蝌蚪

In recent years, many toxicology studies have been carried out with anuran tadpoles in China, since they are believed to be perfect indicator species for aquatic pollution.

中文摘要：无尾两栖类的幼体蝌蚪是很好的水体污染指示物种，近年来，国内这方面的研究也越来越多。

After lentectomy through the pupillary hole, the epithelial cells at dorsal iris in Anuran tadpole of Bufo raddei Strauch can undergo transdifferentiation to regenerate a new lens. 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 left lens of Anuran Tadpole - Bufo Raddei Strauch Tadpole and Xenopus laevis Tadpole were removed when they had posterior limb bud. By decapitating and fixing it with Carnoy's fixation fluid in different days, by means of paraffin serial section and Hematoxylin-Eosin stain and by using the microscope to observe the microstructure of lens regeneration of Bufo Raddei Strauch Tadpole and Xenopus laevis Tadpole. By extirpating the left eye and fixing it with aldehyde and osmium acid , by using electron microscope to observe the ultrastructure of lens regeneration of Bufo Raddei Strauch Tadpole and Xenopus laevis Tadpole.

以无尾两栖类—以花背蟾蜍与非洲爪蟾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。

If you want to take care of tadpoles, you should keep them in an aquarium.

如果你想照顾蝌蚪，你应该让他们在一个水族馆。

In this paper, the acute toxicity of 20 substituted aromatics to tadpoles is determined with static methods.

以蝌蚪为模型生物，测定了部分取代芳烃类化合物在静态实验系统中的24h急性毒性效应。

When the tadpole hatches, it is carried on one of the parents' back to a bromeliad where the parents feed it small insects, ants, spiders, crustaceans, and tiny water animals.

当蝌蚪孵的时候，它向后地被继续父母的中一个到父母喂它小的昆虫，蚂蚁，蜘蛛，甲壳类和极小的水动物的 bromeliad 。

The results indicate : The median lethal concentrations to the tadpoles are 13.24 mg/L in 15 ℃ and 9.85 mg/L in 20 ℃ respectively,and the confidence limit of 95% is 12.30～14.24 and 9.18～10.57 mg/L respectively.

结果表明：在15℃和20℃条件下，三氯杀螨醇对蝌蚪的LC50分别为13.24 mg/L和9.85 mg/L，其95%可信限范围分别为12.30~14.24 mg/L和9.18~10.57 mg/L
