AbstractAbstract
[en] Lung clearance was studied on a group of subjects over 65 years old and on subjects aged between 30 and 40. A slowing down of material deposited in the bronchial tubes (polydispersed colloidal 198Au particles) was observed in the senile subjects. This phenomenon is apparently related not only to a reduced activity of the vibratile ciliae, in connection with the frequent metaplasia of the bronchial cylindrical epithelium, but also to a quantitative and qualitative change in the mucopolysaccharides forming the mucus secretion

On a etudie la clearance pulmonaire d'un groupe de sujets d'age superieur a 65 ans et de sujets d'un age oscillant entre 30 et 40 ans. On a mis en evidence un ralentissement du materiel depose dans l'arbre bronchique (particules polydispersees de 198Au-colloidal) chez les sujets seniles. Ce ralentissement serait en rapport, non seulement avec une reduction de l'activite des cils vibratils, liee a la metaplasie frequente de l'hepitelium cylindrique bronchique, mais aussi avec une variation quantitative et qualitative des mucopolysaccharides constituant la secretion muqueuseOriginal Title
