[Carbohydrate metabolism in normal AG Wistar rats, "nude" mutants, and furred hybrids]

Whereas in three-months old rats the blood glucose level appears normal in all three groups of animals, glucose tolerance tests show a great impairment in hybrids as compared to normal and "Atrichis" rats. Such an impairment is seen in prediabetes. Furthermore, in eight-month old rats, blood glucose and lipids are increased in hybrids but are normal in "Atrichis" and normal rats.
