We examined 28 paraffin-embedded tissue specimens with histologic evidence of herpes virus infection by in situ hybridization (ISH) utilizing manual capillary action technology (Micro Probe Staining System) and a 21 base synthetic multibiotinylated oligonucleotide probe from the HSV glycoprotein C region. The results were compared to a rapid simple immunohistochemical (IHC) protocol for detection of HSV proteins. HSV was detected by ISH and IHC in all but one specimen which was shown to be positive for varicella zoster virus by direct fluorescent antibody studies. Hybridization signal was confined to the nucleus in all cases. Staining was identified in cells with early as well as late cytopathic effect. IHC produced intense nuclear and/or cytoplasmic signal in infected cells and stained in areas of necrosis which were otherwise spared by ISH. HSV was detected by IHC and/or ISH in 3/5 specimens with histology suggestive of, but not diagnostic for, HSV infection. Both techniques were sensitive and specific for HSV, resulted in rapid detection of the pathogen in routinely processed tissues, and may be useful in cases where the histologic impression is equivocal for HSV infection. ISH for HSV may be preferred because it can identify early HSV infection, which in turn can be treated with antiviral agents. © 1994 Wiley-Liss, Inc. 相似文献

Background: Cytomegalovirus (CMV) infection has been shown to be associated with p53 overexpression in coronary artery restenosis. We investigated the occurance of this association in other forms of CMV infection using an automated in situ hybridization (ISH) technique.Methods and Results: We performed ISH for CMV using digoxigenin-labeled or biotinylated probes followed by avidin-alkaline phosphatase and nitroblue tetrazolium color substrate. Immunohistochemistry (IHC) was then performed using an anti-p53 antibody utilizing streptavidin-immunoperoxidase and 3,3-diaminobenzidine tetrahydrochloride as a chromogen. Sixteen cases with characteristic cytomegalic inclusions from a variety of body sites were examined. All 16 cases were positive for CMV by ISH. Nine of sixteen expressed nuclear p53. Six of these nine cases showed viral cytopathic effect in the cells with p53 expression. In an illustrative case, double colocalized staining for CMV and p53 protein was demonstrated in individual cytopathic cells. When microwave antigen retrieval was necessary, ISH was performed before IHC, and our standard microwaving time was reduced by two-thirds.Conclusions: The colocalization of p53 protein overexpression with CMV within single cells adds further evidence that this overexpression is a viral-induced phenomenon. The combined ISH and IHC assay can be carried out in a rapid automated mode, increasing the ease of investigating relationships between message and protein expression within single cells in a wide variety of settings.

A case of interhemispheric subdural hematoma (ISH) following closed head injury is reported. Our patient had seizures and mental status changes. Cranial computed tomography (CT) demonstrated areas of increased density along the right side of the falx cerebri and over the right leaf of the tentorium cerebelli. Conservative treatment was chosen and the patient recovered. Ten other patients with ISH were compared with ours. Head injury is the leading cause of ISH. Most patients display confusion, lethargy, or a "falx syndrome," with a delayed interval of prominent neurological deficits from the time of injury until presentation. Although patients with ISH can be successfully treated by medical management, surgical intervention may be required. 相似文献

Due to their localisations
and symptoms, interhemispheric
subdural haematomas (ISH) compose
a distinct category. Altered
level of consciousness and hemiparesis
are the most frequent symptoms.
We report a case of ISH who
presented with headache as the sole
complaint. Left cerebellar
haematoma and ISH were found in
cranial MRI and cranial computed
tomography Cranial MR angiogram
was normal. Haemogram and coagulation
parameters were within normal
limits. ISH should be considered
among the diagnostic possibilities
in elderly patients who present
with headache as the sole symptom
without other clinical features such
as meningeal irritation signs, focal
neurological symptoms and alteration
of consciousness. Cranial
imaging studies should be done in
such cases. 相似文献
