[Investigation of pregnancy hypertension as a consequence of utero-placentar ischemia (author's transl)].

An attempt at provoking gestosis by constricting the uterine artery was made using pregnant rats and rabbits. The experiment failed. Reducing the circulation by means of Z-sutures in the region of the nidation site failed to produce symptoms of gestosis also. The result of the uterine manipulations was abortion and intra-uterine retardation of the product of conception. Though it was not possible to verify the pathogenesis of gestosis due to impaired circulation of the uterus. On the basis of these experiments previous gestosis hypotheses stemming from animal experiments cannot be questioned. However, it is though-provoking that a review of the literature reveals that the results of these "classical model experiments" cannot always be interpreted uniformly.
