Methods Tissue culture was used to study the cataractous lenses of rats induced by sodium selenite or galactose. At the early stage, the content of nonprotein sulfhydryl, protein sulfhydryl, non-soluble disulfide bond, malonaldehyde and the activities of glutathione peroxidase, glutathione reductase and glutathione-S-transferase were measured in the cataractous lenses, and they were compared with that of the normal lenses. Results The two kinds of material could all induce cataract in rats, sodium selenite being more potent.
