Abstract
OXYGEN is known to increase the effectiveness of X-rays in killing bacteria1,2 and cells from many other organisms3 by a factor of 2 or 3. There have been numerous reports of substances which protect against the effects of irradiation under aerobic conditions4, but there does not appear to be any report of a substance which, in complete anoxia, raises the radiosensitivity of bacteria to the level normally associated with full aeration. Before giving the evidence which suggests that nitric oxide may be such a substance, we may consider the factors which first directed attention to this gas.
