17-dione to release a pyrogen by human leukocytes was investigated by two independent methods: supernatants from leukocytes incubated with a steroid are injected to rabbits whose fever is measured, or tested by the Limulus Test (a pyrogen detection technique). The 7-keto substituted etiocholanolone still possessed pyrogenic activity, while the 7 alpha-hydroxyl substituted one did not.
