Abstract
With the limited but ongoing usage of di-n-butyl phthalate (DBP) as plasticizer, the health effects of both phthalate and its alternatives are far from being understood. Multigenerational effects of phthalates were evaluated in rats upon exposure to DBP, aiming to provide some evidences about its potential in causing developmental teratogenicity. Gestational rats were exposed to DBP (500 mg/kg bw/day) and control groups with olive oil. On the 18th day of gestation, fetuses (F1) isolated from a few dams were subjected to prenatal screening, and the other rats were allowed to litter, and later postnatal screening was made. DBP-toxicated (F1) rats were crossed and reared up to three generations (F2 and F3) by adopting the same experimental design. A considerable decrease in the weight of placenta, low number of corpora lutea and increased resorptions, and pre- and postimplantation loss were observed in F1, F2, and F3 generations. Further, there was a decrease in the number of live births and fetal body weight with high mortality, the developmental indices showed reduction in litter size and sex ratio, and a considerable incidence of skeletal and malformation complex involving face and eye was observed in later generations compared to the first. The pre-weaning indices in neonates showed a considerable delay in physical growth milestones and poor scores in sensory motor development. Alterations noticed in the levels of thyroid profile and testosterone found to have a role in sensory motor, craniofacial development, and eye formation. In brief, results confirm multigenerational and fetotoxic effects of DBP; thereby, findings imply that developing tissues are the targets and endocrine disruption appears to be the underlying mechanism of phthalate action.
