-
The sensitization of an animal, such as a guinea-pig, to a foreign proteid, so that a second dose finds an exaggerated susceptibility to the foreign substance. A guinea-pig injected with 0.01 c.c. of horse serum and in 10 to 12 days again injected with from 3 to 5 c.c, will die in about 10 minutes with respiratory failure, clonic spasm, and paralysis. The sensitized cells have probably produced receptors which grasp the non-poisonous moiety of the proteid and thus the poisonous group is liberated and acts.
-
A state of excessive susceptibility to the action of a toxin or drug after repeated injections or use. [Gr.]
