RELATION OF PERIOPERATIVE SERUM THYROID HORMONE CHANGES TO HEART DYSFUNCTION IN PATIENTS UNDERGONE CARDIAC VALVE REPLACEMENT

Myocardial dysfunction is commonly a signifi-cantproblem following heart surgery.Recentstud-ies demonstrated that decreased serum triiodothy-ronine(T3) concentration probably plays an impor-tantrole in the pathogenesis ofboth critical chroniccongestive heart failure and low cardiac output af-ter heart surgery[1,2 ] .To further explore the rela-tionship of perioperative thyroid hormone changesto heart dysfunction,the serum concentration ofthyroid hormone in2 0 patients undergoing mitralvalve re…     

脑出血致多脏器功能失常综合征的多因素相关分析

探讨多脏器功能失常综合征（Multipleorgandysfunctionsyndrome，MODS）的病因及高危因素。对229例老年脑出血患者进行了回顾性调查，其中MODS患者97例，与132例无MODS的脑出血患者的临床资料比较，结果表明：原发病的危重程度和全身炎症反应综合征（Systemicinflammatoryresponsesyndrome，SIRS）与MODS的发生密切相关（P＜0．01）。MODS的高危因素的单因素分析均有统计意义（P＜0．05）。作者认为除了脑出血本身的严重程度外，治疗不当、老年患者并存躯体疾病也是激发SIRS和MODS的重要因素。

RIGOROUS PROOF FOR CHARACTERISTICS OF PRACTICABLE MAGNETIC POTENTIOMETERS AND THEIR APPLICATION

IntroductionThe magnetic potentiometer or Rogowski coilhas been widely applied for measuring the heavyAC- current and pulsed current[1～ 3 ] . It has variousadvantages among which the following are of vitalimportance:1 The relation between the inducedoutput voltage in secondary winding and the differ-ential of the primary currents is exactly linear;2The output voltage is independent of the positionof the primary circuit;3 The outputvoltage is un-affected by stray fields of the current which …     

硒对人体白细胞氧化活性的影响——人全血化学发光法及其应用

本文首次采用改良的人全血化学发光法检测了不同浓度硒对10例健康成人白细胞氧化活性的直接影响。将四种不同浓度硒分别加入健康成人新鲜抗凝全血中,使其最终浓度分别为0.001μg/ml、0.01μg/ml、0.1μg/ml和1μg/ml,4℃冰箱储存,并于1小时、12小时和36小时进行化学发光的动力学测量,其结果与加硒前相比,化学发光峰值和60分积分值均无明显差异(P>0.05)。表明在此预防浓度范围内,亚硒酸钠对吞噬细胞的氧化活性无直接地激发或抑制作用。此为临床补硒及阐明作用机理提供参考依据。     

洛美沙星葡萄糖注射液的药效学研究

报道了洛美沙星葡萄糖注射液的体内、体外抗菌活性，并与其口服制剂及环丙沙星注射液进行了比较。结果表明：洛美沙星注射液是一种广谱、高效、作用迅速的抗菌药物，对革兰氏阳性茵的MIC为0．31～20mg／L，对革兰氏阴性菌的MIC为0．005～10mg／L。杀菌实验表明：对金葡菌、大肠杆菌、痢疾杆菌、肺炎杆菌及绿脓杆菌为杀菌作用。抗菌效果基本不受PH、接种菌量和血清蛋白结合的影响。体内效果（ED50）优于口服制剂。体内、外抗菌活性近似于环丙沙星。

血管瘤和脉管畸形内皮细胞增生的研究

采用４级分类法对３７８例脉管病变内皮细胞增生程度进行了分级，其中５４例作了ＡｇＮＯＲ和肥大细胞计数。结果：血管瘤内皮细胞增生为Ⅱ、Ⅲ级，而脉管畸形组内皮细胞增生为Ｏ或Ｉ级。ＡｇＮＯＲ和肥大细胞计数，血管瘤明显高于脉管畸形组，表明血管瘤和脉管畸形是性质不同的两种病变。本文还总结了血管瘤和脉管畸形的病变特征和鉴别要点，以利于诊断、治疗和进一步的研究。
