| aluminum silicate | <chemical> The most common mineral of a group of hydrated aluminum silicates, approximately h2al2si2o8-h2o. It is prepared for pharmaceutical and medicinal purposes by levigating with water to remove sand, etc. The name is derived from kao-ling (chinese: "high ridge"), the original site. Pharmacological action: antidiarrhoeals, pharmaceutic aid. Chemical name: Kaolin (12 Dec 1998) |
| magnesium aluminum silicate | An antacid. Synonym: aluminum magnesium silicate. (05 Mar 2000) |
| silicate | <chemistry> A salt of silicic acid. In mineralogical chemistry the silicates include; the unisilicates or orthosilicates, salts of orthosilicic acid; the bisilicates or metasilicates, salts of metasilicic acid; the polysilicates or acid silicates, salts of the polysilicic acids; the basic silicates or subsilicates, in which the equivalent of base is greater than would be required to neutralize the acid; and the hydrous silicates, including the zeolites and many hydrated decomposition products. Origin: Cf. F. Silicate. Source: Websters Dictionary (01 Mar 1998) |
| silicate cement | <chemical> A relatively hard, translucent, restorative material used primarily in anterior teeth. Chemical name: Silicic acid, aluminum calcium salt (12 Dec 1998) |
| silicate restorations | Restoration's of lost tooth structure made with silicate cement. (05 Mar 2000) |
| androgens, synthetic | Compounds obtained by chemical synthesis which possess masculinizing activities, but differ in structure from naturally occurring androgens. (12 Dec 1998) |
| vaccines, synthetic | Small synthetic peptides that mimic surface antigens of pathogens and are immunogenic, or vaccines manufactured with the aid of recombinant DNA techniques. The latter vaccines may also be whole viruses whose nucleic acids have been modified. (12 Dec 1998) |
| genes, synthetic | Biologically functional sequences of DNA chemically synthesised in vitro. (12 Dec 1998) |
| glucocorticoids, synthetic | <chemical> Synthetic chemical compounds which increase gluconeogenesis, raising the concentration of liver glycogen and blood sugar, but differ in structure from naturally occurring glucocorticoids. Pharmacological action: steroidal anti-inflammatory agents, topical anti-inflammatory agents. (12 Dec 1998) |
| resins, synthetic | Polymers of high molecular weight which at some stage are capable of being molded and then harden to form useful components. (12 Dec 1998) |
| mineralocorticoids, synthetic | Synthetic steroids that mimic the activity of the mineralocorticoids obtained from the adrenal cortex, but differ in structure from the naturally occurring mineralocorticoids. (12 Dec 1998) |
| contraceptives, oral, synthetic | Oral contraceptives which owe their effectiveness to synthetic preparations. (12 Dec 1998) |
| contraceptives, postcoital, synthetic | Postcoital contraceptives which owe their effectiveness to synthetic preparations. (12 Dec 1998) |
| progestational hormones, synthetic | Compounds obtained by chemical synthesis that possess progestational activity, but differ in structure from naturally occurring progestational hormones. (12 Dec 1998) |
