OBJECTIVE We previously demonstrated that among 54 infants in neonatal intensive care units, exposure to polyvinyl chloride plastic medical devices containing the plasticizer di(2-ethylhexyl) phthalate (DEHP) is associated with urinary concentrations of mono(2-ethylhexyl) phthalate (MEHP) , a DEHP metabolite. In this follow-up report, we studied the neonates' exposure to DEHP-containing devices...

A large number of phthalate esters were screened for estrogenic activity using a recombinant yeast screen. a selection of these was also tested for mitogenic effect on estrogen-responsive human breast cancer cells. A small number of the commercially available phthalates tested showed extremely weak estrogenic activity. The relative potencies of these descended in the order butyl benzyl phthalat...

Objective(s) In recent years concerns have been raised regarding the incidence of male reproductive disorders from exposure to endocrine disruptors. So, chronic effects of di(2-ethylhexyl)phthalate were studied on histological and stereological structure of testis in adult Wistar rats. Materials and Methods Thirty two adult Wistar rats were randomly divided in four equal experiment groups; oil ...

The plasticizer di(2-ethylhexyl) phthalate (DEHP) is widely used in building materials. DEHP is identified as the major plasticizer exposure in dwellings. We provide evidence that inhalation exposure to DEHP as aerosols adsorbed to particulate matter is as important, or more important, than vapor phase exposure. The particulate inhalation exposure to DEHP is considered to be significant due to ...

This study evaluated the phytochemical screening, gas chromatography-mass spectrometry (GC-MS) analysis and antioxidant activity of Curcurbitapepo L. using its leaf sample with standard methods. The used for was procured from Imo State University school farm properly identified. Result screening revealed presence saponins, flavonoids, alkaloids, steroids, phlobactannins, proteins, anthraquinnon...

Analysis of the natural abundance C content of dibutyl phthalate (DBP) from two edible brown algae, Undaria pinnatifida and Laminaria japonica, and a green alga, Ulva sp., revealed that the DBP was naturally produced. The natural abundance C content of di-(2-ethylhexyl) phthalate (DEHP) obtained from the same algae was about 50-80% of the standard sample and the C content of the petrochemical (...
