[Development of a model to study the anti-edema properties of Ginkgo biloba extract].

The vasogenic edema observed after irradiation of the brain constitutes a new and interesting model to study the anti-oedema properties of drugs. We have just completed a first pharmaco-clinical study of Ginkgo biloba extract with the dual purpose of assessing the feasibility of a therapeutic protocol and of deciding on simple and non-invasive criteria that would quantity cerebral oedema. The results of this pilot study have encouraged us to pursue our investigations under strict methodological conditions, in view of their therapeutic but also epidemiological interest.
