Newborn Exposure to Polycyclic Aromatic Hydrocarbons Through Parenteral Nutrition.

Background And Objectives: Parenteral nutrition (PN) administered to newborns (NB) may be contaminated with polycyclic aromatic hydrocarbons (PAHs) and may therefore increase the contact with these toxicants in very early life stages. The aim of the study is to determine to what extent, if any, commercial products for PN are contaminated with PAHs and to determine whether these contaminants, when present in the bag content, are delivered to NB and whether 1-hydroxypyrene (1-HP), the pyrene metabolite, can be detected in the urine of exposed NB.

Methods: Commercial products and the bags administered to 10 NB during their period in the NICU were analyzed for the 16 priority US Environmental Protection Agency PAHs.

Determination of Polycyclic Aromatic Hydrocarbons in Commercial Parenteral Formulations and Medications Using High-Performance Liquid Chromatography with Diode Array Detection.

HPLC coupled to UV diode array detection (DAD) is proposed for the determination of polycyclic aromatic hydrocarbons (PAHs) in pharmaceutical products for parenteral administration. Because rubber is a possible source of PAHs for these products, samples stored in containers with rubber parts were selected for the analysis. The basis for method optimization was EPA Method 8310, which determines 16 priority PAHs in ground water and wastewater by HPLC using both UV and fluorescence detection.

Presence of Polycyclic Aromatic Hydrocarbons in Rubber Packaging Materials and in Parenteral Formulations Stored in Bottles With Rubber Stoppers.

Background: Rubber closures are the primary packaging material for sterile preparations intended for repeated use. Important features of rubber closures are achieved after additives are added to the elastomeric material that compounds the rubber. Among these additives is carbon black.

Effects of Campomanesia xanthocarpa on biochemical, hematological and oxidative stress parameters in hypercholesterolemic patients.

Ethnopharmacological Relevance: In Southern Brazil, the plant Campomanesia xanthocarpa Berg. (Myrtaceae), popularly known as "guavirova", has been empirically used for its potential effect in reducing blood cholesterol levels.

Aim Of The Study: Since there are no scientific data confirming its popular use, the aim of the present study was to investigate the effect of Campomanesia xanthocarpa on biochemical, hematological, anthropometrical and oxidative stress parameters in hypercholesterolemic patients.
