- Abstract
- Diabetes during pregnancy induces specifically structural and functional changes in the fetal endocrine pancreas. Other organs are affected as well. In this study, the fetal intestinal tract which is in close connection with the endocrine pancreas was analysed during diabetic gestation. The disease was induced by two different doses of streptozotocin which led to a mild or severe diabetic state in the mother. In fetuses from mildly diabetic as well as from severely diabetic rats, the time sequence in the appearance of the differentiated cells was identical and similar to that of controls. However, morphometric analysis of the intestine of fetuses from severely diabetic rats revealed a decrease in each of the parameters measured which led to a general hypotrophy of the intestine. In the fetuses from mildly diabetic rats, the values of the morphometric parameters of the duodenal mucosa remained unchanged and comparable to those of the control group. The vascularisation of the duodenum is modified in these fetuses because the volume density of the blood vessels is significantly increased. In conclusion, both diabetic states of the mother induce various alterations in the fetal intestine, including the blood vessels. The nature of the structural changes observed in the intestine could lead to modifications in the function of the entero-pancreatic system in these fetuses.
