B超诊断前尿道损伤和狭窄21例报告

Ｂ超诊断前尿道损伤和狭窄２１例报告钱抚生，郭迎芬，刘秀卿，王舒，刘思阳，汪亚鑫自１９９２年３月以来采用超声下尿道内逆行注水，经阴茎、会阴部扫描的方法诊断前尿道病变，并将超声所见与尿道造影和手术结果进行对照，证实超声检查效果可靠。报告如下。资料与方法本...     

心肌造影超声心动图评估心肌缺血程度的实验研究

本实验制作不同程度心肌缺血的动物模型，以声处理５％人血白蛋白为超声造影剂进行心肌灌注造影，探讨ＭＣＥ时间－强度曲线各指标与心肌缺血程度间的关系。结果表明：心肌显影的峰值强度和曲线下面积均与缺血程度呈显著负相关（相关系数分别为ｒ＝－０．９８，Ｐ值＜０．００５；ｒ＝－０．９４，Ｐ值＜０．０５），且能区分轻度、中度和重度三种程度的心肌缺血；而三项时间指标与心肌缺血程度间未发现显著性差异。本实验的初步结果表明，ＭＣＥ是一项活体评估局部心肌血流灌注的有效方法。

生物样品中吡喹酮的测定方法

吡喹嗣(Praziquantel,简称PZQ)是近年研制由WHO推荐的一种广谱抗蠕虫病新药。其突出特点为疗效高,毒性低,服用简便;不仅对体内外各种血吸虫、华支睾吸虫、肺吸虫和肠绦虫等有显著杀虫活性,而且对脑囊虫病和棘球蚴(包虫)病亦有一定疗效。研究表明,作为PZQ靶体的上述各种寄生虫寄居于人体宿主的不同脏器和体液中,而到达这些部位的PZQ含量高低直接影响着临床疗效。因此,测定PZQ在体内各种体液和组织中的含量,不仅仅是PZQ药代动力学     

眼眶内木质异物漏诊探讨

眼眶内木质异物比较少见，诊断困难，漏诊、误诊率高，给病人带来极大痛苦。探索其有效的诊断方法至关重要。现就我院1986～1995年收治的14例（1只眼）漏诊、误诊病例作回顾性研究，并对诊断加以探讨。1临床资料1．1一般情况14例中，男11例，女3例；右眼6例，左眼8例；年龄最小

Electro-oculogram of Retinal Vein Occlusion

Twenty five cases, including 26 eyes with retinal vein occlusion (RVO) were examined by means of the electro-oculogram. The results showed that 23 of the 26 eyes suffering from RVO exhibited abnormalities of the electro-oculogram (EOG). The potential difference and Arden ratio in the RVO eyes were lower than those in the normal eyes (P<0.01). The more the visual acuity of ill eyes was decreased, the higher the abnormal rate of EOG in ill eyes was. 14 eyes had the visual acuity less than 0.1, whose EOGs were abnortmal. Six eyes had the visual acuity from 0. 2 to 0. 4, in which the EOGs of 5 eyes were abnormal. Six eyes had the visual acuity more than 0. 5, a-mong which the EOGs of 4 eyes were abnormal. Based on the above observations, it may be considered that the circulatory disturbance resulting from RVO damages not only the internal layer but also the external layer of the retina. We suggest that EOG is a useful method for distingquishing lesions caused by RVO and may reflect the functional condition     

用针剂瓶塞自制橡皮轮

取针剂青、链霉素的小瓶(其它针剂的小瓶也可),剥去铝盖,拔下橡皮瓶塞,并洗净擦干。用 5号长球钻或长裂钻(直径1.6mm)将瓶塞的圆心部位打穿,使成一小孔。旋下夹石针(夹轴)顶端的小螺丝(直径1.8mm),将其穿过瓶塞圆心部小孔,并旋紧在夹石针上。将夹石针柄插入电机直车
