    Abstract:
    Observations have been made over a period of 16 weeks on three groups of rats: controls, untreated streptozotocin-diabetics and diabetics treated with continuous subcutaneous insulin infusion. Good control of circadian and diurnal blood glucose levels was achieved in the insulin-treated diabetics. Body weights and tibial lengths were reduced in untreated diabetics and improved, but not normalized, by insulin therapy. Kidney weights were similar in all groups. Glomerular size and number, tubule volume, glomerular basement membrane volume and surface area were essentially the same in all groups. However, the untreated diabetics possessed tubules of larger diameter and shorter length than those in controls. Both variables were preserved at normal values by insulin infusion therapy. These results illustrate the value of early blood glucose control for preventing at least some of the structural alterations associated with experimental diabetic nephropathy.
