When glycerol is treated with a mixture of sulfuric and nitric acid, a yellow oily liquid nitroglycerin is formed. |
|
In the decomposition, four moles of nitroglycerin decompose into approximately 30 moles of carbon dioxide, water, nitrogen, and oxygen. |
|
In that same year, the British patented a combination of 58 percent nitroglycerin, 37 percent guncotton, and 5 percent vaseline. |
|
Vasodilators such as nitroglycerin, alcohol, and carbon dioxide may trigger a headache during a cluster period. |
|
As many non-medical members of the public are aware, nitroglycerin is normally administered by placing a tablet under the tongue of the patient. |
|
Gunpowder reigned supreme until the invention of more powerful substances, notably nitroglycerin and its offshoot, dynamite. |
|
Modern, smokeless propellants date from 1846 when both nitrocellulose and nitroglycerin first emerged from European laboratories. |
|
Since nitroglycerin is moderately volatile and adsorbs to plastic, the sublingual tablets must be stored in tightly closed glass containers. |
|
Nitrostarch explosives, however, do not produce the headaches from skin contact that are characteristic of mixtures containing nitroglycerin. |
|
Sublingual nitroglycerin is used to control acute exacerbations of angina and was used as a marker for patient health status. |
|
This interaction has been reported to occur regardless of whether or not propylene glycol is used as a solvent for the nitroglycerin. |
|
If chest pain continues despite use of aminophylline and nitroglycerin, the possibility of myocardial infarction should be considered. |
|
Consequently, nitroglycerin went largely unnoticed for many years, while the manufacture and use of guncotton, despite several notorious accidents, spread throughout Europe. |
|
The signs and symptoms of nitroglycerin toxicity in these animals were usually circulatory collapse, convulsions and methemoglobinemia. |
|
If 250 mg of aminophylline does not relieve chest pain symptoms within a few minutes, sublingual nitroglycerin may be administered. |
|
Although venous effects predominate, nitroglycerin produces, in a dose-related manner, dilation of both arterial and venous beds. |
|
Patients with known hypersensitivity to nitroglycerin or any of the excipients, or with previous idiosyncratic reaction to organic nitrates. |
|
When i.v. nitroglycerin therapy is initiated, patients should be closely monitored to ensure anticoagulation remains adequate. |
|
Having Lou Dobbs and Rick Kaplan reporting to me at the same time was like holding a canister of nitroglycerin in each hand. |
|
The German U-boats were shooting on the boats, so most of the niter they were trying to import to make nitroglycerin was at the bottom of the ocean. |
|
|
Nitrogen is an important component of common chemical explosives like TNT, nitroglycerin, gunpowder, guncotton, nitrocellulose, picric acid, and ammonium nitrate. |
|
Because it's difficult to grow blood vessels in the laboratory, investigators have struggled to identify the molecules that convert nitroglycerin into nitric oxide. |
|
Thus 40 percent straight dynamite contained 40 percent nitroglycerin and 60 percent dope. |
|
After 1883 the use of nitroglycerin was, with a few unimportant exceptions, restricted to oil-well shooting. |
|
He mixed 40 percent of a lower nitrogen content, more soluble nitrocellulose, and 60 percent of nitroglycerin. |
|
Prolonged exposure to nitroglycerin leads to tolerance and impaired endothelium-dependent vasodilation. |
|
The F. D. A. said that it had not examined the quality of the products it was ordering off the market but that it had recorded problems with other unapproved nitroglycerin products in the past. |
|
By chance, he discovered that nitroglycerin was absorbed to dryness by kieselguhr, a porous siliceous earth, and the resulting mixture was much safer to use and easier to handle than nitroglycerin alone. |
|
In 1867, Nobel accidentally discovered that when nitroglycerin dripped on kieselguhr, a silicon-containing earth, it formed a paste that was stable and safer to use than liquid nitroglycerin alone. |
|
Hand lotion contains glycerin, more useful in nitroglycerin. |
|
Likewise, when nitroglycerin therapy is stopped, a decrease in heparin dosage may be necessary and patients should be monitored for signs of excessive anticoagulation. |
|
Each metered dose contains 0.4 mg nitroglycerin. |
|
He was not taking nitroglycerin, and his outcome is unknown. |
|
Paint, varnish, lubricating oil, leather dressings, furniture polish, insecticides, and nitroglycerin are made from peanut oil. |
|
Dynamite or nitroglycerin detonations were used to increase oil and natural gas production from petroleum bearing formations. |
|
It was employed in Pennsylvania, New York, Kentucky, and West Virginia using liquid and also, later, solidified nitroglycerin. |
|
Many early mines were fragile and dangerous to handle, as they contained glass containers filled with nitroglycerin or mechanical devices that activated a blast upon tipping. |
|
Some antihypertensive drugs can cause headache, especially nitric oxide donors including amyl nitrate, isosorbide, nitroglycerin, and sodium nitroprusside. |
|
In the US, drugs such as Isosorbide dinitarte, ergoloid delivered sublingually have been discontinued and nitroglycerin has been replaced with sublingual metered spray. |
|
Nitroglycerin reduces BP by reducing preload and cardiac output, undesirable effects in patients with compromised cerebral and renal perfusion. |
|
|
Nitroglycerin can also be used in conjunction with gun cotton or nitrocellulose as a propellant in military applications. |
|
Nitroglycerin causes relaxation of vascular smooth muscle in both arteries and veins, although the effect on veins predominates at low doses. |
|
Nitroglycerin is an explosive because no outside source of oxygen is needed for its complete combustion. |
|
Nitroglycerin may be administered via several routes, including sublingual, buccal, oral, transdermal, and intravenous. |
