龈沟液ALP活性与牙周病的关系

对牙周健康者和龈炎、牙周炎患者２５人共１３０个牙位的龈沟液（ＧＣＦ）中硷性磷酸酶（ＡＬＰ）活性进行了检测。ＧＣＰ－ＡＬＰ活性（ｕ／ｕＬ或ｕ／牙）在炎症牙位和健康牙位间有显著差别，与牙龈指数（ＧＩ）和附着丧失（ＡＬ）呈正相关性。炎症牙位经牙周综合治疗６周后，其ＧＣＦ－ＡＬＰ活性显著降低。说明ＧＣＰ－ＡＬＰ水平能反映出牙周组织炎症的进展情况。     

口服法小肠气钡双对比造影对小肠疾病的影像诊断

目的:探讨口服法小肠双对比造影检查及病变表现特点。方法:辅以高、低张药物,口服80%(w/v)硫酸钡200ml加经肛门逆行注入空气2000ml进行小肠双对比造影检查,显示双对比小肠影像。结果:147次小肠造影检查中118例成功地用该方法进行小肠双对比造影检查,成功率80.27%,年龄14岁至69岁,平均34.3岁。118例中阳性32例,阳性显现率27.12%,病理证实的25例,占阳性病例的78.13%。不能应用高、低张药物和逆行注气失败的共29例,占19.73%。小肠肿瘤、Crohn's病、Meckel's憩室和回肠末段淋巴滤泡增生症小肠疾病的双对比影像具有特征性表现。结论:(1)此法小肠双对比造影检查简便易行,适合各类有电视X线机的放射科开展。(2)小肠病变在双对比影像上表现特征明显,易于诊断。(3)不能应用高、低张药物和肛门括约肌松弛的患者用此法检查将受到限制。     

Detection of linkage under heterogeneity: comparison of the two-locus vs. admixture models.

Linkage analysis under the two-locus model and the admixture model was compared on pedigree data for a common disease stimulated under a model of genetic heterogeneity. The ascertainment of families was designed so that the samples had a large proportion of families segregating for both disease loci. The two-locus linkage analysis model did not demonstrate increased power of detecting linkage or more accurate estimates of the recombination fraction, theta than did the admixture model linkage analysis. When a sample was purposely chosen so that all of the families were segregating for both loci, then the two-locus lod score analysis was better. However, the increased power depended on assuming the correct gene frequency for the linked locus. It can be concluded that under the conditions of genetic heterogeneity examined here, testing for linkage under the admixture model is the preferred method of analysis. However, this is not a general conclusion that can apply to all two-locus disease models.     

传染病研究40年（1955～1995年）

本文综述本校传染病学教研室１９５５～１９９５年间所取得的科研成果。内容包括１０余种传染病与寄生虫病的临床和基础研究，其中以华支睾吸虫病、恙虫病等有广东特色的传染病以及伤寒、痢疾、病毒性肝炎等影响人民健康最普遍的传染病为重点。反映了建国以来各个时期本教研室对防治这些传染病所作的贡献。所取得的成果，相当一部分通过多年来的验证，已获得广大传染病工作者所认同或列为常规，部分已获得部委级奖励。现在重温这些成果，可能起承前启后的意义。     

沈阳口岸入出境人员传染病监测工作报告

本文阐述了1990年-1993年间沈阳口岸入境人员传染病监测工作的基本情况，在对6503名归国人员和2146名外籍人员进行传染病监测体检中，发现HIV感染者41人、隐性梅毒患者1人、开放性肺结核患者1人。     

血清唾液酸对血液病临床价值的初步报告

报道64例各类血液病患血清唾液酸（SA）值的测定，并与84例健康对照组进行比较。结果经统计学分析：病例组（631．5±130．3μg/ml），病例组中的ANLL（672．6±98．38μg/ml），ALL（630．8±29．3μg/ml），CML－A（617．5±122．7μg/ml），MM（606．0±138．7μg/ml四组与对照组比较，差异有极显意义（P＜0．01）；各病型组SA阳性率明显高于健康对照组，表明SA值的测定对恶性血液病的诊断有一定的临床意义。     

纤维结合素角膜上皮愈合作用的研究

人血浆纤维结合素对家兔刮除和板层切除后的角膜上皮愈合均有一定促进作用，角膜上皮裸区明显缩小，优于对照眼。临床治疗５类角膜上皮障碍５９例６１眼，均获得显著疗效。     

膀胱前间隙炎性假瘤临床病理观察及文献复习

目的 探讨膀胱前间隙炎性假瘤的临床病理特征及发病因素，以提高对本病的认识。方法 复习3例膀胱前间隙炎性假瘤的临床特征、组织病理学、免疫表型及相关文献。结果 3例患者均为女性，均为输卵管结扎术后1～2年发现膀胱前间隙炎性假瘤，CT及B超提示膀胱前壁肿块，但膀胱黏膜光滑。术中发现肿块位于膀胱前间隙并累及膀胱前壁。病理检查：眼观为灰白色质韧的结节状肿块，镜下见炎性假瘤的病理特征及不同程度炎症背景，有组织疏松区、黏液样区、部分区域梭形细胞和纤维母细胞排列杂乱，细胞较大，光镜检查时易误诊为肉瘤，但缺乏核异型。3例均成功行肿块连同部分膀胱壁切除术，随访3～5年无复发。结论 膀胱前间隙炎性假瘤形态上需与软组织肉瘤、结节性筋膜炎、术后梭形细胞结节、间质性膀胱炎等疾病相鉴别，既往输卵管结扎术和感染可能是其重要的致病因素。     

Transfer of occupational health problems from a developed to a developing country: Lessons from the Japan–South Korea experience

Many corporations move their manufacturing facilities or technologies from developed to developing countries. Stringent regulations have made it costly for industries to operate in developed, industrialized countries. In addition, labor costs are high in these countries, and there is increasing awareness among the general public of the health risks associated with industry. The relocation of hazardous industries to developing countries is driven by economic considerations: high unemployment, a cheaper labor force, lack of regulation, and poor enforcement of any existing regulations make certain countries attractive to business. The transfer of certain industries from Japan to Korea has also brought both documented occupational diseases and a new occupational disease caused by chemicals without established toxicities. Typical examples of documented occupational diseases are carbon disulfide poisoning in the rayon manufacturing industry, bladder cancer in the benzidine industry, and mesothelioma in the asbestos industry. A new occupational disease due to a chemical without established toxicities is 2‐bromopropane poisoning. These examples suggest that counter‐measures are needed to prevent the transfer of occupational health problems from a developed to a developing country. Corporate social responsibility should be emphasized, close inter‐governmental collaboration is necessary and cooperation among non‐governmental organizations is helpful. Am. J. Ind.
