Methods In the study,experimental animals were divided into three groups. Thiamazole was used to replicate the model of maternal pregnant hypothyroidism. The infant rats were innate hypothyroidism. T4 substitution group rats were administrated with T4 from postnatal 0 day as well as the same days normal neonatal rats as control. TdT-mediated dUTP nick end labeling was carried out to detect the positive cells of PCD in cortex and hippocampus of postnatal 7,14 and 21 days rats. Immunohistochemical staining technique was employed to detect Bcl-2 and Bax proteins in relevant sections. Experimental data were statistically analysed by One-Way ANOVA, SNK-q test and Spearman rank correlation analysis.
