[Immunoreactive insulin in the CNS of human fetuses and newborn infants of metabolically healthy and diabetic mothers--an immunohistochemical study].

The cellular localization and regional distribution of "insulin-like immunoreactivity" and "C-peptide immunoreactivity" were studied in brains of fetuses and newborns from normoglycaemic and diabetic mothers using immunohistochemical techniques. It is shown that "insulin-like material" and "C-peptide-like material" occur in the same nerve cells. No differences in regard to the localization of both polypeptides exist between abort material from normoglycaemic and diabetic mothers.
