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.
