成人支原体肺炎病原检测与临床分析

肺炎支原体（MP）在呼吸道感染中越来越受到重视，MP肺炎占各年龄组发病的10～20％[1]，而且是成人慢阻肺急性发作的重要病原之一[2]。由于本病缺乏特异临床表现，确诊依靠病原或抗体的检测。病原分离培养固然可靠，但无助于早期诊断[3]。抗体测定，仅能证明血清中有无MP抗体，恢复期抗体滴度升高四倍，虽有诊断意义，但已失去早期诊断价值。近年来国内外开展了聚合酶链反应（PCR）技术检测MP，此法快速，可靠、特异性高，成为MP感染早期特异诊断的有力武器[4，5]。PCR技术检测成人肺炎研究尚少，我们在1993年8月～12月对住院50例肺…     

2—对—（二甲氨基）苯乙烯碘化甲基吡啶对缺血心肌的保护及抗氧化作用

小鼠ip 2-[对－（二甲氨基）苯乙烯]碘化甲基吡啶（DSPM），3h后sc异丙肾上腺素（Iso)20mg.kg^-1每日一次，共2d，发现DSPM 1，3mg.kg^-1能抑制Iso所致的心肌Se-GSH-PX活性降低和MDA生成，3mg.kg^-1能减轻SOD活性的降低，上述指标与心肌超微结构和血清CPK浓度的变化基本一致，提示DSPM可能通过抑制O2- 的产生及其脂质过氧化反应而发挥心肌保护作用。     

Ultrasound Biomicroscopic Dark Room Provocative Test

Purpose : To compare the clinical application value of Ultrasound biomicrsocpic dark room provocative test with the traditional dark room test in screening primary angle closure glaucoma (PACG).Methods: 22 eyes with PACG in prodromal stage and 30 eyes with deep anterior chamber and wide angle of 15 normal persons were observed in this trail. All 52 eyes were performed traditional dark room provocative test and ultrasound biomicorosopic darkroom test respectively. With different positive diagnostic criteria, the sensitivity of the two methods were compared using chi-squared analysis.Results : After staying in the dark room for 2 hours, In case group, IOP in 10 of 22 eyes rose more than 1. 07kPa(1kPa = 7.5mmHg), in 12 eyes less than 1.07kPa or had no changes; appositional angle closure were found by Goldmann gonioscopy in 8 eyes : 3 eyes in two quadrants, 5 eyes in more than two quadrants; the appositional angle closure was found by UBM in 15 eyes; 3 eyes in one quadrants, 5 eyes in two quadrants, 7 eyes     

奥丹西酮在原发性肝癌患者的药物动力学

目的 观察奥丹西酮在原发性肝癌患体内的药物动力学特性。方法 8名接受顺铂＋5－氟尿嘧啶化疗的原发性肝癌患单次和多次口服16mg奥丹西酮后，应用反相高效液相色谱法测定血浆药物浓度，并用PKBP－N1程序在计算机上拟合。结果 奥丹西酮表现为二房室模型，其单剂量和多剂量口服主要药动学参数分别为：T1／2β为4.3±0.5h和5.7±0.7h(P<0.01),Cmax为42．6±3.8μg/L和49．2±2.3μg/L(P<0.05),Tmax为1．8±0.2h和1.8±0.1h,AUC0-∞为643．2±84.7μg/h·L和833．4±96.7μg/L·h(P<0.01)。结论 原发性肝癌患多次口服奥丹西酮后与单次口服相比，体内有蓄积现象，消除能力下降，生物利用度升高。
