Results and discussion
Results of examinations
- Details on results:
- Ethylenethiourea suppressed the primary and secondary immune response in mice and to a lesser extent also inhibited the primary immune response mitogen-stimulated lymphocyte proliferation in vitro. Studies in T cells revealed that ethylenethiourea suppressed the activity of both helper T cells and suppressor T cells.
