云南花粉田七口服液对全血中超氧化物歧化酶活性的影响的实验研究

本研究采用ＳＯＤ微量快速测定法，报道了云南花粉田七口服液（ＹｕｎＮａｎＰｏｌｅｎＴｉｅｎｃｈｉＯｒａｌＬｉｑｕｉｄ，简称ＹＮ－ＰＴＯＬ）对３０只（１２～１４）月龄的昆明种小白鼠红细胞中ＳＯＤ活性影响及其作用机制。研究结果表明，灌胃云南花粉田七口服液的试验组动物，其红细胞ＳＯＤ活性分别与对照组和空白组比较，其中试验组红细胞中ＳＯＤ活性（３２９．９０±５９．７６ｕ／ｍｌ）与相应对照组（２５９．９０±１２２．０８）ｕ／ｍｌ比较差别不明显（Ｐ＞０．０５），但与相应空白组（１５１．０６±６７．２２）ｕ／ｍｌ比较，差别却有显著性意义（Ｐ＜０．０００５）。这提示，在本疗程和试验剂量内，ＹＮ－ＰＴＯＬ能有效提高抗氧化酶ＳＯＤ活性，这不仅对老年动物体内氧化损伤具有防御作用，而且对机体的延年益寿具有重要意义。     

缺血－再灌注损伤与高空减压病

５例延迟性Ⅱ型高空减压病（ＤＣＳ）血铜锌超氧化物歧化酶（Ｃｕ－ＺｎＳＯＤ）测定结果，平均３１０．２ｎｇ／ｍｌ，较低者分别为２０５、２３１和２５０ｎｇ／ｍｌ。对照组平均３８５．６ｎｇ／ｍｌ，较低者分别为３３０、３４０和３６６ｎｇ／ｍｌ。经Ｘ２检验，患者组明显低于对照组（Ｔ＝６．１６５，Ｐ＜０．０１），治疗后１个月患者组血ＳＯＤ恢复正常。表明ＤＣＳ与缺血－再灌注损伤有一定联系．     

心肌顿抑时红细胞变形性变化机理及其意义初探

目的和方法：本文通过一次性阻断兔冠脉左室支１５ｍｉｎ后再灌注复制在体心肌顿抑（ＭＳ）模型，动态观察心肌缺血前后红细胞变形指数（ｄｅｆｏｒｍａｂｉｌｉｔｙｉｎｄｅｘ，ＤＩ）、红细胞超氧化物歧化酶（ｓｕｐｅｒｏｘｉｄｅｄｉｓｍｕｔａｓｅ，ＳＯＤ）活力、红细胞ＡＴＰ、红细胞丙二醛（ＭＤＡ）含量和心功能参数（左室舒张末压、左室收缩压±ｄｐ／ｄｔｍａｘ）变化。结果：缺血末心功能下降最显著（Ｐ＜００１）；再灌注０５ｈ时ＭＤＡ明显升高，而ＤＩ、ＳＯＤ明显下降（Ｐ＜００１）。随继续再灌注上述指标逐渐恢复。各时点ＡＴＰ无明显变化。再灌注０５ｈ时红细胞ＭＤＡ与ＤＩ、ＳＯＤ均呈显著负相关（Ｐ＜００１），ＤＩ与＋ｄｐ／ｄｔｍａｘ正相关（Ｐ＜００５）。结论：ＭＳ早期红细胞变形性降低与暂时性氧化－抗氧化失衡有关；再灌注早期红细胞变形性降低可能参与ＭＳ早期发生机制

本文采用双抗体夹心ＥＬＩＳＡ法分别测定了２１例反复呼吸道感染儿，３０例正常儿童，１０例新生儿脐血的血清可溶性白细胞介素２受体（ｓＩＬ＝２Ｒ）水平。结果患儿组ｓＩＬ－２Ｒ为７１６．６０±３０．１０Ｕ／ｍｌ；正常儿童组为３８４．４７±８８．０３Ｕ／ｍｌ（ｐ＜０．０１）；新生儿脐血为４４６．２０±５５．６８Ｕ／ｍｌ，与正常儿童比较Ｐ＞０．０５。同时采用间接免疫荧光技术测定了患儿Ｔ细胞亚群水平，结果ＣＤ８细胞数升高，ＣＤ３细胞和ＣＤ４细胞数、ＣＤ４／ＣＤ８比值下降，与正常儿童比较有显著性差别。提示反复呼吸道感染儿有细胞免疫功能降低及免疫调节紊乱。     

肌萎缩性脊髓侧索硬化症与铜锌超氧化物歧化酶之间关系的研究 …

肌萎缩性脊髓侧索硬化症（ａｍｙｏｔｒｏｐｈｉｃ ｌａｔｅｒａｌ ｓｃｌｅｒｏｓｉｓ,ＡＬＳ）是一种致命的神经退化性疾病,在ＡＬＳ所有的病例中有５％～１０％是家族性ＡＬＳ（ＦＡＬＳ）,它是一种常染色体显性遗传病,与２１号染色体上的ＳＯＤ－１基因（编码铜锌超氧化物歧化酶〈Ｃｕ／Ｚｎ－ＳＯＤ〉）的突变有关,但突变的Ｃｕ／Ｚｎ－ＳＯＤ酶功能障碍并不能直接损伤神经元而导致ＡＬＳ的发生。因为正常野生型Ｃｕ／Ｚ     

麻风病人血液超氧化物歧化酶的研究

用亚硝酸法测定各型麻风病（ｎ＝７３）及健康人（ｎ＝１５）血浆中ＳＯＤ总量、Ｍｎ－ＳＯＤ和Ｃｕ、Ｚｎ－ＳＯＤ含量；发现各型麻风病人血浆中ＳＯＤ总量和Ｍｎ－ＳＯＤ含量均比正常人高（Ｐ＜０．０１），而Ｃｕ、Ｚｎ－ＳＯＤ含量无显著性差异（Ｐ＞０．５）。提示麻风病人血浆中ＳＯＤ总量升高，受Ｍｎ－ＳＯＤ的影响；后者存在于细菌体内，从而证明麻风病人体内的ＳＯＤ主要来源于麻风分枝杆菌。     

应用ELISA和滴金免疫测定法检测血清肌红蛋白

从人心肌提取肌红蛋白（ｍｙｏｇｌｏｂｉｎ，Ｍｂ）抗原，制备抗Ｍｂ血清和单克隆抗体，在此基础上建立了检测血清Ｍｂ的ＥＬＩＳＡ和滴金免疫测定法（ｄｏｔｉｍｍｕｎｏｇｏｌｄｆｉｌｔｒａｔｉｏｎａｓｓａｙ，ＤＩＧＦＡ）。ＥＬＩＳＡ法检测范围２５～８００ｎｇ／ｍｌ。批内ＣＶ＜５％，批间ＣＶ＜７％。健康男、女献血员各３２例和７４例老年人，血清Ｍｂ测定结果，参考值上限分别为５５．４０、５０．６７和６５．７５ｎｇ／ｍｌ。１５例急性心肌梗塞（ＡＭＩ）患者血清Ｍｂ含量均大于１３０ｎｇ／ｍｌ．滴金免疫测定法可在５ｍｉｎ内完成检测，Ｍｂ含量＞１００ｎｇ／ｍｌ为阳性。７例ＡＭＩ患者检测结果均为阳性。两种方法结合应用对ＡＭＩ的早期诊断及疗效观察极有价值。

Level of functioning of siblings and parents of probands of varying degrees of retardation

A further analysis of already published data supports the position that retardates of low ability level less frequently have retarded siblings, retarded parents, and parents low in occupational level than do retardates higher in ability level. The analysis supports the position that there are two types of retarded individuals, persons retarded as a result of gene or chromosomal anomalies, brain injury, etc., who more frequently occur in the lower-level retardate group, and persons whose retardation represents polygenic segregation, who more frequently occur in the higher-level group.

Anatomical study of distribution of valves of the cutaneous veins of adult''s limbs

Since the cutaneous veins of the four limbs have been used as autogenous grafts in the treatment of cardiovascular disorders, knowledge of distribution of the valves is increasingly required depending upon the use. In the gross anatomical study of distribution of valves of the trunci venae, there has been argument about locational relationships between the venous roots and the valves in the vicinity of the roots and the inter-valvular distance. However, there have been only few reports discussing detailed information about valves of the cutaneous veins of the four limbs. The authors observed patterns of distribution of the cutaneous venous valves of the four limbs of cadavers prepared for practice in anatomy. The following parts were excised from each cadaver: the cephalic, basilic, and the great saphenous veins, which originate from the acral venous network and flow into the proximal deep veins, and the venous roots communicating with these veins. An incision was made on each excised vein in the direction of the long axis under observation with a stereoscopic microscope, and the inter-valvular distance and the distance between the valve and the orifice of venous root in the vicinity of the valve were measured. The inter-valvular distance varied with type of the truncus venae, and it varied according to area even in the same truncus venae.

Mechanisms of generation of slow components of bioelectric activity in diagnostics of functional state of the gastrointestinal tract

New electrophysiologic devices were used for the diagnostics of the state of excitable structures in the gastrointestinal tract and correction of their motor functions. Bioelectrical and biomechanical activities form the basis of functioning of internal organs. The mechanisms of generation of slow bioelectrical activity that are important for clinical and physiological studies are described. One of these mechanisms is a capacitance parametric transducer converting the energy of contractions into specific electric signals reflecting muscle functions. Another mechanism results from slow oscillations of resting potentials of interrelated excitable cells in large neuromuscular structures of internal organs. The elaborated procedure is efficient for preventing early postoperative paresis of the gastrointestinal tract.

Assessment of the efficacy of treatment of hemangiomas

Assessment of the aftereffects of cryoexposure and ultrahigh-frequency cryoexposure on hemangioma tissue of various types, cavernous and squamous, showed a higher cryogenic effect in hemangiomatous tissue preexposed to ultrahigh-frequency waves. A quantitative criterion is proposed for assessing the efficacy of the studied methods of exposure.
