[Studies into human foetal pancreas--critical appraisal of methods for tissue preparation (author's transl)].

Three different methods of legal abortion were applied to 23 patients, who had asked for termination of pregnancy, between the eleventh and 14th weeks of pregnancy. In vitro studies into human foetal pancreas were taken into consideration, when the choice was made. Carbohydrate tolerance was normal in all cases (50 g oGTT). Timing of intra-uterine foetal death, in the context of the three above methods (B-scan ultrasonic diagnosis and HPL level measurement) as well as studies into in vitro stimulation of foetopancreatic insulin secretion have shown purely mechanical, surgical abortion, sometimes following prostaglandin cervical gel priming, to be indispensable a condition for successful in vitro elucidation of the aetiopathogenesis of foetal diabetes. Extra-amniotic prostaglandin induction of abortion has failed to yield any relevant information, in that context.
