| erythromycin | <drug> An antibiotic that disrupts bacterial protein synthesis by binding totheir ribosomes and inhibiting translocation. (09 Oct 1997) |
|---|---|
| erythromycin C-12 hydroxylase | <enzyme> Required for the c-12 hydroxylation of the macrolactone ring in erythromycin synthesis; mw 44 kD; from saccharopolyspora erythraea; amino acid sequence given in first source Registry number: EC 1.14.- Synonym: hydroxylase eryk, eryk gene product, cytochrome p-450(eryk) (26 Jun 1999) |
| erythromycin esterase | <enzyme> Hydrolyzes the lactone ring of erythromycin Registry number: EC 3.1.1.- (26 Jun 1999) |
| erythromycin estolate | <chemical> Lauryl sulfate salt of propionic ester of erythromycin. Found to cause jaundice. Essential hepatotoxic property is due to the propionyl ester linkage at the 2' position. Pharmacological action: antibiotics, macrolide. Chemical name: Erythromycin, 2'-propanoate, dodecyl sulfate (salt) (12 Dec 1998) |
| erythromycin ethylsuccinate | <chemical> Erythromycin, 2'-(ethyl butanedioate). An ester of erythromycin having the same antibacterial effect as erythromycin but with better absorption and fewer side effects. Pharmacological action: antibiotics, macrolide. Chemical name: Erythromycin, 2'-(ethyl butanedioate) (12 Dec 1998) |
| erythromycin glucoheptonate | A salt of the macrolide antibiotic, erythromycin. (05 Mar 2000) |
| erythromycin propionate | A salt of the macrolide antibiotic, erythromycin. (05 Mar 2000) |
| erythromycin stearate | A salt of the macrolide antibiotic, erythromycin. (05 Mar 2000) |
| agar-gel reaction | <immunology> The reaction between an antibody and an antigen during an immunology lab procedure where the two are allowed to diffuse toward each other through an agar-gel medium. Lines of precipitation form in the places on the gel where the two react with each other and shows where the reaction has occurred. (09 Oct 1997) |
| agarose gel electrophoresis | <procedure> A type of electrophoresis that uses a matrix of highly purified agar to separate large nucleotides in size. (06 May 1997) |
| aluminum hydroxide gel | A suspension containing Al2O3, mainly in the form of aluminum hydroxide, used as an antacid; a dried form, with the same use, is obtained by drying the product of interaction in aqueous solution of an aluminum salt with ammonium or sodium carbonate. (05 Mar 2000) |
| aluminum phosphate gel | An aqueous suspension of between 4.0 and 5.0% of aluminum phosphate; used as an antacid. (05 Mar 2000) |
| bag-gel implant | An implant composed of a silicone rubber bag containing a silicone gel; used in augmentation mammaplasty. (05 Mar 2000) |
| gel | Jelly like material formed by the coagulation of a colloidal liquid. Many gels have a fibrous matrix and fluid filled interstices: gels are viscoelastic rather than simply viscous and can resist some mechanical stress without deformation. Examples are the gels formed by large molecules such as collagen (and gelatin), agarose, acrylamide and starch. (18 Nov 1997) |
| gel diffusion | Diffusion in a gel, as in the case of gel diffusion precipitin tests in which the immune reactants diffuse in agar. See: immunodiffusion. (05 Mar 2000) |
