中文摘要：两栖动物幼体变态过程是受甲状腺激素所精密调控的。对中国林蛙Rana chensinensis变态前期、临近变态期、变态高峰期和变态完成期的蝌蚪进行了外部形态指标(全长、体长、尾长和后肢长等)的测定，采用解剖和组织学方法对其甲状腺进行了组织学观察，并对蝌蚪外部形态指标与甲状腺形态机能之间的相关性进行了统计分析。结果显示，中国林蛙蝌蚪甲状腺分泌甲状腺激素机能活性的峰值出现于变态高峰期的前肢伸出期。统计分析表明，蝌蚪外部形态指标全长和后肢长的发育信息也可以反映其甲状腺分泌甲状腺激素的机能活性。
英文摘要：The amphibian larval metamorphosis was accurately regulated by thyroid hormone. The external morphological indices such as the total length, body length, tail length and hind limb length of Rana chensinensis tadpoles at the different stages (pre-metamorphosis, pro-metamorphosis, metamorphosis and post-metamorphosis) were measured. Subsequently, the histological structures of thyroid glands in tadpoles were observed under light microscope. In addition, the correlation analysis between functional characters of thyroid glands and morphological features of tadpoles were analyzed by the SPSS software. The results showed that the activity of thyroid glands reach its peak when the tadpole forelimb emerged. The developmental data such as body length and hind limb length of R. chensinensis tadpole could reflect the activity of thyroid gland during metamorphosis.

这个研究有点意思。我觉得更好的应该是测定一下甲状腺激素的含量。
