Cell implants reconstruct myelin sheaths

BMJ, 1999
Scientists have succeeded in remyelinating damaged areas of the central nervous system and restoring lost function by transplanting glial cells directly into the spinal cord of animals. This reconstruction feat, until recently thought impossible, raises hopes of finding treatments for diseases with persistent myelin loss, such as multiple sclerosis ...

Concepts in Myelin Sheath Evolution

2001
Abstract What were the evolutionary pressures that led to the recent (in evolutionary terms) invention of the morphologically complex, biochemically unique and functionally essential vertebrate myelin sheath? It is frustrating that a definitive answer to this question may remain elusive.

Renewal of Phospholipids in the Myelin Sheath

1976
It is apparent from previous work that the major brain phospholipids are synthesized in the endoplasmic reticulum and in vivo are transferred to ‘myelin’ in both developing and mature animals (l). Nevertheless, no transfer of phospholipids from ‘microsomes’ to ‘myelin’ has been demonstrated in vitro (2), after subcellular fractionation, as it has been ...

Spermidine: A constituent of the myelin sheath?

Neuroscience Letters, 1978
Abstract Spermidine, an aliphatic polyamine present in high concentrations in the white matter, could act as a bivalent ligand stabilizing myelin lamellae. To seek an answer to the title's question, polyamines were extracted from the subcellular fractions of rat brain after intracerebral injection of [14C]putrescine, a precursor of spermidine ...

Multiple Myelin Sheaths in Single Schwann Cells

Nature, 1962
DURING an electron microscopic investigation of the normal structure of the trigeminal ganglion in the rat, particular attention was given to various stages of myelin sheath formation1. Frequently it was observed that two or more myelinated axons were enclosed within the cytoplasm of a single Schwann cell. Such a finding was difficult to correlate with

Pathology of the myelin sheath

1995
Abstract Diseases affecting the myelin sheath encompass a wide variety of clinical and experimental conditions. This chapter discusses the essentials of the processes of demyelination and remyelination, and relates these to multiple sclerosis (MS).

[Myelin sheath staining (author's transl)].

Zentralblatt fur allgemeine Pathologie u. pathologische Anatomie, 1975
In Loyez-Woelcke's myelin sheath staining the author studied the effect of the tanning time, that of the ripening grade of hematoxylin as well as the effect of the staining time. In case of a determined staining time a certain proportion must be present between the ripening grade (or the quantity of the oxidizing agent added to the solution to enhance

[Silver impregnation of myelin sheaths].

Zentralblatt fur allgemeine Pathologie u. pathologische Anatomie, 1986
A method is described, based on mordantiation with phosphotungstic acid and tannic acid plus impregnation with silver nitrate solution (pH 10.4) and a physical developing technique. Water glass is used as a protective colloid in the developer.
