| Research Abstract |
It is difficult to evaluate the extent of stress in cases of suspected child abuse/neglect in a medico-legal autopsy. To elucidate the influence upon thymocytes differentiation, we investigated that the morphological change of the thymus and the proportion of the thymocyte subpopulation in abused/neglected children. We found that the relative number of CD4+CD8+ double positive (DP) thymocytes decreased in the abused/neglected children. It was presumed that the selective decrease in the number of the immature DP thymocytes with CD3 ^<- to low> bcl-2^<low> caused the thymic involution in the abused/neglected children. It is proposed that the alteration in the proportion of thymocyte subpopulations could be an index for the degree of the stress in cases of child abuse/neglect.
