采用多中心、随机、单盲、组间、平行对照的方法对488例原发性高血压患者进行氨氯地平或尼群地平4周治疗观察，显示氨氯地平的降压有效率为90．4％，较尼群地平显著为高。不良反应较少，安全性好。每日只需服药1次，剂量5～10mg，方便病人。     

用DNAG C含量和DNA同源性测定法鉴定米克戴德军团菌

本文采用热变性温度法和液相复性速率法对—轻型特征及血清学反应相似米克戴德军团菌(Lm)的菌株进行了测定,结果表明该菌与标准Lm(C DC株)的DNA G Cmol％相差3.45％,与标准Lm(C DC株)的DNA同源性达81.99％,根据伯杰细菌鉴定手册(1984),可判定该菌株与标准Lm(C DC株)为遗传型一致的类群,即从遗传学角度证明该菌为Lm。     

Additive effects of earthworm extract with HpD-laser on the enhancement of reactive oxygen production and the inhibition of[~3H]—thymidine.uptake in mouse ascitic tumor cells

The effects of combined use of earthworm extract(912)and HpD-laser on the produc-tion of reactive oxygen and the biosynthesis of DNA in S_(180) tumor cells were studied throughchemiluminescence measurement and[~3H]-TdR incorporation assay.The results showed that as com-pared with the control,the intensity of chemiluminescence emitted by tumor cells treatedsimultaneously with 912 and HpD-laser was enhanced more than ten-folds,while that treated with912 or HpD-laser alone was increased only 2～4 folds.The[~3H]-TdR incorporation into tumorcells of the former group was inhibited upto 74.1%,and that of the latter groups decreased onlyby 42.2% and 40.0%,respectively.In accordance with these biochemical changes,the ultrastructuraldamage of tumor cells of the former,combinedly treated group appeared to be the most serious.This suggests an additive effect of 912 with HpD-laser on tumor cells.In addition,if free radicalscavengers,such as catalase and superoxide dismutase,were added to the reaction systembefore chemiluminescence assay,the luminescent enhancement effect mentioned above was dramaticallyalleviated,implying the presence of O_2~ and H_2O_2 in the system.Therefore,as to the toxic effecton tumor cells,912 and HpD-laser are not only additive in efficiency,but also similar in theunderlying mechanism of action.     

对医院药事管理委员会系统工程管理的初探

本文通过对医院药事管理委员会的组织形式以及在医院药学事业中的特殊地位、工作任务、工作职责及职能效应的初步探讨,指出医院药事管理委员会在发展和建设医院药学事业中具有十三种职能、七大效应。认为加强医院药事管理委员会建设,是发展医院药学事业和保证医院药品质量的一种好方式。     

肾移植受者血清巨细胞病毒IgE和IgA抗体检测

采用间接ＥＬＩＳＡ检测２３名肾移植受者血清巨细胞病毒（ＣＭＶ）抗体，共检出１８名（７８％）活动性ＣＭＶ感染，其中１０名（４４％）为原发性感染。结果证实ＣＭＶ－ＩｇＥ和－ＩｇＡ具有较好的血清学诊断价值，优于ＣＭＶ－ＩｇＭ。

3，4－二羟基苯乙酮对家兔缺血－再灌心肌的影响

以超微结构、线粒体形态计量及ＬＤＨ，ＳＯＤ活性为依据，探讨３，４－二羟基苯乙酮（ＤＨＡＰ）对家兔缺血－再灌心肌细胞的影响。结果表明：ＤＨＡＰ组缺血－再灌心肌细胞的损伤、ＬＤＨ丢失及ＳＯＤ活性下降的程度均明显低于未用药组。提示该药物对缺血－再灌心肌有保护作用。     

In vitro histoculture of human tumors with fluorescent dye end-points measured by confocal microscopy: high correlation of in vitro and in vivo chemosensitivity.

Tumors from 40 patients and 7 established human xenograft tumor lines were grown in three-dimensional histoculture. A Viable-Cell-Index (VCI) based on fluorescent dyes and Growth Fraction Index (GFI) based on [3H]thymidine incorporation were measured by confocal microscopy and histological autoradiography, respectively, after treatment with cytotoxic agents. Chemosensitivity in vitro with the two methods was correlated with chemosensitivity of the same set of human xenografted tumor lines grown in nude mice. The percent accuracy of in vitro to in vivo correlation with VCI (73%) was higher than GFI (63%). The number of false positives with VCI was 12.1% (4/33), and with GFI was 31.3% (10/32). The results thus indicated that in vitro histoculture with fluorescent vital-dye end-points to measure cell viability is of potential use to determine tumor chemosensitivity.     

128对不育夫妇血清、精浆抗精浆免疫抑制物抗体与精液检查关系的分析

我们检测了８９对生育夫妇和１２８对不育夫妇血清、精浆中抗精浆免疫抑制物抗体（ＳＰＩ—Ａｂ）的水平。结果表明，不育夫妇血清、精浆ＳＰＩＭ—Ａｂ的水平和检出率均明显高于生育组（Ｐ＜０．０１）；精浆ＳＰＩＭ—Ａｂ水平增高者的精子密度、精子活率、精子运动速度和ＳＰＩＭ活性均明显降低（Ｐ＜０．０１）。提示：ＳＰＩＭ—Ａｂ水平增加可能影响生育。
