| cancer, colon: screening and surveillance | Colon cancer is both preventable and curable. It is preventable by removing precancerous colon polyps. It is curable if early cancer is surgically removed before cancer spread to other parts of the body. Therefore, if screening and surveillance programs were practiced universally, there would be a major reduction in the incidence and mortality of colon cancer. (12 Dec 1998) |

| Gaddum and Schild test | A sensitive method for identification of epinephrine in tissue or other material, based on the fluorescence of epinephrine exposed to ultraviolet light in the presence of alkali and oxygen; sensitivity ranges from 1:50 to 1:100 million. (05 Mar 2000) |
| vaginal creams, foams and jellies | Medicated dosage forms for topical application in the vagina. A cream is a semisolid emulsion containing suspended or dissolved medication; a foam is a dispersion of a gas in a medicated liquid resulting in a light, frothy mass; a jelly is a colloidal semisolid mass of a water soluble medicated material, usually translucent.
