However, non-infectious febrile morbidity attributed to endogenous pyrogenic mechanism might be considerable.

The sharp increase was attributed to the contribution of pyrogenic sources of PAHs.

The annual burning of sugarcane fields prior to harvesting emits huge amounts of pyrogenic particles.

Hemorrhage-induced high level of corticosterone might contribute to the attenuation of fever, perhaps via the suppression of pyrogenic cytokines.

Conclusion: These results indirectly indicate that NO is involved in pyrogenic and behavioral responses in rats during turpentine abscess.
