What's the difference between pyrogenic and pyrogenous?

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.
  • (2) In the active phase all the patients exhibited an abrupt increase in the activity of alkaline and acid phosphatase in blood neutrophils, a drop in the level of CP (in 69%), a rise in the activity of MP (in 32%); pyrogenal did not induce any capacity for restoring HCT (in 44%).
  • (3) MAbs W1-W3 derived from mice, which were immunized with whole cells of the strain Moulton, reacted with the serogroups Canicola, Icterohaemorrhagiae and Pyrogenes.
  • (4) Interleukin-1 alpha (IL-1 alpha) and interleukin-1 beta (IL-1 beta) are thought to be endogenous pyrogens, i.e., to mediate fever production; warm-sensitive (W) and cold-sensitive (C) neurons in the preoptic area (POA) are presumed to be the ultimate targets of endogenous pyrogens.
  • (5) The Limulus amebocyte lysate test has been used for determination of pyrogens in sugar of different qualities.
  • (6) The minimum pyrogenic dose in both new-born and adult guinea-pigs was 0.25 microliter, but the 0 to 5-day old animals which responded with a fever to this dose were few in number and large in weight; 'small-for age' neonates became hypothermic.
  • (7) Twelve serovars included in the study were: australis, autumnalis, ballum, bataviae, bratislava, canicola, copenhageni, grippotyphosa, hardjo, pomona, pyrogenes, and tarassovi.
  • (8) Another property shared by IL 1 and IL 6 is their pyrogenicity.
  • (9) IL-6 induction was also observed after pretreatment with indomethacin, indicating that the effect was dissociated from the pyrogenic activity of IL-1.
  • (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.
  • (13) Reusing hemodialyzers more than 20 times and, in some instances, also using manual reprocessing systems was significantly associated with clustering of pyrogenic reactions regardless of the type of germicide used.
  • (14) The effects of various kinds of drugs on the pyrogenicity of toxic shock syndrome toxin 1 (TSST-1) and its capacity to enhance the lethal effects of endotoxin in rabbits were studied.
  • (15) The hyperthermic response to pyrogen was not potentiated by caffeine or theophylline administered i.p.
  • (16) With regard to Group I, there was a high number of positive (32.3%) and a variation in the frequency of serovars, the results being as follows: L. butembo (38.8%), L. pomona (33.3%), L. bratislava (31.4%), L. icterohemorragica (12.9%), L. borincana (3.7%) and finally L. canicola, L. pyrogenes, L. wolffii and L. bataviae (1.8%).
  • (17) Parenterals, sterile preparations intended to be injected in man or animal, should be free from pyrogenic substances which are able to raise the thermostatic setting in the hypothalamus.
  • (18) Titers for Leptospira interrogans serovars grippotyphosa, pyrogenes, djasiman, butembo, and pomona were demonstrated.
  • (19) The fever responses of the animals were remeasured 3 days later, and in every case there was a marked enhancement of the fevers produced, using the same doses of endogenous pyrogen that were used earlier.
  • (20) The results were compared with rabbit pyrogen tests.

Pyrogenous


Definition:

  • (a.) Produced by fire; igneous.
