Pyrogenic
Definition:
(a.) Producing heat; -- said of substances, as septic poisons, which elevate the temperature of the body and cause fever.
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.

(10) Protein malnutrition leads to diminished pyrogenicity of macrophage culture supernatants and may be at least partly responsible for the decreased febrile response seen in the malnourished animals.
(11) In its monomer form, endogenous pyrogen is a potent fever-producing substance and mediates fever by its action on the thermoregulatory center.
(12) Immobilized histidine and immobilized histamine could be used for the removal of natural pyrogens contaminating various useful low-molecular-weight compounds as well as high-molecular-weight compounds such as proteins.
