The authors attempt to assess the relationship between exercise, diabetes, and bone metabolism. An animal model system was developed to study the relationship. Animals given streptozotocin to induce a type I diabetic state show elevated plasma glucose and triglyceride levels and a decrease in body weight. Analysis of femurs revealed alterations in copper, phosphorus, and zinc levels in animals with diabetes compared with controls. Mineral analysis of femurs from diabetic animals placed on an exercise regimen revealed values closer to control levels.
Diabetes mellitus is a disease in which the capillary basement membranes are substantially altered. This diabetic microangiopathy is characterized by a thickening of the basement membrane and changes in its permeability characteristic due to a disturbance in the production and distribution of its functional components. Glucose metabolism and insulin imbalance have been implicated in these basement membrane modifications. The authors describe normal capillary basement membrane architecture and then discuss how pathologic changes caused by diabetes mellitus are related to diabetic foot pathology.
This study is an attempt to assess the role of dietary supplementation in the treatment and prevention of diabetic peripheral neuropathy. The authors developed an animal model system to study this problem. Animals given streptozotocin to induce a type I diabetic state showed elevated glucose levels and decreased body weight. Analysis of the sciatic nerve revealed a decrease in nerve conduction velocity and Na(+)-K(+)-ATPase activity. The activity of protein kinase C, another component of the nerve transmission process, was also affected by the diabetic state. The dietary intervention of polyunsaturated fatty acids seemed to revert some of these changes toward normal.
