Abstract
The effects of benzalkonium chloride, chlorbutol,xylometazoline and naphazoline on the ciliary beat frequency of human adenoids and chicken embryo tracheas have been determined and compared. Chlorbutol 0.5% appeared to arrest ciliary motion in both tissues within 5 minutes. Rinsing with Locke Ringer solution (LR) restored the ciliary motion almost completely in both cases. Benzalkonium chloride 0.006% +EDTA 0.1% decreased the ciliary beat frequency 35% for the human tissues and 50% for the chicken tissues after a contact of 20 minutes. In both cases the frequency hardly changed after rinsing with LR. Naphazoline nitrate 0.1% and xylometazoline HCl 0.05% have reversible effects on the ciliary beat frequency of both human adenoids and chicken embryo tracheas. Cilia of human adenoids appeared to be more sensitive for xylometazoline than for naphazoline; whereas cilia of chicken embryo tracheas were more affected by naphazoline than by xylometazoline. The results with human adenoids and chicken embryo tracheas show a correlation (correlation coeff. = 0.82, p less than 0.005). In the initial response the differences in sensitivity to preservatives and drugs were in many cases statistically significant, but the final effects were similar.
