It is well known that if the original lens is removed from the eyeball in certain Urodeles, a new lens will regenerate from the dorsal iris. Experiments were designed to study the different effects on lens regeneration in the newt, Triturus viridescens, between the light and dark preadapted animals and light and dark non-preadapted animals. The preadapted animals were preadapted to continuous light or dark for 90 days prior to lentectomy. The newts remained in the same controlled environments postlentectomy for 25 days to test the effect of light preadaptation on lens regeneration. The non-preadapted animals were placed in the light controlled environment immediately after lentectomy for a 25-day regeneration period. The results indicated that there was no difference in the rate of regeneration between continuous light preadapted and non preadapted animals. However, the dark non-preadapted animals regenerated new lenses at a much slower rate than the dark preadapted animals. The rate of lens regeneration was similar among the controls with 12 hours of light per 24-hour period, the dark preadapted, the continuous light preadapted, and continuous light non-preadapted groups.
众所周知，在某些有尾两栖动物中，如果将原始晶状体从眼球中摘除，新的晶状体将从背侧虹膜再生。实验旨在研究预先适应光照和黑暗的动物以及未预先适应光照和黑暗的动物对绿螈晶状体再生的不同影响。预先适应的动物在晶状体摘除术前90天预先适应持续光照或黑暗环境。晶状体摘除术后，蝾螈在相同的受控环境中饲养25天，以测试光照预适应对晶状体再生的影响。未预先适应的动物在晶状体摘除术后立即置于光照受控环境中，进行为期25天的再生期观察。结果表明，持续光照预适应动物和未预适应动物的再生速率没有差异。然而，黑暗环境中未预适应的动物晶状体再生速度比黑暗环境中预适应的动物慢得多。在每24小时有12小时光照的对照组、黑暗预适应组、持续光照预适应组和持续光照未预适应组中，晶状体再生速率相似。
