Abstract

Severe starvation caused minor morphologic changes in porcine eye lenses, fine punctate opacities in cortex, a few water vacuoles, and enlarged, prominent Y sutures. However, these abnormalities disappeared upon rehabilitation. The sedimentation analyses of porcine lens soluble proteins exhibited three components with values for S°20, of 18.2, 9.0, and 2.7 S. The relative distribution of these components were 21, 38, and 41 per cent for 18.2, 9.0, and 2.7 S components, respectively. The sedimentation patterns and the distribution of three protein components were not affected by severe starvation.
