title: Inhibition of human blood platelet aggregation by photochemotherapy in vitro and in vivo.
abstract: Irradiation of human blood platelets with UV-A in vitro impairs their ability to aggregate after challenge with collagen. There also appears to be mild and transient inhibition of platelet aggregability in psoriatics during the fourth week of photochemotherapy.
