  • CILIARY DEFECTS ASSOCIATED WITH THE DEVELOPMENT OF BRONCHOPULMONARY DYSPLASIA - CILIARY MOTILITY AND ULTRASTRUCTURE AMERICAN REVIEW OF RESPIRATORY DISEASE Lee, R. M., ROSSMAN, C. M., OBRODOVICH, H., Forrest, J. B., Newhouse, M. T. 1984; 129 (1): 190-193

    Abstract:

    We have on several occasions studied the nasal respiratory epithelium of an infant with hyaline membrane disease that evolved into bronchopulmonary dysplasia and observed an association between the clinical status and naso-ciliary motion and ultrastructure. At 4 months of age, when the patient had significant respiratory disease, few cilia were present and they beat with a slow dyskinetic motion. The specimens contained primarily necrotic and squamous epithelial membranes; the occasional cilia present had swollen or ruptured membranes. Partial recovery of the epithelium was noted at 4.5 months, with 45% of the cilia having normal ultrastructure. The beat frequency was 15.2 +/- 1.5 Hz (mean +/- SD), and although some degree of dyskinesia was evident, primarily normal ciliary motion was observed. By 10 months of age, significant clinical improvement had occurred and the nasal epithelium had regenerated; 96% of the cilia had normal ultrastructure, and the ciliary beat frequency (12.4 +/- 1.2 Hz) and motion were normal.
