Significant muscle capillary basement membrane thickening in spontaneously diabetic Mystromys albicaudatus.

Skeletal muscle capillary basement membrane thickness was determined in age- and sex-matched normal and spontaneously diabetic Mystromys albicaudatus. In nondiabetic animals the average basement membrane thickness was 482.6+/-48.7 A as against 779.0+/-319.9 A in the diabetic ones. This difference was statistically significant at P less than 0.005.
