The transfer behavior of pyrazolone derivatives, such as antipyrine, aminopyrine, 4-aminoantipyrine and analgin, across the W/NB interface was investigated. The three medicines studied can form complex with a proton and the complex formed can transfer reversely across the W/NB interface and the transfer process was controlled by diffusion. The transfer of protonated analgin was not observed within potential window because of its high transfer potential.

研究了吡唑啉酮类的安替比林、氨基比林、4-氨基安替比林和安乃近四种药物在W/NB界面的转移行为，前三种药物在一定pH值的水溶液中结合一个质子形成1∶1质子配合物，并能在W/NB界面发生可逆转移，其转移过程受扩散控制，安乃近的质子化物由于有较高的转移电位而未在电位窗内观察到其转移峰。

Here we show that VacA permeabilizes the apical membrane of gastric parietal cells and induces hypochlorhydria.The functional consequences of VacA infection on parietal cell physiology were studied using freshly isolated rabbit gastric glands and cultured parietal cells.Secretory activity of parietal cells was judged by aminopyrine uptake assay and confocal microscopic examination.

为此，我们建立了原代培养的胃腺、胃壁细胞等研究模型和良好的评估壁细胞分泌能力的技术平台，包括氨基比林吸收实验、激光共聚焦扫描技术等，对VacA感染所导致的壁细胞生理特征的改变进行了深入细致的研究。

In order to study the relation of cytochrome P-450 with the protective action of SY-801 and SY-640 against 〓-induced UDS and 3H-BP binding to nuclear DNA, the effects of SY-801 and SY-640 on liver microsomal cytochrome P-450 were studied in mice. The results indicated that the liver microsomal cytochrome P-450 concentration and aminopyrine demethylase activity were significantly increased in mice pretreated with SY-801 150mg/kg or SY-640 150 mg/kg once daily for three days.

本实验进而观察了SY-801对小鼠肝微粒体细胞色素P-450酶系的影响，结果表明SY-801和SY-640体内连续给药3天，可诱导小鼠肝微粒体细胞色素P-450含量明显增加，同时氨基比林脱甲基酶活性亦明显增加；给药1次2小时内二者均可抑制氨基比林脱甲基酶活性，而对肝微粒体细胞色素P-450含量则无明显影响。

Activities of Aminopyrine N-demethylase, Ethoxycoumarin O-deethylase and Glutathione S-transferase in the hepatopancreas and gills of Fenneropenaeus chinensis were measured by UV spectrophotometry and fluorospectrophotometry. The effects on the activities of APND and ECOD、GST in the hepatopancreas and gills were studied following multi-oral baicalin.

用紫外分光光度法及荧光分光光度法测定中国对虾肝胰腺及鳃氨基比林－N-脱甲基酶、乙氧基香豆素－O-脱乙基酶、谷光甘肽－S-转移酶几种药物代谢酶的活性，探讨黄芩苷对上述几种酶活性的影响。
