| Description: | Aims: The prenatal ethanol exposure induced neuroapoptosis and neuron loss in visual cortex would be investigated in mice at P0, P7 and P14. Methods: Intubating pregnant mice ethanol daily began on E5 and continued through the pups birth. The neuroapoptosis in visual cortex was visualized by the caspase 3 immunocytochemistry, and the neuron loss was observed with Nissl method as well. Results: With prenatal ethanol exposure, the dose-dependent neuroapoptosis and neuron loss in visual cortex could be found at P0 and even at P7 and P14 as well. Conclusions: The prenatal ethanol exposure induced neuroapoptosis and neuron loss will persist into postnatal stage, and the long-term effect of neuroapoptosis might be one of the causes of postnatal neurobehavioural disturbances associated with fetal alcohol syndrome. |
