FREE AND ESTERIFIED STEROLS IN SURFACE LIPIDS FROM UNINVOLVED SKIN IN PSORIASIS

[摘要] The esterified-free sterol ratio in skin surface lipids is different at different times following defatting of the skin surface. In a comparative study of surface lipids from the lesion-free back areas of normal and psoriatic subjects, the amounts of sterols present in esterified form was not significantly different, provided the lipid samples for analysis were collected not more than 12 hr. after defatting.
