Abstract

PAS staining was used to assess the glycogen content of psoriatic epidermis, in 35 patients with active psoriasis, 25 patients with inactive psoriasis and 21 normal control subjects. The investigations were also carried out by the disease type, sex, duration of illness, site of biopsy and subjective syrrptom such as itching sensation. Being compared with the active, izractive and normal control groups,7 of R5 active cases and 4 of 25 inactive cases were resulted in strong PAS positive reactions. In 21 ornmal aontrol group, the most cases gave PAS negative reaction, except 2 cases of the week PAS positive reactions. Being compared with disease types, 11 of 5I psoriasis vulgaris cascs was resulted in strong PAS positive reactions and psoriasis guttata cases were resulted in slight PAS positive reaction. among half of their ca.ses. Being iompared with the FAS staining intensity in accordance with the itcbing eensation, R of 6 with severe itching and 4 of 29 cases without itching were resultel in strong PA3 posltive reactions. There were no significant differenees in the sex, age, duration of illness and biopsy site aspects.
