Nicorandil is a new coronary and balanced peripheral vasodilating agent that operates through two mechanisms of action: activation of ATP-dependent K-channels and stimulation of guanylate cyclase. A total of 121 patients with symptomatic stable angina pectoris were randomised to receive nicorandil 10 mg twice daily (bd) or amlodipine 5 mg once daily (od) for 8 weeks (optional dosage increase after 2-4 weeks to 20 mg bd and 10 mg od, respec- tively). Symptom-limited exercise tolerance tests were performed at baseline, and after 2 and 8 weeks treatment, respectively. In addition, the number of anginal attacks, nitroglycerin (NTG) usage, blood pressure (BP), heart rate (HR) and adverse events were recorded, and a subjective assessment of quality of life performed.

Toxic & Infectious Substances 7. Radioactive Material 8. Corrosives 9. Miscellaneous Dangerous Goods CLASS 1: EXPLOSIVES Explosives are materials or items which have the ability to rapidly conflagrate or detonate as a consequence of chemical reaction. Subclass Subclass 1.1: Explosives with a mass explosion hazard Consists of explosives that have a mass explosion hazard. A mass explosion is one which affects almost the entire load instantaneously. Subclass 1.2: Explosives with a severe projection hazard Consists of explosives that have a projection hazard but not a mass explosion hazard. Subclass 1.3: Explosives with a fire Consists of explosives that have a fire hazard and either a minor blast hazard or a minor projection hazard or both but not a mass explosion hazard. Subclass 1.4: Minor fire or projection hazard Consists of explosives that present a minor explosion hazard. The explosive effects are largely confined to the package and no projection of fragments of appreciable size or range is to be expected. An external fire must not cause virtually instantaneous explosion of almost the entire contents of the package. Subclass 1.5: An insensitive substance with a mass explosion hazard Consists of very insensitive explosives with a mass explosion hazard (explosion similar to 1.1). This division is comprised of substances which have a mass explosion hazard but are so insensitive that there is very little probability of initiation or of transition from burning to detonation under normal conditions of transport.

  • Nitroglycerin Sublingual Tablets, USP)
    NDA 021134/S-004 Page 4 Nitrostat® (Nitroglycerin Sublingual Tablets, USP) DESCRIPTION Nitrostat is a stabilized sublingual compressed nitroglycerin tablet that contains 0.3 mg , 0.4 mg , or 0.6 mg nitroglycerin; as well as lactose monohydrate, NF; glyceryl monostearate, NF; pregelatinized starch, NF; calcium stearate, NF powder; and silicon dioxide, colloidal, NF. Nitroglycerin, an organic nitrate, is a vasodilating agent. The chemical name for nitroglycerin is 1, 2, 3 propanetriol trinitrate and the chemical structure is: NO2 O O N O CH2CHCH2 O NO 2 2 C3H5N309 Molecular weight: 227.09 CLINICAL PHARMACOLOGY The principal pharmacological action of nitroglycerin is relaxation of vascular smooth muscle. Although venous effects predominate, nitroglycerin produces, in a dose-related manner, dilation of both arterial and venous beds. Dilation of postcapillary vessels, including large veins, promotes peripheral pooling of blood, decreases venous return to the heart, and reduces left ventricular end-diastolic pressure (preload). Nitroglycerin also produces arteriolar relaxation, thereby reducing peripheral vascular resistance and arterial pressure (afterload), and dilates large epicardial coronary arteries; however, the extent to which this latter effect contributes to the relief of exertional angina is unclear. Therapeutic doses of nitroglycerin may reduce systolic, diastolic, and mean arterial blood pressure. Effective coronary perfusion pressure is usually maintained, but can be compromised if blood pressure falls excessively, or increased heart rate decreases diastolic filling time. Elevated central venous and pulmonary capillary wedge pressures, and pulmonary and systemic vascular resistance are also reduced by nitroglycerin therapy. Heart rate is usually slightly increased, presumably due to a compensatory response to the fall in blood pressure.

    DITTMAR V. RIX AND ANOTHER. Circuit Court, S. D. New York. March 13, 1880. PATENT—COMPOUND MADE BY PATENTED PROCESS.—A patent containing two claims, the one for a certain process set forth, and the other for a certain compound made by the process set forth, is not infringed by the manufacture of a similar compound, not made by the patented process. Motion for preliminary injunction to restrain the infringement of letters patent. Everett P. Wheeler and Clarence Lexow, for plaintiff. George Gifford and Causten Browne, for defendants. BLATCHFORD, J. This is a motion for a preliminary injunction to restrain the infringement of letters patent granted to the plaintiff, January 18, 1870, for an “improvement in explosive compounds.” The specification states that the patentee has invented an explosive agent which he calls “Dualin, and which is to be used instead of other explosive agents, such as powder, gun-cotton, nitro-glycerine, dynamite, etc.” It proceeds: “Dualin is a yellowish brown powder, resembling in appearance Virginia smoking tobacco. It will, if lighted in the open air, burn without exploding; but, if confined, it may be made to explode in the same manner as common 343 powder. It is not sensitive to concussion, will not decompose by itself, not cake or pack together, may be readily filled into cartridges, and it matters not whether the place where it is stored be warm or cold, dry or damp. Dualin has from four to ten times the strength of common powder, and is stronger than dynamite, an improvement on nitro-glycerine. Some of the

  • 2,4,6-Trinitrotoluene (Tnt)
    2,4,6-TRINITROTOLUENE (TNT) What is 2,4,6-TRINITROTOLUENE? 2,4,6-trinitrotoluene, also called TNT, is a man-made compound. The odorless, yellow solid is used in explosives. In the United States, TNT is primarily made at military sites. Where can TNT be found and how is it used? TNT is an explosive used by the military in artillery shells, grenades and airborne bombs. TNT may be found in old artillery shells that wash up or are dredged up on beaches. Industries use TNT to make dye and photography chemicals. How can people be exposed to TNT? You could be exposed to TNT through: Breathing vapor or dust containing TNT. This might happen if your work involves TNT. Drinking water polluted with TNT. This could happen if you drink water polluted by a waste site containing TNT. Eating fruits and vegetables grown in soil containing TNT. Touching soil that contacted TNT. You can also touch it if you work with TNT. Eye Contact by touching the eyes with hands contaminated with TNT, or getting TNT-contaminated dust in them. How does TNT work? When you breathe in air or drink water with TNT in it, the chemical enters your body quickly and completely. If TNT touches the skin, the body absorbs it more slowly. Regardless of the type of exposure, TNT is absorbed by the bloodstream and travels to the organs. When it reaches the liver, it breaks down and changes into several different substances. Not all of these substances have been identified, so it is not known if they are harmful.

  • 1 English 467 Professor Anne Fadiman by Submitting This Essay, I
    English 467 Professor Anne Fadiman By submitting this essay, I attest that it is my own work, completed in accordance with University regulations. Paul Gleason Breaking Rock by Paul Gleason Dino pulls a brass plunger, thick as a screwdriver, off his belt and punches a hole in the yellow-tissue-covered stick of dynamite. He then replaces the plunger with a small cylindrical blasting cap. The late October cold makes the Blasting Gelatin stiff, he explains, raising his voice over the sound of shattering rock coming from under Donnie’s drilling machine. If he tried to shove the blasting cap right in, it might break, and if it broke—“all over,” he says, grinning broadly and waving a hand in circles around his face and chest. “Blood and guts all over you.” Together, the blasting cap and dynamite make a charge. The cap connects to an orange “shock tube,” full of a powder that burns at a rate of three miles per second. Several charges linked together make a shot. Dino drops the charge down one of Donnie’s thirteen-foot holes, letting the tube run between his fingers until it goes slack. He picks up the sixteen-foot-tall pole lying on the ground; it has black circles and numbers marking every foot. He steadily lowers it into the hole and taps the dynamite into place. This is the first of eight holes, eight charges that will go off as one shot. Cox Drilling and Blasting, Dino and Donnie’s employer, is one of several companies working at 18 Temple Street, a 200’-by-100’ lot in the middle of downtown Hartford.

  • Chapter 2 EXPLOSIVES
    Chapter 2 EXPLOSIVES This chapter classifies commercial blasting compounds according to their explosive class and type. Initiating devices are listed and described as well. Military explosives are treated separately. The ingredi- ents and more significant properties of each explosive are tabulated and briefly discussed. Data are sum- marized from various handbooks, textbooks, and manufacturers’ technical data sheets. THEORY OF EXPLOSIVES In general, an explosive has four basic characteristics: (1) It is a chemical compound or mixture ignited by heat, shock, impact, friction, or a combination of these conditions; (2) Upon ignition, it decom- poses rapidly in a detonation; (3) There is a rapid release of heat and large quantities of high-pressure gases that expand rapidly with sufficient force to overcome confining forces; and (4) The energy released by the detonation of explosives produces four basic effects; (a) rock fragmentation; (b) rock displacement; (c) ground vibration; and (d) air blast. A general theory of explosives is that the detonation of the explosives charge causes a high-velocity shock wave and a tremendous release of gas. The shock wave cracks and crushes the rock near the explosives and creates thousands of cracks in the rock. These cracks are then filled with the expanding gases. The gases continue to fill and expand the cracks until the gas pressure is too weak to expand the cracks any further, or are vented from the rock. The ingredients in explosives manufactured are classified as: Explosive bases. An explosive base is a solid or a liquid which, upon application or heat or shock, breaks down very rapidly into gaseous products, with an accompanying release of heat energy.
