环丙沙星与氧氟沙星注射液治疗细菌性感染的疗效观察

以乳酸环丙沙星（ＣＰＬＸ）注射液和氧氟沙星（ＯＦＬＸ）注射液随机分组治疗各种细菌性感染４０例及４２例，并以注射用头孢噻肟钠（ＣＴＸ）治疗４９例作对照。三组平均年龄、体重、疗程及病情程度相比无显著性差异，具可比性。病种分布以消化道感染最多，共８１例，占总数的６１．８％。三组１３１例病人细菌阳性率为９４．７％。一疗程ＣＰＬＸ组、ＯＦＬＸ组、ＣＴＸ组治愈率分别为８７．２％、８３．３％、７１．４％，有效率     

应用荧光免疫法检测生殖道沙眼衣原体及加德纳细菌

应用标记荧光素的抗沙眼衣原体(Chlamydia trachomatis,Ct)和抗阴道加德纳细菌(Gardnerella Vaginalis,GV)单克隆抗体,直接免疫荧光法(DFA)检测66例妇女生殖道标本。结果显示:Ct感染率为12.12％,GV感染率为19.70％。在妇科门诊患者Ct和GV感染率较高,应引起高度重视,18～40岁妇女是重点防治对象。     

两种后牙根管预备方法的临床效果比较

目的 :评估 2种后牙根管预备方法的临床效果。方法 :采用机用镍钛扩大锉 (ProFile)和手用不锈钢扩大锉 (K file)扩大后牙根管 ,并对 2组病例术后疼痛以及充填情况加以比较。结果 :发现机用镍钛扩大锉扩大后牙根管 ,具有去除根管感染物质彻底 ,根管形态保持良好 ,速度快 ,术后疼痛率较低的优点 ,但易出现断针。而手用不锈钢扩大锉扩大后牙根管速度较慢 ,术后疼痛率略高 ,但不易出现断针 ,操作上容易掌握。结论 :2种后牙根管方法都有优缺点 ,可结合起来使用。     

感染性心内膜炎手术时机的初步探讨

本文报道了15例感染性心内膜炎（IE）的外科治疗结果。左心IE9例，其中3例合并风湿性心脏病。右心IE6例，均合并先天性室间隔缺损（VSD）。活动性IE13例，静止期IE2例。右心IE的手术方法是修补VSD，剥除三尖瓣上的赘生物并涂以0.5％活力碘，环缩三尖瓣环。左心IE的处理方法为瓣膜置换。手术死亡2例。本文着重对手术时机进行了讨论。     

Experimental studies on preventive effects of API0134 on vessel reocclusion after thrombolysis

Summary 24 model rabbits with femoral arterial thrombosis were divided into two grocps: the treatment group consisting of 12 rabbits which received API₀₁₃₄. and the control group composed of another 12 rabbits. 2 hours after recanalization by urokinase thrombolysis, reocilusion occurred only in 1/12 vessel (8%) with incomplete occlusion in the treated group, but in 8/12 (67%) with complete occlusion in the control group as assessed by angiograsphy. Pathological examination of specimen taken 24 hours after thrombolysis showed that 6/12 (50%) of the treated group gave the evidence of thrombus occlusion, and milder intimai injury and less adhered blood cells than in the control group, 83% of which had thrombus occlusion. In comparision with the control group, the function of platelet in the treated group demonstrated lower platelet aggregation rate (PAgR) and plasma thromboxane A₂ (TXA₂) level, higher prostacyclin (PGI₂) and plasminogen activator (PA) activity as well as lower plasminogen activator inhibitor (PAI) activity. From the above it may be concluded that the preventive effect of API₀₁₃₄ on reocclusion might be due to inhibition of platelets aggregation and promotion of fibrinolysis.

国产4环／7层PET仪初试

对我国１９９６年研制成功的４环／７层ＰＥＴ仪（轴向视野８ｃｍ）进行试用。先进行模型试验和动物实验，然后对１例正常志愿者和７例患者进行１８Ｆ脱氧葡萄糖（ＦＤＧ）ＰＥＴ显像。静脉注射１８ＦＦＤＧ３７０ＭＢｑ后约１５小时显像，成人全身显像行１１个床位采集，约１５小时，心脑局部显像行２～３个床位采集，约半小时。直径１～３ｃｍ的阴模和阳模皆可显示。８例全身冠状和矢状断层影像清晰，正常志愿者（正常进食）可见脑和心肌显影，膀胱内放射性较多。２例恶性肿瘤患者的６处病变浓聚１８ＦＦＤＧ。２例恶性肿瘤患者手术和化疗后无复发征，显像阴性。２例良性病变处未见１８ＦＦＤＧ浓集。１例陈旧性心肌梗塞患者１８ＦＦＤＧ心肌断层显像与９９ｍＴｃ甲氧基异丁基异腈心肌血流灌注显像匹配良好。正常心肌显影与否受葡萄糖负荷的影响。８例脑皮质横断影像良好，基底节和丘脑影像有时尚欠清晰。初试结果表明，该ＰＥＴ仪相当于至今尚在国外广泛使用的８０年代中期４环／７层ＰＥＴ仪水平，但具有９０年代ＰＥＴ仪全身整体冠状和矢状断层显像的功能，可用于全身肿瘤显像、心肌活性判断和功能性癫痫灶术前定位，但仪器操作性能和软件功能尚需进一步完善。
