    Notes: Four adult cotton top marmosets fed a purified high cholesterol-high fat diet developed a malabsorption induced osteomalacia which involved the periodontal bone. The alveolar bone changes were denoted histologically by a narrowing and disruption of the cortical and cribriform plates and by the presence of broad bands of osteoid around the remaining compact and spongy bone elements. Radiographically, the changes were represented by a partial to complete loss of the lamina dura and by a greatly increased patch radiolucency of the mandible and maxilla.

    Notes: Gingival biopsies from areas characterized as clinically normal, mild gingivitis, or periodontitis were examined. Immunoglobulin (IgG, IgA, IgM, IgE and IgD) bearing cells at the sulcular and oral epithelium - lamina propria junctions as well as the central lamina propria areas were quantitated. Normal gingiva (P. I. = 0-0·2) contained few lymphocytes and plasma cells. Biopsies from areas of mild gingivitis (P. I. = 0·2-1) were infiltrated at the sulcular epithelium - lamina propria junction by lymphocytes lacking membrane associated immunoglobulins (94 %). Few plasma cells were evident. In contrast, tissue associated with periodontitis (P. I. = 4·0–8·0) contained significant numbers of immunoglobulin bearing lymphocytes (78 %, IgG; 9 %, IgM; and 4 % IgA) and plasma cells (67 %, IgG; 24 %, IgM; and 8 % IgA) distributed throughout all three major tissue areas.These findings indicated that the nature of cellular infiltrates differed in mild gingivitis and periodontitis. The presence of predominantly IgG and IgM containing cells in periodontitis had important implications for the contribution of nonspecific effector mechanisms to the destruction of periodontal tissue.

    Notes: Patients with immune system abnormalities were pair-matched to immunocompetent clinic patients by age and Plaque Index. Clinical examination included comprehensive health histories with summaries of antibiotic experience, Plaque Index (P 1.I.), Gingival Index (G.I.), Periodontal Disease Index (P.D.I.), caries experience (DMF-T) and full mouth radiographic surveys. Efficiency of matching was confirmed as tests of significance between sample means for age (11.3, 11.3) and P1.I. (1.33, 1.34) showed no difference between the immunodeficient and clinic patient groups respectively. No clinical or radiographic evidence of attachment loss was noted in either group. A significant and consistent diference was observed in gingival inflammation and caries experience. The G.I. was lower (x̄=1.05) in immunodeficient patients than that recorded in clinic patients (x̄=1.46) in all pairs. Similar results were observed for caries experience, and 8 immunodeficient patients demonstrated DMF-T scores of zero.

    Notes: Abstract The hand blood flow ( $$\dot Q$$ ) was investigated in response to a wide range of general and local cutaneous thermal stimuli (0–36°C and 4–42°C respectively), the local stimulus consisting of a thermostatically controlled water bath for the right hand (Tw), and the general stimulus, the ambient room temperature (Ta). $$\dot Q$$ was measured at the right wrist by strain gauge plethysmography; it was seen to respond more significantly to variations in Tw than to those in Ta at cold to comfortable ambient temperatures (Ta〈22°C). A paradoxical vasodilatation was observed at Tw=4°C (Lewis' “hunting” phenomenon). The graphs of $$\dot Q$$ versus T at average to high local cutaneous temperatures (Tw 〉 33°C) are remarkably similar, except for an upward shift at successively higher values of Tw. The slope (or vasomotor reactivity) is interpreted as being controlled by variations in Ta. The curves exhibited maximum values at Ta = 31°C. Their subsequent decrease could represent a thermoregulatory adaptation to environment-organism heat transfer, the relative vasoconstriction tending to reduce the transfer. Although the qualitative $$\dot Q$$ response was the same for both sexes, the absolute value of $$\dot Q$$ was generally greater in male than in female subjects.

    Notes: Summary Previous authors have suggested that in certain aquatic birds a transparent nictitating membrane of high refractive index could compensate for the refractive loss of the cornea in water. Measurements of refractive indices, refractive state and curvature carried out on a number of aquatic birds indicate that the nictitating membrane does not have a refractive function; the refractive indices of the cornea and nictitating membrane are very similar (approximately 1.37), the nictitating membrane does not alter the refractive state of the eye, and its curvature, when it is in place in front of the globe, is virtually the same as that of the cornea.

    Description / Table of Contents: Résumé Les constantes de couplage quadrupolaire nucléaire de 14N ont été calculées pour une série de composés azotés à partir de fonctions d'onde ab initio SCF-LCAO-MO (Hartree-Fock) construites sur une base de fonctions atomiques gaussiennes. Les diverses contributions nucléaires et électroniques (provenant des orbitales moléculaires, des atomes, des fonctions atomique de base) au gradient de champ total ont été analysées et reliées aux caractéristiques structurales des molécules considérées. L'effet de la nature de la base de fonctions atomiques sur la précision des gradients de champs calculés a aussi été étudié.
    Abstract: Zusammenfassung Die 14N-Kernquadrupol-Kopplungskonstanten sind für eine Reihe von N-haltigen Verbindungen aus ab initio-Wellenfunktionen, die auf Gauß-Orbitalen basieren, berechnet worden. Die einzelnen Kern- und Elektronenbeiträge zum Feldgradienten wurden untersucht und diskutiert, desgleichen der Einfluß des Typus der Basis auf die Genauigkeit der Resultate.
    Notes: Abstract The 14N nuclear quadrupolar coupling constants have been calculated for a series of nitrogen containing molecules from ab initio SCF-LCAO-MO wavefunctions built on basis sets of Gaussian type atomic functions. The various nuclear and electronic (from MO's, atoms, basis functions) contributions to the total field gradient have been analyzed and their relation to molecular and electronic structure is discussed. The effect of the nature of the basis set on the accuracy of the computed field gradients has also been studied.

    Description / Table of Contents: Résumé L'énergie électronique du formaldéhyde a été calculée ab initio dans une base minimale d'orbitales atomiques de Slater par la méthode de perturbation au deuxième ordre. On a utilisé des orbitales moléculaires S.C.F. symétriques et localisées et des orbitales moléculaires de liaison non S.C.F. La valeur finale de l'énergie varie assez peu avec le point de départ. L'emploi d'orbitales localisées permet d'interpréter les différentes contributions et de sélectionner les plus grandes.
    Abstract: Zusammenfassung Eine ab-initio-Rechnung der Elektronenenergie des Formaldehyd wurde mit einer Störungsrechnung zweiter Ordnung durchgeführt, dabei wurde mit einer minimalen STO-Basis begonnen. Es wurden lokalisierte SCF-Symmetrieorbitale und nicht bindende nicht SCF-Orbitale benutzt. Die Gesamtenergie hÄngt nicht sehr stark von den Ausgangs-MO's ab. Lokalisierte Orbitale ermöglichen es, die grö\ten EnergiebeitrÄge der zweiten Ordnung zu erhalten und die verschiedenen Terme zu analysieren.
    Notes: Abstract An ab initio calculation of the formaldehyde electronic energy is carried out by a second-order perturbation method, starting with a minimum basis set of Slater type atomic orbitals. Symmetry-adapted and localized S.C.F. molecular orbitals and non-S.C.F. bond orbitals are used. The total energy does not depend very much on the starting molecular orbitals. Localized orbitals lead to find out the largest contributions to the second-order energy and to interpret the various terms.
