Lens Epithelial Cell Proliferation and Migration in Radiation Cataracts

The left eyes of young and adult mice and rats were exposed to 2400 r of gamma radiation from a Co/sup 60/ source administered at the rate of 40 r/min. The right eyes of the animals served as controls. Thymidine--tritium is incorporated into the deoxyribonucleic acid (DNA) in the synthesis phase of cell division. The number of epithelial cells labeled per section of lens and the number of grains found per cell were taken as a measure of nucleic...
