Comparative studies on mechanisms of endotoxin and prostaglandin E fever limit in rabbits / 中国病理生理杂志

ABSTRACT

0.05) after non-fever limit (non-FL) dose and FL dose endotoxin (ET) was intravenously injected into rabbits. The increase of PGE_2 in CSF was not limited during the occurrence of ET FL. 2. Intracerebroventricular injection (ICV) of different dose of PGE_2 into rabbits induced dose-dependent fever, but there was no more rise in body temperature when the febrile response had reached a certain height. This is termed "PGE FL". 3. The concentration of cyclic adenosine-3′, 5′-monophosphate (cAMP)in CSF paralleled the fluctuation of temperature (r=0.9906, P
