摘要

New pharmaceutical compositions (A) contain 0.01-20 (preferably 0.11-20, especially 0.5-5) wt. % beard lichen ( Usnea barbata) extract (I) and 0.01-80 (preferably 0.11-20, especially 0.5-5) wt. % St. John's wort ( Hypericum perforatum) extract (II). ACTIVITY : Antiseborrheic; Dermatological; Vulnerary; Antiinflammatory; Antibacterial; Fungicide; Antipsoriatic. MECHANISM OF ACTION : UV-induced collagenase activation inhibitor; UV-induced prostaglandin E 2 synthesis inhibitor. In tests in primary human fibroblast cultures, the active collagenase (MMP-1) content (initially ca. 3.0 ng/ml) was increased to ca. 8.0 ng/ml by UVA-1 irradiation (60 J/cm 2>) to ca. 8 ng/ml; and on subsequent incubation for 24 hours with Usnea barbata extract (0.1 v/v) or a combination of the Usnea barbata extract (0.1 v/v) and Hypericum perforatum extract (0.1 v/v) was reduced to ca. 5.2 ng/ml or ca. 0.8 ng/ml respectively.
