Abstract
The kinds and methods of preparation of adjuvants for sensitization to PPD were experimented in guinea pigs.
Results: As adjuvant emulsion of arlacel A and bayol F, arlacel A and drakeol and arlacel A and Krearol were capable of the similar sensitization. But emulsion of paraffin oil and anhydrous lanoline were less effective. The proportion of arlacel A and bayol F was best in 1: 9 (volume/volume). Inoculation with 2mg or 0.2mg of PPD had capacity of the similar sensitization. Emulsion of PPD with Tween 80 were lower sensitive than PPD without Tween 80.
