Abstract
Cyclooxygenase inhibitors (CI) which contained risks to fetal health were one of the most effective tocolytics. In order to indirectly investigate the effects of CI in human ductus arteriosus, immunohistochemical staining for cyclooxygenase-1 (COX1) and cyclooxygenase-2 (COX2) was evaluated in post-mortem fetuses with gestational ages between 24 and 34 weeks. Neither COX1 nor COX2 staining was related to gestational age. COX1 and COX2 staining in the vessel walls were not related to each other. COX1 staining in the endothelium, inner media and outer media were positively correlated with each other (COX1 endothelium vs IM staining Spearman's rho statistic [rs] = 0.721, p = 0.001; COX1 endothelium vs OM staining [rs] = 0.634, p = 0.004; COX1 IM vs OM staining [rs] = 0.931, p = 0.001). COX2 staining of endothelium was not correlated with either IM or OM staining. In conclusion, COX2 staining in the post-mortem specimens of human ductus arteriosus between 24 and 34 weeks is weak and limited to the endothelium.
