| magnesium sulfate | <chemical> Sulfuric acid magnesium salt (1:1). A small colourless crystal used as an anticonvulsant, a cathartic, and an electrolyte replenisher in the treatment of preeclampsia and eclampsia. It causes direct inhibition of action potential in the myometrial muscle cells. Excitation and contraction are uncoupled, which decreases the frequency and force of contractions. Pharmacological action: anticonvulsants, cathartic, tocolytic agents. Chemical name: Sulfuric acid magnesium salt (1:1) (12 Dec 1998) |

| magnesium trisilicate | 2MgO-3SiO2-nH2O;a compound of magnesium oxide and silicon dioxide with varying proportions of water; occurs in nature as meerschaum, pararepiolite, and repiolite; a gastric antacid. (05 Mar 2000) |
| potassium magnesium aspartate | <chemical> An intra-extracellular electrolyte exchange agent with a variety of effects. Beneficial in cardiac insufficiency, potentiates the effect of cardiac glycosides by reducing their toxicity, has hypocholesteraemic effects and potentiates the effects of calcium in disturbed calcium metabolism. Synonym: panangin; tromcardin. Chemical name: DL-Aspartic acid, monopotassium salt, mixt. With potassium hydrogen (T-4)-bis(DL-aspartato(2-)-N,O1)magnesate(2-) (12 Dec 1998) |
| deficiency, magnesium | Can occur due to inadequate intake or impaired intestinal absorption of magnesium. Low magnesium (hypomagnesaemia) is often associated with low calcium (hypocalcaemia) and potassium (hypokalaemia) levels. Deficiency of magnesium causes increased irritability of the nervous system with tetany (spasms of the hands and feet, muscular twitching and cramps, spasm of the larynx, etc.). According to the National Academy of Sciences, the Recommended Dietary Allowances of magnesium are 420milligrams per day for men and 320 milligrams per day for women. The upperlimit of magnesium as supplements is 350 milligrams daily, in addition to the magnesium from food and water. (12 Dec 1998) |
| effervescent magnesium citrate | Magnesium carbonate, citric acid, sodium bicarbonate, and sugar, moistened with alcohol, passed through a sieve, and dried to a coarse granular powder; used as a laxative. (05 Mar 2000) |
| effervescent magnesium sulfate | Effervescent Epsom salt; magnesium sulfate, sodium bicarbonate, tartaric acid, and citric acid, moistened, passed through a sieve, and dried to a coarse granular powder; a purgative. (05 Mar 2000) |
| tribasic magnesium phosphate | Mg3(PO4)2-5H2O;tertiary magnesium phosphate, it is used as an antacid but it does not produce systemic alkalization; 1 g is equivalent in neutralizing power to about 0.46 g of sodium bicarbonate. (05 Mar 2000) |
| aid to families with dependent children | Financial assistance provided by the government to indigent families with dependent children who meet certain requirements as defined by the social security act, title IV, in the u.s. (12 Dec 1998) |
| androgen-dependent secretory protease | <enzyme> Glycoprotein from dog prostate; hydrolyzes arginine and lysine-containing amide and ester protease substrates Registry number: EC 3.4.99.- Synonym: ads-protease (26 Jun 1999) |
| antibody-dependent cell cytotoxicity | The phenomenon of antibody-mediated target cell destruction by non-sensitised effector cells. The identity of the target cell varies, but it must possess surface IgG whose fc portion is intact. The effector cell is a "killer" cell possessing fc receptors. It may be a lymphocyte lacking conventional b- or T-cell markers, or a monocyte, macrophage, or polynuclear leukocyte, depending on the identity of the target cell. The reaction is complement-independent. (12 Dec 1998) |
| antibody-dependent enhancement | 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 IgG and binds to fc receptors, or virus is coated with antiviral IgM and binds to complement receptors. (12 Dec 1998) |
| aromatic NADH-dependent nitroreductase | <enzyme> See also record for 1-nitroreductase; type I nitroreductase is not inhibited by oxygen Registry number: EC 1.- Synonym: nitrofuran reductase, nitrofurazone reductase, type I nitroreductases, NADH-dependent nitro reductase, nitrofurantoin reductase, p-dinitrobenzene reductase, benznidazole nitroreductase, nifurtimox nitroreductase, oxygen-insensitive NADPH nitroreductase, nitrobenzene nitroreductase (26 Jun 1999) |
| aspartic acid 2-oxoglutarate-dependent dioxygenase | <enzyme> Hydroxylates one aspartic acid residue in the first egf-like unit of factor ix Registry number: EC 1.14.11.- Synonym: aspartate 2-oxoglutarate dioxygenase, asp-2-og-dioxygenase, aspartyl beta-hydroxylase, aspartyl (asparaginyl) beta-hydroxylase (26 Jun 1999) |
| ATP dependent 26S protease | <enzyme> Degrades proteins conjugated to ubiquitin; composed of cf-1,cf-2, and cf-3; cf-2 (also known as 240-kD proteasome inhibitor) is identical to aminolevulinic acid dehydratase Registry number: EC 3.4.99.- Synonym: 26s protease, 26 s proteasome complex, 26s proteasome (26 Jun 1999) |
