Mdr1 express product p - glycoprotein was detected by immunocytochemical method and flowcytometry. the cytotoxicity and multidrug resistance reversion effect of tea polyphenol was examined by mtt assay in mcf - 7 and mcf - 7 adr carcinoma cell lines, and compared with pgp inhibitor quinidine. the pgp expression of mcf - 7 adr was strongly positive, the positive rate was 15 % ; the pgp expression of mcf - 7 was negative, the positive rate was 1. 8 %. ic50 of tea polyphenol to mcf - 7 and mcf - 7 adr is 115. 2g ml and 207. 6g ml respectively. ic50 of quinidine to mcf - 7 and mcf - 7 adr is 129. 8mol l 42. 1g ml and 94. 1mol l 30. 5g ml respectively. tea polyphenol and quinidine changed little toxicity of adriamycin to mcf - 7, but tea polyphenol and quinidine improved the sensitivity of mcf - 7adr to adriamycin significantly. immunocytochemistry and flow cytometry can detect p - glycoprotein expression level qualitatively and quantitatively. tea polyphenol is not only an anti - tumor agent, but also a multidrug resistant modulator similar as quinidine. tea polyphenol is advantageous for its little toxicity in tumor treatment
用免疫組化法和流式細胞儀對腫瘤細胞系mcf - 7和mcf - 7 adr的p -糖蛋白表達水平進行定性定量研究。用噻唑藍比色法mtt研究茶多酚的細胞毒性及其對耐藥性的逆轉作用,並與pgp抑制劑奎尼定進行了比較。免疫組化法檢測p -糖蛋白表達水平, mcf - 7 adr呈強陽性,而mcf - 7呈陰性流式細胞儀定量檢測結果mcf - 7 adr細胞系細胞陽性率為15 % , mcf - 7細胞系細胞陽性率為1 . 8 % 。In order to compare the retention time ( rt ) and limits of detection of 20 organophosphorous insecticides in different conditions the experiments were carried out using a medium polar capillary column ( db - 1701 ) and a no polar capillary column ( db - 1 ) with two detectors ( gc - fpd and npd ). the rt of 20 organophosphorous insecticides in two different polar capillary columns was a retention qualitative method for 20 organophosphorous insecticides. db - 1701 capillary column coupled with gc - fpd detector was used in the following study, the limits of detection were in range of 5x10 - 11 ~ 2x 10 - 12 g, the linear range was 2x 10 - 9 ~ 1 x 10 - 11g
本研究用兩種檢測器(氮磷檢測器和火焰光度檢測器儀器)和兩種不同極性色譜梓(中極性毛細管色譜柱db - 1701 、非極性毛細管色譜柱db - 1 )作為研究手段,比較了20種有機磷殺蟲劑在兩種色譜柱( db - 1 、 db - 1701 ) 、兩種檢測器( fpd 、 npd )上的保留時間及最小檢測量,建立了用不同極性色譜柱上有機磷農藥的保留時間可作為有機磷農藥雙柱定性確證的的方法;建立了db - 1701 , gc - fpd測定蔬菜中20種有機磷殺蟲劑的氣相色譜法,該方法的最小檢測量為5 10 ~ ( - 11 ) 2 10 ~ ( - 12 ) g ,線性范圍在2 10 ~ ( - 9 ) 1 10 ~ ( - 11 ) g時,相關性良好。Zbd model whiteness measurement meter is mainly applicable to measurement of the whiteness of colourless even surface objects and powder, such as paper, pulp, ceramics, enamel, plastics, enamel, plastics, various fiber and fabric, wheat flour, talcum powed, starch, coating and chemicals etc. it canalso measure comparatively accurately the fluorescent whiteness of the objects with fluorescentbrighterner
Zbd型白度測定儀主要用於測量非彩色表面平整的物體及粉末的?白度? ,如紙張,紙漿,陶瓷,搪瓷,塑料,個種織維及其織品,麵粉,滑石粉,澱粉,塗料及化工產品等,對于添加熒光增白劑的物品,本機也能比較準確的測量其?熒光白度? 。
