naphthol AS

01/01/1982 - "A quantitative cytochemical study of isolated hepatocytes from young, middle-aged and old adult rats has shown a doubling of acid naphthol AS-BI phosphatase activity as the hepatocytes shift from the diploid to the tetraploid state, and an overall increase in activity in cells from old animals.

10/01/1983 - "Using this technique the tumor cell membranes were shown to contain esterproteases that reacted with the substrates alpha-naphthyl acetate and naphthol-AS-aminocaproate. "
01/01/1977 - "In solid tumor cells activity of naphthol-AS-acetate esterase is significantly higher than in exudate cells which demonstrate higher activity of PAS reaction. "
05/01/1981 - "Despite the thymic origin of this malignancy, the blast cells contained non-specific esterase activity as determined by naphthol-AS-acetate as substrate. "

01/01/1996 - "(2) Of the four sizable substituted AS naphthol vaccines, naphthol AS-IRG and AS-G vaccines elicited nearly complete defense, but the two other vaccines, inactivated with more elongated molecules, invited rare and successive infections. "
06/01/1973 - "Frozen sections of unfixed or glutaraldehyde-fixed protocorms of Dactylorhiza purpurella infected by Thanatephorus cucumeris (Rhizoctonia solani) were reacted for acid naphthol AS BI phosphatase, acid β-glycerophosphatase or naphthol AS D esterase.A marked increase in particulate acid naphthol AS BI phosphatase activity was observed during infection of host, central, parenchyma cells shortly before hyphae lysed; a diffuse reaction of high activity was localised on lysed fungus.

03/01/1990 - "1 patient with hand dermatitis and positive patch tests to Naphthol AS and nickel was a needlewoman, probably sensitized to Naphthol AS from occupational contact with clothes."
