title: [Effects of radiation injury on peripheral blood and liver NO concentration in mice].
abstract: OBJECTIVE
  To study the effect of radiation injury on nitric oxide (NO) concentration in mouse peripheral blood and liver.
  
  
  METHODS
  NIH mice were subjected to gamma-ray exposure at 9.0 Gy and transferred immediately in room temperature condition. NO concentrations in the liver and peripheral blood were examined before and at different time points after the exposure.
  
  
  RESULTS
  Compared to that before exposure, NO concentration in the peripheral blood and liver significantly increased after gamma-ray exposure. NO concentration in the peripheral blood began to increase 3 h after the exposure, but that in the liver increased till 6 h after the exposure.
  
  
  CONCLUSIONS
  Radiation can cause the increase of NO concentration in the peripheral blood and liver, but different tissues may exhibit different response intensities to radiation.
