We report a case of methanol intoxication, which was not distinguished from ethylene glycol intoxication during treatment. A 65-year-old man was transferred to our emergency department because of drowsiness and remarkable metabolic acidosis. He was intubated because his consciousness disturbance worsened. The diagnosis was suspected as methanol or ethylene glycol intoxication in addition to eth...

BACKGROUND Generalized hypoxic pulmonary vasoconstriction (HPV) occurring during exposure to hypoxia is a detrimental process resulting in an increase in lung vascular resistance. Nebulization of sodium nitrite has been shown to inhibit HPV. The aim of this project was to investigate and compare the effects of nebulization of nitrite and different formulations of acidified sodium nitrite on acu...

In this paper we present a study of the influence of alcohol intoxication on an automatic speaker verification system. It is widely known that alcohol intoxication affects one’s speech in many ways, but it remains to be studied how well a system can recognise a person affected by alcohol intoxication. Using the Alcohol Language Corpus as speech database and a text-independent GMM-UBM speaker ve...

Drug intoxication in children and adolescents is not uncommon in Korea. But the tendency of intoxication is changing with some factors, such as national surveillance system, Naderism and increasing concern among physicians. But the death rate of intoxication among adolescents is increasing in spite of decreasing total death rate of intoxication among children and adolescents. Therefore the phys...

aluminum phosphide (alp) is a solid fumigant which is widely used for a suicide attempt in iran. although neurologic symptoms are commonly reported, cerebrovascular stenosis is rare in alp poisoning. we described ischemic stroke as a delayed complication of alp intoxication. a 30-year-old man was admitted because of sudden onset left side hemiplegia, 11 days after intentional ingestion of three...

AIM To examine the changes in the number of children younger than 18 who were hospitalized due to alcohol intoxication at the Department of Pediatrics, University Hospital of Split, from November 1, 1997 to October 31, 2007. METHODS Data on children hospitalized due to intoxication were retrieved from hospital medical records. Children were classified into 4 age groups: 0-5, 6-9, 10-13, and 1...

Plasma levels of nitrite ions have been used as an index of nitric oxide synthase (NOS) activity in vivo. Recent data suggest that nitrite is a potential intravascular repository for nitric oxide (NO), bioactivated by a nitrite reductase activity of deoxyhemoglobin. The precise levels and compartmentalization of nitrite within blood and erythrocytes have not been determined. Nitrite levels in w...

Staphylococcus carnosus reduces nitrate to ammonia in two steps. (i) Nitrate was taken up and reduced to nitrite, and nitrite was subsequently excreted. (ii) After depletion of nitrate, the accumulated nitrite was imported and reduced to ammonia, which again accumulated in the medium. The localization, energy gain, and induction of the nitrate and nitrite reductases in S. carnosus were characte...

Salivary nitrate from dietary or endogenous sources is reduced to nitrite by oral bacteria. In the acidic stomach, nitrite is further reduced to NO and related compounds, which have potential biological activity. We used an in vivo rat model as a bioassay to test effects of human saliva on gastric mucosal blood flow and mucus thickness. Gastric mucosal blood flow and mucus thickness were measur...

The food additive nitrite (E249, E250) is commonly used in meat curing as a food preservation method. Because of potential negative health effects of nitrite, its use is strictly regulated. In an earlier study we have shown that the calculated intake of nitrite in children can exceed the acceptable daily intake (ADI) when conversion from dietary nitrate to nitrite is included. This study examin...
