Abstract
Skin reactions with SK·SD, PPD and PHA and leucocyte adherence inhibition test using SK·SD antigen were performed on 1) healthy controls (28 persons aged between 20 and 59 and 23 persons over 60), 2) 36 patients with disturbances in cellular immunity and 3) 34 patients without this disturbance, in order to assess the usefulness of skin reaction using SK·SD antigen. The skin reaction with SK·SD was useful as one of the markers of cell mediated immunity for patients between 20 and 59 years, while the LAI test using SK·SD antigen seemed to be of little use.
