However, nonneoplastic [CD43.sup.+] B-cell populations can be identified in paraffin sections
in some circumstances, such as in subepithelial regions of the tonsils, myo/lymphoepithelial sialoadenitis, atypical marginal zone hyperplasia, as described in children, (9) and in reactive lesions of the terminal ileum (including Peyer patches).
The paraffin sections
used in this experiment were obtained from the same tumors that were used for the apoptosis analysis.
We observed PCNA and P -ERK staining on aortic tissue paraffin sections
in four perpendicular fields of vision for each sample.
Low-power view of paraffin sections
of a cornea immunostained with AE5 antibody without any counterstaining 36 h after scraping of the peripheral epithelium plus surgical excision of the limbus (A-C).
Therefore paraffin sections
were deparaffinized with xylol and a decreasing series of ethanols.
Another case reported as benign osteoblast-rich lesion on imprint smears was later diagnosed as low-grade osteosarcoma on paraffin sections
. Two cases rendered as benign spindle cell lesion on imprint smear were subsequently diagnosed by paraffin sections
as sarcoma NOS and biphasic malignant tumor.
This kind of tumor can be distinguished more easily by paraffin sections
, but when a frozen section is the sole technique of diagnosing, the tumor may be misdiagnosed.
DNA recovered from tissue in paraffin sections
was successfully amplified and detected with this assay (data not shown), confirming the presence of C.
In this study, the structures of the seed coats of mature seeds from hulled and hull-less squash were compared using microscopic examination of paraffin sections
and scanning electron microscopy.
Sections cover histopathological diagnosis; different colon diseases with chronic constipation; a laboratory guide to histopathological diagnosis of intestinal motility disorders; preparation of cryostat sections from biopsies and colorectal specimens; and immunohistochemical techniques of paraffin sections
in the diagnosis of gut dysmotility.
In paraffin sections
, fibrin is strongly eosinophilic (Bancroft and Stevens, 1996; Bancroft and Gamble, 2005).
