The morphological changes of lens formation from different regeneration stages were observed with both microcope and transmission electron microscope.

以无尾两栖类花背蟾蜍后肢芽期蝌蚪为实验材料，摘除其左眼晶状体，在再生不同时期固定，石蜡连续切片，苏木精-伊红对染，光镜观察，研究晶状体再生的组织来源；另外，选再生不同时期材料用戊二醛，锇酸固定，透射电镜观察，以研究晶状体再生组织的超微结构变化。

The experiment was conducted to study the possible effects of toxicity in the toad erythrocyte s induced by dicofol,48 mature toads,Bufo gargarizans,were injected with five different dosages of DCF in coelom every 24 h and 1-4 times in succession,and cells producing micronucleus,nuclear abnormality and cell abnormality were counted separately.

用5种不同剂量的三氯杀螨醇(d icofo l，DCF)分别对48只中华蟾蜍成体进行体腔注射法染毒1~4次，观察并统计中华蟾蜍成体外周血红细胞产生微核、核异常及细胞异常的细胞数。

This essay has made a primary study on the relativity of body temperature of Bufo bufo and environmental factors based on air tempera-ture,earth temperature,relative air humidity etc,so as to provide some certain foundation for the protection of amphibious animals,in particularanura.

本文从气温、地温和空气相对湿度等方面，对大蟾蜍的体温与环境因子之间的相关关系进行了初步研究，以便对两栖动物，特别是无尾类的保护提供依据。
