a quantitative electron microscopic immunogold technique applied on ultrathin sections of the retinas of these animals showed that the labeling densities of collagen type iv and laminin per unit cross-sectional area ( which is presumably proportional to the concentrations of these molecules ) were significantly increased in the retinal capillary basement membranes of galactose-fed rats , compared with animals on the control test diet .
