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.

Based on the previous literatures, the following major innovation works were carried out in this dissertation:(1) The derivatization reaction conditions of ephedrine and pseudoephedrine with sensitive derivation reagent in aqueous system were studied and two new methods were developed for the assay of them by microemulsion electrokinetic chromatography and micellar electrokinetic chromatography with LIF detection. The sensitivity and analysis times were greatly improved compared with the previous reports;(2) A new method of CZE with indirect LIF detection was developed for the simultaneous determination of six coumarin compounds (esculin, esculetin, isofraxidin, genistein, naringin and sophoricoside) with fluorescein as the probe. The proposed method enlarges the application range of LIF detector, and provides new approach for the analysis of certain compounds difficult to derivatize;(3) Based on the above research, an MEKC with indirect LIF detection method for the simultaneous determination of adenine and guanine in DNA extracts from fungus, maize and soybean was established;(4) A new method for the investigation of the complexes formed between human serum albumin and ampicillin sodium under the simulated physiology conditions using laser light scattering technique was developed.

The oxidation mechanism of synephrine was also investigated;(2) The electrochemical behavior of twelve flavonoids (quercetin, morin, fisetin, luteolin, isorhamnetin, myricetin, hyperoside, quercitrin, puerarin, farrerol, naringenin and hesperidin) was investigated. The method for the determination of flavonoids was developed by using different pulse voltammetry, and the detection limit was in the range of 10-7~10-9 mol/L. This method has been successfully employed to determine the total amount of flavonoids in pericarpium citri reticulatae and quercetin in the spiked human blood plasma samples.

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.

Important advance was made to Celastrus and ceangulin V after 20 years studies, but the target of Celangulin V was not verified and the metabolic dynamic of Celangulin V in organism was not touched because of the technique difficulty in testing and analysis of trace Celangulin V in organism. It will solve the difficulty that establishing the immunoassay of Celangulin V. The immunoassay of Celangulin V including the synthesis of artificial antigen, the preparation of antiserum, the immunoanalysis location of Celangulin V and the quantitative immunoassay of Celangulin V were studied systematicly in this paper.
