Methanol has been historically considered an exogenous product that leads only to pathological changes in the human body when consumed. However, in normal, healthy individuals, methanol and its short-lived oxidized product, formaldehyde, are naturally occurring compounds whose functions and origins have received limited attention. There are several sources of human physiological methanol. Fruit...
Gasoline engine exhaust has been considered as a major source of air pollution in China. Due to lower cyto- and geno-toxicity effects of methanol engine exhaust, methanol is regarded as a potential substitute for gasoline. We have previously compared cyto- and geno-toxicities of gasoline engine exhaust with that of methanol engine exhaust in A549 cells (Zhang et al., 2007).To characterize the i...
Reanmongkol, W., Subhadhirasakul, S. and Bouking, P. Antinociceptive and antipyretic activities of extracts and fractions from Dracaena loureiri in experimental animals Songklanakarin J. Sci. Technol., 2003, 25(4) : 467-476 Dried coarsely powdered material from the stem woods of Dracaena loureiri Gagnep (D loureiri) has extracted with hexane and methanol to give hexane and methanol extracts, re...
Background Formic acid (formate) is the main reason for toxicity and death through methanol poisoning. The simultaneous determination of methanol, ethanol, and formate in the body can help to discover the cause of death and is useful in the diagnosis of acute methanol poisoning. The measurement of formate is not yet available in Iran. With regard to the increasing rate of methanol poisoning and...
We recently showed that methanol emitted by wounded plants might function as a signaling molecule for plant-to-plant and plant-to-animal communications. In mammals, methanol is considered a poison because the enzyme alcohol dehydrogenase (ADH) converts methanol into toxic formaldehyde. However, the detection of methanol in the blood and exhaled air of healthy volunteers suggests that methanol m...
Methanol is an abundant atmospheric volatile organic compound that is released from both living and decaying plant material. In forest and other aerated soils, methanol can be consumed by methanol-utilizing microorganisms that constitute a known terrestrial sink. However, the environmental factors that drive the biodiversity of such methanol-utilizers have been hardly resolved. Soil-derived iso...
Thermal methanol emission in the DR21 complex Interferometric maps: a comparison with maser emission
We present interferometric observations with∼3.5′′ resolution of the 2k → 1k methanol lines towards the methanol masers in the DR21/DR21(OH) complex. These transitions are not masing and hence our measurements can be used to place limits on the methanol mass associated with the maser spots. We do not find in general good correlation between the peaks of “non-maser” methanol emission and the pos...
A 22-year-old male presented with acute onset vomiting, diarrhea, abdominal pain and altered sensorium. He had a history of acute alcohol intake (locally made with solvent) a day prior to the presentation. Biochemical investigations revealed severe metabolic acidosis. Diagnosis of methanol poisoning was made on the basis of history and biochemical abnormality. Magnetic resonance imaging (MRI) d...
