    Notes: [Auszug] We have recently examined the brains of ten hedgehogs (Erinaceus europaeus) in coronal, horizontal and sagittal sections, and found cells apparently identical with mast cells which are localized to the diencephalon. These cells were observed only in the thalamus, epithalamus and metathalamus, and ...

    Notes: Résumé Des suspensions de mastocytes péritoneaux isolées de rat furent incubées avec 10 substances différentes, connues ou presumées être des neurotransmitteurs. Seulement l'adenos ine triphosphate (ATP) aux concentrations supérieures à 2.64×10−6 M causèrent la dégranulation des mastocytes. L'ATP cause également la dégranulation des mastocytes dans le mésentère. L'action de l'ATP peut être responsible de la dégranulation des mastocytes cutanées observée après la stimulation antidromique des nerfs sensorieux, alors que de l'ATP est libéré dans la peau.

    Effect of interrupting retino-hypothalamic connections on the melanophore response inXenopus laevis (1968)

    Notes: Résumé On a estimé possible que les axones rétinohypothalamiques décrits chez certains amphibiens jouent un rôle dans le contrôle neuro-endocrinien de la pars intermedia de l'hypophyse. Mais si on sectionne chez desXenopus cette voie supposée, ces animaux peuvent néanmoins modifier la couleur de leur peau lorsqu'on les place sur les terrains différents. Il n'est donc pas vraisemblable que ces connections fassent partie d'un arc réflexe contrôlant la sécrétion de l'hormone mélanotrophique.

    Effects of triiodothyronine on the cerebellar cortex of the new-born rat in tissue culture (1971)

    Notes: Résumé La triiodothyronine produit in vitro des changements régressifs dans les cellules et dans les axones du cervelet du rat nouveau-né. Il est suggéré que les hormones thyroïdes provoquent une dégénérescence accélérée des neurones dont les connexions afférentes et efférentes ont été coupées, tandis qu'elles stimulent la croissance et la différenciation des neurones aux connexions périphériques intactes

    Notes: Résumé L'argyrophilie est la propriété d'une partie constituante protéique de l'axoplasme qui peut être dissoute et reprécipitée. Il est donc probable que c'est une substance, ou un groupe de substances, plutôt qu'une organelle formée, qui est responsable de la coloration de l'axone au contact de l'argent. Les qualités de cette protéine diffèrent d'une façon marquée de celles déjà connues des protéines intracellulaires membraneuses et fibreuses.

    Notes: [Auszug] SIR-Anne McLaren (Nature 320, 570; 1986) states that the human product of conception before the 14th day of intrauterine life should not be called an "embryo" because the cells are destined to develop into both the fetus and the placenta. By implication, experimenting with or throwing away a ...

    Localization of α-d-glucosyl and α-d-mannosyl groups of mucosubstances with concanavalin A and horseradish peroxidase (1975)
    Springer
    Histochemistry and cell biology 44 (1975), S. 39-45 
    Details
    ISSN: 1432-119X
    Source: Springer Online Journal Archives 1860-2000

    Notes: Summary Concanavalin A is a lectin which is known to bind specifically to α-d-glucosyl and α-d-mannosyl groups in the mucosubstances of mammalian tissues. The lectin molecule is bivalent; after its attachment to mucosubstances present in a histological specimen it can also bind horseradish peroxidase, a mannose-containing glycoprotein. The attached peroxidase may then be visualized by virtue of its histochemically demonstrable enzymatic activity. Other investigators have utilized this principle in the electron microscopic localization of cell-surface carbohydrates. A histochemical technique for light microscopy is described here, along with three control procedures which establish the specificity of the method. The technique is somewhat more fensitive than earlier ones in which fluorescent-labelled concanavalin A was used, and has the additional advantages that all the required reagents are commercially available and that sacilities for fluorescence microscopy are not needed.

    Aprotinin, a carbohydrate-binding protein (1973)
    Springer
    Histochemistry and cell biology 34 (1973), S. 275-280 
    Details
    ISSN: 1432-119X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary Evidence is presented for a carbohydrate-binding property of aprotinin, which is preserved both in a fluorescein isothiocyanate (FITC) conjugate and a cyanogen bromidelinked Sepharose conjugate of the protein. Both conjugates similarly retain their tryptic and chymotryptic inhibitory properties. The FITC conjugate is shown to be a single species with respect to charge and to molecular weight and shows a specific binding of normal materials containing sialosyl or uronosyl groups, which accords with its histochemical behaviour. The Sepharose-conjugate showed a similar specificity.

    Histochemical detection of the α-D-arabinopyranoside configuration using fluorescent-labelled concanavalin A (1972)

    Notes: Summary A technique is described in which carbohydrates present in sections of animal tissues are stained with fluorescein-labelled concanavalin A. Evidence is presented which suggests that the fluorescent staining is due to the presence of hexose residues containing the α-D-arabinopyranoside configuration. Possible extensions of the application of this type of histochemical method are discussed.

    Effects of metabolic inhibitors on vital staining with methylene blue (1974)
    Springer
    Histochemistry and cell biology 40 (1974), S. 51-57

    Topics: Biology , Medicine
    Notes: Summary The peripheral innervation of murine skin was vitally stained with methylene blue and the effects of various metabolic inhibitors on the staining process were investigated. The observed effects suggest that uptake of the dye is dependent on the integrity of a membrane-associated adenosine triphosphatase and an unidentified metallo-enzyme. Glycolysis, the citric acid cycle and the cytochrome system are not necessary to the process of vital staining, which also does not involve the conduction of nervous impulses or the rapid axoplasmic transport of protein.
