Saitoh t(1), kusunoki t, yao t, kawano k, kojima y, miyahara k, onoda j, yokoi h, ikeda k. Transmission electron microscope (tem) therefore plays a vital role in identifying such changes. A stereologic assessment stereologic methods are superior to model based techniques in estimating gbm thickness and should be regarded as the technique of choice in this area. It is accepted that this effect will be random, and a correction factor of π/46may be used to convert the observed membrane thickness to true membrane thickness.

Muscle capillary basement membrane thickening occurred in 32 of 39 diabetics, using the siperstein method, but patients with proliferative retinopathy did not exhibit thicker basement membranes than patients with no or minimal changes in the retina.
