Study on radioprotective effect of bacillus subtilis

  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.
