Electro-oculogram of Retinal Vein Occlusion

Twenty five cases, including 26 eyes with retinal vein occlusion (RVO) were examined by means of the electro-oculogram. The results showed that 23 of the 26 eyes suffering from RVO exhibited abnormalities of the electro-oculogram (EOG). The potential difference and Arden ratio in the RVO eyes were lower than those in the normal eyes (P<0.01). The more the visual acuity of ill eyes was decreased, the higher the abnormal rate of EOG in ill eyes was. 14 eyes had the visual acuity less than 0.1, whose EOGs were abnortmal. Six eyes had the visual acuity from 0. 2 to 0. 4, in which the EOGs of 5 eyes were abnormal. Six eyes had the visual acuity more than 0. 5, a-mong which the EOGs of 4 eyes were abnormal. Based on the above observations, it may be considered that the circulatory disturbance resulting from RVO damages not only the internal layer but also the external layer of the retina. We suggest that EOG is a useful method for distingquishing lesions caused by RVO and may reflect the functional condition     

Observation on 108 Normal Ophthalmic Arteries in 80 Patients by Digital Subtraction Angiography

By digital subtraction angiography(DSA), the authors made observations on 108 normal ophthalmic arteries in 80 patients with regard to the origins, courses, branching, morphology and anastomoses of the vessels. The merits and demerits of DSA in observing the ophthalmic artery were discussed. Eye Science 1994; 10: 157- 162.

职业接触氯乙烯对生殖功能影响的调查

对全国１２个城市中１３个聚氯乙烯制造工厂中２７３６名接触氯乙烯的工人及３４４２名对照厂工人，进行了生殖功能的流行病学调查研究，结果表明，接触氯乙烯男、女工人的各项生殖结局指标与对照组比较无显著性差异，但女工氯乙烯接触组妊娠合并症的发生率明显高于对照组，表明氯乙烯对女工的妊娠过程有一定影响，因此积极改善劳动条件，不仅对保护工人健康，而且对保护其子代的正常发育成长也有重要意义。     

肝动脉化疗栓塞对胃肠影响及处理

大量文献表明，肝动脉插管化疗栓塞是治疗肝癌有效方法之一，随着技术进步，超选择插管、综合治疗及二期手术切除能明显提高疗效。但严重并发症的发生影响病人术后的灰复，延误及时进行二期手术，甚至直接引起死亡。呼动脉插管化疗栓塞的主要并发症有胃肠反应、肝功能损害、肾功能损害、误诠靶器官、发热等，其中胃肠并发症是最常见的共发症（1、2）。木文结合文献报导的动物实验结果，分析本院138人次脉动脉插管化疗栓塞治疗原发性肝癌所出现的胃肠道并发症的临床表现，试探讨较有效、较妥当的治疗方法。1．材料：1．1本组68例，男63例，女…     

碘盐防治对改善缺碘地区儿童智力的调查分析

众多资料研究证实缺碘地区儿童智力明显低于非缺碘地区。为了解碘盐防治后缺碘地区儿童智力水平,验证防治效果,对我县实施碘盐防治措施20余年的缺碘地区什字乡(下称防治区)学龄儿童进行了智力调查,并以未经防治的缺碘地区石岔乡(下称未防治区)和非缺碘地区黄锋堡乡作对照。对象和方法一、一般情况:什字乡位于六盘山东侧腹地(?)区。是原地甲病重病区。水碘范围0.1～     

美国儿科临床药学服务介绍

早在一个多世纪以前，儿科用药就显示出了它白与特殊性．然而药学界对此却迟迟不能认同，直至本世纪70年代．药学文献中才明确提出了要为儿科患看提供特殊的药学服务以避免各种可能的药物治疗中的差错的观点。

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.
