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.

Results The tinnitus frequency, severity of subjective tinnitus, audiogram types and some items of function test above hearing threshold were significantly different in the five groups (P.05). Specific features of pure-tone test were found in the five groups: tinnitus frequency was low, whole- frequency hearing threshold high, audiogram even, short increment sensitivity index at 1 kHz high and tone decline at 4 kHz low in the syndrome of invasion of wind-heat; tinnitus frequency was high, high-frequency hearing loss common, audiogram abruptly descending, SISI and TD at 4 kHz high in the syndrome of liver-fire up-stirring; subjective tinnitus was loud, audiogram abruptly descending or gradually descending, SISI and 7W at 4 kHz low in the syndrome of stagnation of phlegm-fire; tinnitus frequency was high, subjective tinnitus low, audiogram markedly descending or hill-like, SISI and TD at 4 kHz high in the syndrome of kidney-essence deficiency; average hearing loss was less, audiogram irregular but abruptly descending or notched in most cases, SISI at 4 kHz low in the syndrome of weakness of spleen-stomach.

结果］耳鸣频率、自觉耳鸣程度、听力图类型及部分阈上功能测试指标在各证型间具有显著性差异(P.05)，这些指标在不同的证型中表现出不同的特点：风热侵袭型的耳鸣频率较低，全频听阈升高，听力图多为平坦型，短增量敏感指数得分在1kHz较高，而4kHz音衰值较低；肝火上扰型的耳鸣频率较高，听力损失以高频为主，听力图多为陡降型，4kHz SISI得分及TD值均较高；痰火郁结型的自觉耳鸣响度较大，听力图以陡降型或缓降型为主，4kHz SISI得分及TD值均较低；肾精亏损型的耳鸣频率较高，而自觉耳鸣响度较低，听力图以显降型或山型为主，4kHz SISI得分及TD值均较高；脾胃虚弱型的平均听力损失较小，听力图无一定规律性，但以陡降型或切迹型为主，4kHz SISI得分较低。
