    Notes: Summary Frog sciatic nerves show a continuing addition of new myelinated and nonmyelinated fibers with body growth. Along with increases in fiber number there are also marked changes in axon calibers and in the relative thickness of the myelin sheaths. Our data show that frog nerves, as opposed to mammalian nerves, are composed of fibers of different ages, stages of growth and stages of myelination.

    Mechanism of the congestion of lymph nodes induced by ellagic acid in rats (1987)

    Notes: Abstract Intravenous injection of ellagic acid (EA, 30 mg/Kg), an activator of the Hageman factor, induced congestion of lymph nodes and dilatation of the spleen in rats. The dilatation of the spleen was inhibited by heparin, thrombin, defibrase, clocoumarol. lambda carrageenan, SBTI, PCR 4099 and CCI 17810. The congestion of lymph nodes was inhibited by heparin, thrombin, defibrase, clocoumarol, SBTI, lambda carrageenan, aspirin, indomethacin and ketoprofen, phentolamine and hexamethonium. Thrombin, defibrase, lambda carrageenan did not induce any congestion of the lymphoid tissues. These results suggest that the dilatation of the spleen induced by ellagic acid would result from blood coagulation, platelet stimulation and kinin formation. The congestion of lymph nodes would depend on kinins, blood coagulation and prostaglandins. The activation of Hageman factor in acute inflammatory reactions could mediate the early congestion of lymph nodes.

    Studies on the vascular and hematological changes induced by ellagic acid in rats (1987)
    Springer

    Notes: Abstract We compared the major changes induced by ellagic acid (EA), a Hageman factor activator, in normal rats and in kininogen-deficient Brown Norway rats. In normal rats, large doses of EA induced a congestion of lymph nodes, spleen and liver, a prolongation of activated partial thromboplastin time, the consumption of prekallikrein, high molecular weight kininogen and fibrinogen, as well as the stimulation of platelets with their accumulation in lungs, liver and spleen. A systemic hypotension of long duration was also observed. The fibrinogen consumption, the thrombocytopenia and the lengthening of activated partial thromboplastin time were dose-dependent. In kininogen-deficient rats, EA induced only a minimal congestion of lymphoid tissues, the accumulation of platelets in lungs, a decrease of plasma fibrinogen and a short-lasting hypotension. It is concluded that the vascular changes induced by blood coagulation with ellagic acid resulted mainly from kinin formation.

    Description / Table of Contents: Résumé Cent crânes normaux ont été étudiés sur des radiographies de profil ainsi que dix crânes pathologiques présentant des impressions basilaires chez des patients traités à l'HÔpital Kenyatta de Nairobi. La plus courte distance moyenne entre le sommet de l'odontoÏde et la ligne basale de McGregor a été de 1,2±2,28 mm au-dessous de la ligne basale (extrÊmes étendues de 6 mm au-dessous à 3 mm au-dessus de la ligne basale), chez les sujets normaux et de 9±2,7 mm (6–14 mm) au-dessus de la ligne basale chez les sujets pathologiques. L'angle basai moyen était de 113
    Notes: Summary One hundred normal lateral skull radiographs were studied and those of ten patients with basilar impression attending Kenyatta Hospital, Nairobi. The mean shortest distance of the odontoid tip to McGregor's basal line was 1.2±2.28 mm below the basal line (range 6 mm below to 3 mm above basal line), in normals and 9±2.7 mm (6–14 mm) above basal line in patients. The mean basal angle was 113

    Notes: Zusammenfassung Mit Rücksicht auf die Verdrängung der Köpfchenbakterien durch den Bifidus läßt sich folgendes feststellen. Beide Arten vermögen kräftig Zucker zu vergären und produzieren in Kulturen End-p H-Werte, die wenig voneinander unterschieden sind (Köpfchenbakterien 4,7; Bifidus 4,3). Eine stärkere, endliche Säureentwicklung kann demnach nicht das Ausschlaggebende für die Verdrängung sein. Die Entwicklung beider Arten ist außerdem schon bei geringeren Säuregraden als den Endwerten gehemmt. Das Auftreten des Bifidus—im Grunde handelt es sich um das Problem der Umwandlung der Stuhlflora überhaupt —vielmehr mit der Entstehung und Aufrechterhaltung der Eigenwasserstoffzahl des Bifidus, d. h. der optimalen H-Ionenkonzentration (p H 5,0–5,8), zusammen, die von der der Köpfchenbakterien (p H 6,9–8,2) wesentlich verschieden ist. Die Bedeutung der Eigenwasserstoffzahl erhellt auch daraus, daß sie unabhängig vom Angebot gärungsfähigen Zuckers ist. Sie ist nach Beobachtungen an den Köpfchenbakterien und einer aus dem Dünndarm einer alimentären Intoxikation gezüchteten Coliarten die gleiche auf zuckerfreiem wie zuckerhaltigem Nährboden.

    Notes: Zusammenfassung Es wurden Stuhlproben von 21 gesunden Brustmilchkindern bezüglich des Vorkommens von B. bifidus und acidophilus untersucht. Mit Hilfe einer der Biologie dieser Bakterienarten angepaßten Kulturtechnik konnte ein überwiegendes Vorkommen des B. bifidus festgestellt werden. Die Verdünnung des Stuhlmaterials, in welcher Bifidus gefunden wurde, war im Durchschnitt etwa 100000 mal stärker als die, in welcher der B. acidophilus aerob oder anaerob nachweisbar war.
