    Notes: Summary Extracellular calcium concentration is an important regulator of calcitonin secretion. We used primary cell cultures of human medullary thyroid carcinoma to study the role of voltage dependent calcium channels for stimulus secretion coupling. Increasing extracellular calcium concentration (1.6–5.0 mM) in the medium caused a dose dependent release of calcitonin. The calcium channel activator BAY K 8644, a dihydropyridine, stimulated calcitonin secretion in a dose dependent manner (10−7−10−5 M). This effect was completely inhibited by equimolar concentrations of the calcium channel blocker nifedipine and abolished in the absence of extracellular calcium. Similarly, nifedipine suppressed the stimulatory action of extracellular calcium. The effects of calcium and BAY K 8644 with and without nifedipine suggest that calcium influx via voltage dependent calcium channels plays an important role in calcitonin secretion. The primary cell culture of human medullary thyroid carcinoma is a good model for the study of stimulus secretion coupling.

    Notes: Abstract It is shown, that the use of an energy independent effective interaction in a shell model calculation implies a strongly energy dependent residual interaction and thus a nucleon-nucleon interaction which is strongly energy dependent in the energy region of interest.

    Description / Table of Contents: Summary 253 milk teeth with inflamed gingiva were observed for 19 months (on average) around the time of exfolication and changeover to the secondary dentition. The criteria used were the gingival index byLoe andSilness, the intravital staining of glycogen with iodine solution byZabinska and the plaque index byQuigley andHein. In about one third of the cases, there was residual inflammation following loss of the milk teeth in the original area. With eruption of the permanent teeth, plaque level increased as did the degree of gingival inflammation. On full eruption of the permanent dentition the values fell under their former level.
    Abstract: Résumé On a observé 253 dents de lait avec gencive enflammée pendant 19 mois en moyenne et durant toute la période du changement des dents. Les critères d'examen étaient: l'indice gingival selonLöe etSilness, la teinture intravitale de glycogène par solution d'iode selonZabinska et l'indice de plaque selonQuigley etHein. Dans environ un tiers des cas une petite inflammation persistait à l'endroit où la dent temporaire venait de tomber. Après l'éruption de la dent permanente, l'acculumation de plaque augmentait ainsi que l'intensité de la gingivite. L'éruption de la dent achevée, les valeurs de tous les critères d'examen tombaient au-dessous du niveau initial à l'époque de l'ancienne dent de lait.
    Notes: Zusammenfassung Es wurden 253 Milchzähne mit entzündlicher Gingiva durchschnittlich 19 Monate lang über den Zahnwechsel hinweg beobachtet. Prüfkriterien waren: der Gingiva-Index nachLöe undSilness, die intravitale Glykogenanfärbung mit Jodlösung nachZabinska und der Plaque-Index nachQuigley undHein. Bei etwa einem Drittel der Fälle verblieb eine geringe Restentzündung nach dem Milchzahnverlust am ehemaligen Lokalisationsort des Zahnes. Nach dem Durchbruch des permanenten Zahnes stieg die Plaque-Akkumulation ebenso an wie die Intensität der Zahnfleischentzündung. Mit vollendetem Zahndurchbruch gingen die Werte aller Prüfkriterien unter das Anfangsniveau des Milchzahnvorgängers zurück.

    Description / Table of Contents: Summary 204 children with various degrees of anterior crowding were examined with respect to dental plaque intensity. Criteria used were: Crowding-Index byLundström, Plaque-Index byQuingley andHein (modified), Sulcus-Bleeding-Index byMühlemann andSon. The coefficient of correlation was evaluated for different variables. Age to plaque=0.32, plaque to periodontal condition=0,32, modus of cleaning teeth to plaque=0,38, crowding to plaque=0,40, age to periodontal condition=0,58, crowding to periodontal condition=0,64. All values of cc differ significantly from zero (α=5%).
    Abstract: Résumé On a examiné la formation de la plaque chez 204 enfants ayant un encombrement incisif plus on moins prononcé. On a utilisé comme critères d'examen l'indice d'encombrement derLundström, l'indice de plaque deQuingley etHein modifié et le ‘sulcus-bleeding-index’ deMühlemann etSon. On a déterminé le coefficient de contingence (cc) entre des différents variables: âge-plaque=0,32, plaque-état parodontal =0,32. mode de lavage des dents-plaque=0,38, encombrement-plaque=0,40, âge-état parodontal=0,58, encombrement-état parodontal=0,64. Toutes les valeurs de cc se distinguaient de manière significative de zéro (α=5%).
    Notes: Zusammenfassung 204 Kinder mit unterschiedlichem Ausprägungsgrad des frontalen Engstandes wurden auf ihren Plaquebefall hin untersucht. Als Prüfkriterien wurden verwendet: Engstand-Index nachLundström, Plaque-Index nachQuigley u.Hein modifiziert, Sulcus-Bleeding-Index nachMühlemann u.Son. Der Kontigenzkoeffizient (cc) wurde zwischen verschiedenen Variablen ermittelt: Alter-Plaque=0.32, Plaque-Parodontalzustand=0,32, Zahnputzmodus-Plaque=0,38, Engstand-Plaque=0,40, Alter-Parodontalzustand=0.58. Engstand-Parodontalzustand=0,64. alle cc-Werte unterschieden sich signifikant von Null (α=5%).
