OBJECTIVE To discuss the effect of Zea mays L. saponin (ZMLS) on ultrastructure of kidney and pancreas in the diabetes rats induced by streptozocin. METHOD The diabetic rat model was established by injections of STZ, blood glucose, the ultrastructure of the kidney and pancreas were observed. RESULT Compared with the model group, the large, middle-dose(More)
2-(2'-hydroxyphenyl) benzimidazole (HBI) is one kind of organic molecule with excited-state proton transfer (ESPT) effect. The absorption spectra of HBI were observed in toluene, the mixture of toluene and ethanol, and ethanol, respectively. It was found that the absorption spectra in the three solvents are similar. The fluorescence of HBI was observed(More)
7-hydroxyquinoline (7-HQ) is a kind of organic molecule with excited-state proton transfer (ESPT) effect. 7-HQ in ethanol solution causes ESPT reaction under the excitation of ultraviolet light. The fluorescence spectrum of the sample exhibits two bands. In contrast, 7-HQ in dimethyl sulfoxide (DMS) solution does not cause ESPT reaction. The fluorescence(More)
The absorption and fluorescence spectra of 3-hydroxyflavone (3-HF) in different polar solvents were observed with UV-Vis spectrometer and fluorescence spectrometer, respectively. There are three absorption bands in the absorption spectra, wherein two absorption bands with absorption peak at 300 and 345 nm, respectively, are strong, and the other one with(More)
2-(2 -hydroxyphenyl)benzothiazole (HBT) is a typical compound with excited--state intramolecular proton transfer (ESIPT) effect. The mechanism of the influence of the solvent polarity on the ESIPT effect of HBT was investigated by means of absorption and fluorescence spectra in different polar solvents. The absorption spectra of HBT molecule in all solvents(More)
