The electron paramagnetic resonance method was used to study the intensity of nitric oxide production by analyzing the amount of NO-containing paramagnetic complexes in the heart, liver, and spinal cord tissues of 7- and 16-week-old rats growing under restricted mobility conditions. Nitric oxide production was assessed by the intensity of the EPR signal belonging to the (DETC)2-Fe2+NO complex. The results obtained show that growth under conditions of restricted motility leads to an increase in NO production in all organs under study, with the greatest increase observed in 7-week-old rats. Keywords: nitric oxide, heart, liver, spinal cord, electron paramagnetic resonance.
