Wormlike contraction of the dartos muscle following sudden cold application to the perineum.  

A veil-like smooth muscle just under the skin of the labia majora.  

Resembling the tunica dartos in its slow, involuntary contractions.  

Chemical element 110. A synthesized radioactive metal with a very short half-life.  

A room designed to be devoid of light. The darkroom is necessary for the development of radiographic film. A light-tight chamber, sufficiently aerated, designed for the specific tasks of manipulating and developing radiographic film.  

Any enzymatically mediated chemical reaction that takes place in the absence of light. One example is the series of light-independent reactions that produce glucose from carbon dioxide and cellular energy sources.  

A protein whose presence in the body has been associated with an autosomal dominant (familial) form of Parkinson’s disease.  

Diphtheria, tetanus toxoids, and acellular pertussis vaccine (DTaP), adsorbed.  

A painful, nodular mass in the large bowel, a result of infection with Oesophagostomum bifurcum, a West African worm.  

A phenomenon that illustrates the reversibility of precipitation of antibody and antigen complexes. When a specified amount of diphtheria toxin is added all at once to an antitoxin serum, the mixture is non toxic; but when the same quantity of toxin is added in portions at about 30-min intervals, the mixture is toxic.
