muco-, muc-, muci-, mucin- +

(Latin: mucus, mucous, or mucosa; a viscid, slippery, slime secretion of the mucous membranes; related to mucor, "mold, moldiness")

cystic fibrosis, CF; mucoviscidosis; fibrocystic disease of the pancreas
One of the most common hazardous genetic (inherited) diseases, cystic fibrosis affects the exocrine glands and is characterized by the production of abnormal secretions, leading to abnormally viscous mucus build-up.

This accumulation of mucus can impair the pancreas and, secondarily, the intestine. Mucous build-up in lungs tends progressively to impair respiration.

Without treatment, CF results in death for 95% of affected children before the age of five.

mucid
Musty; moldy; slimy; mucous.
muciferous
Containing or secreting mucus.
mucification
A change produced in the vaginal mucosa of spayed experimental animals following stimulation with estrogen; characterized by the formation of tall columnar cells secreting mucus.
muciform
Appearing similar to mucus.
mucigen
A substance present in mucous cells that, upon being extruded from the cell, is converted into mucin.
mucigenous
Muciparous or producing or secreting mucus.
mucigogue
1. An agent that stimulates the secretion of mucus.
2. Provoking the secretion of mucus.
mucihematein
A staining solution that is based on hematein (a red-brown compound used to stain samples for microscope study), the oxidized form of hematoxylin (a dye used to stain microscope slides for study), and is used to demonstrate the presence of the connective tissue mucin.
mucilage
1. A thick, viscid, adhesive liquid, containing gum or mucilaginous principles dissolved in water, usually employed to suspend insoluble substances in aqueous liquids or as a demulcent.
2. An aqueous solution of a gum utilized for suspending rather insoluble substances in mixtures.

Another use is to increase the viscosity of oil-in-water emulsions; such as, those used for dermatologic preparations and lubricating medications.

mucilaginous
1. Moist and sticky like glue.
2. Having the properties of glue.
3. Resembling mucilage; moist, soft, and viscid; slimy; ropy; such as, a mucilaginous liquid.
4. Referring to, or secreting, mucilage; as, the mucilaginous glands.
5. Soluble in water, but not in alcohol; yielding mucilage; as, mucilaginous gums or plants.
mucilloid
1. A mucilaginous preparation.
2. A thick, sticky, glue-like preparation resembling mucilage.
mucin
1. A complex protein present in mucus.
2. Any of a group of glycoproteins found especially in the secretions of mucous membranes.
3. Any mucoprotein secreted by cells which raises the viscosity of the medium around them.
4. A class of glycoproteins found in saliva, gastric juice, etc., that form viscous solutions and act as lubricants or protectants on external and internal surfaces of the body.

Mucin has the following characteristics: it is viscid, clear and tenacious; when dissolved in water it can be precipitated by the addition of acetic acid; and when not in solution already, it is dissolved by weak alkalis; such as, lime-water.

mucin therapy
The administration of mucin as therapy for peptic ulcers, to protect the gastric mucosa against the action of pepsin and hydrochloric acid by protective coating and by neutralization of the hydrochloric acid.
mucinase
1. Any enzyme that acts on mucin.
2. Any of several enzymes that break down glycosaminoglycans (any polysaccharide, or polymer made of many saccharide units linked by glycosidic bonds, which is a polymer of amino sugars; they are the carbohydrate units of proteoglycans).
