Biochemical and morphological changes in rat lenses after long-term UV B irradiation.

abstract：:To investigate the binding of peanut-agglutinin (PNA) on porcine corneal tissue, several methods of tissue processing were used. In cryostat sections of postmortem tissue, PNA labeling of epithelial cell membranes was detected. In the stroma, a fibrillar structure parallel to the corneal surface was found. The anterio...
