Study on repairing function of wheat embryo extracts(WEE) on radiation damage

  Objective   To study repairing and adjusting function of WEE on radiation damage of mice.

  Methods   The mice's whole bodies were irradiated with a x-ray source and were divided into experimental groups of fed WEE for 10 days before due date or same time but the control was not irradiated only.General symptoms, and 30-day survival rate, and marrow micronucleus rate, and leukocytes to varying time were observed.

  Results   Compared with the control, the symptoms of experimental groups were remarkable better in damaged skin of head and face, intestine mucosae, kidney, etc.30-day survival rate was 86.17% which was raised 41.79%.Porective coefficient was 1.72 and marrow micronucleus rate 4.62‰ lower than the control(12.14‰, P < 0.01).The leukocytes of experimental mice were picked up rapidly on 7, 13, 20, 30 days and were different from the control(P < 0.05, P < 0.01, P < 0.01, P < 0.01).

  Conclusion   WEE can adjust bio-activity for repairing irradiated damages, and might play an important role in radiotherapy of tumor.
