title: [Studies on the cytotoxicity of lymphocytes in ulcerative colitis].
abstract: Cytotoxic action was examined with 51 Cr labelled fetal human colon epithelial cell cultures -- using lymphocytes of healthy test persons and of patients suffering from ulcerous colitis and colon carcinoma. There was no significant difference as to the cytotoxic action of the lymphocytes between the three above-mentioned groups; these results are in contrast to those obtained by previous research. This fact is considered to be due to the different methods applied. In the cases with ulcerous colitis E. coli or E. coli with CEA together formed the antigen against which complex immuno-processes are generated.
