Asbestos
|
D001194 |
[Asbestos. Fibrous incombustible mineral composed of magnesium and calcium silicates with or without other elements. It is relatively inert chemically and used in thermal insulation and fireproofing. Inhalation of dust causes asbestosis and later lung and gastrointestinal neoplasms.

Asbestos, Amphibole
|
D017636 |
[A class of asbestos that includes silicates of magnesium, iron, calcium, and sodium. The fibers are generally brittle and cannot be spun, but are more resistant to chemicals and heat than ASBESTOS, SERPENTINE. (From Hawley's Condensed Chemical Dictionary, 11th ed)

D017638 |
[A lavender, acid-resistant asbestos.

Asbestos, Serpentine
|
D017632 |
[A type of asbestos that occurs in nature as the dihydrate of magnesium silicate. It exists in two forms: antigorite, a plated variety, and chrysotile, a fibrous variety. The latter makes up 95% of all asbestos products. (From Merck Index, 11th ed, p.893)

Asbestosis
|
D001195 |
[A form of pneumoconiosis caused by inhalation of asbestos fibers which elicit potent inflammatory responses in the parenchyma of the lung. The disease is characterized by interstitial fibrosis of the lung, varying from scattered sites to extensive scarring of the alveolar interstitium.

Ascariasis
|
D001196 |
[Infection by nematodes of the genus ASCARIS. Ingestion of infective eggs causes diarrhea and pneumonitis. Its distribution is more prevalent in areas of poor sanitation and where human feces are used for fertilizer.

Ascaridia
|
D001197 |
[A genus of nematode worms in the superfamily Heterakoidea. A. galli and A. lineata are important intestinal parasites of domestic fowl.

|
Ascaridiasis
|
D001198 |
[Infection with nematodes of the genus ASCARIDIA. This condition usually occurs in fowl, often manifesting diarrhea.

|
Ascaridida
|
D017162 |

D017191 |
[Infections with nematodes of the order ASCARIDIDA.

|
Ascaridoidea
|
D001199 |

Ascaris
|
D001200 |
[A genus of nematodes of the superfamily ASCARIDOIDEA whose species usually inhabit the intestine.

|
Ascaris lumbricoides
|
D017164 |
[A species of parasitic nematode that is the largest found in the human intestine. Its distribution is worldwide, but it is more prevalent in areas of poor sanitation. Human infection with A. lumbricoides is acquired by swallowing fully embryonated eggs from contaminated soil.
] |
|
Ascaris suum
|
D017165 |
[A species of parasitic nematode usually found in domestic pigs and a few other animals. Human infection can also occur, presumably as result of handling pig manure, and can lead to intestinal obstruction.

Ascites
|
D001201 |
[Accumulation or retention of free fluid within the peritoneal cavity.

|
Ascitic Fluid
|
D001202 |

Asclepias
|
D031108 |
[A plant genus of the family ASCLEPIADACEAE. This is the true milkweed; APOCYNUM & EUPHORBIA hirta are rarely called milkweed. Asclepias asthmatica has been changed to TYLOPHORA.

|
Ascomycota
|
D001203 |
[A phylum of fungi which have cross-walls or septa in the mycelium. The perfect state is characterized by the formation of a saclike cell (ascus) containing ascospores. Most pathogenic fungi with a known perfect state belong to this phylum.

Ascophyllum
|
D044646 |
