Postnatal effects of maternal exposure to nitrogen dioxide. 1985

S Tabacova, and B Nikiforov, and L Balabaeva

Pregnant albino rats were exposed to nitrogen dioxide in concentrations of 0.05, 0.10, 1 and 10 mg/m3 for 6 hr each day throughout gestation. Postnatal viability, growth, physical maturation, neuromotor development, and biochemical parameters indicative of NO2 oxidizing effects were studied in progeny up to the age of 3 months. It was found that although viability and physical development were little affected (only at 10 mg/m3), dose-dependent neurobehavioral deviations (such as disturbances in early neuromotor development, coordination deficits, retarded development of locomotion, reduced activity and reactivity) were induced by the lower exposures. The reduction in motor activity was found to persist into the postweaning period.

UI	MeSH Term	Description	Entries
D008099	Liver	A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances.	Livers
D009043	Motor Activity	Body movements of a human or an animal as a behavioral phenomenon.	Activities, Motor,Activity, Motor,Motor Activities
D009585	Nitrogen Dioxide	Nitrogen oxide (NO2). A highly poisonous gas. Exposure produces inflammation of lungs that may only cause slight pain or pass unnoticed, but resulting edema several days later may cause death. (From Merck, 11th ed) It is a major atmospheric pollutant that is able to absorb UV light that does not reach the earth's surface.	Nitrogen Peroxide,Dioxide, Nitrogen,Peroxide, Nitrogen
D011247	Pregnancy	The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.	Gestation,Pregnancies
D011297	Prenatal Exposure Delayed Effects	The consequences of exposing the FETUS in utero to certain factors, such as NUTRITION PHYSIOLOGICAL PHENOMENA; PHYSIOLOGICAL STRESS; DRUGS; RADIATION; and other physical or chemical factors. These consequences are observed later in the offspring after BIRTH.	Delayed Effects, Prenatal Exposure,Late Effects, Prenatal Exposure
D011919	Rats, Inbred Strains	Genetically identical individuals developed from brother and sister matings which have been carried out for twenty or more generations or by parent x offspring matings carried out with certain restrictions. This also includes animals with a long history of closed colony breeding.

D004856	Postural Balance	A POSTURE in which an ideal body mass distribution is achieved. Postural balance provides the body carriage stability and conditions for normal functions in stationary position or in movement, such as sitting, standing, or walking.

D006128	Growth	Gradual increase in the number, the size, and the complexity of cells of an individual. Growth generally results in increase in ORGAN WEIGHT; BODY WEIGHT; and BODY HEIGHT.
