Protection effect of metal net-like defense cloth on cell after electromagnetic pulse

  Objective   To study the protection effect of metal net-like defense cloth in vivo and genistein on J urkat cell after electromanetic pulse(EMP).

  Methods   Wistar rats and Jurkat cells were exposed to high power EMP of 6×10⁴ V/m as experimental models.By various methods such as biochemical tests, light microscopy, methyl thiazolyl tetrazolium(MTT), flow cutometry, the protection effect of metal net-like defense cloth and protein tyrosine kinase(PTK)inhibitor Genistein on immune organization and cell were investigsted.

  Results   (1) Peripheral blood lymphocyte of rats sheltered with metal net-like defense cloth(EM-4)recovered, more quickly than that of rats unsheltered; (2)Pretreatment with gensitein could partially block the degression of EMP on the proliferation activity and Jirkat cell in S phsase instantly.

  Conclusion   (EM-4) and PTK inhibitor Genistein are effective to protect the immune function, cell proliferation activity and DNA synthesis from EMP radiation.
