using a material consisting of related dermal specimens and 24-h urine samples from 17 psoriatics and 20 non-psoriatics it has been shown for the first time that the excretion of dermatan sulphate and a fraction of chondroitinase abc resistant gag ( 'heparan sulphate ' ) are positively associated with the tissue content of the analytically identical glycosaminoglycans in dermis .
