Equine herpesvirus type 1 infected cell polypeptides: evidence for immediate early/early/late regulation of viral gene expression

EHV-1 polypeptide synthesis was examined in productively infected rabbit kidney and hamster embryo cells. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analyses of extracts from [35S]methionine- and 3H-amino acid-labeled-infected and mock-infected cultures revealed the presence of 30 infected cell-specific polypeptides (ICPs) which ranged in apparent molecular weights from 16.5K to 213K. Twenty-two of these ICPs comigrated with virion structural proteins. Four ICPs (203K, 176K, 151K, 129K) were detected in extracts of infected cultures labeled in the presence or absence of actinomycin D (Act D) immediately after release from a 4-hr treatment with cycloheximide (CH). These polypeptides, which were designated as EHV-1 immediate early (alpha) ICPs, were not detected in unblocked (non-CH-treated) infected cells. The most abundant ICP was a 31.5K nonstructural protein which, in addition to a 74K protein, was detected in unblocked infected cells at 2-3 hr postinfection. These proteins appeared to be regulated as early (beta) ICPs, since neither protein was observed in Act D-treated cultures released from CH block. Twelve ICPs were classified as late (gamma) polypeptides on the basis of their reduced synthesis in cultures in which viral DNA replication was inhibited by phosphonoacetic acid. All but one (40K) of these late ICPs corresponded to virion structural proteins.     

大学生的焦虑心理分析

为了解当前大学生的心理健康状况，本研究通过一项对河北某高校2071名在校大学生的SCL-90调查，结果表明。该校的大学生中，心理问题的发生率由高到低依次为焦虑、强迫、人际敏感等。针对焦虑现象比较突出这一特点，运用自编的半开放式量表进行访谈，对焦虑情绪进行分类和产生原因分析，并且希望以此为参考，去探讨对大学生焦虑问题的一些对策。

A histopathologic study of gastric and small intestinal graft-versus-host disease following allogeneic bone marrow transplantation

Twenty-two stomach and 14 small intestinal biopsy specimens from 24 allogeneic bone marrow transplant recipients were reviewed to evaluate the histopathologic changes of graft-versus-host disease (GVHD) in these organs. Associations between these results and clinical symptoms and other biopsy results were sought. In both organs, single epithelial cell necrosis was found to correlate with GVHD. Gastric GVHD was diagnosed in eight patients and small intestinal GVHD in four. Gastric GVHD was characterized by nausea, vomiting, and upper abdominal pain without diarrhea (the latter being present in only two patients), while all four of the patients with small intestinal GVHD had upper gastrointestinal symptoms and diarrhea. These symptoms correlated with concurrent rectal biopsy findings; pathologic alterations were seen in only one of six specimens from patients with gastric GVHD but in three of four with small intestinal GVHD. These findings suggest that stomach biopsy may be necessary to diagnose GVHD in patients with upper gastrointestinal symptoms but no diarrhea and normal rectal biopsy specimens. Diagnostic problems may arise in the early posttransplantation period, when the effects of cytoreductive therapy may simulate GVHD, and in patients with gastrointestinal cytomegalovirus infection, which may also produce changes identical to those of GVHD.
