Blood glucose control and glomerular capillary basement membrane thickening in experimental diabetes.
Fox CJ., Darby SC., Ireland JT., Sönksen PH.
Glomerular capillary basement membrane thickness (BMT) was measured in 23 rats which had had streptozocin-induced diabetes for 14 months and in 12 age-matched controls. Diabetic rats were randomly allocated to different groups, either receiving no treatment or treated with a low carbohydrate diet or insulin, or both. Control rats were randomly allocated to a normal or low carbohydrate diet. Among the diabetic rats mean plasma glucose concentrations for the groups ranged from 27-4 mmol/l (494 mg/100 ml) in the untreated rats to 9-8 mmol/l (177 mg/100 ml) in those receiving both a low carbohydrate diet and insulin. A highly significant positive relation was found between BMT and plasma glucose concentration for individual rats. When BMT was corrected for body weight a similar relation was observed.
