In pH value 6.40 Clark-Lubs buffer solution, the fluorescence intensity of safranine T and sodium dodecyl benzene sulfonatewas determined. After adding organophosphorus pesticides, the fluorescence intensity was determined. Based on this, a new fast and simple method for determination of the organophosphorus pesticides total-residues was developed.

It is based on the facts that in the presence of sulfuric acid and sodium dodecyl benzene sulfonate, vanadium activated by vitamin C can catalyze potassium bromate to oxidize safranine O, the oxidation products of safranine O can emit intense and stable fluorescence on nitrocellulose membrane.

基于在硫酸介质和十二烷基苯磺酸钠存在下，抗坏血酸活化钒催化溴酸钾氧化番红花红O发射强而稳定的荧光的特性，建立了ⅤC活化溴酸钾氧化番红花红O催化荧光法测定痕量钒的新方法。

Methods Porcine bile duct and ureter were treated using detergent sodium dodecylsulphate and 1% Triton X-100 to prepare the acellular lumens matrix. The toxic effects of different concentrations of acellular lumens matrix extract were tested by MTT to assess the proliferation of human scarfskin fibroblasts. The cytotoxicity of the target biomaterial was graded according to the national standards. The growth manner of the human intrahepatic bile duct endothelial cells seeded on the acellular lumens matrix was studied after 20 d under scanning electron microscopy.
