A substance secreted by various tissues in the body (the mucous membranes) made up of water, mucin (a glycoprotein), salts, and some cells. In the lungs, mucus serves to lubricate the insides of the airways and to trap inhaled foreign particles so that they can be coughed out. In asthma, however, an excess of mucus is produced and can actually block airways. Mucus also tends to be thicker and more viscous in asthmatics.


Malignant spreading tumour of the mesothelium of the pleura, pericardium, or peritoneum, arising as a result of the presence of asbestos fibres. It is diagnostic of exposure to asbestos.

Tissue formed by specialized cells lining the chest, abdominal cavities, and the outer surface of most internal organs. Mesothelium helps protect the organs by producing a lubricating fluid that allows the organs to move.

Childhood infectious disease causing rash and fever. A viral infection that may cause hearing loss. It does not always lead to hearing loss, but it can cause a wide range of sensorineural hearing loss from monaural to binaural and mild to profound in degree. Measles has historically been a common childhood disease with rare complications. Mass vaccination has resulted in a dramatic decline in measles incidence, but outbreaks now occur in older populations and in infants born to women whose immunity from vaccination has deteriorated. Periodic epidemics continue to occur. The vaccine is associated with serious adverse reactions including permanent nervous system damage and thrombocytopenia (a decrease in blood platelets responsible for blood clotting with accompanying spontaneous bleeding) all resulting from autoimmune disease triggered by the vaccine. Long-term effects are unknown.

An organism that can be seen only under a microscope. Categories of microorganisms include Algae, Bacteria, Fungi, Protozoa, Viruses, or Subviral Agents. Also referred to as microbe.

Microscopic organism, especially one that transmits a disease.
