Embryotoxicity study of monomeric 4,4'-methylenediphenyl diisocyanate (MDI) aerosol after inhalation exposure in Wistar rats.
One of the uses of MDI is as an alternative to formaldehyde in the manufacture of furniture, its main route of exposure to humans being by inhalation. There have been no previous studies on the potential prenatal toxic effects of this compound. To close this gap in information, gravid Wistar rats, Crl:(WI)BR, were exposed by whole-body inhalation to clean air (control) and to 1, 3, and 9 mg/m3 ...
متن کاملPrenatal toxicity of inhaled polymeric methylenediphenyl diisocyanate (MDI) aerosols in pregnant wistar rats.
Mated Wistar rats, 25/group, were exposed to polymeric methylenediphenyl diisocyanate (MDI) aerosol of respirable size for 6 h/day, on gestational days (gd) 6 through 15, at 0, 1, 4, and 12 mg/m3. Maternal clinical signs, body weights, and feed and water consumption were measured throughout gestation. At scheduled sacrifice on gd 20, maternal body, gravid uterine, liver, and paired lung weights...

متن کاملDEVELOPMENT OF A PHYSIOLOGICALLY BASED TOXICOKINETIC MODEL FOR HUMAN EXPOSURE RISK ASSESSMENT OF METHYLENE DIPHENYL DIISOCYANATE(MDI)
Introduction: Given the lack of a developed physiologically based toxicokinetic (PBTK) model for human systemic exposure assessment of methylene diisocyanate (MDI) and prediction of its urinary metabolites, this study aims to develop a PBTK model for exposure risk assessment of MDI. Methods and Materials: In this study, to assess the potential exposure to the MDI, a PBTK model was constructed ...
متن کاملPulmonary irritation after inhalation exposure to benzalkonium chloride in rats.
BACKGROUND Benzalkonium chloride (BAC) is a quaternary ammonium compound (QAC) with a C8 to C18 chain length of alkyl groups. Since BAC exerts toxic effects on microorganisms, it has been used as an effective germicide and preservative, mostly in cosmetic industry and medicine. However, the toxic potential of BAC may be hazardous to humans, due to the common use of preparations containing BAC a...
