Nitrous oxide Cocaine

Contrast-enhanced MRI with Gd-DTPA has been applied to the evaluation of several compounds in man, some focusing on the hemodynamic effects of the drugs on cerebral blood volumes. Kolbtisch and others compared the anesthetic agents nitrous oxide and sevofhirane, noting them to produce compound-specific patterns of diffuse increases in cerebral blood volume (Kolbitsch et al., 2001). Intravenous cocaine, on the other hand, was observed to produce dose-dependent vasoconstriction of cerebral blood vessels (Kaufman et ul., 1998).

Samples of lung are useful where the method of administration of the drug is by inhalation. This is true whether it is a gas such as nitrous oxide, a volatile material such as a solvent (e.g. toluene), or a powder (e.g. cocaine). 

Owing to the ready availability of narcotine its effects on the animal organism have been studied extensively, but the observations have not indicated any extensive use in medicine. It is effective neither as a prophylactic nor as a curative in malaria (240). It has only a mild narcotic action (241, 242, 243), and as an analgesic it is much weaker than morphine (244, 245), although it has been recorded that it potentiates the activity of morphine four- to sevenfold (246). The cramps due to the action of cocaine are also augmented by the simultaneous use of narcotine. It does not lower the basal metabolic rate appreciably (247), nor does it shorten the induction period in nitrous oxide narcosis (248). Its effect on respiration is one of acceleration (249, 250), and its effect on smooth muscle of the intestine (251-254), of the bladder (255), of the gall bladder (251, 252, 256, 257), and of the uterus (251, 252, 258-261) is depressive, while the amplitude of the peristaltic pulses is increased (262-265). 

LAPIS INFERNALIS (7761-88-8) A powerful oxidizer. Forms friction- and shock-sensitive compounds with many materials, including acetylene, anhydrous ammonia (produces compounds that are explosive when dry), 1,3-butadiyne, buten-3-yne, calcium carbide, dicopper acetylide. Contact with hydrogen peroxide causes violent decomposition to oxygen gas. Violent reaction with chlorine trifluoride, metal powders, nitrous acid, phosphonium iodide, red or yellow phosphorus, sulfur. Incompatible with acetylides, acrylonitrile, alcohols, alkalis, ammonium hydroxide, arsenic, arsenites, bromides, carbonates, carbon materials, chlorides, chlorosulfonic acid, cocaine chloride, hypophosphites, iodides, iodoform, magnesium, methyl acetylene, phosphates, phosphine, salts of antimony or iron, sodium salicylate, tannic acid, tartrates, thiocyanates. Attacks chemically active metals and some plastics, rubber, and coatings.
