METHODS A prospective cohort study that recorded all medicines prescribed to patien...
Screening of estrogenic activity on dichloro diphenyl trichloroethane (DDT), dichloro diphenyl dichloro ethylene (DDE), dieldrin, heptachlor, aldrin, chlordane, lindane, polybrominated diphenyl ethers (PBDE) and parabens was compared using Organization for Economic Cooperation and Development (OECD) test guideline 455 (TG455). The estrogenic activity of DDT was 58,000-fold (PC50, 1.67 × 10(-6) ...
A selective, specific and stability-indicating gradient reverse phase high-performance liquid chromatographic (HPLC) method was developed for the determination of Ranitidine in presence of its impurities, forced degradation products and placebo substances such as saccharide and parabens. Ultraviolet detection was performed at 230 nm. Separate portions of the drug product and ingredients were ex...
OBJECTIVE 1) Assessment of the frequency of contact sensitization to selected excipients of dermatological topical preparations and cosmetics in patients with chronic eczema. 2) Detection of the sources of sensitization. METHODS 1,927 patients with chronic eczema (mean age 44.3 years, 601 males, 1,326 females) were patch tested with selected excipients. RESULTS The main rates of sensitizati...
Parabens are added to personal care products as antimicrobial preservatives. They have been suggested endocrine disrupting abilities. Prenatal exposure parabens has associated with reproductive endpoints including reduced male anogenital distance (AGD, from anus genitals), which is sensitive prenatal anti-androgenic exposure. To study the associations between maternal paraben concentrations in ...
