ROUTINE PYROGEN TESTING
1 The examination of preparations from large‐scale manufacture for freedom from pyrogens is described. 2 Typical results from the examination of 11. and 0·51. packs of water for injection, glucose‐saline and solution and normal saline solution are presented. 3 Evidence supporting the claim that reduction in the pyrogen levels take place on storage is provided.
Radiation-induced Hyperpyrexia in Rabbits
THE response of rabbits to 25,000–50,000 r. radiation exposure is death within 3–4 hr.1. Even at lower levels of radiation exposure to 600–1,000 r. a shock like death occurs in a few animals within 24–48 hr.2. However, other biological responses which occur more consistently at these lower radiation dose-levels are depression of the white cell count and reduction in bone marrow activity3. This investigation presents evidence that a rise of body temperature is also a regular effect of acute radiation exposure in rabbits.
