title: The leukocyte adherence inhibition test in tumor patients using 3M KCl extracts of fetal tissues as antigens.
abstract: The sensitization of tumor patients was evaluated with the LAI test to 3M KCl extracts of human fetuses derived from abortion in the 1st-3rd month, 5th month and 7th month of pregnancy. Positive responses were seen against preparations from fetuses at different developmental stages: reactivity was found among 12/18 (1st-3rd month), 13/15 (5th month) and 14/16 (7th month) of the tumor patients. In total, 80% (39/49) of the patients were sensitized to fetal extracts. In contrast, only 19% (10/54) of the control group reacted positively in the LAI test.
