    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

    A laser-induced fluorescence study of bands of the red system of gaseous CoO: Evidence for a 4Δi ground state (1987)

    Notes: Three bands of the "red'' system of gaseous CoO have been rotationally analyzed using laser-induced fluorescence techniques. The available evidence indicates that the lower levels are the Ω=7/2 and 5/2 spin–orbit components of a 4Δi electronic state, which is assigned as the ground state of the molecule. The cobalt nuclear hyperfine splittings are small in the ground state, which suggests that no unpaired electron in a σ molecular orbital derived from the Co 4s atomic orbital is present, so that the electron configuration is presumably σ2δ3π2; the ground state bond length (r0) is 1.631 A(ring). The upper electronic levels are heavily perturbed, both rotationally and vibrationally, and their hyperfine structures, though following case (a) behavior, are large and irregular. This work on CoO completes the determination of the ground state symmetries and bond lengths for the whole series of the 3d transition metal monoxides; some comparisons for the members of the series are given.

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

    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.

    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.
