in order to determine whether or not abnormal suppressor cell function correlates with the absence of a delayed hypersensitivity reaction ( dhr ) in anergic patients , con a reactivity and the short-lived suppressor cell activity of peripheral blood lymphocytes ( pbl ) were studied in 4 groups of patients : ( 1 ) those with peripheral vascular disease ( pvd ) who reacted with a normal dhr to the intradermal injection of one or more recall antigens ;
