Abstract:
In order to obtain monocytic endogenous pyrogen, Ficoll—Hypaque's separation technique was used in this paper. We obtained mononuclear cells from rabbits' blood in vitro and added endotoxin free saline to make suspension in the concentration of 0.65?10~6/mL. Endogenous pyrogen was produced from monocytes by stimulation of purified endotoxin of colon bacilli and incubation in saline at 37-38℃ stirred and shaked continuously for 10 hr. There is EP in collecting fluid after centrifugation and ultrafiitration.The result obtained shows:1. Employing Ficoll-Hypaque's separation technique, high concentration monocytic endogenous pyrogen can be obtained.2. Monocytic endogenous pyrogen have marked febrile effect.
