[Stress ulcer by hypovolemic shock in pregnant and normal rabbits and in the fetuses (author's transl)].

The purpose of this experimental work was to study the possibility of stress ulcer in fetal Surgery. Firstly an experimental model of production of stress ulcer by hypovolemic shock was worked out: by removing a volume of blood equivalent to 2% of body weight out of the femoral artery, a stress ulcer was was regularly induced in 25 female rabbits in the fundic area within 3 hours. In 10 pregnant rabbits and in the fetuses a stress ulcer could not be produced by the same method. This observation suggests the hypothesis that the reactions of the gastric wall are modified by the specific hormonal situation of the pregnant rabbit. This assumption ought to be elucidated by further investigations.
