高寒地区短期军训人员适应能力的观察

1985年3月初,我们配合高原驻军某部进行了高寒缺氧条件下野外生存能力和作战能力的试验研究。试验人员随军训部队在不同海拔高度、气温、湿度等条件下检测了部分受试人员的心率、血压、心电图、脑血流图、血红蛋白、网织红细胞和尿液检查等项指标,并于训练前后在驻地附近医院(海拔3100米)进行了胸部X线拍片,以观察高寒低氧环境下从事军训对受试对象的心率、血压、心电图、脑血流图、血红蛋白、网织红

完全性左束支传导阻滞合并显著电轴左偏32例分析

本文对32例完全性左束支传导阻滞(CLBBB)合并显著电轴左偏超过(-30°)和20例CLBBB电轴正常两组病人进行对比观察。结果无论在心脏形态大小或心电图改变方面电轴左偏病人比电轴正常者病情严重。CLBBB合并电轴明显左偏的发病机制可以有五种情况解释。     

异氟醚全复吸入诱导麻醉

异氟醚是迄今最新和接近理想的吸入麻醉药。因其气味辛辣、刺激,多用作维持麻醉。Wren(1984)在小儿中用N_2O-O_2-异氟醚混合气体作吸入诱导获得成功。本文作者探索在成人中用国产103型麻醉机作异氟醚全复吸入诱导的可行性;并试图依靠临床常用体征判断麻醉深度和确定恰当的气管插管时机。今将有关方法、资料等分别介绍讨论如下:方法麻醉前用药包括苯巴比妥钠0.1g、安定10mg及     

Sinoatrial Node Electrogram Studies in Patients with Sick Sinus Syndrome

Sinoatrial node electrogram (SNE) was recorded successfully in recent years, using transvenous electrode catheter. Via SNE and intratrialelectrogram (IEG), one could measure sinoatrial conduction time(SACT) directly, observe sinoatrial node (SN) potential changes in cadiac cycles, diagnose some sinus arrhythmias which couldn't be confirmed by surface ECG. All these could offer accurate evidence for differential diagnosis of sick sinus syndrome (SSS). The authors recommend a modified method for the location of the electrode catheter, by which one can increase success rate of obtaining stable SNE. Using this method, the authors recorded SNE in 10 cases with SSS successfully.     

Effect of Some Thiol Chelators on Enzymatic Activities in Blood,Liver and Kidneys of Acute Arsenic（Ⅲ）Exposed Mice

The effects of meso 2,3-dimercaptosuccinic acid(DMSA),sodium 2,3-dimercaptopropane 1-sulfonate(DMPS)and S-adenosyl L-methionine(SAM)on the enzymatic acivities of mice were studied.The mice were given intraperitoneal(i.p.)injections of these chelating agents(1 mmol/kg) and 3 h later the activity of δ-aminolevulinic acid dehydratase(ALAD) in the blld,and aspartate aminotransferase(AST),alanine aminotransferase(ALT),γ-glutamyltranspeptidase(γ-GT）,alkaline phosphatase(ALP)in the liver and kidney were determined.The activity of blood ALAD was significantly increased by the administration of DMSA and SAM while DMPS had only a moderate effect.The activities of other hepatic enzymes changed little the mice were treated with these chelating agents,except for a significant reduction in hepatic ALP activity following DMPS administration.Arsenic(Ⅲ） administration markedly increased the activities of ALT and ALP in the liver and kidneys.The changes in the enzymatic activities by treatment with arsenic were prevented by injection of DMSA,DMPS and SAM,DMSA being the most effective.These results indicate that DMSA,DMPS and SAM wer not toxic to the liver or kidnys of mice and that treatment with DMSA is more effective than DMPS or SAM in protecting mice from acute hepatic or renal toxicity caused by arsenic.     

QT及JT离散度对心性猝死预测价值的探讨

测定３２例心性猝死和３０例非猝死性心性死亡病人入院后的首次心电图ＱＴ离散度（ＱＴｄ）和ＪＴ离散度（ＪＴｄ），产以３０例存活病人作对照，结果显示：（１）心性猝死组ＱＴｄ，ＪＴｄ较存活组和非猝死性心性死亡组显著增大（前者Ｐ均〈０．０１，后者Ｐ均〈０．０５，而非猝死性心性死亡组与存活组ＱＴｄ，ＪＴｄ比较差异均无统计学意义。（２）在心性猝死病人中，死亡直接原因为快速室性心律失常组（２３例）的ＱＴｄ，ＪＴｄ
