title: The effects of endotoxin pretreatment on subsequent challenge of mice with cycloheximide and a small dose of endotoxin.
abstract: Mice treated with 15.0 micrograms of S. enteritidis endotoxin are completely protected against the coagulopathic effects, but only partially protected against the fatal glucocorticoid deficiency which follow an otherwise lethal challenge with cycloheximide and 5.0 micrograms of the same endotoxin given 3 days later. Hydrocortisone treatment results in survival of all such tolerant, challenged animals. The protection conferred against occlusion of glomerular capillaries by fibrin coagula is abolished by EACA, suggesting that tolerance has induced high levels of fibrinolytic activity by the time of challenge, and evidence indicates that this protective degree of fibrinolytic activity persists for more than 24 h after cycloheximide and endotoxin challenge.
