The effect of montelukast in a model of gouty arthritis induced by sodium monourate crystals.

Non-steroidal anti-inflammatory drugs (NSAIDS) are the first line of therapy in acute gouty arthritis. NSAIDs inhibit the cyclooxygenase pathway, but not the lipooxygenase activity and can have many adverse effects and thus have a limited effect on the control of inflammation in this disease. In this work we studied the effect of montelukast on the cellular inflammatory infiltrate in a model of murine arthritis induced by sodium monourate crystals (SMU), using a subcutaneous air cavity (air pouch) in BALB/c mice.

[Clinical and pathological features in Venezuelan children with IgA nephropathy].

IgA nephropathy (IgAN) is the most common glomerulonephritis in humans worldwide; its prevalence and prognosis vary according with geographical areas. The incidence is higher in adults under 30 years of age and in children, it occurs more frequently in patients between 3 and 10 years. Hematuria is the predominant manifestation at presentation of the disease and 20-40% of the cases progress to terminal chronic renal disease.

[CXCR-4 AND CCR-5 expression in normal term human placenta].

The maternal-fetal interphase has an active Immunitary System (IS) whose mediators -cells, cytokines and chemokines- coordinately act to favour pregnancy normal development. It is not known exactly which of those mediators are present in each placental cellular stratus and what the physiological or potentially pathologic consequences derived from their presence can be. It is known that chemokines recruit cells with regulatory activity towards the deciduous and some of their receptors are coreceptors to infectious agents like HIV, making research of chemokines expression and their receptors in the maternal-fetal interphase of great interest in recent years.
