title: Hyperglycemia and reproductive defects in non-diabetic gravidas: a mouse model test of a new theory.
abstract: The frequent association of various reproductive anomalies with maternal diabetes is explained by a theory that predicts such defects will occur even in transient moderate hyperglycemia in non-diabetic gravidae. A first test of this hypothesis produced strongly supportive results in a mouse model. Thirteen C57BL/6J dams on a grain (control) diet produced (in the 4th week after first mating) 64 pups, 62 surviving to maturity. In the same time interval on a high sucrose diet, fourteen isogenic dams produced only 5 pups, none surviving 5 days (p much less than .001). Additional ongoing studies of the underlying glucose-ascorbate antagonism and of early vs. perinatal hyperglycemia are described briefly.
