    Notes: In the present study, we investigated the effects of the cannabinoid receptor agonist CP55,940 on excitatory and inhibitory synaptic transmission in the rat supraoptic nucleus. Whole-cell patch clamp recordings were performed on supraoptic neurones in in vitro brain slice preparations. CP55,940 significantly reduced the frequency of spontaneous excitatory and inhibitory postsynaptic currents in a concentration-dependent manner. These changes were potently reversed by the CB1 receptor antagonist AM251. The results indicate that cannabinoids modulate the activity of magnocellular neurosecretory neurones by presynaptic inhibition of both excitatory and inhibitory synaptic transmission.

    Notes: Background:  Recent studies have reported a relationship between obesity and periodontal disease. Obesity is the strongest risk factor for type 2 diabetes, which is, in turn, a risk factor for periodontal disease. An oral glucose tolerance test is necessary to diagnose diabetes; however, no study has examined the relationship between obesity and periodontal disease by taking oral glucose tolerance test results into consideration.Methods:  In all, 584 Japanese women aged between 40 and 79 years old, with at least 10 teeth, underwent health examinations. Body mass index, waist–hip ratio, body fat, and oral glucose tolerance test results were used as independent variables with known risk factors for periodontal disease. Mean probing pocket depth and mean attachment loss were used as the dependent variables.Results:  In all of the analyses, body mass index, body fat, and waist–hip ratio were significantly associated with the highest quintile of mean probing pocket depth, even when adjusted for oral glucose tolerance test results. In the multivariate analysis, the subjects with the highest quartile of body mass index had a significantly higher odds ratio (OR) for the highest quintile of mean probing pocket depth [OR, 4.3; 95% confidence interval (CI), 2.1–8.9; p 〈 0.001], whereas neither impaired glucose tolerance nor diabetes were significantly associated with deep pockets. The relationships between the obesity indexes and mean attachment loss did not reach statistical significance.Conclusion:  Obesity was associated with deep pockets in Japanese women, even after adjusting for oral glucose tolerance test.

    Description / Table of Contents: Zusammenfassung Klinische Beobachtungen an Patienten, die der präsacralen Neurektomie unterzogen wurden, um sie von der Cystalgie zu befreien, zeigten bemerkenswerte Erfolge und nur geringe Komplikationen dieses Eingriffs. Die Resultate sprechen für eine derartige Operation nach sorgfältiger Indikationsstellung. Darüber hinaus wurden die Mechanismen durch Experimente an Hunden untersucht.
    Abstract: Résumé L'observation clinique de malades qui ont été soumis à la neurectomie présacrale pour les soulager des douleurs de la vessie, a démontré l'efficacité et la rarité des complications chirurgicales. Le résultat indique que l'opération doit être faite après un triage sévère des indications. Les mécanismes d'action ont été, en outre, étudiés au moyen d'expériences sur des chiens.
    Notes: Summary A clinical observation on patients subjected to presacral neurectomy to relieve them from cystalgia showed remarkable effectiveness and slight complications. The result indicates that the operation should be performed, strictly choosing the indications. Moreover, its mechanisms were investigated by the experiment employing dogs.

    Description / Table of Contents: Zusammenfassung Es wurden bei 187 Hunden Durchtrennungen bestimmter Anteile der Blaseninnervation vorgenommen und jeweils die hierdurch bedingten Veränderungen der Blase cystometrisch und gleichzeitig biochemisch ausgewertet. Dabei fiel auf, daß nach Durchtrennung der vorderen und hinteren Wurzeln der entsprechenden Sacralnerven mit gleichzeitiger Entfernung der Sacralganglien Blasenvolumen und Blaseninnendruck sich gleich verhielten wie nach Durchtrennung der Nn. pelvici; d. h. das Blasenvolumen sank und der Innendruck stieg an. Wurden bei Durchtrennung der hinteren und vorderen Wurzeln der Sacralnerven die Sacralganglien jedoch belassen, so stieg das Blasenvolumen an und der Innendruck fiel ab. Biochemisch wurde festgestellt, daß nach Durchtrennung der jeweiligen Blaseninnervation regelmäßig jeweils der O2-Verbrauch die CO2-Abgabe, die Bernsteinsäuredehydrogenase und die Cholinesterase in der Blase sich verminderten, während die Milchsäuredehydrogenase und die P32-Aufnahme in die energiereichen Phosphatverbindungen anstiegen. Diese Relation war nach Entfernung der Sacralganglien nicht mehr nachweisbar.
    Abstract: Résumé Chez 187 chiens nous avons sectionné des rameaux définis des nerfs innervants la vessie et déterminé les modifications consécutives sur la vessie autant au point de vue cystométrique que biochimique. Nous avons observé ainsi que la section des racines antérieures et postérieures des nerfs sacrés correspondants et l'enlèvement concomitant des ganglions sacraux amènent les mêmes modifications que celles que l'on observe après section des nerfs pelviens, à savoir une diminution du volume de la vessie et une augmentation de la pression intravésicale. En respectant les ganglions sacraux et en limitant à sectionner les sources antérieures et postérieure il y a au contraire augmentation du volume vésical et chute de la pression intravésicale. La section des nerfs innervant la vessie amène une chute de la consommation d'oxygène et de la production d'acide carbonique de la paroi vésicale ainsi qu'une diminution de l'activité de la succino-déhydrogénase et de la cholinestérase, alors que l'activité de la lacto-déhydrogènase et la vitesse d'incorporation du P32 dans les composés phosphoriques riches en énergie augmentent. Ces faits ne s'observent plus après suppression concomitante des ganglions sacraux.
    Notes: Summary In 187 dogs we cut through certain branches of the nerves innervating the urinary bladder and we determined the changes caused thereby from a cytometrical and a biochemical point of view. We thus observed that the section of the corresponding ventral and dorsal sacral nerves accompanied by the removal of the sacral ganglions brought about the same changes as those observed after section of the pelvic nerves, i. e., a diminution of the volume of the urinary bladder and an augmentation of the intravesical pressure. Leaving the sacral ganglions and restricting ourselves to the section of the ventral and dorsal roots, we ascertained, however, an augmentation of the vesical volume a diminution of the intravesical pressure. The section of the nerves innervating the urinary bladder brought about a diminution of the consumption of oxygen and of the production of carbonic acid of the vesical wall as well as a diminution of the activity of the succinodehydrase and of the cholinesterase while the activity of the lacto-dehydrase and the speed of incorporation of the P32 into the phosphoric compounds rich in energy augmented. These facts were no more observed after the simultaneous suppression of the sacral ganglions.

    Notes: The deficiency in the variety of available magnetic abrasive results in a narrow range of finishing performance. To break through this difficulty, this research developed iron-based gas-atomized magnetic tools. The magnetic tool has a spherical shape and micro-crevices on the surface. The micro-crevices perform the role of cutting instead of the edges of the existing magnetic abrasive, thereby achieving abrasive-less finishing. This paper studies the finishing performance ofthe developed magnetic tool. Compared to the existing magnetic abrasive, this magnetic tool shows more efficient finishing performance in the internal finishing of SUS304 stainless steel tubes used for sanitary piping systems

    Notes: Recently a technique has been developed to mold aspheric glass lenses by using cemented carbide dies at elevated temperature. The dies are precisely ground by an ultraprecision grinding machine. However the obtained form accuracy is generally around 100nm and is not enough high. In this study, to investigate a possibility of corrective figuring of the dies, a series of experiments of abrasive jet machining of cemented carbide was conducted and fundamental machining characteristics were examined. The used abrasives were fine grains of silicon carbide and aluminum oxide. The silicon carbide abrasives could accomplish a sufficient material removal. Both the material removal rate and the surface roughness increase as the collision angle increases up to 90 degrees. Therefore, in order to obtain a smooth surface finish, it was necessary to take a smaller collision angle and to slow down the material removal rate
