Effect of selenium-enriched protein on immune function of mice

  Objective   To study the influence of selenium-enriched proteins, which were made from selenium-enriched milk, on the immune function of the health mice.

  Methods   For ty-eighthealthy mice were chosen and randomly divided into 4 groups:nor mal milk g roup, normal milk+inorg anic selenium(Na₂SeO₃)group, selenium-enriched milk group, seleniumenriched protein group.30days later, the index of lymphoid organ of mice, delayed-type hypersensitivity(DTH), the number of plague forming cell were determined, respectively.

  Results   The selenium-enriched protein could increase the number of plague forming cell(PFC), and stimulated DTH.Its influence on the immune of the mice was stronger than those form normal milk+inorganic selenium group and selenium-enriched milk group under the same dosage.

  Conclusion   The seleniumenriched protein can improve cellular immunity and humoral immunity of mice.
