cholinergic parasympathomimetic agent |
<pharmacology> A chemical substance that causes the release of choline (acetylcholine) from parasympathetic nerve endings. (15 Jan 1998) |
|---|---|
cholinergic receptors |
Chemical sites in effector cells or at synapses through which acetylcholine exerts its action. (05 Mar 2000) |
cholinergic system |
<physiology> The system of nerve cells that uses acetylcholine as its neurotransmitter, nerve cells in the cholinergic system are damaged in the brains of Alzheimer patients. (15 Jan 1998) |
cholinergic urticaria |
A form of physical or non-allergic urticaria initiated by heat (e.g., hot baths, physical exercise, pyrexia, exposure to sun or to a warm room) or by excitement; the rather distinctive lesions consist of pruritic areas 1 to 2 mm in diameter surrounded by bright red macules. Synonym: heat urticaria. (05 Mar 2000) |
cholinester |
An ester of choline; e.g., acetylcholine. (05 Mar 2000) |
cholinesterase |
<enzyme> An enzyme that breaks down acetylcholine tostop its action. (22 May 1997) |
cholinesterase inhibitor |
<pharmacology> These are substances which which act to inhibit acetylcholinesterase, the enzyme which breaks down acetylcholine and thus enhance and subsequently prevent transmission of nerve impulses from one nerve cell to another or to a muscle. Examples include pyridostigmine, ambenonium and neostigmine. (15 Jan 1998) |
cholinesterase reactivator |
A drug that reacts directly with the alkylphosphorylated enzyme to free the active unit; the drugs used therapeutically to reactivate phosphorylated forms of acetylcholinesterase are oximes, e.g., diacetylmonoxime, monoisonitrosoacetone, 2-pralidoxime. (05 Mar 2000) |
cholinesterase reactivators |
Drugs used to reverse the inactivation of cholinesterase caused by organophosphates or sulfonates. They are an important component of therapy in agricultural, industrial, and military poisonings by organophosphates and sulfonates. (12 Dec 1998) |
cholinesterases |
<enzyme> Chemical name: Acylcholine acylhydrolase Registry number: EC 3.1.1.8 (12 Dec 1998) |
cholinoceptive |
Referring to chemical sites in effector cells with which acetylcholine unites to exert its actions. Compare: adrenoceptive. Origin: acetylcholine + L. Capio, to take (05 Mar 2000) |
cholinolytic |
Preventing the action of acetylcholine. Origin: acetylcholine + G. Lysis, loosening (05 Mar 2000) |
cholinomimetic |
Having an action similar to that of acetylcholine, the substance liberated by cholinergic nerves; term proposed to replace the less accurate term, parasympathomimetic. Compare: adrenomimetic. Origin: acetylcholine + G. Mimetikos, imitating (05 Mar 2000) |
cholinoreactive |
Responding to acetylcholine and related compounds. (05 Mar 2000) |
cholinoreceptors |
See: cholinergic receptors. (05 Mar 2000) |

cholesterol
|
Important lipid found only in animals. Cholesterol is important as cell membrane component, but also serves as a biosynthetic precursor for steroid hormones (eg sex hormones) and the active gall bladder ingredients bile acids (= detergents). The human liver can synthesize all the necessary levels of cholesterol and will reduce its own synthesis if cholesterol is taken in during a meal (only from animal sources). ...
