    Notes: [Auszug] In discussion at a symposium at Liblice2, Professor E. Gutmann and Dr H. Koenig suggested that we should try to prepare a residue of myelin from dorsal spinal roots by plucking out their axons with forceps after treating these peripheral nerves with a glycine-diethylamine buffer3. This suggestion ...

    HISTOCHEMISTRY OF MYELIN–XV. CHANGES IN THE MYELIN PROTEINS OF THE PERIPHERAL NERVE UNDERGOING WALLERIAN DEGENERATION–ELECTROPHORETIC AND MICRODENSITOMETRIC OBSERVATIONS (1972)

    Notes: The chronological order of changes in rat peripheral nerve proteins during Wallerian degeneration has been investigated by microdensitometric and electrophoretic techniques. Both methods revealed an early loss of myelin proteins. The histochemical microdensitometric study showed a very substantial early loss of stainable protein basic groups and a somewhat slower progressive loss of the major protein component of peripheral nerve myelin (the J band). The electrophoretic study showed an early loss of both the J band protein and the slower-moving basic protein band. The histochemical study also suggested that some cerebroside may be lost in the early stage of Wallerian degeneration. It is concluded that degradation of myelin proteins is an initial event in the process of myelin breakdown.

    HISTOCHEMISTRY OF MYELIN XIV PERIPHERAL NERVE MYELIN PROTEINS: ELECTROPHORETIC AND HISTOCHEMICAL CORRELATIONS (1972)

    Notes: Abstract— Myelin from the peripheral nervous system has been shown to contain two basic protein components and an electrophoretically slower-moving major protein, the ‘J’ band. The ‘J’ band protein cannot be selectively removed by aqueous or organic solvents and does not correspond to proteolipid or acidic protein. Histochemical stains applied to peripheral nervous systems myelin proteins separated by polyacrylamide electrophoresis indicate that ‘J’ band protein is analogous with the neurokeratin of the nerve sheath. Trypanophilia observed histochemically in unfixed myelin is principally due to basic proteins. With prolonged tryptic digestion ‘J’ band protein is degraded. Thus, previous classifications of myelin proteins based on trypsin sensitivity have been modified. All peripheral nervous system myelin proteins should be regarded as trypsin-sensitive, the basic protein being relatively more and the ‘J’ band protein relatively less susceptible.

    PROTEOLYTIC ACTIVITY AND BASIC PROTEIN LOSS IN AND AROUND MULTIPLE SCLEROSIS PLAQUES: COMBINED BIOCHEMICAL AND EIISTOCHEMICAL OBSERVATIONS (1972)

    Notes: Abstract— This combined histochemical and biochemical study has shown that acid proteinase activity (PH 3.5) is increased around histologically-defined active plaques of multiple sclerosis (MS). Biochemical estimation showed that the enzyme is more active in most samples of ‘normal’ white matter in MS than in controls. A gradient of enzyme activity was observed: control white matter-white matter distant from plaqueclose white matter-edgsplaque. Both electrophoretic and histochemical techniques revealed a reduction or absence of basic (encephalitogenic) protein in the plaques. Electrophoresis showed a diminution of encephalitogenic protein outside some plaques. Phospholipids that remain on the base-line of thin-layer chromatoplates were shown to be predominantly phosphoinositides combined with encephalitogenic protein

    HISTOCHEMISTRY OF MYELIN. XIII DIGESTION OF BASIC PROTEIN OUTSIDE ACUTE PLAQUES OF MULTIPLE SCLEROSIS (1971)

    Notes: Abstract— Plaques of multiple sclerosis from a patient with a short clinical history were investigated by qualitative and quantitative histochemical methods. One of three plaques examined showed perivenous lymphocytic infiltration; this plaque was regarded as a particularly early acute lesion. In this plaque a relatively wide zone of diminished staining for basic protein extended outwards around the edge of the lesion. A narrower and irregular zone of diminished cerebroside staining was also seen around the plaque. Staining for phosphoglycerides and cholesterol was relatively normal up to the edge of the lesion; no zone of reduced staining for these lipids was seen outside the plaque. Proteolytic activity was increased throughout the lesion (pH 3.5 〉 7.4). The two less acute plaques showed no obvious loss of basic protein and cerebroside outside the plaque. Addendum: Two further acute plaques of multiple sclerosis obtained recently, showed a similar loss of basic protein outside of lesion.

    Notes: Abstract— Phosphotungstic acid haematoxylin, trypan blue and amidoblack techniques have been developed as anionic dye methods for staining myelin basic proteins. All methods displayed central and peripheral nervous system myelin in histochemical prepa rations and stained brain basic proteins in electrophoretic polyacrylamide gels: phosphotungstic acid haematoxylin appeared to be the most selective of these techniques. Electron photomicrographs of peripheral nerve stained by phosphotungstic acid haematoxylin showed that the major part of myelin basic protein is located in the period dense line. The basic proteins stained by phosphotungstic acid haematoxylin showed an early loss in rat sciatic nerve undergoing Wallerian degeneration and had completely disappeared from the centre of 20 plaques of multiple sclerosis.

    Osmium tetroxide as a histochemical and histological reagent (1967)

    Notes: Summary From the evidence discussed it can be concluded that osmium tetroxide (OsO4) would be reduced to black OsO2 (or an equivalent compound) by the ethylene bonds of liquid or solid cis-unsaturated lipids or by the Δ 5-double bond in cholesterol in solid state in tissues. No evidence has been obtained to suggest that OsO4 is either reduced or bound by proteins and polysaccharides in tissue-sections.

    Reappraisal of osmium tetroxide and OTAN histochemical reactions (1968)

    Notes: Summary Osmium tetroxide and OTAN histochemical reactions have been reappraised following recent publications in this journal by Ellbder and Lojda. Provided that the standard OTAN reaction is used on frozen sections of conventional thickness, unsaturated hydrophilic polar lipids are stained in an orange or red shade while unsaturated hydrophobic non-polar lipids are stained brown-black or black. We have confirmed the anomaly — pointed out by Elleder and Lojda — that the “polar lipid” reaction of the atherosclerotic plaque is essentially extinguised by acetone. Solubility and blockading methods provide circumstantial evidence that Elleder and Lojda's assumed OsO4-protein reactions are due to the lipid moiety of a lipoprotein complex.
