Epoxy resin as fixative during freeze-substitution.
An alternative protocol for freeze-substitution is described. Araldite/Epon embedding medium (20% in acetone) is first used as a stabilizer (as e.g., OsO(4)) and then as embedding medium. The major components of the Araldite/Epon resin formulation react with proteins and lipids and provide for an excellent preservation and reasonable visualisation of the ultrastructure. The ultrastructural appe...
متن کاملUse of saturated sodium chloride solution as a tissue fixative
The present study was carried out to examine the capability of saturated sodium chloride solution as a fixative agent instead of formalin which is regarded as a carcinogenic material. For this purpose 3 rabbits were used and their livers, kidneys and spleens were exposed and removed. Neutral buffered formalin solution, saturated sodium chloride solution and distilled water were used as fixative...
متن کاملMethanol as an alternative fixative for cytological smears.
Ninety-five percent (95%) ethanol is the standard cytological fixative used in many laboratories. Commercially available ethanol is expensive and not freely available in some institutions. Methanol, a tissue dehydrant, is also known to be a cytological fixative. However its efficacy has not been assessed or documented in the literature. One hundred and eight consecutive fine needle aspiration b...
متن کاملPermanganate—A New Fixative for Electron Microscopy
During the early phases of tissue sectioning for electron microscopy, virtually all of the standard cytological fixatives were tried. Of these, osmium tetroxide appeared to give the best preservation, and this was further improved by buffering the fixative solution at a slightly alkaline pH (Palade (1)). A variant developed by Dalton (2) contains Os04 in a chromate-dichromate system. Formalin h...

of paralysis about fourteen days after childbirth, in all probability of embolic or thrombotic origin. The paralysis involved the whole of the right side, leg, arm, and face, along with aphasia, but passed off very soon. In a few weeks it had almost disappeared, and in seven or eight months there was nothing left but aphasic symptoms. Nine months afterwards, however, mental symptoms showed them...
