川芎嗪对脑外伤患者血栓素、前列腺环素及颅内压的影响

28例重度脑外伤患者分为川药嗪治疗组和一般治疗对照组,两组病人均于用药前和用药后3小时测定血浆和脑室内脑脊液(VCSF)中血栓素代谢产物(TXB_2)前列腺环素代谢产物6—酮—PGF_(la)(6KP)和颅内压。结果表明:两组治疗前血浆、VCSF中TXB_2及T/K均明显高于正常献血员对照组,川芎嗪能降低脑外伤患者血浆、VCSF中TXB_2及T/K值,对颅内压则无明显影响。提示川芎嗪能抑制脑外伤对血小板的激活、纠正循环血中TXA_2—PGI_2平衡失调,从而改善脑微循环。     

鸟氨酸-天门冬氨酸联合乳果糖治疗肝性脑病疗效观察

目的探讨鸟氨酸-天门冬氨酸(雅博司)联合乳果糖治疗肝性脑病的疗效.方法选择56例肝性脑病患者,在综合性治疗的基础上,给鸟氨酸-天门冬氨酸20g/d静脉滴注;乳果糖20ml口服或鼻饲,每日三次.另选36例患者作为对照组,给一般综合性治疗,同时给乙酰谷酰胺1.0g/d静脉滴注,分别治疗20天.结果治疗组病死率明显下降,与对照组相比,有显著性差异(x2=4.02,P＜0.05),在降低血氨及促进脑电图改善方面,两组也存在显著性差异.结论雅博司联合乳果糖治疗慢性重型肝炎合并的肝性脑病,疗效显著,值得研究和应用.     

Mandibular fracture not shown by axial computed tomography: Benefit of computed reformation

A 36-year-old man was brought to the emergency department after being assaulted. A mandible series showed a nondisplaced fracture through the angle of the mandible extending through the left third molar tooth. Axial slices from a nonhelical computed tomographic (CT) examination of the head as well as a helical CT examination of the mandible failed to demonstrate the fracture. The fracture was well shown, however, on sagittal CT reformations. Although CT is generally regarded as more sensitive than plain radiography for the detection of fractures, fractures may be overlooked by CT if examination in only one plane is performed.     

头低位限制活动对家兔主要脏器微血管壁通透性的影响

本文报导了用40只白色短毛家兔所做的动物模拟失重实验,得出各脏器微血管通透性的动态反应曲线。并用微循环研究方法,分析了模拟失重时各脏器微血管功能状态与微血管通透性之间的关系;阐述了各脏器微循环功能变化特点;并对变化机理作了初步探讨。     

Statistical analysis of the factors affecting the outcome of extradural haematomas: 115 Cases

Summary 115 traumatic extradural haematoma cases who were treated surgically at Cerrahpasa Medical Faculty Neurosurgery Department between 1987 and 1992 are evaluated.When factors affecting the outcome were examined, a strong correlation was found between the result andGlasgow coma scale (GCS) (p<0.00001). The existence of a fracture, the interval between onset of haematoma symptoms and intervention and the existence of an intracerebral haematoma together with contusion accompanying intradural haematoma, affect the outcome in a negative direction. There was no statistical correlation between the outcome and the age of patient, localization of the haematoma and aetiology.     

高压氧在治疗脊髓损伤伴截瘫及肢体慢性溃疡中的应用

本文报告了用高压氧治疗脊髓损伤伴截瘫患者１２例，肢体慢性溃疡８例。将患者置于２个大气压的单人氧舱内，每次９０ｍｉｎ。前者疗程为１周，每日２次。后者疗程为２周，每日１次。治疗结果：脊髓损伤伴截瘫患者中８例有明显而有意义的功能恢复，占６６．６％。慢性溃疡患者中有３例愈合，４例好转，有效率为８５％。作者认为：早期使用高压氧是治疗急性截瘫，尤其是不完全性截瘫的一种安全有效的方法。高压氧治疗可加速慢性溃疡创面的愈合，但不能取代溃疡面的局部处理。     

眼外伤临床统计规范探讨

眼外伤是我国眼科住院三大主要疾病之一，占眼科住院病人总数的１６￣３２％。每年发表临床统计文章百余篇，但由于统计资料不全面，标准不统一，降低了这部分劳动的价值。本文就眼外伤临床统计规范及某些问题进行讨论，强调规范化的重要意义。
