Single palatal processes or homotypic paired palatal processes from 12-day mouse embryos (strain C57Bl) were grown in organ culture on Millipore filters. The epithelium along the medial edge of each palatal process became disrupted, and, by 72 hours of culture, paired palatal processes achieved mesenchymal fusion at the site of disruption. The nasal epithelium of paired palatal processes became...

Cytologic observation was made of the smears from the epipharyngeal mucosa in 160 cases of epipharyngitis, with some reference to the relationship of its results with the clinical symptom. The findings obtained are as follows. 1) The exfoliation of ciliated epithelial cells was of a much higher degree as compared with the normal cases. 2) A fairy good parallel relationship was found between the...

The epithelium lining the mouse larynx occupied the transitional zone between the keratinized stratified squamous epithelium lining the oral cavity and the ciliated columnar one continuing to the trachea. The epithelium showed gradations ranging from stratified squamous through stratified cuboidal to ciliated stratified low-columnar type. It is suggested that the epithelium is identical with th...

BACKGROUND Haemophilus influenzae infection of the nasal epithelium has long been associated with observations of decreased nasal ciliary beat frequency (CBF) and injury to the ciliated epithelium. Previously, we have reported that several agents that slow CBF also have the effect of activating protein kinase C epsilon (PKCε) activity in bronchial epithelial cells. The subsequent auto-downregul...

Protozoa are eukaryotic cells distributed worldwide in nature and are receiving increasing attention as reservoirs and potential vectors for the transmission of pathogenic bacteria. In the environment, on the other hand, many genera of the protozoa are human and animal pathogens. Only limited information is available on these organisms in developing countries and so far no information on their ...
