accelerator

 [ak-sel´er-a″ter] (L.)
an agent or apparatus that increases the rate at which something occurs or progresses.
serum prothrombin conversion accelerator (SPCA) factor VII, one of the coagulation factors.

ac·cel·er·a·tor

(ak-sel'er-ā-ter), Avoid the mispronunciation uh-sel'er-ā-ter.
1. Anything that increases rapidity of action or function.
2. In physiology, a nerve, muscle, or substance that quickens movement or response.
3. A catalytic agent used to hasten a chemical reaction. Synonym(s): accelerant
4. In nuclear physics, a device that accelerates charged particles (for example, protons) to high speed to produce nuclear reactions in a target, for the study of subatomic structure, for the production of radionuclides, or for radiation therapy.
[L. accelerans, pres. p. of ac-celero, to hasten, fr. celer, swift]

accelerator

[aksel′ərā′tər]
Etymology: L, accelerare, to quicken
1 a nerve or muscle that increases the rate of performance of some function.
2 an agent or apparatus used to increase the rate at which a substance acts or a function proceeds.

ac·cel·er·a·tor

(ak-sel'ĕr-ā-tŏr)
1. Anything that increases rapidity of action or function.
2. physiology A nerve, muscle, or substance that quickens movement or response.
3. A catalytic agent used to hasten a chemical reaction.
Synonym(s): accelerant.
4. nuclear physics A device that accelerates charged particles (e.g., protons) to high speed to produce nuclear reactions in a target, often for the production of radionuclides or for radiation therapy.

ac·cel·er·a·tor

(ak-sel'ĕr-ā-tŏr) Avoid the mispronunciation uh-sel'er-ā-ter.
1. Anything that increases rapidity of action or function.
2. That which activates developing agents in x-ray film processing chemicals or increases alkalinity, or softens the emulsion in film.
[L. accelerans, pres. p. of ac-celero, to hasten, fr. celer, swift]

accelerator (aksel´ərātur),

n 1. a substance that increases rapidity of action or function.
n 2. a catalyst or other substance that hastens a chemical reaction (e.g., NaCl added to water and plaster to hasten the set).
n 3. a film-developing solution of potassium hydroxide or sodium carbonate used to enlarge the emulsion and to establish an alkaline medium.
accelerator, platelet thrombin,
n See factor, platelet 2.
accelerator, prothrombin conversion, I
n (factor V, labile factor, plasma accelerator globulin, proaccelerin, serum accelerator globulin), a substance that is considered by some to be a factor in serum and plasma that catalyzes the conversion of inactive prothrombin to an active form.
accelerator, prothrombin conversion, II,
n (extrinsic thromboplastin, factor VII, serum prothrombin conversion accelerator [SPCA], stable factor), a substance that is considered by some to be one of the factors in the blood that accelerates the conversion of active prothrombin to thrombin by thromboplastin. Vitamin K deficiency reduces the activity of this factor.
accelerator, serum,
n See factor V.

Patient discussion about accelerator

Q. What herbs are known to be helpful against Arthritis acceleration?

A. mind you- herbs most of the time contain the same medication that pills do but without an exact amount and accompanied with other materials. there is great danger in that area, here is a guide for choosing a herbal supplement that will give you some tips :
