In vivo and in vitro effect of toxic and radio-detoxified endotoxin preparations on chemiluminescence of peritoneal cells of mice.

: Chemiluminescence (CL) of peritoneal cells was investigated one and five days after injection of toxic and radio-detoxified endotoxin. The CL was triggered by toxic and radio-detoxified endotoxin. The radio-detoxified endotoxin has less pronounced in vivo activating effect than the toxic endotoxin. As triggering agent the toxic endotoxin was more effective than the radio-detoxified endotoxin. However, the radio-detoxified endotoxin has preserved some in vivo activating and in vitro triggering effect.
