Macrophage migration inhibition (MM 1) tests have been carried out using lymphocytes from twenty-six patients with malignant disease and from twenty-two other subjects. The antigens used were the same as those employed in the macrophage electrophoretic mobility (MEM) test. The results indicate that the information obtained using the MM! test is similar to that found with the MEM test. [ABSTRACT FROM AUTHOR]

This paper describes further confirmation of the successful application of the macrophage electrophoretic mobility (MEM) test to the detection of malignant disease. Results from fifty-one patients and eighteen controls are presented. The apparatus and technique used for the measurement of macrophage elctrophoretic mobility differed from those previously used in other investigations. Further information is presented on the nature and behaviour of macrophage slowing factor(s), and experiments concerning the possible use of cells other than guinea-pig macrophages as indicators of slowing factor production are also described.
