Objective To research the radioprotective effect of bacillus subtilison 60Co-γ-ray-induced injury.
Methods Mice were treated with three different dosesof bacillus subtilis in 60 days. All groups were irradiated once with 60Co γ-ray on thirtieth-day, and then the difference in survival rate, average survival time, the changes in white blood cells, quantity of DNA in marrow cell and serum hemolysin were observed.
Results The 30-day survival rate, average survival time, the WBC counts, quantity of DNA in marrow cell and serum hemolysin of Bacillus subtilis-protected mice were all much higher than those of the control group.
Conclusion Bacillus subtilis had significant anti-radiation effect.
