Antibody-Dependent Enhancement
|
D019067 |
[Enhancement of viral infectivity caused by non-neutralizing antibodies. There are at least two mechanisms known to account for this: mediation by Fc receptors (RECEPTORS, FC) or by complement receptors (RECEPTORS, COMPLEMENT). Either the virus is complexed with antiviral IMMUNOGLOBULIN G and binds to Fc receptors, or virus is coated with antiviral IMMUNOGLOBULIN M and binds to complement receptors.

Antibody-Producing Cells
|
D000921 |
[Cells of the lymphoid series that can react with antigen to produce specific cell products called antibodies. Various cell subpopulations, often B-lymphocytes, can be defined, based on the different classes of immunoglobulins that they synthesize.

Anticarcinogenic Agents

Anticestodal Agents
|
D000923 |
[Agents used to treat tapeworm infestations in man or animals.
, Agents used in the treatment of ECHINOCOCCOSIS, especially those that kill the hydatid cyst, or larvae, of ECHINOCOCCUS worms.

Anticholesteremic Agents

Anticholinergic Syndrome
|
D064807 |
[Adverse drug effects associated with CHOLINERGIC ANTAGONISTS. Clinical features include TACHYCARDIA; HYPERTHERMIA; MYDRIASIS, dry skin and dry mucous membranes, decreased bowel sounds and urinary retention in peripheral anticholinergic syndrome; and HALLUCINATIONS; PSYCHOSES; SEIZURES; and COMA in central anticholinergic syndrome.

Anticipation, Genetic
|
D020132 |
[The apparent tendency of certain diseases to appear at earlier AGE OF ONSET and with increasing severity in successive generations. (Rieger et al., Glossary of Genetics: Classical and Molecular, 5th ed)

Anticipation, Psychological
|
D059031 |

Anticodon

D000926 |
[The sequential set of three nucleotides in TRANSFER RNA that interacts with its complement in MESSENGER RNA, the CODON, during translation in the ribosome.

|
Anticonvulsants
|
D000927 |
[Drugs used to prevent SEIZURES or reduce their severity.
] |
|
Antidepressive Agents
|
D000928 |
[Mood-stimulating drugs used primarily in the treatment of affective disorders and related conditions. Several MONOAMINE OXIDASE INHIBITORS are useful as antidepressants apparently as a long-term consequence of their modulation of catecholamine levels. The tricyclic compounds useful as antidepressive agents (ANTIDEPRESSIVE AGENTS, TRICYCLIC) also appear to act through brain catecholamine systems. A third group (ANTIDEPRESSIVE AGENTS, SECOND-GENERATION) is a diverse group of drugs including some that act specifically on serotonergic systems.

|
Antidepressive Agents, Second-Generation
|
D018687 |
[A structurally and mechanistically diverse group of drugs that are not tricyclics or monoamine oxidase inhibitors. The most clinically important appear to act selectively on serotonergic systems, especially by inhibiting serotonin reuptake.
] |
|
Antidepressive Agents, Tricyclic
|
D000929 |
[Substances that contain a fused three-ring moiety and are used in the treatment of depression. These drugs block the uptake of norepinephrine and serotonin into axon terminals and may block some subtypes of serotonin, adrenergic, and histamine receptors. However the mechanism of their antidepressant effects is not clear because the therapeutic effects usually take weeks to develop and may reflect compensatory changes in the central nervous system.

Antidiarrheals
|
D000930 |
[Miscellaneous agents found useful in the symptomatic treatment of diarrhea. They have no effect on the agent(s) that cause diarrhea, but merely alleviate the condition.

|
Antidiuretic Agents
|
D050034 |
[Agents that reduce the excretion of URINE, most notably the octapeptide VASOPRESSINS.

Antidiuretic Hormone Receptor Antagonists
|
D065092 |
[Endogenous compounds and drugs that inhibit or block the activity of ANTIDUIRETIC HORMONE RECEPTORS.

Antidotes
|
D000931 |
[Agents counteracting or neutralizing the action of POISONS.

|
Antiemetics
|
D000932 |
[Drugs used to prevent NAUSEA or VOMITING.
] |
|
Antifibrinolytic Agents
|
D000933 |
[Agents that prevent fibrinolysis or lysis of a blood clot or thrombus. Several endogenous antiplasmins are known. The drugs are used to control massive hemorrhage and in other coagulation disorders.
