Mucociliary transport. 1978

M A Sackner

Our laboratory has developed bronchofiberscopic and roentgenographic techniques to measure tracheal, bronchial and nasal mucus velocities in humans and animals. We found that inhalation of specific antigen is associated with depression of tracheal mucus velocity in dogs who may or may not display bronchospasm and the mediator for this phenomenon might be SRS-A. Corroboration of the depression of tracheal mucus transport after ragweed inhalation has been obtained in susceptible asthmatic patients; prior inhalation of cromolyn blocks this reaction. Depression of tracheal mucus transport may be the earliest adverse manifestation of cigarette smoking in young subjects. Slowing of mucus transport in the bronchi occurs after suctioning with suction catheters; a newly designed suction catheter tip, the Aero-Flo, displays less adverse effects on mucus velocity than standard end hold and side hole catheters. Nasal mucus velocity is enhanced by nasal decongestants, ingestion of hot fluids and exercise.

UI	MeSH Term	Description	Entries
D008173	Lung Diseases, Obstructive	Any disorder marked by obstruction of conducting airways of the lung. AIRWAY OBSTRUCTION may be acute, chronic, intermittent, or persistent.

D009093	Mucus	The viscous secretion of mucous membranes. It contains mucin, white blood cells, water, inorganic salts, and exfoliated cells.
D009666	Nose	A part of the upper respiratory tract. It contains the organ of SMELL. The term includes the external nose, the nasal cavity, and the PARANASAL SINUSES.	External Nose,External Noses,Nose, External,Noses,Noses, External
D001980	Bronchi	The larger air passages of the lungs arising from the terminal bifurcation of the TRACHEA. They include the largest two primary bronchi which branch out into secondary bronchi, and tertiary bronchi which extend into BRONCHIOLES and PULMONARY ALVEOLI.

D002923	Cilia	Populations of thin, motile processes found covering the surface of ciliates (CILIOPHORA) or the free surface of the cells making up ciliated EPITHELIUM. Each cilium arises from a basic granule in the superficial layer of CYTOPLASM. The movement of cilia propels ciliates through the liquid in which they live. The movement of cilia on a ciliated epithelium serves to propel a surface layer of mucus or fluid.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001249	Asthma	A form of bronchial disorder with three distinct components: airway hyper-responsiveness (RESPIRATORY HYPERSENSITIVITY), airway INFLAMMATION, and intermittent AIRWAY OBSTRUCTION. It is characterized by spasmodic contraction of airway smooth muscle, WHEEZING, and dyspnea (DYSPNEA, PAROXYSMAL).	Asthma, Bronchial,Bronchial Asthma,Asthmas
