Pyrogen


Definition:

  • (n.) Electricity.
  • (n.) A poison separable from decomposed meat infusions, and supposed to be formed from albuminous matter through the agency of bacteria.

Example Sentences:

  • (1) Central injections of 40 and 80 ng of [Nle4,D-Phe7]-alpha-MSH caused hypothermia in afebrile rabbits, whereas 20 and 10 ng, which had no effect on afebrile body temperature, caused greater than 40% reduction in leukocytic pyrogen-induced fever.
