Immunologic mechanisms in psoriasis have been postulated previously,1 but convincing experimental evidence for such mechanisms has not been shown. Aswaq, Farber, Moreci, and Raffel2 demonstrated delayed type skin reactions, using a modified passive cutaneous anaphylaxis technique5 with psoriatic plaque homogenate as antigen and human psoriatic serum as antibody.
Our present study was designed to explore such possible antigen-antibody mechanisms and, if successful, to expand such studies to other skin disorders thought to be subject to autoimmune mechanisms.
Materials and Methods
Albino male guinea pigs, weighing 250-750 gm., were used. The abdomen or back of each guinea pig was shaved 12-24 hr. prior to the intradermal injection of psoriatic and/or normal human control serum. The patients were divided into 2 groups. Ten patients with psoriasis were in the study group. They had no neoplastic, infectious, or metabolic disease (except for one patient with gout). The control patients were
