Baicalein, a flavonoid causes prolonged estrus and suppressed fertility output upon prenatal exposure in female mice

Prenatal Mercuric Chloride Exposure Causes Developmental Deficits in Rat Cortex

Introduction: Environmental pollution with heavy metals such as mercury is a major health problem. Growing studies on the field have shown the deleterious effects of mercury on human and nonhuman nervous system, especially in infants, however the effects of prenatal exposure to mercuricchloride on cortical development are not yet well understood. The aim of this study was to investigate the eff...

Chronic Exposure to Diquat Causes Reproductive Toxicity in Female Mice

Diquat is a bipyridyl herbicide that has been widely used as a model chemical for in vivo studies of oxidative stress due to its generation of superoxide anions, and cytotoxic effects. There is little information regarding the toxic effects of diquat on the female reproductive system, particularly ovarian function. Thus, we investigated the reproductive toxic effects of diquat on female mice. C...

Fertility in mice after prenatal exposure to benzo[a]pyrene and inorganic lead.

Experimental evidence suggests that inorganic lead and benzo[a]pyrene (BaP) suppress the development of primordial oocytes during fetal life. We examined the single and combined effects of prenatal exposure to BaP and moderate doses of lead. The fertility and ovarian morphology of F1 female NMRI mice in four treatment groups (nine mice per group) were investigated: control; lead (F0 given 1 g P...

Effects of lung exposure to carbon nanotubes on female fertility and pregnancy. A study in mice.

We studied the effects of preconceptional exposure to multiwalled carbon nanotubes (MWCNTs): mature, female C57BL/6J mice were intratracheally instilled with 67μg NM-400 MWCNT, and the following day co-housed with mature males, in breeding pairs. Time to delivery of the first litter, litter parameters, maternal inflammation and histopathology of lung and liver were recorded. In male offspring, ...

Prenatal nicotine exposure increases apnoea and attenuates nicotinic potentiation of hypoglossal output in mice

Prenatal morphine exposure reduces pyramidal neurons in CA1, CA2 and CA3 subfields of mice hippocampus

Objective(s):This study was carried out to evaluate the effect of maternal morphine exposure during gestational and lactation period on pyramidal neurons of hippocampus in 18 and 32 day mice offspring. Materials and Methods: Thirty female mice were randomly allocated into cases and controls. In case group, animals received morphinesulfate 10 mg/kg.body weight intraperitoneally during 7 days bef...
