ethylene

 [eth´ĭ-lēn]
a colorless, highly flammable gas with a slightly sweet taste and odor, used as an inhalation anesthetic to induce general anesthesia.
ethylene glycol a solvent with a sweet, acrid taste, used as an antifreeze. Acute poisoning by ingestion can result in central nervous system depression, vomiting, hypotension, coma, convulsions, renal damage, and death. While damage is thought to be due to the formed oxalic acid, ethanol is a good treatment because it competitively inhibits alcohol dehydrogenase. The unaltered ethylene glycol is then excreted in the urine.
ethylene oxide a gaseous, flammable alkylating agent with a broad spectrum of activity, capable of killing both spores and viruses; it must be mixed with CO2 or fluorocarbons because it is explosive above 3 per cent. It is used in hospitals, surgery, dentistry, and the pharmaceutical and other industries for disinfecting and sterilizing instruments and equipment that would be destroyed by heat or would be adversely affected by immersion in water or other media. Its optimal germicidal effect occurs after a 3-hour exposure at 30°C.ƒ

Ethylene oxide is toxic because it alkylates tissue constituents; it is carcinogenic and may produce adverse reproductive effects. Inhalation may cause nausea, vomiting, and neurological disorders, and severe exposure may be fatal. Before items exposed to ethylene oxide can be used they must be aired for 5 days at room temperature or for 8 hours at 120° C to remove any trace of the gas. This is also true for articles of clothing, such as gloves and shoes, that have been exposed, because chemical burns can occur when the contaminated clothing comes in contact with the skin.

eth·yl·ene

(eth'il-ēn),
An explosive constituent of ordinary illuminating gas; hastens ripening of fruit.

ethylene

/eth·y·lene/ (eth´ĭ-lēn) a colorless flammable gas, CH2dbondCH2, with a slightly sweet odor and taste; formerly used as an inhalation anesthetic.
ethylene dibromide  a fumigant and gasoline additive; it is a skin and mucous membrane irritant and is carcinogenic.
ethylene dichloride  a solvent, gasoline additive, and intermediate; it is irritating and toxic, and can be carcinogenic.
ethylene glycol  a solvent used as an antifreeze; ingestion can cause central nervous system depression, vomiting, hypotension, coma, convulsions, and death.
ethylene oxide  a gas used in manufacturing organic compounds and as a fumigant, fungicide, and sterilizing agent; it is highly irritating to the eyes and mucous membranes and is carcinogenic.

ethylene

(ĕth′ə-lēn′)
n.
A colorless flammable gas, C2H4, derived from natural gas and petroleum and also occurring as a natural plant hormone, used as a source of many organic compounds, in welding and cutting metals, to ripen citrus fruits, and as an anesthetic. Also called ethene.

eth′yl·e′nic (-ə-lē′nĭk, -lĕn′ĭk) adj.

ethylene

[eth′əlēn]
Etymology: Gk, aither, air, hyle, stuff
a colorless flammable gas that is just lighter than air and has a slightly sweet odor and taste. It was previously used as an inhaled general anesthetic and is slightly more potent than nitrous oxide. It is now used in the food industry for control of fruit ripening, flower opening, and the shedding of leaves. Also called ethene, olefiant gas.

ethylene

or

ethene

a simple hydrocarbon with the formula CH2=CH2 that can act as a PLANT HORMONE even when present in very low concentrations (down to 1 ppm). Ethylene inhibits elongation in most growing tissues and promotes leaf ABSCISSION and fruit ripening in some plants. Plant cells produce ethylene from the amino acid METHIONINE. A ripe banana or tomato in a bowl of unripe ones will speed up the ripening process by giving off ethylene.

eth·yl·ene

(eth'il-ēn)
An explosive constituent of ordinary illuminating gas.

ethylene (eth´ilēn),

n (olefiant gas, CH2CH2) a colorless gas of slightly sweet odor and taste; used as an inhalation anesthetic.
ethylene oxide sterilization,
n a process that uses gas to sterilize instruments, equipment, and materials that would otherwise be damaged by heat or liquid chemicals. Effective at room temperature. Requires between 10 and 16 hours to be effective. Gas must penetrate the material. The gas is highly toxic and must be vented before opening the sealed sterilizing unit. Sterilized materials must also be well aerated before using.
etidocaine HCl (local),
n brand names: Duranest, Duranest MPF;
drug class: amide, local anesthetic;
action: inhibits ion fluxes across membranes, particularly sodium transport across cell membrane; decreases rise of depolarization phase of action potential; blocks nerve action potential;
uses: local dental anesthetic, peripheral nerve block, caudal anesthetic, central neural block, vaginal block.

ethylene

a colorless, highly flammable gas with a slightly sweet taste and odor, used as an inhalation anesthetic to induce general anesthesia.

ethylene dibromide (EDB)
grain fumigant. Treated seed seriously reduces egg production when fed to hens in very small amounts.
ethylene dichloride
industrial fumigant; causes respiratory and ophthalmic irritation, narcosis, disturbance of equilibrium.
ethylene glycol
antifreeze; palatable enough for animals to drink in quantity. Causes ataxia, depression, coma, polydipsia, vomiting and convulsions due to formation of oxalate crystals in brain blood vessels and renal tubules.
ethylene oxide
a fumigant used for foodstuffs, surgical equipment and as an agricultural fungicide. It is a gaseous, flammable alkylating agent with a broad spectrum of activity, being sporicidal and viricidal. It is used (mixed with CO2 or fluorocarbons because it is explosive above 3%) for disinfecting and sterilizing equipment and instruments that are used in the hospital, surgery, dentistry, and the pharmaceutical and other industries, and that are thermolabile or will be adversely affected by immersion in water or other media. Its optimal germicidal effect occurs after a 3-hour exposure at 86°F (30°C). Its vapor is irritating to eyes and respiratory mucosa and can cause serious pulmonary edema. Called also oxirane.
