    Description / Table of Contents: Résumé Del' ATP a été trouvé dans les lavages à l'eau distillée du dos épilé et non-épilé de rats. Cependant, des quantités plus élévées d'ATP sont observées chez les rats épilés. En fonction de ces résultats et de travaux antérieurs démonstrant que l'adénosine 5′ triphosphate de calcium provoque une calcification sous-cutanée chez le rat, une hypothèse concernant le mécanisme de la calcinose cutanée, locale est proposée. L'ingestion de DHT provoque une hypercalcémie généralisée — Si une épilation est ensuite réalisée, un trauma tissulaire se developpe, avec destruction et/ou perméabilite augmentée des membranes cellulaires et rejet d'ATP. Le Ca ATP qui se forme, s'hydrolyse pour constituer une zone de nucléation pour le processus de calcification. La substance, fondamentale, nécessaire pour la formation de la plaque organisée, est constitutuée par les fibres de collagène et les mucopolysaccharides de la matrice interfibrillaire de couche dermique du follicule pileaux lui-même.
    Abstract: Zusammenfassung Das Dorsum von enthaarten und nichtenthaarten Ratten wurde mit destilliertem Wasser gespült. In dieser Flüssigkeit wurde ATP festgestellt. Bei enthaarten Ratten wurde jedoch beträchtlich mehr ATP gefunden. Auf Grund dieser sowie früher mitgeteilter Befunde, wonach Calcium-Adenosin-5′-Triphosphat die subkutane Verkalkung bei Ratten auslöst, wird folgende Hypothese für den Mechanismus der lokalen Hautcalcinosis vorgeschlagen. DHT-Verabreichung führt zu generalisierter Hypercalcaemie. Darauffolgende Enthaarung führt zu Verletzung des Gewebes, was die Zerstörung und/oder erhöhte Permeabilität der Zellmembranen und Abgabe von ATP nach sich zieht. Das dadurch entstehende, CaATP wird hydrolysiert und dabei entsteht ein Calciumorthophosphat-Nukleationskern für den Verkalkungsvorgang. Die Grundsubstanz, welche nötig ist, um mit Calciumphosphat diese Plaque zu bilden, besteht aus Collagenfasern und Mucopolysacchariden der inter-fibrillären Matrix der Hautschicht oder aus dem Haarfollikel selbst.
    Notes: Abstract ATP has been found in the fluid from distilled water washes of the dorsum of epilated and non-epilated rats. However, considerably more ATP was found in the epilated rats. Based upon these and previously reported results demonstrating that calcium adenosine 5′ triphosphate initiates subcutaneous calcification in rats, a hypothesis is proposed for the mechanism of topical cutaneous calcinosis as follows: Feeding DHT results in generalized hypercalcemia. When this is followed by epilation, tissue trauma occurs, resulting in destruction and/or enhanced permeability of cell membranes and release of ATP. The CaATP which forms hydrolyzes to produce a calcium orthophosphate nucleating seed for the calcification process. The ground substance necessary to form with calcium phosphate, the organized plaque, are the collagen fibers and muccopolysaccarides in the inter-fibrillar matrix in the dermal layer or the hair follicle itself.

    Description / Table of Contents: Résumé On note un passage d'ions calcium à travers une solution aqueuse de tétrachlorure de carbone contenant de la vitamine D3: ce passage est accéléré par un anion orthophosphate. En l'absence de vitamine D3 aucun déplacement ne se produit. Dans ce système, la vitamine D3 semble agir comme un agent d'émulsion et cette propriété de la vitamine D3 semble être responsable du passage du Ca2+ à travers l'interface eau-tétrachlorure de carbone.
    Abstract: Zusammenfassung Der Transport der Calciumionen aus einer wäßrigen Lösung findet in Vitamin D3 enthaltendem Tetrachlorkohlenstoff statt und wird durch Orthophosphat-Anionen beschleunigt. Wenn Vitamin D3 fehlt, erfolgt kein Transport. In diesem Versuchssystem scheint Vitamin D3 eine emulgierende Wirkung zu haben. Es wird vorgeschlagen, daß der Transport von Ca2+ durch die Oberfläche zwischen Wasser und Tetrachlorkohlenstoff auf dieser Eigenschaft von Vitamin D3 beruht.
    Notes: Abstract Dassage of calcium ion occurs from aqueous solution through carbon tetrachloride containing vitamin D3, and is accelerated by orthophosphate anion. No movement occurs when vitamin D3 is absent. In this sytem vitamin D3 appears to act as an emulsifying agent, and this property of vitamin D3 is proposed to account for movement of Ca2+ across the water-carbon tetrachloride interface.
