title: [Influence of mode and time of delivery on leukocyte subpopulations in umbilical cord blood].
abstract: METHODS
  The aim of this article was to study the differences between lymphocyte subsets of cord blood newborns according to the mode of delivery.
  
  
  METHODS
  Lymphocytes of 15 infants born by vaginal route and 14 infants born by caesarean section were immunophenotyping by flow cytometer.
  
  
  RESULTS
  Significant higher percentage of CD8+ was found in group of vaginal delivery. We also found high coefficient of linear regression between birthweight and CD23+, CD19+, CD4+/CD25+, NK, CD8+, CD4+, CD+3.
  
  
  CONCLUSIONS
  No effect of operative delivery on percentage and absolute sizes of cord blood lymphocytes subsets except significant higher percentage of CD8+ were found.
