颈椎单开门椎管扩大成形术临床观察及并发症的预防

随着颈椎单开门椎管扩大成形术的普及 ,其手术侵袭小、安全、相对简单的优势 [1 ] ,已被骨科医师所共识。然而许多学者已注意到术后一些并发症的危害 ,并不断总结经验 ,使这项技术渐致完善。我院自 1998- 0 8～ 2 0 0 1- 0 8开展单开门手术 5 6例 ,有 4 8例随访 6个月～ 1a,效果良好 ,无并发症出现 ,现总结如下。1　对象和方法1.1　对象　本组男 37例 ,女 11例 ,年龄 33～ 74岁 ,平均 5 6 .1岁。其中发育性颈椎椎管狭窄 (development cervical stenosis,DCS) 15例 ,颈椎后纵韧带骨化 (ossification of posterior longi-tudinal ligament,O…     

山东、河南两省3年应届高中毕业男生初检血压情况的调查分析

目的：观察山东、河南两省招飞工作初检中应届高中毕业男生血压情况。方法：采用标准汞柱式血压计测量受检者右臂肱动脉，血压计袖带下缘距肘窝2-3cm处，加压时不能过速、过快，汞柱下降速度2～3mmHg／s，测量3次，求平均值，如血压偏高，2-3h后复检，个别的次日复检。结果：两省高中毕业男生以收缩压140～148mmHg为主，其他升高和降低情况所占比例较低。结论：两省高中毕业男生血压情况构成无明显差别，血压升高主要与情绪有关。     

格林——巴利氏综合征血液流变学观察

血液流变学已用于许多疾病的研究,对某些疾病的诊断和治疗起到有益的指导作用。格林—巴利氏综合征(GBS)的血液流变学观察尚未见正式报道。今将我院1988～1990年收治的42例GBS患者血液流变学8项指标的对照观察结果报告如下。 1 临床资料与方法 1.1 临床资料 42例中男25例,女17例,

饮水有机浓集物致突变活性影响因素的研究

本文探讨饮水有机物浓集流速及加氯量对致突变活性的影响。试验表明，饮水有机物浓集流速控制在每分钟２倍树脂柱床体积时，可获得最佳致突变效果。当加氯量≥２０ｍｇ／Ｌ时，对ＴＡ９８±Ｓ９和ＴＡ１００—Ｓ９菌株有致突变活性，≤２ｍｇ／Ｌ时对ＴＡ９８±Ｓ９和ＴＡ１００±Ｓ９菌株无致突变活性。为最大限度减少致突变效应，在净水过程中保证流行病学安全前提下，减少加氯量和加氯次数是十分必要的。     

ACTIVIT OF HUMAN PLACENTAL GAMMA GLOBULININ BLOCKING IMMUNE FUNCTIONS IN VITRO AND IN ABROGATING THE XENOGENEIC, LOCAL GRAFT-VERSUS-HOST-REEACTEON

In order to understand the mechanism of immunosuppression caused by infusion of placental gamma globulin (PGG) in patients with renal allografts, rheumatoid arthritis, and graft – versus –host disease (GCHD) following bone marrow transplantation (BMT) ,we have examined the effect of PGG in vitro and in a model of the xenogeneic , local graft –ver- sus – host reaction (LGVHR) .PGG inhibited lymphocyte proliferation in mixed lymphocyte cultures (MLC) (P<0.005) and depressed interleukin -2 (IL-2) levels in such cultures at 72 hours (P<0.01) . In contrast phytohemagglutinin (PHA) –and pokeweed mitogen (PWM) –induced T and B lymphocyte blastogenesis was not affected by such PGG treatment .PGG treatment .PGG neither decreased the [3H] TdR pulse incorporation in unstimulated lymphocytes nor affected cell viability .Cell cycle analysis by flow cytometry showed that PGG reduced the percentage of cells in S and G2, M phases during the MLC, but did not alter cell cycling during PWM-stimulated proliferation . An immunosuppressive effect of PGG on the LGCHR was tested in a model of intracutaneous transplantation of PGG –treat human lymphocytes into cyclophosphamide – immunosuppressed rats. Lymphoprep – separated human tonsillar lymphocytes were incubated with RPMI-1640 buffer containing：（1）PGG,4mg/ml,(2) human plasma albumin,4mg/ml,(3)mitomycin-C,25ug/ml, or (4) no additive. Cell of each preparation (3x107cells in 0.1ml) were injected intracutaneously into cyclophosphamide-treated male rats at separate abdominal locations. A fifth site received only the buffer solution. Five days after injection of cells ,each rat received [125 I]IUdR (10uCi) intraperitoneally and was killed after 5 hours. For each site of injection, the diameters of induration were measured and 125 I was counted . There was no difference between buffer – treated and a ibumin – treated groups either in the diameter of the area of induration (t=0.66;P>0.5)or in radioactive counts(t=0.22;P>0.05).In the PGG –treated group, the induration and radioactivity measurements were significantly less than in control groups (t=3.72 and P<0.1;t=2.62 and P<0.02,respectively ) Cytophilic antibodies in PGG were thought to inhibit an early phase of T cell activation, and not to be cytotoxicity .In the LGVHR, the immune response might be abrogated either by immuno- regulatory suppression of T cell function or by toxicity to the infused lymphoid cells. For some clinical purposes, immuno- modulating, human antibodies might be preferred to murine, monoclonal antibodies.
