The present research aims at showing the role played by the lens in inhibiting lens-forming transformations of the outer cornea of Xenopus laevis tadpoles. Two types of experiment were carried out: 1) lentectomy and insertion of a Millipore filter disk at the side of the lens, and 2) lentectomy and insertion of a Millipore disk with a central hole. Results indicate that when the lens is replaced by a mechanical obstacle capable of preventing direct communication between vitreous and anterior chambers, definite inhibition of the lens-forming transformations of the outer cornea occurs. These data strongly suggest that the inhibition exerted by the lens on lens-forming transformations of the outer cornea in Xenopus laevis eyes is mechanical rather than chemical in nature.
本研究旨在揭示晶状体在抑制非洲爪蟾蝌蚪外角膜形成晶状体转化过程中所起的作用。进行了两种类型的实验：1）晶状体切除术并在晶状体一侧插入微孔滤膜盘，以及2）晶状体切除术并插入带有中心孔的微孔盘。结果表明，当晶状体被能够阻止玻璃体与前房直接连通的机械障碍物取代时，外角膜的晶状体形成转化会受到明确的抑制。这些数据有力地表明，晶状体对非洲爪蟾眼睛外角膜晶状体形成转化的抑制本质上是机械性的而非化学性的。
