Abstract:
Objective To examine whether neonate′s cord blood T-lymphocytes is related to infant temperament.Methods Twenty-five healthy babies were randomly chosen in Changsha from Jul.2005 to Aug.2005 and their cord blood was drown when they were born. CD4+ and CD8+ counts, CD4+%, CD8+%, CD4+/ CD8+ratios were obtained using flow cytometry analysis. Infant temperament were measured after 1-4 months( mean age 2.52 months) with parent response to carey revised infant temperament questionnaire(EITQ/RITQ) administered.Results The percentage of CD4+ T-cell subsets to total lymphocytes correlated negatively with persistence scores (r=-0.43 P=0.033). However, CD8+%, CD8+ and CD4+ counts, CD4+/ CD8+ ratios were not correlated with temperament traits.Conclusions The lower CD4 %, the better infants' persistence.
