Reproductive and developmental F1 toxicity following exposure of pubescent F0 male mice to bisphenol A alone and in a combination with X-rays irradiation.

Exposure to environmental toxicants may affect reproduction and development of subsequent generations. This study was aimed at determining the male-mediated F1 effects induced following 8-weeks of subchronic exposure of F0 male mice to bisphenol A (BPA) alone and in a combination with X-rays irradiation (IR) started during their puberty. 4.

The effect of preconceptional exposure of F0 male mice to di(2-ethylhexyl)phthalate on the induction of reproductive toxicity in F2 generation.

The aim of the study was the estimation of the effects of 8 weeks exposure mature and pubescent male mice to DEHP on the prenatal development of the offspring F2 generation. The F1 offspring, of males exposed for whole cycle of spermatogenesis to DEHP (2000 mg/kg bw or 8000 mg/kg bw) and unexposed females, at 8-9 weeks of age were caged males with females from the same group, but from different litter. Eight weeks preconceptional exposure of mature F0 males to 2000 mg/kg bw DEHP induced the significantly higher number of dead fetuses in the F2 offspring; however, the effect on the sperm count and quality of F1 males was not seen.

Three generation study of reproductive and developmental toxicity following exposure of pubescent F0 male mice to di-n-butyl phthalate.

Humans are exposed to phthalates continuously throughout life. The aim of this study was to evaluate the genotoxic effects induced in male mice following 8 weeks of subchronic exposure to di-n-butyl phthalate (DBP) during their puberty and to investigate the possibility of transmission of mutations to subsequent generations via the sperm. Pzh:Sfis outbred male mice aged 4.

Male-mediated F1 effects in mice exposed to bisphenol A, either alone or in combination with X-irradiation.

We investigated the possible transmission of heritable changes via the sperm, following preconceptional exposure of mice to bisphenol A (BPA), either alone or in combination with X-irradiation. Males were exposed for 8 weeks to BPA, X-rays or both agents, and mated to unexposed females. Pre- and postnatal development of the offspring of exposed males was examined.

Comparison of the effects of bisphenol A alone and in a combination with X-irradiation on sperm count and quality in male adult and pubescent mice.

Bisphenol A (BPA) is employed in the manufacturing of epoxy, polyester-styrene, and polycarbonate resins, which are used for the production of baby and water bottles and reusable containers, food and beverage packing, dental fillings and sealants. The study was designed to examine the effects of 8-week exposure (a full cycle of spermatogenesis) to BPA alone and in a combination with X-irradiation on the reproductive organs and germ cells of adult and pubescent male mice. Pzh:Sfis male mice were exposed to BPA (5, 10, and 20 mg/kg) or X-rays (0.

Two generation reproductive and developmental toxicity following subchronic exposure of pubescent male mice to di(2-ethylhexyl)phthalate.

Di-(2-ethylhexyl)phthalate (DEHP) is widely present in the human environment. The study aimed at the investigation of potential genotoxic effects induced by subchronic exposure to DEHP in germ cells of male mice in the first period of puberty, and to check if the transmission of mutation to the next generation via the sperm is possible. 8-weeks exposure to 2,000 mg/kg and 8,000 mg/kg of DEHP diminished sperm count and quality, leading to a reduced percentage of pregnant females mated to exposed males.

Developmental toxicity in mice following paternal exposure to Di-N-butyl-phthalate (DBP).

Objective: The aim of the present study was to investigate the effects of paternal Di-N-butyl-phthalate (DBP) exposure pre- and postnatally on F1 generation offspring, and prenatally on F2 generation offspring.

Methods: Male mice were exposed to either 500 mg/kg or 2 000 mg/kg of DBP for 8 weeks, and mated with non-exposed females. Three-quarters of the females were sacrificed a day prior to parturition, and examined for the number of living and dead implantations, and incidence of gross malformations.

[The effects of di-n-butyl phthalate on the somatic cells of laboratory mice].

Phthalates are widely used as a plasticizers in manufacture of synthetic materials and as solvents in sanitary products, cosmetics and pharmaceutical products. Dibutylphthalate (DBP) is used as a plasticizers and as a textile lubricating agent and as solvent in printing ink. The study aimed the evaluation of the magnitude of DNA damage in liver and bone marrow cells and estimation of dibutyl phthalate (DBP) concentration in peripheral blood following prolonged exposure to DBP.

The effects of di-n-butyl phthalate on the germ cells of laboratory mice.

Phthalate are found in the environmental samples due to their wide use in the industry as plasticizers. Di-n-butylphthalate (DBP) is mainly used in nitrocellulose and polyvinyl acetate products as well as in personal-care products. This study was performed to investigate the influence of exposure to DBP on the quantity and quality (motility, morphology) and DNA damage (induction of micronuclei and DNA strand breaks) of male mice gametes.

[Effects of subchronic exposure of laboratory mice to benzylbutyl phthalate (BBP) on the quantity and quality of male germ cells].

The aim of the study was to investigate the effect of 8-weeks exposure of male mice to benzyl butyl phthalate (BBP) on the sperm count and quality of gametes. Pzh:Sfis male mice exposed per os to 450 mg/kg bw (1/16 LD50) and to 1800 mg/kg bw (1/4 LD50) of BBP in olive oil were used in the study. Control mice were treated with olive oil only.
