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.     

中南地区正常人血清α_1─抗胰蛋白酶检测结果分析

通过对中南地区１５７７例正常人的血清α_１－抗胰蛋白酶（α_１－ＡＴ）水平的测定，结果２０～４０岁组正常值为１３６．９ｍｇ％，４１～６０岁组正常值为１２９．３ｍｇ％，男女性别间的α_１－ＡＴ水平差异无显著意义。而两个年龄组间差异有显著意义。并对测定结果作了分型。     

我国司法精神病学的历史与发展

司法精神病学是一门边缘学科,既是精神病学的一个分支,又是法医学的一个分支,这种双重属性不仅决定了它在学科上的特殊地位,而且由于我国特有的司法精神病学鉴定机构设置,使得管理体制显得十分复杂,许多问题至今仍未完全解决。在全国人大《关于司法鉴定管理问题的决定》(2005)(     

α-干扰素中枢镇痛功能及其结构基础

神经系统和免疫系统之间有着广泛的联系,细胞因子在其中起着重要作用.细胞因子被证实有免疫调节和神经、内分泌等多种生物学效应,具有多个功能位点和结构域,并且可以与不同受体或受体亚型相结合,产生相应的生物效应[1～3].α-干扰素(IFNα)是研究最早的、也是研究最多的作用于神经系统的免疫细胞因子之一,其中枢镇痛功能及其结构基础是近年来研究的热点.本文就国内外对这方面的研究综述如下.     

上海市中西医康复医学研究所成立

1993年3月初,上海市卫生局批复上海医科大学,同意成立上海市中西医结合康复医学研宄所。该所设在上海医科大学附属中山医院,经费、编制由上医大和中山医院统筹安排。市卫生局指出,希望加强领导,积极扶植此项工作。     

一种胰岛素抵抗的糖尿病特殊类型报告

报告５例对胰岛素抵抗的糖尿病特殊类型病例，其均具有胰岛素应用指征，但使用胰岛素后血糖却反而上升，逐渐增加胰岛素用量，则血糖值亦呈上升趋势。对该类病人的治疗，首先停用胰岛素，改用自制中药制剂及优降糖、降糖灵治疗，取得了良好效果。
