to test the hypothesis that immunopotentiation of the maternal immune system is beneficial for the developing embryo , we examined ( 1 ) the effect of specific preimmunization with paternal leucocytes in women and balb/c splenocytes in cba/j x dba/2j mice ( which show increased % fetal resorption ) and ( 2 ) the influence of non-specific potentiators such as complete freund 's adjuvant and thymus humoral factor on the abortion rate in cba/j mothers .
