Label	Id	Description
Anesthesia, Rectal	D000774	[Procedure involving the instillation of an anesthetic into the rectum.]
Anesthesia, Spinal	D000775	[Procedure in which an anesthetic is injected directly into the spinal cord.]
Anesthesiology	D000776	[A specialty concerned with the study of anesthetics and anesthesia.]
Anesthetics	D000777	[Agents that are capable of inducing a total or partial loss of sensation, especially tactile sensation and pain. They may act to induce general ANESTHESIA, in which an unconscious state is achieved, or may act locally to induce numbness or lack of sensation at a targeted site.]
Anesthetics, Dissociative	D000778	[Intravenous anesthetics that induce a state of sedation, immobility, amnesia, and marked analgesia. Subjects may experience a strong feeling of dissociation from the environment. The condition produced is similar to NEUROLEPTANALGESIA, but is brought about by the administration of a single drug. (From Gilman et al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed)]
Anesthetics, Intravenous	D018686	[Ultrashort-acting anesthetics that are used for induction. Loss of consciousness is rapid and induction is pleasant, but there is no muscle relaxation and reflexes frequently are not reduced adequately. Repeated administration results in accumulation and prolongs the recovery time. Since these agents have little if any analgesic activity, they are seldom used alone except in brief minor procedures. (From AMA Drug Evaluations Annual, 1994, p174)]
Anesthetics, Local	D000779	[Drugs that block nerve conduction when applied locally to nerve tissue in appropriate concentrations. They act on any part of the nervous system and on every type of nerve fiber. In contact with a nerve trunk, these anesthetics can cause both sensory and motor paralysis in the innervated area. Their action is completely reversible. (From Gilman AG, et. al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed) Nearly all local anesthetics act by reducing the tendency of voltage-dependent sodium channels to activate., Anesthetic applied on a specific site of body.]
Sensory System Agents	D018689	[Drugs that act on neuronal sensory receptors resulting in an increase, decrease, or modification of afferent nerve activity. (From Smith and Reynard, Textbook of Pharmacology, 1991, p367)]
Anestrus	D000780	[A state of sexual inactivity in female animals exhibiting no ESTROUS CYCLE. Causes of anestrus include pregnancy, presence of offspring, season, stress, and pathology.]
Estrous Cycle	D030762	[The period of cyclic physiological and behavior changes in non-primate female mammals that exhibit ESTRUS. The estrous cycle generally consists of 4 or 5 distinct periods corresponding to the endocrine status (PROESTRUS; ESTRUS; METESTRUS; DIESTRUS; and ANESTRUS).]
Anethole Trithione	D000781	[Choleretic used to allay dry mouth and constipation due to tranquilizers.]
Thiones	D013871	[Sulfur-containing compounds also known as thioketones of general formula R2C=S.]
Aneuploidy	D000782	[The chromosomal constitution of cells which deviate from the normal by the addition or subtraction of CHROMOSOMES, chromosome pairs, or chromosome fragments. In a normally diploid cell (DIPLOIDY) the loss of a chromosome pair is termed nullisomy (symbol: 2N-2), the loss of a single chromosome is MONOSOMY (symbol: 2N-1), the addition of a chromosome pair is tetrasomy (symbol: 2N+2), the addition of a single chromosome is TRISOMY (symbol: 2N+1).]
Ploidies	D011003	[The degree of replication of the chromosome set in the karyotype.]
Aneurysm, Infected	D000785	[Aneurysm due to growth of microorganisms in the arterial wall, or infection arising within preexisting arteriosclerotic aneurysms.]
Anger	D000786	[A strong emotional feeling of displeasure aroused by being interfered with, injured or threatened.]
Angina Pectoris	D000787	[The symptom of paroxysmal pain consequent to MYOCARDIAL ISCHEMIA usually of distinctive character, location and radiation. It is thought to be provoked by a transient stressful situation during which the oxygen requirements of the MYOCARDIUM exceed that supplied by the CORONARY CIRCULATION.]
Myocardial Ischemia	D017202	[A disorder of cardiac function caused by insufficient blood flow to the muscle tissue of the heart. The decreased blood flow may be due to narrowing of the coronary arteries (CORONARY ARTERY DISEASE), to obstruction by a thrombus (CORONARY THROMBOSIS), or less commonly, to diffuse narrowing of arterioles and other small vessels within the heart. Severe interruption of the blood supply to the myocardial tissue may result in necrosis of cardiac muscle (MYOCARDIAL INFARCTION).]
Angina Pectoris, Variant	D000788	[A clinical syndrome characterized by the development of CHEST PAIN at rest with concomitant transient ST segment elevation in the ELECTROCARDIOGRAM, but with preserved exercise capacity.]
Angina, Unstable	D000789	[Precordial pain at rest, which may precede a MYOCARDIAL INFARCTION.]
