the experiment has been done on 63 patients affected by allergic contact dermatitis and sensitized to potassium dichromate and on 76 non allergic subjects to control : if leukocytes ( separated in emagel ) , mononuclear cells ( separated in lymphoprep ) and t-lymphocytes ( separated through rosettes with neuraminidase ) bind the 51cr , if this binding depends on the valence ( cr3+ and cr6+ ) and on the type of cells and if it is conditioned by the hypersensitivity .
