the shift of suppression from a tolerizing hapten to a so-called bystander antigen was investigated in this study using contact hypersensitivity to trinitrochlorobenzene ( tncb ) and dinitrofluorobenzene ( dnfb ) and delayed type hypersensitivity ( dth ) to alloantigens in the rats as experimental models .
