Paraffin Embedding Technique for Specimens Obtained by Vitrectomy

Paraffin embedding technique for specimens obtained by vitrectomy.

Histologic and immunohistochemical preparation of pathologic fluids containing cellular material is difficult, because the techniques are limited by the amount of cellular material. Similar problems limit the preparation of vitrectomized material. Cytopreparatory techniques, including millipore filter and celloidin bag cell block, have been introduced since 1980 for diagnostic vitrectomies. The...

Synovial specimens obtained by knee joint biopsy.

It has been my privilege to spend the past two months with our Swedish friends at the Karolinska Sjukhuset in the Department of Internal Medicine. This experience has been very rewarding, exceeding all my expectations. I wish to express my warm appreciation to Professor Nanna Svartz who made this possible and to thank her for the kind invitation to participate in these meetings. I am honored to...

A Rapid Method of Paraffin Embedding

Agar-gelatin for embedding tissues prior to paraffin processing.

Benchmarks Fixed tissues often need to be arranged in a particular configuration , order, or orientation prior to processing for paraffin embedding. Although it is possible to arrange tissues after infiltration (during the final stages of paraffin embedding), it can be more convenient and practical to do this at the time of dissection or tissue collection. Agar has been the classical medium use...

Application of paraffin bait technique to the isolation of Nocardia asteroides from clinical specimens.

The principal findings of a study for further evaluating paraffin baiting as a routine laboratory diagnostic procedure in the isolation of Nocardia asteroides, the etiological agent of nocardiosis, are reported.
