查询词典 adenine

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.

Methods: Rat models of chronic renal failure were made by cut 5/6 kindney or fed with feedingstuff which contains adenine(0.75%) for 4 weeks. Experimental treatment was applied by giving Yi Shen Granule and the curative effect of Yi Shen Granule on ongoing pathological changes of CRF was studied. According to the data of CRF rats in weight, water wastage, hemanalysis(RBC、HGB、HCT、MCV、MCH), urinalysis(volume, specific gravity, pH, proteinuria), blood serum analysis(BUN、Cre、ALB、TP), kidney weight coefficient and kidney morphology ( the grade of expansile renal tubule and the diameter of glomerulus ),the pharmacological effect of Yi Shen Granule could be ascertained.
