Résumé
Nitrobenzene is a poisonous agent, not commonly encountered in clinical practice, which belongs to the aniline dyes. Ingestion of nitrobenzene may cause methemoglobinemia, a condition in which the iron in hemoglobin is oxidized from the ferrous state to the ferric state, resulting in the inability to transport oxygen. A 41-year-old man presented with the clinical features of methemoglobinemia after drinking nitrobenzene. The patient was treated conservatively with intravenous methylene blue. We report a case of acute methemoglobinemia due to ingestion of nitrobenzene.

AIM: To determine the effects of phospholipase A 2 (PLA 2) and K ATP on rat ischemia/reperfusion(I/R)-induced arrhythmia. METHODS: Myocardial ischemia and reperfusion were produced by occlusion and reirregation of the left anterior descending artery(LAD). An inhibitor of PLA 2, 5,5-dithio-bis(2-nitrobenzoic acid) (DTNB) (16 mg /kg), a K ATP opener pinacidil (0.2 mg/kg), a K ATP blocker glibenclamide (0.3 mg/kg) was used 5 min prior to 10 min regional ischemia and 10 min reperfusion. RESULTS: DTNB (16 mg/kg) reduced the scores of arrhythmia, creatine kinase (CPK) and lactate dehydrogenase(LDH) (P
