Piroxicam is a non-steroidal anti-inflammatory drug widely used in rheumatic diseases. It has analgesic and antipyretic activity, and is one of the drugs being introduced in clinical practice. Piroxicam-hepatotoxicity has been reported as one of its principal side effects. Several natural antioxidants were found to be effective against drug induced toxicity. Ginger is known by its antioxidant activities and hepatoprotective effects. The present study aimed at studying the protective effect of Ginger on Piroxicam-induced histopathological changes in livers of male mice. ⋯ Piroxicam has toxic effects on the liver as indicated by biochemical, histological and immunohistochemical results. Ginger has protective effects against piroxicam-hepatotoxicity by reducing serum marker enzymes, liver fibrosis and apoptosis.

The efficacy of both quantitative digital subtraction angiography (QDSA) and flat-detector computed tomography perfusion (FD-CTP) is equivalent to that of magnetic resonance perfusion (MRP) in assessing perfusion deficits in carotid stenosis. This study evaluated the feasibility of using FD-CTP to monitor cerebral hemodynamics during carotid stenting. ⋯ FD-CTP provides a potentially more comprehensive hemodynamic assessment of parenchymal perfusion changes compared with QDSA during carotid stenting, but FC-CTP requires additional 18 min. FD-CTP confirmed that the normalization of cerebral hemodynamics began immediately and continued for 1-3 days.
