[Reflexphotometric determinations of vasoconstriction after topical application of steroids. IV. Time slope of vasoconstriction and reactive vasodilatation (author's transl)].

In this study a reflex photometrical technique has been used to examine local steroid induced vasoreactions. When applied but once, steroids cause a maximum vasoconstriction between 8 and 16 h after beginning the test. Followed by a 32 h period, the phase of vasoconstriction is succeeded by a dilatation of dermis blood vessels. It appears, that the stronger the vasocontriction, the smaller the degree of vasodilatation.
