique. On rappellera les différentes formes de corrosion (généralisée, par piqûres, galvanique, caverneuse, intergranulaire, sélective) ainsi que les problèmes couplés de corrosion érosion et de corrosion sous tension. Certains problèmes spécifiques liés aux assemblages collés seront abordés. L'exposé reprendra les différentes possibilités de lutte contre la corrosion. [less ▲]

Inflammatory Effect of Intratracheal Instillation of Ultrafine Particles in the Rabbit: Role of C-Fiber and Mast Cells

The effects of ultrafine polystyrene carboxylate-modified (fluorospheres) on inflammatory processes are being investigated in rabbit lungs. One milliliter of sterile NaCl (0.9%) containing 4 mg of ultrafine particles (UFP) was intratracheally instilled into anesthetized rabbits. The control animals were only instilled with sterile NaCl (0.9%). Twenty hours after being instilled, the rabbits were killed and their lungs were excised and then tracheally perfused with phosphate-buffered physiological solution (PBS). The lung effluents, collected from small holes made in the pleura, were analyzed for substance P (SP) and histamine content by radioimmunoassay (RIA) methods, after administration of drugs. In addition, in other groups of rabbits, the lung wet/dry (W/D) weight ratio was monitored, as were the cellular and protein contents in bronchoalveolar lavage (BAL). Electron microscopy examination was also performed. In tracheally superfused experiments, UFP induced a significant enhancement of both SP and histamine releases after administration of capsaicin (10(-4) M), to stimulate C-fiber, and carbachol (10(-4) M), a cholinergic agonist. A significant increase in histamine release was also recorded in the UFP-instilled group following the administration of both SP (10(-6) M) plus thiorphan (10(-5) M) and compound 48/80 (C48/80) (10(-3) M) to stimulate mast cells. In addition, the BAL fluid analysis of UFP groups showed an influx of neutrophils and an increase in total protein concentration. An increase in the lung WW/DW ratio was also recorded. Both epithelial and endothelial injuries were observed in the lungs of UFP-instilled rabbits. The pretreatment of rabbits in vivo with a mixture of either SR 140333 and SR 48368, a tachykinin NK(1) and NK(2) receptor antagonist, or a mixture of terfenadine and cimetidine, a histamine H(1) and H(2) receptor antagonist, prevented UFP- induced neutrophil influx and increased total proteins and lung WW/DW ratio. Therefore, it can be concluded that chemicaly inert, electrically charged UFP induce a pulmonary inflammatory process during which the release of SP and histamine from C-fibers and mast cells was enhanced after various stimuli. These latter mediators can also modulate the inflammatory process. [less ▲]

A 75 year old woman was found to have a posterior cerebellar lesion which after surgical removal was shown to be a meningioma. Her postoperative course was complicated by a MRSA meningitis and on day 23 after resection, a polyuria up to 11.7 1/24 h became apparent. The diagnosis of cerebral wasting syndrome (CSWS) was made based on biological and clinical features such as an excessive natriuresis (143 mmol/l) resulting in hyponatremia (130 mmol/l) and an osmolarity higher in urine than in blood. A low central venous pressure and a low wedge pressure confirming a volumic depletion indicated the diagnosis of CSWS. This syndrome has marked similarities with the Inappropriate Secretion of Antidiuretic Hormone Syndrome (SIADH) in terms of biological finding with regards to clinical context and presentation. Without an adequate assessment, a patient with CSWS may be misdiagnosed as SIADH. However recognition is important, as water restriction which is part of SIADH treatment, is detrimental to patients with CSWS and can possibly be lethal. [less ▲]
