Backprocessing paraffin wax blocks for subgross examination.
A method called "backprocessing", for subgross examination of sections, ranging between 50 microns and 1 mm in thickness using a dissecting microscope was developed. It requires either archival or current diagnostic breast tissue. In this study tissue is assumed to have been already embedded in paraffin wax for immediate diagnostic purposes. The advantages of backprocessing include the ability ...
متن کاملParaffin-wax baths in the treatment of rheumatoid arthritis.
The physical treatment most frequently used for the hands in rheumatoid arthritis is the local paraffinwax bath. It was first described by Humphris (1919) and since then has been in general use. The standard textbooks of physical medicine and rheumatology refer to wax baths as being of value, but we have been unable to find any critical attempt to assess this. It is unusual for a patient with r...
متن کاملA latchable microvalve using phase change of paraffin wax
This paper presents a novel latchable phase-change microvalve that can potentially be used for flow gating in portable lab-on-a-chip systems here minimal energy consumption is desired. The microvalve innovatively exploits paraffin wax of low melting point, whose solid–liquid phase hanges allow the closing and opening of fluid flow through deformable microchannel ceiling. The latchable phase-cha...
متن کاملHoney dressing versus paraffin tulle gras following toenail surgery.
OBJECTIVE Anecdotal reports suggest that certain honey dressings have a positive effect on wound healing. However, there is limited empirical evidence supporting its use. This double-blind randomised controlled trial investigated the effect of a honey dressing on wound healing following toenail surgery with matrix phenolisation. METHOD Participants (n=100) were randomly assigned to receive ei...
متن کاملThe mass staining of paraffin sections before the removal of wax.
The problem of producing large nwmbers of sections for teaching purposes and staining them by haematoxylin and eosin has become acute in.the post-war years, due to the shortage both of trained technicians and of reagents, especially ethyl alcohol. Methods previously used have suffered from the disadvantages of being too long, or wasteful of reagents, and it was with these factors in mind that t...
