title: [The effect of alcohol on c-fos gene expression in rat embryo neuroglial].
abstract: OBJECTIVE
  This paper is aimed to explore the mechanisms of brain development abnormality induced by alcohol.
  
  
  METHODS
  Astrocytes and oligodendrocytes of 19-day rat embryo were exploited and cultured in vitro, and alcohol and its metabolite product (acetaldehyde) were added to DMEMF(12) medium. After different exposure times, c-fos expression of astrocytes and oligodendrocytes was measured by the immunocytochemistry technique.
  
  
  RESULTS
  Changes in c-fos gene expression induced by alcohol and acetaldehyde was time and dose dependent. After 1 hr exposure, alcohol and acetaldehyde affected c-fos gene expression in two kinds of neuralglia. C-fos positive expression reached peak value after 2 hr, but recovered after 72 hr and showed special time phase expression.
  
  
  CONCLUSIONS
  Alcohol and acetaldehyde cause abnormal increase of c-fos gene expression in astrocytes and oligodendrocytes. This abnormal expression may play an important role in abnormal brain development induced by alcohol.
