| Abstract: | The effects of low and ultra-low doses of X-ray radiation and neutron fluxes produced by continuous-wave and pulsed sources of different nature and power on the activity of plant peroxidases and the bovine lung angiotensin-converting enzyme were studied. Certain ranges of doses (including ultra-low), the exposure to which under particular conditions causes the in vitro activation and/or inactivation of the enzymes, were found. Possible factors responsible for this phenomenon are discussed. |
