[Variations in mucociliary drainage of the nasal fossae after sulfoarsenical thermal therapy].

The saccharine test described by Andersen appears as a simple, harmless and reproducible means to measure the rate of the mucociliary clearance mainly in children. The sweet taste is so strong that the answer is always clear cut. This measured clearance is a good estimate of the efficiency of the first line of defence that builds up the mucus ciliary complex against most of the inhaled noxious agents.
