NITRIC OXIDE AS A MODIFIER OF RADIATION EFFECTS ON SHIGELLA FLEXNERI

Journal Article · · Intern. J. Radiation Biol.

The mode of action of NO as a modifier of radiation sensitivity in aqueous suspensions of Shigella flexneri is different from that of O/sub 2/. NO present during irradiation has a sensitizing effect which is similar, but not chemically equivalent, to that due to O/sub 2/. Exposure to NO followed by removal of the gas prior to irradiation (i.e., pre-treatment) causes a latent irreversible effect on the bacteria, which becomes manifest after irradiation as enhanced radiation sensitivity dependent on concentration of NO and on the time of contact. NO has also a relative protective effect. A tentative hypothesis based on the fixation of NO by unknown cell constituents is suggested. (auth)
