Erythema multiforme during cytomegalovirus infection and oral therapy with terbinafine: a virus–drug interaction

The authors report a case of erythema multiforme in a 32-year-old woman who was also taking oral terbinafine for an onychomycosis. The patient data analysis showed serological positivity for cytomegalovirus (IgM and IgG) and hepatitis C virus and serological titre of antinuclear antibody was elevated. After a brief review of the literature the authors propose the possibility of virus-drug interaction as a model of adverse drug reactions.     

阿昔洛韦对单纯疱疹病毒脑炎小鼠脑细胞的保护作用

目的 了解单纯疱疹病毒脑炎(HSE)脑细胞结构的改变及药物的影响。方法 采用光学显微镜及透射电子显微镜观察HSE小鼠脑细胞结构的变化，并给予阿昔洛韦(ACV)及地塞米松(DEX)治疗，观察治疗后脑细胞结构的变化。结果 HSE小鼠脑神经细胞明显肿胀，核仁固缩，核内结构破坏，线粒体及高尔基体可见空泡样变性，核仁内可见病毒颗粒。用药物干预的小鼠脑神经细胞改变较轻微，未找到病毒颗粒；与单用ACV干预的小鼠相比，用ACV DEX干预的小鼠脑神经细胞及毛细血管周围水肿明显减轻。结论 HSE早期给予ACV DEX治疗，对HSE脑细胞结构有明显保护作用。     

Neuro-ophthalmic manifestations of the syndrome of ophthalmoplegia, ataxia and areflexia Observations on 20 patients

The neuro-ophthalmological manifestations of 20 patients with the syndrome of ophthalmoplegia, ataxia and areflexia are described. The symmetrical nature of the ophthalmoplegia and the associated cerebellar ataxia point to centrally placed lesions. Several supranuclear, nuclear and internuclear ophthalmological signs are identified. Some of these, like partial sparing of the levator palpebrae and normal downgaze in the presence of severe ophthalmoplegia are noted too frequently to be just unusual signs of peripheral oculomotor dysfunction. Other identified features included upper lid retraction on attempted upgaze and preserved Bell's phenomenon in the presence of paralysis of the latter, as well as several other central ophthalmological signs. These findings contrast with those seen in the Guillain-Barré syndrome and, thus, the syndrome of ophthalmoplegia, ataxia and areflexia is not a mere variant of it.     

Autopsy findings in two cases of neonatal herpes simplex virus infection: detection of virus by immunohistochemistry, in situ hybridization and the polymerase chain reaction

We describe the pathological findings in two fatal cases of neonatal infection with herpes simplex virus. One had an encephalitis caused by herpes simplex virus type 2 (HSV-2); the other had a disseminated infection with herpes simplex virus type 1 (HSV-1). Confirmation of the diagnosis was obtained by use of the polymerase chain reaction to amplify viral DNA from paraffin sections of autopsy tissues. By using primers which amplify fragments of the HSV-1 thymidine kinase gene and HSV-2 glycoprotein gene respectively it was possible to discriminate between infection with HSV-1 and HSV-2. In contrast, immunohistochemistry and in situ hybridization using commercially available reagents did not distinguish between HSV-1 and HSV-2 infection. However, immunohistochemistry and in situ hybridization are probably more reliable than the polymerase chain reaction for assessment of the distribution of virus in different tissues.     

病毒性肝炎病人血浆VitE水平及其临床意义

观测了急性肝炎和重症肝炎病人血浆ＶｉｔＥ及Ｌｐｏ水平及其动态变化。急性肝炎和重症肝炎病人血浆ＶｉｔＥ低于对照组，Ｌｐｏ高于对照组，均以重症肝炎更明显，且死亡病例血浆ＶｉｔＥ低于存活者。部份病人口服ＶｉｔＥ不能提高其血浆水平，并随病情加重而逐渐降低。讨论了病毒性肝炎病人血浆ＶｉｔＥ降低与Ｌｐｏ升高的关系及其临床意义，认为动态观测血浆ＶｉｔＥ可作为判断重症肝炎病情进展及预后的参考。     

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。     

肝炎肝硬化患者血清IL-10、IL-18水平的变化及意义

目的探讨血清IL10、IL18在肝炎肝硬化的发病机制中的作用。方法62例肝炎肝硬化患者根据childpugh分级法分为3组:childpughA级组19例、childpughB级组23例和childpughC级组20例。采用ELISA法检测3组患者和20例健康献血员血清IL10、IL18的水平。结果childpughA、B、C级组血清IL18水平均明显高于对照组(P均<0.01),childpughA级组血清IL10水平略高于对照组,但无显著性差异(P>0.05);childpughB、C级组明显低于对照组(P<0.05);有腹水组、无腹水组血清IL18水平均明显高于对照组(P均<0.01),有腹水组血清IL10水平明显低于无腹水组、对照组(P<0.05,P<0.01);血清IL10水平与血清IL8水平呈负相关(r=-0.51,P<0.01);血清白蛋白水平与血清IL10水平呈正相关(r=0.566,P<0.01),与血清IL8水平呈负相关(r=-0.315,P<0.01);血清凝血酶原活动度与血清IL10水平呈正相关(r=0.506,P<0.01),与血清IL18水平呈负相关(r=-0.463,P<0.01);血清总胆红素水平与血清IL8水平呈正相关(r=0.677,P<0.01),与血清IL10水平呈负相关(r=-0.339,P<0.01)。结论IL10、IL18在肝炎肝硬化的发病机制中起一定的作用,其水平与肝损害程度密切相关。
