Objective: To establish the immunorepressive mice model by irradiation.
Methods: The 90 Kunming mice which the weight is from 30 to 34g were treated with 3Gy, 4Gy, 5Gy gamma irradiation, the delayed allergy testing, the serum haemolysin level testing, the phagocytosing functions testing and the NK cell activity testing were performed at 3th, 7th, 14th, 21th days after irradiation respectively.
Results And Conclusion: (1) All 3Gy, 4Gy, 5Gy gamma irradiation can cause mice immunorepressivestate except the NK cell activity. (2) The time of comeback after irradiation is different from immunity items. The serum haemolysin level is most sensitivity in all, but it comeback most slowly after irradiation. The phagocytosing functions comeback most rapidly after irradiation. (3) It suggests that the irradiation immunorepressive mice model can be established using it in order to evaluate the enhanceing immune function, assisting irradiation hazard protection function and alleviating toxicity function of irradiation treatment and chemical treatment. (4) The NK cell activity is not suitably to immunorespressive by gamma irradiation.

Unlabelled: Cells that undergo apoptosis in response to chemical or physical stimuli repress inflammatory reactions, but cells that undergo nonapoptotic death in response to such stimuli lack this activity. Whether cells dying from viral infection exhibit a cell death-type modulatory effect on inflammatory reactions is unknown. We compared the effects on macrophage inflammatory responses of cells dying an apoptotic or a nonapoptotic death as a result of adenoviral infection.
