This article analyzes 126 cases of perinatal and infant autopsy thymus histological changes and duration of the relationship. MATERIALS AND METHODS Materials Totally 101 autopsies and 25 autopsy cases of infants from 8 days to 11 months of perinatal period Ⅰ were collected. 71 males and 55 females. Analysis of thymus weight, 5 cases of age> 7 days of preterm children plus gestational age <40 weeks, according to perinatal statistics.
