We got the result: Bufo Raddei Strauch Tadpole (1) Bufo Raddei Strauch Tadpole was capable of lens regeneration, which originated from the epithelial cells at iris dorsal margin by dipigmentation.(2) Dipigmentation of Bufo Raddei Strauch by two methods: one was licked up by amoebocyte, the other one was flowed from the pigment cells.(3) In the lens regeneration cells of Bufo Raddei Strauch profiles of the mitochondria became complicated ribosome manifold, and the endoplasmic reticulum was cisternal dilation. During the process of deferentiation of lens fiber the cell nucleolus became little and chromatin shrinked.(4)The crystalline electrophoresis of Bufo Raddei Strauch Tadpole lens regeneration showed that during lens regeneration P-crystalline was expressed earliest then was γ-crystalline and α-crystallin, this result is consistent with newt.

The cytotoxicity of the target biomaterial was graded according to the national standards. The growth manner of the human intrahepatic bile duct endothelial cells seeded on the acellular lumens matrix was studied after 20 d under scanning electron microscopy.

The results shown that:(1) Bufo raddei Strauch tadpole was capable of lens regeneration, which originated from the epithelial cells at dorsal iris margin by depigmentation.(2) Depigmentation of Bufo raddei Strauch during lens regeneration was by two methods: First, pigment granules initially dispersed all over the cytoplasm were moved towards the periphery of the cell, and then were directly taken up by the amoeboid cells. Second, pigment granules in a cell were first crowded in a mass, surrounded by a membranous structure in the cytoplasm, which were eventually discharged as a mass from the cell.
